A keto or ketogenic diet is a low-carb, moderate protein, higher-fat diet that can help burn fat more effectively and has many benefits for weight loss, health, and performance as shown in over 50 studies. On a keto diet, the body enters a state of ketosis where it burns fat instead of carbohydrates for energy. To achieve ketosis, the diet must restrict carbohydrate intake to under 50g of net carbs per day, ideally below 20g. The diet focuses on foods low in net carbs like meat, fish, eggs, cheese, and non-starchy vegetables.

1. A ketogenic diet for beginners
A keto or ketogenic diet is a low-carb, moderate protein, higher-fat diet that can help you burn
fat more effectively. It has many benefits for weight loss, health, and performance, as shown in
over 50 studies.1 That’s why it’s recommended by so many doctors.2
A keto diet can be especially useful for losing excess body fat without hunger and for improving
type 2 diabetes.34
Here, you’ll learn how to eat a keto diet based on real foods. Get started with our visual guides,
recipes, meal plans, and simple 2-week Get Started program. It’s everything you need to
succeed on keto.
1. What is a keto diet?
The keto diet is a very low-carb and higher-fat diet. It’s similar in many ways to other
low-carb diets.
While you eat far fewer carbohydrates on a keto diet, you maintain moderate levels of
protein intake and may increase your intake of fat. The reduction in carb intake puts your
body in a metabolic state called ketosis, where fat, from your diet and from your body, is
burned for energy.

What “keto” means
The “keto” in a ketogenic diet comes from the fact that it allows the body to produce
small fuel molecules called “ketones.”5 This is an alternative fuel source for the body,
used when blood sugar (glucose) is in short supply.

2. When you eat very few carbs or very few calories, the liver produces ketones from fat.
These ketones then serve as a fuel source throughout the body, especially for the brain.6
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.7
On a ​ketogenic​ diet, your entire body switches its fuel supply to run mostly on fat,
burning fat 24-7. When insulin levels become very low, fat burning can increase
dramatically. It becomes easier to access your fat stores to burn them off.8 This is great
if you’re trying to lose weight, but there can also be other, less obvious benefits, such as
less hunger and a steady supply of energy (without the sugar peaks and valleys we can
get from high carb meals). This may help keep you alert and focused.9
When the body produces ketones, it enters a metabolic state called ketosis. The fastest
way to get there is by fasting – not eating anything – but nobody can consistently fast
forever.10
A keto diet, on the other hand, also results in ketosis and can be eaten indefinitely. It has
many of the benefits of fasting – including weight loss – without having to fast long-term

Here are typical foods to enjoy on a ketogenic diet. The numbers are net carbs, i.e.

Vegetables that grow above ground

There are controversies and myths about a keto diet, but for most people it appears to be
very safe.12 However, three groups often require special consideration:
Do you take medication for diabetes, e.g. insulin? More

6. Do you take medication for high blood pressure? More
Do you breastfeed? More

Disclaimer: While the ketogenic diet has many proven benefits, it’s still controversial.
The main potential danger regards medications, e.g. for diabetes, where doses may need
to be adapted (see above). Discuss any changes in medication and relevant lifestyle
changes with your doctor. Full disclaimer

7. Try to avoid
Here’s what you should avoid on a keto diet – foods containing a lot of carbs, both the
sugary and the starchy kind. This includes starchy foods like bread, pasta, rice, and
potatoes. These foods are very high in carbs.
Foods to avoid on a ketogenic diet: bread, pasta, rice, potatoes, fruit, beer, soda, juice,
candy
The numbers are grams of net carbs per 100 grams, unless otherwise noted.16
Also avoid ultra-processed foods and instead follow our whole foods keto diet advice.
You should also avoid low-fat diet products. A keto diet should be moderately high in
protein and will probably be higher in fat, since fat provides the energy that you are no
longer getting from carbohydrate. Low-fat products usually provide too many carbs and
not enough fuel from protein and fat.17
What to drink
Keto drinks: water, coffee, tea, dry wine
What can you drink on a ketogenic diet? Water is the perfect drink, and coffee or tea are
fine too. Ideally, use no sweeteners, especially sugar.18 A splash of milk or cream in your
coffee or tea is OK, but beware that the carbs can add up if you drink multiple cups in a
day (and definitely avoid caffe lattes!). The occasional glass of wine is fine too.
