A low-carb diet for beginners
Studies show that low-carb diets result in weight loss and improved health markers, and just about everyone knows someone who has successfully tried it.1 There’s not even any need to count calories or use special products. So why is it still controversial?

1. Introduction to low carb
A low-carb diet means that you eat fewer carbohydrates and a higher proportion of fat. This can also be called a low-carb, high-fat diet (LCHF) or a keto diet.
For decades we’ve been told that fat is detrimental to our health. Meanwhile low-fat “diet” products, often full of sugar, have flooded supermarket shelves. This has been a major mistake, that coincided with the start of the obesity epidemic.
Studies now show that there’s no reason to fear natural fats. Fat is your friend (here’s why). On a low-carb diet, you instead minimize your intake of sugar and starches. You can eat other delicious foods until you are satisfied – and still lose weight.
How does it work? When you avoid sugar and starches, your blood sugar stabilizes and the levels of the fat-storing hormone insulin drop. This increases fat burning and makes you feel more satiated, reducing food intake and causing weight loss.2
- Eat: Meat, fish, eggs, vegetables growing above ground and natural fats (like butter).
- Avoid: Sugar and starchy foods (like bread, pasta, rice, beans and potatoes).
Eat when you’re hungry, until you’re satisfied. It’s that simple. You do not need to count calories or weigh your food. And just forget about industrially produced low-fat products.
Below are examples of what you could eat, alternatively check out our 500+ low-carb recipes.
Most people can safely start any kind of low-carb diet. But in these three situations you may need some preparation or adaptation:

If you’re not in any of these groups, you’re good to go. Great!

Try to avoid
Here’s what you should not eat on low carb – foods full of sugar and starch. These foods are much higher in carbs.
The numbers are grams of digestible carbs per 100 grams (3.5 ounces), unless otherwise noted.
What to drink
What drinks are low carb? Water is perfect, and so is coffee or tea. Preferably use no sweeteners. A modest amount of milk or cream is OK in coffee or tea (but beware of caffe latte and other specialty coffees!).

How low is low carb?
The fewer carbohydrates you eat, the more powerful the effects on weight and blood sugar will be. We recommend initially following the dietary advice fairly strictly. When you’re happy with your weight and health, you may carefully try eating more carbs (if you want to).
Here are three examples of what a low-carb meal can look like, depending on how many carbs you plan to eat per day:
A strict low-carb diet is often called a ketogenic (or “keto”) diet.

5. Potential side effects on low carb
If you stop eating sugar and starch cold turkey (recommended) you may experience some side effects as your body adjusts. For most people these side effects tend to be mild and last a just few days. There are also ways to minimize them.
Another option is to decrease the intake of carbohydrates slowly, over a few weeks, to minimize side effects. But the “Nike way” (Just Do It) is probably the best choice for most people. Removing most sugar and starch often results in several pounds lost on the scale within a few days. This may be mostly fluids, but it’s great for motivation.
Here are side effects that may occur when you suddenly start a strict low-carb diet.
By far the most common side effect is called the induction flu. It’s what makes some people feel really poorly 2-3 days after starting low carb.
Here are the common symptoms:
- Light nausea
These side effects rapidly subside as your body adapts and your fat burning increases. Within a week, they are usually gone.
The reason for this is that carbohydrate-rich foods may increase water retention in your body. When you stop eating high-carb foods you’ll lose excess water through your kidneys. This can result in dehydration and a lack of salt during the first week, before the body has adapted, resulting in the symptoms above.
You can minimize the induction flu by drinking more fluids and by temporarily increasing your salt intake. A good option is to drink a cup of bouillon/broth one or two times a day. This usually keeps the induction flu minor or even non-existant.
Alternatively, drink a few extra glasses of water and put more salt on your food.
Other common issues on low carb
Beyond the induction flu, there are five more relatively common side effects. Many of them can also be mostly avoided by getting enough fluid and salt.5
There are also more things you can do to minimize any problems, click to read more if you’ve experienced one of these issues:
Less common issues
These are less commonly noticed issues, that generally only affect a minority of people:
Beyond the usually minor and transient side effects that may occur (see above) there are tons of myths and fears that simply don’t hold up to closer scrutiny. For example, your brain is supposed to stop working unless you eat carbs. We’ll, that’s simply wrong.
There are many more unfounded fears about low carb, that are mostly based on myths and misunderstandings. Read all about them on our low-carb myths page, or choose a specific topic below:

Scientific studies now prove that compared to other diets, low carb is more effective.
Here are two of the top studies showing more weight loss and improvements in health markers on low carb:
- New England Journal of Medicine 2008: Weight loss with a low-carbohydrate, mediterranean, or low-fat diet
- Annals of Internal Medicine 2014: Effects of Low-Carbohydrate and Low-Fat Diets: A Randomized Trial
Similar results have been found in meta-analyses of all studies, for example this recent analysis:

Does this sound too good to be true? Many people think so initially, and then they experience it for themselves.
Our weight is hormonally regulated. Eating fewer carbohydrates lowers blood glucose, lowering the fat-storing hormone insulin. This often makes it way easier to access and burn excess body fat, without hunger or calorie counting.
