A Ketogenic Diet for Beginners

A Ketogenic Diet for Beginners

A ketogenic diet (keto) is a very low-carb diet, which turns the body into a fat-burning machine. It has many potential benefits for weight loss, health and performance, but also some potential initial side effects.

A ketogenic diet is similar to other strict low-carb diets, like the Atkins diet or LCHF (low carb, high fat). These diets often end up being ketogenic more or less by accident. The main difference between strict LCHF and keto is that protein is restricted in the latter.

A keto diet is designed specifically to result in ketosis. It’s possible to measure and adapt to reach optimal ketone levels for health, weight loss, or for physical and mental performance. Below you can learn how to use keto to achieve your personal goals.

What is Ketosis?

KetosisThe “keto” in a ketogenic diet comes from the fact that it makes the body produce small fuel molecules called “ketones”.1 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,2 and it can’t run on fat directly. It can only run on glucose… or ketones.

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 obviously great if you’re trying to lose weight, but there are also other less obvious benefits, like for example less hunger and a steady supply of energy.

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 obviously it’s not possible to fast forever.

A ketogenic 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?

Most people can safely do a ketogenic diet. But in these three situations you may need extra preparation or adaptation:


The Benefits of a Ketogenic Diet

The benefits that come from a ketogenic diet are similar to those of any strict low-carb diet. However, the effect might be even greater since protein is more restricted. This raises ketones more, and lowers insulin (the fat-storing hormone) more.




Weight loss

Weight-lossTurning 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.

Around 20 scientific studies of the highest class (RCTs) show that, compared to other diets, low-carb and ketogenic diets result in more effective weight loss.3

Diabetes type 2 reversal

reverse-t2-diabetes-1200A ketogenic diet is excellent for reversing type 2 diabetes,4 since it lowers blood sugar levels and the negative impact of high insulin levels.

Improved mental focus

Ketosis results in a steady flow of fuel (ketones) to the brain. And on a ketogenic diet you avoid big swings in blood sugar. This often results in the experience of increased focus and improved concentration.

A lot of people specifically use keto diets specifically for increased mental performance.

Interestingly, there’s a common misperception that eating lots of carbs5 is needed for proper brain function. But this is only true when ketones are not available.

After a few days (up to a week) of keto-adaptation – during which people may experience some difficulty concentrating, have headaches and become easily irritated – the body and brain can run effortlessly on ketones.

In this state many people experience more energy and improved mental focus.


Increased physical endurance

Ketogenic 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.

When you’re adapted to burning primarily carbohydrates – like most people are today – your fat stores are not easily available, and they can’t fuel your brain. This results in constantly having to fill up by eating before, during and after longer exercise sessions. Or even just to fuel your daily activities and avoid “hanger” (hungry and irritable).

On a ketogenic diet this problem is solved. As the body and brain can easily be fueled 24/7 by your powerful fat stores, you can keep going forever like the Energizer Bunny.

Whether you are competing in a physical endurance event, or just trying to stay focused on reaching some other goal, your body has the fuel it needs to keep you going and going.

Two problems

So how is it possible that most people believe that carbs are necessary to perform exercise? There are two reasons. To unlock the power of ketogenic diets for physical endurance, and not instead suffer reduced performance, you need:

  1. Enough fluid and salt
  2. Two weeks of adaptation to burning fat – it does not happen instantly

Metabolic syndrome

There are many studies showing that low-carb diets improve markers of metabolic syndrome6 such as blood lipids, insulin levels, HDL-cholesterol, LDL particle size and fasting blood sugar levels. Improvements have been shown to be even greater when carbs and protein are restricted to a the point of being steadily in nutritional ketosis.



The ketogenic diet is a proven medical therapy for epilepsy that has been used since the 1920s. Traditionally it has mainly been used in children with uncontrolled epilepsy despite medication.

More recently it has also been tested successfully by adults with epilepsy, with similar good results. There are many randomized controlled trials that demonstrate the effectiveness of the ketogenic diet in decreasing seizures in patients with epilepsy.7

Using a ketogenic diet in epilepsy is that usually allows people to take less anti-epileptic drugs, while remaining seizure-free. It’s not unusual to even be able to completely stop taking these drugs while staying seizure-free.

As all anti-seizure medications have side effects – like drowsiness, reduced concentration, personality changes or even reduced IQ – being able to take less or no drugs can be hugely beneficial.

What Do You Eat on a Ketogenic Diet?

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

Low Carb Keto Foods

The most important thing to reach ketosis is to avoid eating most carbohydrates. You’ll probably need to keep carb intake to under 50 grams per day of net carbs,13 ideally below 20 grams. The fewer carbs the more effective.

This means you’ll need to completely avoid sweet sugary foods, plus starchy foods like bread, pasta, rice and potatoes. Basically follow the guidelines for a strict low-carb diet, and remember it’s supposed to be high in fat, not high in protein.

A rough guideline is below 10% energy from carbohydrates (the fewer carbs, the more effective), 15-25% protein (the lower end is more effective), and 70% or more from fat.

How to Know You’re in Ketosis

How do you know 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.
  • Increased urination – another ketone body, acetoacetate, can 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.14 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.15 This may possibly be caused by an increased ability of the body to be fueled by its fat stores. Many people feel great while eating 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 – perhaps 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 as a sense of euphoria.


How Do You Measure Ketosis?

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

  1. Urine strips
  2. Breath ketone analyzers
  3. Blood ketone meter


1. Urine stripsketostix

Urine strips is the most simple and cheap way to measure ketosis. It is the first option for most beginners.

You dip the stick in your urine, and 15 seconds later the color change will tell you the presence of ketones.16 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.17 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.18 Thus the test may sometimes stop working – always showing a negative result – when you’re been in ketosis for several weeks.

Order urine strips at Amazon


2. Breath ketone analyzers

ketonixBreath ketone analyzers is a simple way to measure ketones19 in your breath. At around $150 they are more expensive than urine strips. But they are cheaper than blood ketone meters in the long run, since they are reusable any number of times.

These analyzers do not give you a precise ketone level, but rather a color code for the general level. Research shows that there is decent correlation with blood ketones in most situations.

Pro: Reusable, simple test.

Con: Does not always correlate well with blood ketones. Not accurate, and can sometimes show entirely misleading values. More expensive than urine strips upfront than blood meter. Not portable, needs computer hookup to read..

Order Ketonix


Using Breath Ketone Analyzers


3. Blood ketone metersprecision xtra

Blood ketone meters show an exact and current level of ketones in your blood.20 They are currently the gold standard and the most exact way to measure your ketosis level. The major disadvantage, however, is that they are quite expensive: A meter with 10 test strips included costs about $100 and then an additional $3 per test after that.

GOOD: Exact, reliable.

BAD: Expensive. 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.21 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.
  • Values of over 3 mmol/l aren’t necessary. That is, they will achieve neither better nor worse results than being at the 1.5–3 level. Higher values 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.22
  • Values of over 8–10 mmol/l are usually impossible to get to just by eating a ketogenic diet. It means that something is wrong. The most common cause by far is type 1 diabetes with severe lack of insulin.23 Symptoms include feeling very sick with nausea, vomiting, abdominal pain and confusion. The end result can be a state called ketoacidosis, that may be fatal. Needless to say abnormally high ketones requires immediate medical care. Learn more


How to achieve ketosis

There 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.24
  2. Restrict protein to moderate levels. If possible stay at or below 1 gram of protein per day, per kg of body weight. So about 70 grams of protein per day if you weigh 70 kilos (154 pounds). 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. The most common mistake that stops people from reaching optimal ketosis is too much protein.
  3. Eat enough fat to feel satisfied. This is the big difference between a ketogenic diet and starvation, that also results in ketosis. A ketogenic diet is sustainable, starvation is not.
  4. Avoid snacking when not hungry. Unnecessary snacking slows weight loss and reduces ketosis.
  5. If necessary add intermittent fasting, like 16:8. This is very effective at boosting ketone levels, as well as accelerating weight loss and type 2 diabetes reversal.
  6. Usually not necessary: Supplement MCT oil and/or Bulletproof coffee.
  7. Usually not necessary: Supplement exogenous ketones.25

Two stories about achieving long-term 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

Here’s a great ten-minute presentation about self-tracking one year in nutritional ketosis:

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 (at least above 0.5). There are indications that you might need to reach higher levels of ketosis for high-level physical performance.

A master class in ketosis

Potential Side Effects of Ketosis

Can ketones get too high, dangerously high? Not under normal circumstances.

For most people it’s quite a challenge to even get to optimal ketosis. Getting into dangerously high ketone levels (more than 8 – 10 mmol/l) is most often simply impossible. The main exception is type 1 diabetes, where the pancreas does not produce enough insulin. In type 1, it’s very possible to get dangerously high ketone levels – just by forgetting to take your insulin injection. There are also other situations like breastfeeding and taking type 2 diabetes medications called SGLT-2 inhibitors26 that in rare situations can result in too high ketone levels.

This will result in feeling sick, nauseous and very weak. It can develop into a life-threatening condition called ketoacidosis. There’s a simple treatment if you suspect this may be happening: eat some carbohydrates right away (e.g. a couple of fruits or a sandwich or a glass of juice). If you have type 1 diabetes take more insulin. Then contact emergency medical services if you do not immediately start feeling better.

The Keto Flu

While ketosis is normally safe, it is common to experience some time-limited side effects.

People transitioning from sugar-burning to fat-burning mode often initially experience side effects. This is referred to as the keto flu, since symptoms are similar to those of the flu: fatigue, nausea, headaches, cramps, etc. There are two main things that one can do to prevent or alleviate these symptoms:

  • Drink water with salt and lemon – alternatively have a daily cup of bouillon.
  • Gradually reduce carbohydrate intake – stopping suddenly results in more temporary symptoms

When starting on a ketogenic diet, you lose water and consequently electrolytes. This is happening since carbs retain water and salts in the body, so when you stop eating carbs your body loses this water. If the keto flu is happening due to too little hydration, it might help to drink a glass of salt water with a little bit of squeezed lemon (for taste).

When carbohydrates are suddenly removed from the diet, the brain can run slightly low on energy before it learns to use ketone bodies for fuel instead of sugar. This means that if you drastically reduce carbs from one day to another, you may get symptoms of such as tiredness, nausea and headaches. Replacing fluids and electrolytes as described above can alleviate the symptoms. Or by instead gradually lowering carb intake over a period of a week or more, the body gets used to burning fat and ketones instead of glucose and there will usually be no symptoms.

If you do not wish to gradually reduce carbs, make sure to get enough fluid and salt (like 1-2 cups of bouillon per day) to minimize symptoms. After a week or so the body is usually adapted to a ketogenic diet.

Q&A, Fine-tuning and Troubleshooting

What’s the difference between low-carb and keto diets?

Keto is a very strict low-carb diet, that also puts even more emphasis on moderating the protein intake, and relying primarily on fat to supply energy needs.

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, if desired, to get even deeper into ketosis.

Keto could be called an extra strict low-carb diet.

Should you aim for high ketone levels to speed up weight loss?

Yes and no. Eating less carbs, less protein and intermittent fasting certainly promotes weight loss, while lowering insulin and raising ketones.

However, adding extra fat to raise ketone levels does not promote weight loss. Neither does supplementing with MCT oil to raise ketone levels, or drinking “exogenous” ketone supplements. These methods actually slow down weight loss, by providing alternative fuel to be used instead of burning body fat.

If you want to lose weight only use these methods – MCT oil or exogenous ketones – when you are hungry, or for performance reasons (unrelated to weight loss).

Learn more: The Benefits of Ketones… Endogenous Ketones

At what time of day should you test ketone levels?

For comparison purposes it’s good to do it about the same time every day. Doing it in the morning before eating makes it most easy to compare the result from day to day.

However, morning values are usually among the lowest in the day, while evening values are higher. So if for some reason you want impressively high values, do it in the evenings instead. Be aware that your ketone levels don’t distinguish between the burning of dietary fat and stored fat.

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

    1. Acetone
    2. Acetoacetate
    3. Beta-hydroxybutyrate

  8. Here’s a recent review article summarizing the science on the topic:

    Skin Pharmacology and Physiology: Nutrition and Acne: Therapeutic Potential of Ketogenic Diets (2012)

  9. One small study has found improvement in memory in people with mild cognitive impairment, using a ketogenic diet:

    There are studies linking high, or even “normal”, non-diabetic blood sugar levels to dementia and Alzheimer’s. Since a ketogenic diet lowers blood glucose it could conceivably cut the risk of developing these diseases. Take a look at this study for instance:

    Crane, Paul K. et al. Glucose Levels and Risk of Dementia. The New England Journal of Medicine, 2013.

  10. 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.

  11. Two studies:

    Euroupean Journal of Neurology 2015: Migraine improvement during short lasting ketogenesis: a proof-of-concept study.

    Vanitallie, TB et al. Treatment of Parkinson disease with diet-induced hyperketonemia: a feasibility study. Neurology, 2005.

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

  14. 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)

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

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

  16. 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.

  17. 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.

  18. 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.

  19. Breath analyzers measure the ketone acetone.

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

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


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

  23. 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).

  24. 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.

  25. The company Prüvit sells drinkable ketones, called KETO//OS. This drink raises blood levels of ketones and may possibly improve physical and mental performance under certain circumstances.

    However, it does not lower insulin or blood sugar, and it does not increase fat burning. Thus it hardly helps with weight loss or type 2 diabetes reversal.

    Also note that they are selling through a multi-level marketing scheme, meaning their affiliates are paid on commission. So take all endorsements with a grain of salt.

    The trick to keeping Keto enjoyable is having lots of delicious recipes. Many people think Keto is a restrictive, boring diet but that's only true if you're not creative. If you want really tasty recipes, there's a great cookbook at: cookingforketosis.com

    For me, keeping keto enjoyable is the most important part. Because if you don't enjoy it, then it's just a matter of time before you'll get sick of it. Been there, done that.

    Kate, drink more water. It helped me with leg cramps and heart palpitations. It was in information or video on this site. Lots of info, in fact. Thanks for Diet Doctor.

    We started the two week free diet plan and I have been feeding the recipes and food intake into the My Fitness Pal - according to their calculations, the total protein intake for day two is 102 grams which seems higher than what is recommended. Other sites I have investigating are recommending around 68-70. The recipe for the Hamburger Patties with creamy tomato sauce had 42 grams by itself, and the Salmon with chili sauce is another 47 grams - Is it supposed to be this high?

    I am in America and I just ordered a free meter from Nova Max (with purchase of two boxes of strips) as Abbott did not have any available free meters according to their website. Go to novacares.com or google "Nova Biomedical meter offer." As others have said in the comments they make their money off the strips- a box of fifty was 19.99 making them .39 per strip. That was listed as a "special" price, and I purchased two boxes to get the meter so my total was 39.98, with free shipping. I have alcohol pads at home and the meter comes with the lancing device and lancets. Also it says there is a savings card that allows cash purchases of the boxes to be $20 at the pharmacy.

    I've been doing a keto diet for exactly 6 months now. I just had my annual blood work done and my total cholesterol increased from 207 last April to 285 just now. My LDL also increased from 130 to 206. My HDL got better: it increased from 50 to 63. Triglycerides have always been good and remain good. I am 5'8" and a female. When I started a keto WOE, I weighed 175lbs and now I am down to 147. I am extremely happy with my weight loss, but don't know what to think about the elevated cholesterol levels. Am I doing something wrong? I really would like to continue a keto lifestyle, but worry about the cholesterol. Do you have any advice?

    That's all great. But... I have come across a recommendation to rise testosterone level by implementing similar diet... but... I guess I will always be hungry, Ive tried at some point before to stay clear of starchy food and carbs overload but Ive lost enormous amount of kg and felt fatigued and near to pass out on a daily basis. It was awful. Im not going to go into what kind of problems I have been facing in details but with regard to hormonal balance... this diet makes sense but Im afraid that will not survive on it.
    By the way what would you say with regard to oats/oatcakes? Parsnip, sweet potato and squashes? Those are my staple foods + brown long rice occasionally/proso millet (and buckwheat rarely). I don't know if by eating zucchini I'd feel better. But I feel there is something wrong with grains definitely though.
    As regards fats, Im on the right track. Only healthy and as much as possible natural... in terms of fats I have no issues. Issues in terms of killing feeling of hunger after eating broccoli with fish = this is ridiculous meal. I dont want to be skinny, but how would you gain weight (muscle mass) by eating green veggies if you are constantly out of energy even to walk not to mention lift something. Thank you so much for any feedback on this matter.

    How do you measure 102 grams of protein iin meals for the day? If i wanted a piece of strak how do i know how much protein is in that piece of strak if it weigjs say 350g of meat? I grt very confused with MFP macros. I have my stats but struggle hoe yo trandlate it into food on my plate and how msny meals to eat in a day. I make up my own lchf and lost 2 stone but stuck for the last 5 months? Started approximstely April 2016. Can you explain how you figured it out?

    My name is Alin, and I have been on the LCHF program for almost 4 months (02.06.2016 - 20.12.2016)
    The reason a begun the diet is because at a routine medical check i did an abdominal ecograph and was told dat i have a non-alcoholic fatty liver (steatosis), and a possible gilbert syndrome (my total bilirubin was 1.77 mg/dl), as well the many health related benefits, described on your site.
    Apart from that, i can say i am generally healthy.

    Before i started the LCHF program:

    Age - 28 years
    Height - 180 cm
    Weight - 80 kg

    TGP(ALT) - 21 U/L
    TGO(AST) - 30 U/L
    Colesterol total - 152 mg/dl
    HDL colesterol - 62 mg/dl
    LDL colesterol - 91 mg/dl
    Triglycerides - 53 mg/dl
    Creatinine serum - 0.93/dl
    Bilirubin total - 1.77 mg/dl
    Glucose - 81 mg/dl

    After LCHF (16.12.2016)

    Weight - 77 kg (3 kg lost in the first week)

    TGP(ALT) - 56 U/L
    TGO(AST) - 43 U/L
    Colesterol total - 240 mg/dl
    HDL colesterol - 81.8 mg/dl
    LDL colesterol - 140.8 mg/dl
    Triglycerides - 87 mg/dl
    Creatinine serum - 1.43 mg/dl
    Bilirubin total - 2.31 mg/dl
    Glucose - 108 mg/dl

    On the diet this values got worse, my face was burning from time to time an got all red.
    Other problems i encountered, but expected, wore constipation and muscle cramps (especially on my calves in the morning), but i managed them as best that i could with an increase intake of salt and fiber (psyllium husks), and water.

    The good thing that i found during the diet is that i felt lighter (on a normal carb diet i always felt bloated, horrible), not hungry, and surprisingly energetic, it felt good (aside from the burning face)

    For the moment i have quit the diet on my doctor advice, and i am now trying to understand where i got it wrong.

    I have been on a very low carb diet for over 5 years. Initially I lost 3 stone - so down to 9 stone. Maintaining this very strict regime, I find that over the last year or two, 1.5 stone has crept back on. What can I do to halt this? I could not eat less carbs!

    Bonjour !
    J'apprécie beaucoup votre site, mais je ne parle pas très bien anglais...
    Existe-t-il en français ?

    I find the recipe quantities to be confusing. For example, on the left side of the recipe, under "Ingredients," the text reads: "1 + 1 serving (dinner + lunch)." But, on the right side of the recipe, under "Instructions," the text reads: "Instructions are for 4 servings. Please modify as needed." So I'm left wondering...did I just make 4 servings, meaning 2 dinners and 2 lunches? Or, did I make 1 serving of 1 dinner, and 1 serving of 1 lunch to eat the next day? I must know so that I can either eat half of what I've made for dinner, and the other half the next day at lunch (assuming I'm hungry while I eat), or, I can eat 1/4 of what I've just made for dinner, 1/4 for lunch, 1/4 for another dinner, and the last 1/4 for lunch again. Please answer when able.

    The moderator needs to give counseling to many participants in this forum. Some have reached dangerously high level values of some health state indicators and should probably be advised to quit and seek medical help immediately.

    Loved the overview, it helped me preparing for my own experiment with Ketogenic diet. I recently blogged about my experience, maybe the article is interesting for a few people considering a Keto diet. http://www.life-sparring.com/blog/2017/03/15/keto-week-one

    I'm on day 6 and I'm gaining half pound a day. Im so disappointed. I'm not a quitter and will keep following this diet for 10 days. Does anybody gain weight on this diet?

    So I started LCHF along with my Type 1 son to help him transition to better blood sugars etc. I have checked my ketones with our blood ketone Meter yesterday and the day before and came up with 5.6 & 6.0. I see most places state nutritional ketosis is up to 3.0. Are these levels of ketones "bad"? How can they be so high when others can barely get to a 1.0. I have been quite LC this week with mostly getting carbs from veggies, my creamer, and some strawberries etc. If this is bad, what do I do to fix it without knocking myself out of ketosis. Although I am doing LC to support my son I would like to see the weight losss and physiological benefits as well.
    Final question would having 6.0 ketones cause me to be dizzy, light headed and generally weak even with a BG of 82? This morning I woke up like this and was convinced my BG was low but it proved otherwise.

    Oh I am doing IF well and had been fasting from 6pm last night. Checked ketones at like 3-4am because I was up Checking on my son.
