A ketogenic diet for beginners

A keto or ketogenic diet is a very low-carb diet, which turns the body into a fat-burning machine. It has many proven benefits for weight loss, health and performance, as millions of people have experienced already.1  

Here you’ll learn how to eat a keto diet based on real foods. You’ll find visual guides, recipes, meal plans and a simple 2-week get started program, all you need to succeed on keto.

What “keto” means

Ketosis

The “keto” in a ketogenic diet comes from the fact that it makes the body produce small fuel molecules called “ketones”.2 This is an alternative fuel for the body, used when blood sugar (glucose) is in short supply.

Ketones are produced if you eat very few carbs (that are quickly broken down into blood sugar) and only moderate amounts of protein (excess protein can also be converted to blood sugar).

Ketones are produced in the liver, from fat. They are then used as fuel throughout the body, including the brain. The brain is a hungry organ that consumes lots of energy every day, and it can’t run on fat directly. It can only run on glucose… or ketones.3

On a ketogenic diet, your entire body switches its fuel supply to run almost entirely on fat. Insulin levels become very low, and fat burning increases dramatically. It becomes easy to access your fat stores to burn them off. This is great if you’re trying to lose weight, but there are also other less obvious benefits, such as less hunger and a steady supply of energy, keeping you alert and focused.

When the body produces ketones, it’s said to be in ketosis. The fastest way to get there is by fasting – not eating anything – but nobody can fast forever.

A keto diet, on the other hand, can be eaten indefinitely and also results in ketosis. It has many of the benefits of fasting – including weight loss – without having to fast.

ChecklistWho should NOT do a ketogenic diet?

A keto diet is normally very safe, but there are three groups that often require special consideration:

  • Do you take medication for diabetes, e.g. insulin? More
  • Do you take medication for high blood pressure? More
  • Do you breastfeed? More

Are you a doctor or do you need your doctor to help you with medications on keto? Have a look at our low carb for doctors guide.

 
 
 
 

2. What to eat on a keto diet

Here are typical foods to enjoy on a ketogenic diet. The numbers are net carbs per 100 grams.4 To remain in ketosis, lower is generally better:

Keto diet foods: Natural fats (butter, olive oil); Meat; Fish and seafood; Eggs; Cheese; Vegetables that grow above ground
 

The most important thing for reaching ketosis is to avoid eating too many carbs. You’ll probably need to keep carb intake under 50 grams per day of net carbs, ideally below 20 grams. The fewer carbs, the more effective.

Counting carbs can be helpful at first. But if you stick to our recommended foods and recipes you can stay keto even without counting.

Detailed list of what to eat on keto

 

Try to avoid

Here’s what you should avoid on keto – foods containing a lot of sugar and starch. This includes starchy foods like bread, pasta, rice and potatoes. These foods are very high in carbs.

Foods to avoid on a keto diet: bread, pasta, rice, potatoes, fruit, beer, soda, juice, candy

 
The numbers are grams of net carbs per 100 grams, unless otherwise noted.5

This means that on keto you’ll basically need to avoid sugary foods completely, as well as starchy foods like bread, pasta, rice and potatoes. Just follow our keto diet advice.

Furthermore, the food should primarily be high in fat, and only moderately high in protein (as excess protein can be converted to blood sugar in the body). A rough guideline is about 5% energy from carbohydrates (the fewer carbs, the more effective), 15-25% from protein, and around 75% from fat.6

What to drink

Low-carb drinks

So what do you drink on a keto diet? Water is the perfect drink, and coffee or tea are fine too. Ideally, use no sweeteners, especially not sugar. A small amount of milk or cream in your coffee or tea is OK (but beware of caffe latte!). The occasional glass of wine is fine too.

How low carb is keto?

The fewer carbs you eat, the more effective it is for weight loss, appetite suppression and type 2 diabetes reversal, etc. A keto diet is a very strict low-carb diet, containing less than 20 grams of net carbs per day, and thus it is highly effective.

Here are three possible examples of how low-carb meals can look, based on how many carbs you aim to eat in a day. Note that only the left plate is reliably ketogenic:

 
We recommend starting out by following the dietary advice as strictly as you can. When you’re happy with your weight and health, you could carefully try eating a few more carbs (if you want to). Learn more

3. Why eat keto – the benefits

The benefits of a keto diet are similar to those of other low-carb diets, but it’s more powerful than liberal low-carb diets. Think of keto as a super-charged low-carb diet, maximizing the benefits.

 

Keto and weight lossLose weight

Turning your body into a fat-burning machine has obvious benefits for weight loss. Fat burning is vastly increased, while insulin – the fat-storing hormone – levels drop greatly. This creates ideal circumstances in which fat loss can occur, without hunger.

More than 20 high-quality scientific studies8 show that, compared to other diets, low-carb and keto diets result in more effective weight loss.

Keto and appetite controlAppetite control

On keto you’ll gain a new control over your appetite. When your body burns fat 24-7, it has constant access to weeks or months of stored energy, dramatically reducing feelings of hunger. It’s a very common experience, and studies prove it.9

This makes it easy to eat less and lose excess weight – just don’t eat until you’re hungry. This makes intermittent fasting easy, super-charging efforts to reverse type 2 diabetes and speeding up weight loss. Plus, you’ll save tons of time and money by not having to snack all the time. Many people only feel the need to eat twice a day (often skipping breakfast), and some just once a day.

Not having to fight feelings of hunger can also potentially help with problems like sugar or food addiction, and possibly some eating disorders, like bulimia, as well. At least feeling satisfied can be part of the solution. Food can stop being an enemy and become your friend – or simply fuel, whatever you prefer.

Keto and constant energy and brain performanceConstant energy and mental performance

Ketosis results in a steady flow of fuel (ketones) to the brain, and you avoid big blood sugar swings. This often results in the experience of improved focus and concentration. Any brain fog will be long gone!

A lot of people use keto diets specifically for increased mental performance. Also, many people experience an increase in energy when in ketosis.

On keto, the brain doesn’t need carbs. It’s fueled 24-7 by ketones, a perfect brain fuel for focus and energy.

Low carb and diabetes reversalControl blood sugar and reverse type 2 diabetes

A keto diet controls blood sugar levels, and is excellent for reversing type 2 diabetes. This has been proven in studies.10 It makes perfect sense since keto lowers blood-sugar levels and reduces the negative impact of high insulin levels.

As a keto diet may even reverse existing type 2 diabetes, it’s likely to be even more effective at preventing it, or reversing pre-diabetes.

Low carb and diabetes reversalImproved health markers

There are many studies showing that low-carb diets improve important health markers, including the cholesterol profile (HDL, triglycerides), blood sugar levels, insulin levels and blood pressure.11

These commonly improved markers are connected to something called “metabolic syndrome”, and improvements in weight, waist circumference, diabetes type 2 reversal etc.

My health markers after 10 years on a keto diet

happystomach-800-roundedA calmer stomach

Keto can result in a calmer stomach, less (or no) gas, less cramps and pains, etc.

For quite a few people this is the top benefit, and it usually only takes a day or two to experience it. Learn more

Low carb and weight lossIncreased physical endurance

Keto diets can vastly increase your physical endurance by giving you constant access to all the energy of your fat stores.

The body’s supply of stored carbohydrates (glycogen) only lasts for a couple of hours of intense exercise, or less. But your fat stores carry enough energy to easily last for weeks or even months.

How to maximize endurance on a keto diet

Keto and epilepsyEpilepsy

The keto diet is a proven and effective medical therapy for epilepsy that has been used since the 1920s. Traditionally it was used primarily for children, but recently adults have benefited from it as well.

Using a ketogenic diet in epilepsy can allow people to take less or no anti-epileptic drugs, while still remaining seizure-free. This reduces drug side effects and thus increases mental performance. More

 

More possible benefits

The benefits above are the most common ones. But there are others that are potentially even more surprising and – at least for some people – life changing. Did you know that low carb often normalizes blood pressure, results in less acne, controls migraine, might help with certain mental health issues and helps with a lot more?

Follow the links below for more knowledge, stories and science:

Other potential benefits

There’s even science-based speculation that a keto diet could increase longevity and help treat or reduce the risk of cancer.12 It’s also being used as an experimental treatment for some people with Parkinson’s disease13.

4. How to get into ketosis

 

20 grams of carbs in two waysThere are many things that increase your level of ketosis. Here they are, from most to least important:

  1. Restrict carbohydrates to 20 digestible grams per day or less – a strict low-carb diet. Fiber does not have to be restricted, it might even be beneficial.14  
    How much is 20 grams of carbs? Use our visual guide to find out. Or simply use our keto recipes and meal plans, they are designed to keep you under 20 grams with no counting required.
     
    Note that quite often, just restricting carbs to very low levels results in ketosis. So this may be all you need to do. But the rest of the list below will help make sure that you’re successful.
  2. Restrict protein to moderate levels. On a keto diet you should eat the protein you need, but not much more. This is because excess protein is converted to glucose in the body, reducing ketosis.
     
    If possible, stay at or below 1 gram of protein per day, per kg of body weight – about 70 grams of protein per day if you weigh 70 kilos (154 pounds).15  
    The most common mistake that stops people from getting into ketosis is too much protein. Our keto recipes are designed with the right amount of protein.
  3. Eat enough fat to feel satisfied.16 This is the big difference between a keto diet and starvation, that also results in ketosis. A keto diet is sustainable, whereas starvation is not.
     
    When starving you’re likely to feel tired and hungry and give up, but a keto diet is sustainable and can make you feel great. So eat enough to feel satisfied, and if you’re hungry all the time, you should probably add more fat to your meals (like more butter, more olive oil, etc.). Our keto recipes have the needed fat included.
  4. Avoid snacking when not hungry. Eating more often than you need, just eating for fun and because there’s food around, reduces ketosis and slows down weight loss.
 Though using keto snacks will minimize the damage, and is fine when you’re hungry.
  5. If necessary, add intermittent fasting. For example, skip breakfast and only eat during 8 hours of the day, fasting for 16 hours (i.e. 16:8 fasting) . This is very effective at boosting ketone levels, as well as accelerating weight loss and type 2 diabetes reversal. It’s also usually easy to do on keto.
  6. Add exercise – adding any kind of physical activity while on low carb can increase ketone levels moderately. It can also help speed up weight loss and diabetes type 2 reversal slightly. Exercise is not necessary to get into ketosis, but it may be helpful.
  7. Sleep enough – for most people at least seven hours per night on average – and keep stress under control. Sleep deprivation and stress hormones raise blood sugar levels, slowing ketosis and weight loss a bit. Plus they make much it harder to stick to your chosen diet, and resist temptations. So while handling sleep and stress will not get you into ketosis on it’s own, it’s still worth thinking about.
Bottom line: To get into ketosis, restrict carbs to very low levels, preferably below 20 net carbs per day. This is by far the most important thing for ketosis to occur.

Should you need to increase the effect, implement more steps from the list above, starting from the top.

 

No products required

Note what’s not on the list above: you likely do not need fancy expensive supplements, like MCT oil or ketone supplements. These supplements will in all likelihood not help you lose weight or reverse disease, there’s no evidence for that.

KetoSupplements

Ketone supplements for example, do not lower insulin or blood sugar, and they do not increase fat burning. Thus they hardly help with weight loss or type 2 diabetes reversal.

So people saying that – despite the lack of scientific support – likely have a financial reason to say it. Some of these products are sold under something like a multi-level marketing arrangement, so sales people are entirely paid based on commission.17 Thus they’ll likely tell you that their product is fantastic and has changed their lives and makes you lose weight etc., just like any other miracle supplement in the world. But that’s hardly true. Take all such stories with a grain of salt.

All these ketone supplements might do is possibly improve mental and physical performance for a short time. They do raise blood levels of ketones, an effect that can last for one up to a few hours.

So… I’m not saying don’t buy these supplements, perhaps you do want to try them for yourself, see how they make you feel. But you don’t need them to be successful on keto. And they are probably, for most people, a waste of money.

 
 

5. How to know you’re in ketosis

How do you know if you’re in ketosis? It’s possible to measure it by testing urine, blood or breath samples. But there are also telltale symptoms, that require no testing:

Symptoms of ketosis: dry mouth, thirst, frequent urination

  • Dry mouth and increased thirst. Unless you drink enough and get enough electrolytes, like salt, you may feel a dry mouth. Try a cup of bouillon or two daily, plus as much water as you need. You may also feel a metallic taste in your mouth.
  • Increased urination. A ketone body, acetoacetate, may end up in the urine. This makes it possible to test for ketosis using urine strips. It also – at least when starting out – can result in having to go to the bathroom more often. This is the main cause of the increased thirst (above).
  • Keto breath. This is due to a ketone body called acetone escaping via our breath.18 It can make a person’s breath smell “fruity”, or similar to nail polish remover. This smell can sometimes also be felt from sweat, when working out. It’s often temporary. Learn more

 
Other, less specific but more positive signs include:

  • Reduced hunger. Many people experience a marked reduction in hunger.19 This may be caused by an increased ability of the body to be fueled by its fat stores. Many people feel great when they eat just once or twice a day, automatically ending up doing a form of intermittent fasting. This saves both time and money, while also speeding up weight loss.
  • Increased energy. After a few days of feeling tired (the “keto flu“) many people experience a clear increase in energy levels. This can also be experienced as clear thinking, a lack of “brain fog” or even a sense of euphoria.

 
 

Measuring ketosis

ketone meters
There are three ways to measure for ketones, which all come with pros and cons:


 

1. Urine stripsketostix

Urine strips are the simplest and cheapest way to measure ketosis. It is the first option for most beginners.

Dip the strip in your urine, and 15 seconds later the color change will show you the presence of ketones.20 If you get a high reading (a dark purple color), you’ll know that you’re in ketosis.

Pro: Ketone strips are available in regular pharmacies or via Amazon, and they’re very cheap. A strongly positive test reliably proves that you’re in ketosis.

Con: Results can vary depending on how much fluid you drink.21 The strips don’t show a precise ketone level. Finally, and most importantly, as you become increasingly keto-adapted and your body reabsorbs ketones from the urine, urine strips may become unreliable, even if you’re in ketosis.22 Thus, the test may sometimes stop working – always showing a negative result – when you’ve been in ketosis for several weeks.

Order urine strips at Amazon


 

2. Breath-ketone analyzers

ketonixBreath-ketone analyzers are a simple way to measure ketones23 in your breath. At $169 and up they are more expensive than urine strips. But they are cheaper than blood-ketone meters in the long run, as they are reusable any number of times.

These analyzers do not give you a precise ketone level when used on their own, but provide a color code for the general level.24 You can also hook it up to a computer or mobile phone (newer models) and get an exact ketone number via the app. Research shows that the device gives a decent correlation with blood ketones in most situations.

Pro: Reusable, simple test.

Con: Does not always correlate well with blood ketones. Not always accurate, and can in some situations show entirely misleading values.25 More expensive than urine strips, and higher cost upfront than a blood meter.

Order Ketonix

3. Blood-ketone metersBlood ketone meters: Precision extra and Keto-Mojo

Blood-ketone meters show an exact and current level of ketones in your blood.26 They are the gold standard and the most exact way to measure your ketosis level. The major disadvantage, however, is that they are quite expensive, formerly at least $2 per test.27

Now a new startup, called Keto-Mojo, is offering blood ketone testing for as little as $1 per test. Early reviews are positive, and if you’re concerned about the price of testing, we recommend using the Keto-Mojo meter.

GOOD: Exact, reliable.

BAD: Still expensive (at least $1 per test). Requires pricking your finger for a drop of blood.

How to reach optimal ketosis

Getting into ketosis is not a black or white thing. It’s not like you’re either in ketosis, or out of ketosis. Instead, you can be in different degrees of ketosis, as this chart demonstrates.28 The numbers below refer to values when testing blood ketone levels.

 
The Ketone Zone

  • Below 0.5 mmol/l is not considered “ketosis”, although a value of, say, 0.2 demonstrates that you’re getting close. At this level, you’re still far away from maximum fat-burning.
  • Between 0.5 – 1.5 mmol/l is light nutritional ketosis. You’ll be getting a good effect on your weight, but perhaps not optimal.
  • Around 1.5 – 3 mmol/l is called optimal ketosis and is recommended for maximum mental and physical performance gains. It also maximizes fat burning, which can increase weight loss.
  • Over 3 mmol/l is higher than necessary. It will achieve neither better nor worse results than being at the 1.5–3 level. Higher numbers can also sometimes mean that you’re not getting enough food (“starvation ketosis”). For type 1 diabetics, it can be caused by a severe lack of insulin that requires urgent attention.29
  • Over 8–10 mmol/l: It’s normally impossible to get to this level just by eating a keto diet. It means that something is wrong. The most common cause by far is type 1 diabetes, with severe lack of insulin.30 Symptoms include feeling very sick with nausea, vomiting, abdominal pain and confusion. The possible end result, ketoacidosis, may be fatal and requires immediate medical care. Learn more

 

Optimal ketosis experimentStories about achieving long-term ketosis

Here are the three reports from a 2-month experiment in reaching optimal ketosis:

  1. Experiment: Optimal ketosis for weight loss and increased performance
  2. Four weeks of strict LCHF and ketone monitoring
  3. Final report: Two months of strict LCHF and ketone monitoring

Do I have to reach optimal ketosis to experience the benefits?

In short, no. Many of the benefits, such as weight loss, are experienced at lower levels of ketosis (above 0.5).

However, you might need to reach higher levels of ketosis for high-level physical performance. There’s also a time element involved, it takes weeks or even a few months for the body to adapt completely.31

6. Keto guides

Keto can be really simple, but it helps to learn some basic new skills. How do you prepare easy and enjoyable meals, like keto breakfasts? Have you shunned fat for years and don’t know how to get more in your diet? How do you eat out and still stay keto?

These tips and guides will help you get new skills and answer all the common keto questions.

Keto breakfastBreakfast

How should you start your keto day? If you love bacon and eggs dig in! If you don’t, some great keto breakfasts have no eggs at all.

Have you been told that “breakfast is the most important meal of the day”? Ignore that! If you are not hungry when you wake up, feel free to skip breakfast or just have a cup of coffee. Reduced hunger is common on keto, so don’t worry about skipping any meal.

If you are hungry when you wake up but are short on time, many keto breakfasts are tasty, filling and fast. All keto breakfasts

meals-800-roundedMeals

Hmmm, what to eat for lunch or dinner? Daily meal planning can be as simple as meat, fish or chicken mains with a salad, or vegetable side – with melted butter, cheese, or a yummy full-fat sauce. We have hundreds of choices for delicious keto meals

cheap-800-rounded-1Keto on a budget

Many people believe that keto is expensive, and it can be. After all, good quality food is often more costly than cheaper and unhealthier options. But there are many ways to make keto cheap, and in this guide you’ll learn all about it

Eating more fat on ketoHow to eat more fat

For decades we have been told, wrongly, to fear fat. Now we know fat is satiating, healthy and makes food taste great.

Do you need tips and tricks for how to add fat back into your food? And just how much fat do you need each day? Tip: if you are constantly feeling hungry on a keto diet, eat more fat.

Here’s how to add fat back

bread-800-roundedBread

Bread is one of the most common things that people may miss on a keto diet. But fear not, there are plenty of good bread options that are very low in carbs, and that can be eaten even on a keto diet. Learn more

dining-out-800-rounded-ffDining out

How do you eat keto at buffets, at a friend’s house or at fast­-food restaurants? Avoid the starchy foods (like bread or pasta) and ask for additional natural fat, like butter or olive oil, if you need it. Learn more

7. Potential side effects of ketosis

When you suddenly switch your body’s metabolism from burning carbs (glucose) to fat and ketones you may have some side effects as your body gets used to its new fuel.

Symptoms can include headache, tiredness, muscle fatigue, cramping and heart palpitations. These symptoms are mild and short-lived for most people. Many feel fantastic right away, and if not, there are ways to minimize or cure any side effects.

Another option to reduce potential side effects is to gradually decrease your consumption of carbs over a few weeks. But with a slower start you’ll likely not see as dramatic results or feel the positive benefits as strongly.

Therefore we recommend you stop sugar and starches all at once. You will likely lose a number of pounds within days. While some of the initial rapid weight loss is water weight (reduced swelling), it’s still a highly motivating and inspiring way to start your keto journey.

Keep reading for more about common side effects and how to handle them.

 

cheap-800-rounded-1Keto flu

Almost everyone who starts a keto diet will experience some symptoms of the “keto flu“. This is what you may feel, more or less, a couple of days into a keto diet:

  • Headache
  • Fatigue
  • Dizziness
  • Light nausea
  • Difficulty focusing (“brain fog”)
  • Lack of motivation
  • Irritability

These initial symptoms – should you experience them – usually disappear within a week, as your body adapts to increased fat burning.

The cause of the keto flu is that carb-rich foods can result in water retention (swelling) in the body. When you start a low-carb diet much of this excess fluid is lost. You may notice increased urination, and with that some extra salt is lost too.

This can result in dehydration and a lack of salt, before your body adapts. That’s the reason behind most of the symptoms of the keto flu.

You can reduce or even eliminate these symptoms by making sure you get enough water and salt. One simple way to do this is to drink a cup of bouillon or broth, 1-2 times per day.

More common keto side effects

Apart from the keto flu, there are five more relatively common side effects. They can also be avoided to a large extent, by making sure you get enough water and salt.

Beyond that, there are more specific treatments for all of these issues:

Less common keto side effects

These side effects only affect a small minority of people on a keto diet, and there are ways to handle them:

Keto myths

Most side effects of keto are minor and temporary. But there are a lot of myths, that scare people. Like the idea that your brain will cease functioning unless you eat lots of carbs. It’s a myth, based on a lack of understanding of the way the body works in ketosis (switching the fuel supply of the brain to ketones. Learn more

Another common mistake is mixing up normal ketosis – resulting from a keto diet – with the dangerous medical emergency ketoacidosis. They are two very different things. Ketoacidosis does not happen just from eating a keto diet.32

There are several more common keto myths. Will keto kill your kidneys or destroy your bones? Will it stop your thyroid from working? Read all about them on our low-carb and keto myths page


 

8. Keto Q&A, troubleshooting and resources

Keto questions and answersThere are many common questions about keto, and we do our best to answer them all. Feel free to check out our full keto FAQ, or choose one of the questions below:

 

How much weight will I lose on keto?

Results vary widely. Most people lose 2-4 pounds (1-2 kg) during the first week. This is partially water weight. After this it’s common to lose about 1 pound (0.5 kg) of excess fat weight per week. However, some lose much faster (often younger men), some a bit slower (often women over 40).

You can speed up the process or break a weight loss plateau by following our top tips.

When you approach your normal body weight, the weight loss will slow. As long as you eat when you’re hungry you’ll eventually stabilize your weight even if you stay on a keto diet.

 

How do I track my carb intake?

If you use our keto recipes and keto meal plans you’ll stay under 20 net grams of carbs per day, with no need to count.

Using our keto foods guidelines and visual guides will make it simple to estimate roughly how many carbs you eat in a day.

If you want to count carbs exactly, the most popular way is with apps like MyFitnessPal or Chronometer.

 

What happens after I reach my health and weight goals on keto?

Once you reach your goals you can either keep eating keto (to maintain the effect), or you can try adding a bit more carbs. In the latter case the effect of the keto diet will be slightly weaker, and you may or may not regain some weight.

If you completely revert to your old habits, you’ll slowly return to the weight and health situation you had before. It’s like exercising – if you stop doing it, you’ll slowly lose the benefits. As you may expect, keto, like exercise, only works when you do it.

  1. Scientific studies now prove that compared to other diets, low carb or keto is more effective.

    Here are two of the top studies showing more weight loss and improvements in health markers on low carb or keto:

    Similar results have been found in meta-analyses of all studies, for example this recent analysis:

    PLOS ONE 2015: Dietary Intervention for Overweight and Obese Adults: Comparison of Low-Carbohydrate and Low-Fat Diets. A Meta-Analysis

    Here are many more studies on the topic:

    The science of low carb

    Hundreds of success stories that people have sent us: low-carb success stories

    It’s safe to say that millions have experienced the potential benefits, as strict low-carb diets have been popular all over the world for decades, if not more.

  2. There are three different ketones, or “ketone bodies” used as fuel by the body. They are:

    1. Acetone
    2. Acetoacetate
    3. Beta-hydroxybutyrate

    Ketones

  3. The brain consumes about 20% of the body’s required energy every day, despite only representing 2% of the body’s mass.

    A good bonus for weight loss, if you can get your hungry brain to burn fat for you, 24-7.

    Another note: ketosis is why the old idea that “the brain needs carbohydrates” is simply wrong.

  4. Net carbs per 100 grams, i.e. what percentage of that food that is made up of digestible carbs.

    100 grams = 3.5 ounces.

    Net carbs (or “digestible carbs”) are total carbs minus fiber. Fiber is OK to eat since it doesn’t affect blood sugar levels.

  5. Net carbs per 100 grams, i.e. what percentage of that food that is made up of digestible carbs.

    100 grams = 3.5 ounces.

    Net carbs (or “digestible carbs”) are total carbs minus fiber. Fiber is OK to eat on keto, since it doesn’t affect blood sugar levels.

  12. Here are a couple of pilot studies where a ketogenic diet was used in cancer patients. The conclusions are that an insulin-inhibiting diet is safe and feasible in selected patients with advanced cancer.

    In brain cancer in particular the ketogenic diet looks like a promising addition to other treatments:

    NOTE: This is only an experimental additional treatment of selected cancers, with highly limited evidence. Many conventional cancer treatments (surgery, chemo etc.) are highly effective and they often offer excellent chances of a cure when used in early stages of the disease. To turn down such treatment would be a mistake that could easily be fatal.

  13. A small pilot study of five people with Parkinson’s disease showed clear improvement of symptoms on a ketogenic diet. There was no control group, so a placebo effect can’t be ruled out.
    Vanitallie, TB et al. Treatment of Parkinson disease with diet-induced hyperketonemia: a feasibility study. Neurology, 2005.

  14. Fiber is digested by bacteria in the colon, and some of it is transformed into a fat called medium-chain triglycerides. This fat can be absorbed by the body and is very effective at turning into ketones. Thus eating more fiber (but still very low carb) could result in higher ketone levels in the blood.

  15. It might be beneficial to lower protein intake even more, especially when overweight, and then aim for 1 gram of protein per kg of desired weight.

  16. Here are two guides that may be helpful to you:

    Keto fats and sauces – the best and the worst

  17. For example, the company Prüvit sells drinkable ketones, called KETO//OS with a multi-level marketing structure.
     

    Pruvitnow.com

  18. This can sometimes be measured as early as during the first day on a ketogenic diet:

    AJCN: Breath acetone is a reliable indicator of ketosis in adults consuming ketogenic meals. (2002)

  19. This has been clearly demonstrated in several scientific studies:

    Obesity Reviews: Do ketogenic diets really suppress appetite? A systematic review and meta-analysis (2014)

  20. The strips measure for the ketone type acetoacetate. The presence of this in your urine indicates that you’re been in ketosis during the hours before testing.

  21. By drinking more water, you dilute the concentration of ketones in the urine and thus a lower level of ketones will be detected on the strips.

  22. This happens when the body becomes more adapted to using ketones, meaning that they increasingly stay in the blood to be used as energy instead of being lost through the urine.

    After 3 weeks the kidneys have been found to excrete ketones at one third the rate than after just 4 days despite having the same blood ketone levels:

    Diabetes 1985: Ketone Body Production and Disposal in Diabetic Ketosis: A Comparison with Fasting Ketosis

  23. Breath analyzers measure the ketone acetone.

  24. For example, the Ketonix meter reflects the following levels of acetone:

    • Blue – negative
    • Green – mild ketosis
    • Yellow – moderate ketosis
    • Red – deep ketosis

  25. For example, if you recently ate a lot of carbs e.g. a pizza, this can result in misleading high values on the Ketonix.

  26. Blood-ketone meters measure the ketone beta-hydroxybyturate (BHB).

  27. A meter with 10 ketone-test strips and 30 needles included, used to cost about $110 and then an additional $2 per test after that.

  28. The chart is from the excellent book The Art and Science of Low-Carbohydrate Performance by Professor Stephen Phinney and Jeff Volek. Highly recommended.

  29. Take insulin, eat carbs (if your blood glucose isn’t already high), and contact medical services immediately.

  30. Other possibilities include doing a strict keto diet while breastfeeding or on a class of diabetes medications called SGLT-2 inhibitors (e.g. Farxiga, Jardiance, Invokana).

  31. For more on this, here’s an interesting article from two of the top keto researchers in the world, Stephen Phinney and Jeff Volek:

    Virta Health: Keto-Adaptation – Some Clues to Its Complexity

  32. By far the most common cause is having type 1 diabetes and taking too little insulin.

    In rare cases ketoacidosis may also happen on a keto diet, but normally only when combined with other predisposing factors:

    • Breastfeeding on a keto diet (don’t do a strict keto diet when breastfeeding)
    • Medication with SGLT-2 inhibitors for type 2 diabetes

    Hello, if adding fat is simply a means of adding extra calories (which I guess it is with the exception of essential omega 3s etc) does a ketogenic diet circumvent the need for meeting BMR requirements or worrying about metabolic adaptation to less calories? I am not hungry whilst meeting my protein requirements and getting lots of leafy greens (and cheese, nuts, butter etc) but I can do this well under 1200 calories per day. Any suggestions would be greatly appreciated!

    Hi, i am on type 2 diabetes. i have been on LCHF for about a week. My ketone level when i had my urine tested was 4+. How do i get it down or rather to an optimal level. Any recommendations are much appreciated. And another question, how much of fat is required or recommended for each meal. Thank you.

    It looks like diet doctor has changed its stance on ketogenic diets that it was promoting originally. The article above dies not line list positives and negatives clearly.and the authors it promoted earlier are treated differently now. Any particular reason behind this.

    Hi Josephine, not sure if you have had a reply... No you have to replace the calories you would get from carbohydrates with good fat sources such as oily fish, avocado, olives, olive oil, coconut oil, nuts and seeds etc. Stick to your BMR guidelines, over eating is over eating and will usually result in weight gain. The bonus of the keto diet, LCHF + moderate protein, is that you feel fuller for longer and should not have cravings like you may on other calories resticted diets.
  5. Jane
    Hi Afiq, firstly have you been adn discussed this with your doctor. If not please do so prior to changing your diet. Dietary changes may affect any medications may be taking which must be monitored by your doctor. Once cleared to go ahead the ratios have been detailed in the script above. There is alot of information and I suggest you read it. Not easy to summarise in to two sentences...
  6. Maureen
    Is there a difference between the "Low Carb" and the "Keto" diets as explained on this site? It is my understanding that the Low Carb diet would put you into ketosis, so then is the "Keto" diet even MORE low carb? Could you please provide a comparison between the two if they are different? Thanks!

  7. Keto is a very strict low-carb diet, that also puts even more emphasis on moderating the protein intake, and a few other things.

    A regular strict low-carb diet will likely put most people in ketosis anyway. But a keto diet tweaks things even further to make sure it's working and to get even deeper into ketosis.

    I've added this to the Q&A section above.

  8. I don't feel we've made any substantial changes in how we view ketogenic diets, except of course learning more and tweaking our approach based on new knowledge. I'd be interested in finding out what in particular you feel is different?

    Regarding listing positives and negatives clearly, this page is relatively new and we'll rapidly iterate and improve it during the upcoming months. Thanks for the suggestions.

    Hello,
    I think your site is great, explains great! Thank you!
    I am wondering about salt intake, what kind do you suggest or does it matter? I normally use Himalayan salt.

    Also 9 yrs ago I had emergency surgery which I was in hospital nine days and was only on IV fluids and P.O fluids, I lost weight..related to the constant nausea caused by ill effect from anesthetic, (I think). The unplanned benefit..." I had lost the love handles.." What did I unintentionally actually do? Was I in ketosis?

    For easy calculation of counting carbs and protein, what do you suggest? Any apps?

    Hi. Today I bought a urine ketone test for the first time and I am overjoyed to be sitting between the 1 and 2. This is great motivation to continue with IF and try and get to the deep purple. My question is this: I remember a while back reading somewhere something about how urine ketone testing is a delayed form of testing and the results are representative of a few hours ago. Now I can't find the full proper details on this topic. Can you perhaps guide me better in this regard? Blood and breath tests are outside my budget at this point.

    Hi Eloise!

    I believe it's a good idea to take the test in the morning before you eat your first meal. In that way your tests are made under the same conditions every day.

    Good day.
    I have been on a prescribed diet that basically kept me in a keto state for 11 weeks. This came with weekly shots to 'help weight loss'. The diet forces me to eat 3 meals a day, plus 2 - 3 snacks (chicken vienna, cheese or just something) in between. I got all of my recipes from your website and followed the diet vigorously; including cutting out of all caffeine initially (I am quite a coffee head). In the first 4 weeks I managed to lose 3 kilograms, but have since picked all of that up again, plus some more. The lady at the diet clinic insists that I am eating too little, but I have never suffered from a big appetite, so now I'm forcing myself to eat.
    Can it be that I am doing something wrong? Should I maybe stop with this for a while and then pick it up again? I am desperately trying to lose the baby weight, but feels like an endless battle right now.
    Any advice would be greatly appreciated!

    Hi Andrike!

    If you are following the diet to lose weight then it sounds odd that you are forcing yourself to eat?
    What we are saying is eat only when hungry.

    If you have other health related problems then you should follow the advice given from your physician.

    Dear Peter
    Thanks for your speedy response!
    I do have hypothyroidism (had my thyroid removed because of aggressive cancer) have been on hormone replacement since. I get my TSH, T3 and T4 done regularly, because it does influence my weight loss. But all is well there.
    If I should only eat when I'm hungry, but I don't have much of an appetite, isn't it bad for the metabolism to skip regular meals?
    What about drinking coffee with unsweetened cream and honey? I do overindulge a bit and that might have an influence on my appetite I suppose.

    Drinking coffee with unsweetened cream is a good idea, but avoid the honey. :)

    Hello, I’ve started my keto diet nine days ago and I transitioned to ketosis 6 days ago. I have no doubt that I’m in ketosis now, as I present all the symptoms (the smell of my urine, that strange taste in my mouth, increased thirst). Despite this, I still don’t see any of the positive effects of ketosis in terms of increased mental energy, which was the reason that prompted me to start it in the first place: I just feel normal, in no way more focused or clear headed than I usually am. Do I just need to wait a few more days or, maybe, my body’s response just doesn’t include those positive effects on brain activity?
    Thanks!

    I really enjoyed Dr.Wilson's video on resistance training and ketosis. Having reached the body fat percentage I was targeting I started eating carbs more than during my fat reduction phase. After seeing his presentation on cycling in and out of ketosis I think I'd like to remain more in than out. Strength training to failure is my primary form of exercise.

    After having cheated significantly this weekend to the tune of ice cream on Friday and four pints of craft beer on Saturday. I'd like to know if a fast on the day after a cheat of that magnitude is appropriate or harmful.

    I completed a fasting full body workout by mid afternoon. Is an intermittent fast allowable on the same day as such a workout?

    Is there risk of muscle loss if one fasts the entire day of a strength training workout?

    DEAR TEAM LCHF DOCTORS

    My name is Gina and I'm writing from South Africa and YES I do think there is SOMETHING MISSING FROM the diet Doctor site that is VERY IMPORTANT ..

    I have scoured the internet and there are hundreds of KETO and LCHF sites , (yours being one of the best I must add,) but I haven't found ONE site where a MEDICAL DOCTOR addresses the problem of doing KETO or LCHF without a gallbladder in any detail .So many doctors talk about how High FAT reduces chances of getting gallstones and how to save your gallbladder but nothing is written about following a High FAT diet without gallbladder !

    WHY ?

    There must be thousands of people like me out there who do not have a gallbladder and want desperately to stop their addiction to sugar and carbs and try the LCHF but when they try have constant diarrhea , or see an oil slick in the toilet after bowel movement and many other problems ...related to having no gallbladder, they get worried and wonder if they need to stop.

    I am fully aware that it is not simple to talk about doing LCHF without gallbladder because everyone is different and handles FAT differently -- But surely there must be a doctor somewhere who has studied this area, and has treated patients without gallbladders ?
    We need a doctor who will help us by teaching us :

    1) What could possibly happen when the 70 % fat enters a body without gallbladder
    MENTION the various scenario's that could occur .
    2) Is it True that no gallbladder always means that a 70% FAT meal will not be digested properly by the body leading to fat soluble vitamins like A , D, K being flushed out of the body with the waste , thus leading to Vitamin defiency ?
    3_ Is it true that our liver will not be able to break down the fats efficiently so we will not be able to get into the state of KETOSIS like those with gallbladder ?
    4- Is it true that because of this fat digestion problem our bodies will not be able to use Ketones as alternative fuel ?
    5) Is it true that because it will be much harder for us to enter KETOSIS we will be much much slower than normal people to lose weight or that we might not lose weight at all?
    7) What are the markers to look for that your liver is not digesting the fat, and when you see this what can you do about it ?
    6) How does a person without a gallbladder go about beginning the LCHF lifestyle ?
    8) Do we need to take bile salts ?
    9) Are bile salts a solution -and after we take them will we be digesting fats normally again and enter KETOSIS like normal people. ?

    Tell us about different types of bile salts - .
    a) how they work ?
    b) and if must WHEN and HOW must we take them ?

    10) Is it true that you need to increase the fat slowly to see your tolerance level and that the will eventually adapt to high levels of fat ? If this is so can we be given an example as to what level we must start with and by how much to increase?

    I would like to CHALLENGE all of the ground breaking and pioneer doctors believing in the LCHF lifestyle to address the issue of NO GALLBLADDER and LCHF

    After all , it is YOU more than any other doctors , that tell us that overeating sugars and carbs is one of the main reasons we LOST our gallbladders in the first place !

    I am a 53 year old post menopausal woman ,30 kg overweight, who has high insulin and is on the way to becoming a Type 2 diabetic and I am unable to control my appetite for chocolate and cakes and biscuits -- LCHF has given me HOPE
    I really believe LCHF will help me but am so afraid I will be harming my body and having endless diarrhea .

    Please help me and all the others without gallbladders

    Thank you for your time

    I was 200 lbs in march i started a supplement called keto/os to help add ketones to my body i choose to add a supplemental form of ketones because being a nurse i know getting to ketosis is difficult and I wanted to see results faster. I was not able to excersie due to 3 pelvic fractures due to a MVA in November but was fixing to go back to work so i needed to feel better soon in order to take care of my patients this was my driving point to look into the keto life style and supplementation. I have to say that not only have i lost weight (38 lbs in 5 months) but my joints don't hurt as bad, my skin looks so much better i have to say all around i feel better, I think we have been taught wrong on how to eat healthy I think that more people will start eating keto diet as word spreads that ketosis is different than DKA

    Hi Irfan!

    I think it depends...but for most people who are not very physical active a moderate LCHF diet is not ketogenic. That means mainly glucose is used.

    Dear Sirs,
    I'm on LCHF (netto beetwen 40 - 50 gr carbs) for 10 months. Everything is fine (as 61 years old man I got the best body of my life, exercising 5 days in a week, after loosing belly fat I got 3 kg on the right places). But.
    Whenever I talk with some nutrition practioner in my country which know keto and LCHF, they warns me about diet on a long term. Main problem they've founded is loosing a good gut bacteria because of not enought prebiotics and probiotics in food intake. Although I eat a lot of vegetables (at least 0,8 kg or more daily) those statments bodered me somehow and decrease my happines.
    And there is another one. Some of them told me, that cancida (which was guilty for begining my LCHF diet) can eat ketones just fine and I just don't feel candidas present in my body now. Have you any statement on this?
    best regards,

    Hello! I am interested in following this diet. A couple questions.....I'm lactose intolerant so dairy is out. The other biggie.....I don't like eggs unless they are cooked "in" something. Is it going to be impossible for me to follow this?
  31. Karen Henell
    Hi Kim,
    Not at all impossible! Plenty of great non-dairy choices for you. And are you perhaps able to eat butter, since it is lactose-free? Otherwise, olive oil, avocado oil, and coconut oil as well as animal fat are all fine fat choices. I make a lot of frittatas (beaten eggs binding meats and vegetables, an easy skillet dish with plenty of butter, olive oil or coconut oil) which takes the emphasis off the eggs. Also easy to store the leftovers for a portable lunch or easy next meal.
    Browse the recipe section for ideas.
    Good luck!

    I tried low carb before...I joined a group and they were all about FAT FAT FAT! I can't just eat a spoon full of butter or oil...and I can't have heavy cream at all or I am running to the potty. (I got very sick because of this last time, sparing the details it ended my low carb attempt). Is it possible for this to be effective for me if I'm not guzzling copious amounts of fat?

    I have gained 20lbs two yeas ago and I seem to be unable to get rid of it. I got a fitbit. I track my water intake. I have counted calories. I have tried low carb. I have less motivation with every failed attempt. I need to know this will work. (also what if grain fed meats are not always an option?)

    I have been eating a LCHF diet for four months. I had my gallbladder removed two years ago and was nervous about eating a high fat diet. However, after about a week on the LCHF diet, my system adjusted and now I have no symptoms of gastrointestinal distress whatsoever. As a caveat, I did take a couple of capsules of oxbile that first week which seemed to help. I have not had any problems since and don't even worry about eating fat anymore.

    not miss the reply (since we don't see one yet-understandably-and don't know what day it will appear?

    Hi Sherrill!

    We don't recommend sweeteners on daily basis. If you use sweeteners occasionally I don't think it matters so much what you are using. :)

    Which low calorie sweetener do you recommend, thanks!

    I just started the strict keto diet on Monday and by Wednesday I started having loose diarrhea. Is this one of the side effects?

    are there any proven or supposed disadvantages / cons for ketogen nutrition ?

    e.g. fat concretion ?

    or known "do NOT do this" things .. e.g. use the wrong fat ?

    why do many people recommend coconut fat ? it is quite saturated ... there are much better fats like coconut oil .. how about olive and linseed oil ?

    Hi Christine!

    Normally what you can do is eat more fat and less of the other stuff or do fasting for a prolonged period.

    I tried a very low carbohydrate diet with mixed results. It started out brilliantly. I lost weight all over, but especially around my belly. I also seemed to have phenomenal amounts of energy. I am a keen trekker and there were days once I got started when I felt like I could walk forever. Nothing was ever a problem. Once I remember I walked six-hours non-stop, then performed a hundred squats when I arrived home, on just a Greek salad with plenty of feta and olives and a double espresso. It was like I was flying. In general, it seemed that I could literally feel myself burning fat every time I went out the door. I was totally sold. It felt like such a revelation.

    Unfortunately I had no sooner hit my stride than the heart palpitations kicked in. At first I would get them when I was asleep, waking in the middle of the night feeling like I'd been run over by a truck. My heart would be flopping about in my chest like a dying fish. If I got up to use the bathroom I would feel so weak and dizzy that I would have to hold onto something in order to stand up. They didn't happen every night, but tough walks or exercise sessions seemed to bring them on. Still at that stage they occurred seldom enough that they didn't feel like a problem.

    Gradually however the palpitations began happening more frequently and not only at night. They often struck while I was exercising. Suddenly I would experience the telltale 'heart in the mouth' sensation and would suddenly feel like a wreck and, if I was going hard, would often have to stop and catch my breath. Often I was able to walk them off, only to have them come back again at night when I lay down in bed. In fact, there were times when lying down seemed to trigger them as reliably as exercise.

    I stuck at this for six months. At times I stopped exercising, thinking I would give myself time to adapt. And there were times I added in some starchy carbohydrate, specifically sweet potato and black beans, which immediately fixed the palpitations. But as soon as I went back to low carb, fifty or sixty grams a day, they immediately returned. At first I probably didn't eat enough food as I was often not hungry and also amazed at how well I felt and keen to push the boundaries. But later on when the palpitations became a problem I began eating an avocado a day and eight or nine cups of vegetables, plus nuts such as almonds and walnuts and heaps of butter and olive oil. I also added plenty of salt. All to no avail. It was uncanny and frustrating. I was eating healthier than I ever had in my life, but unless I upped the carbs the palpitations persisted.

    In the end I became fed up with not being able to work out hard and added back the starch. I am not finished with low carb and will certainly try it again, but for the time being I'm going to back off while I do a bit more research and analyse my experiences in search of what's been going wrong.

    I don't know if there's any lessons to be drawn from this. I am fifty-two years old and before going low carb I used to fuel myself on rice and pasta and bread and legumes. There must be some insulin resistance there. Yet funnily enough I didn't seem to take long to adapt to fat-burning once I cut all that stuff out. Nor did I experience any cravings. I just felt good. It was so disappointing therefore when the palpitations upset the cart.

    All the best,

    Ian

    Great website. I've been using this diet plan to lose weight and I've already dropped 45 lbs. The best part is I really love the food more than I did the other junk I was eating. I also found this really cool iPhone app called "Ketotitian" that shows you the relative contents of carbs, proteins, fats, etc. in a bunch of different foods. I use it all the time now to help plan meals so I can stay within my diet plan and still find lots of good things to eat.

    Thanks for a great website!
