What is Keto Diet?

A keto or ketogenic diet is a very low-carb diet, which can help you burn fat more effectively. Many people have already experienced its many proven benefits for weight loss, health and performance.
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 is the keto diet?

The Keto diet emphasizes weight loss through fat-burning. The goal is to quickly lose weight and ultimately feel fuller with fewer cravings, while boosting your mood, mental focus and energy. According to Keto proponents, by slashing the carbs you consume and instead filling up on fats, you safely enter a state of ketosis. That’s when the body breaks down both dietary and stored body fat into substances called ketones. Your fat-burning system now relies mainly on fat – instead of sugar – for energy. While similar in some ways to familiar low-carb diets, the Keto diet’s extreme carb restrictions – about 20 net carbs a day or less, depending on the version – and the deliberate shift into ketosis are what set this increasingly popular diet apart.

The Keto diet has its roots in the decades-old therapeutic ketogenic diet. Clinically, the ketogenic diet is used in neurologic medicine, most notably to reduce hard-to-control seizures in children. Studies also suggest possible benefits in other brain conditions such as Parkinson’s and Alzheimer’s diseases.

The “keto” in a ketogenic diet comes from the fact that it allows the body to produce small fuel molecules called “ketones”. This is an alternative fuel source 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).

The liver produces ketones from fat. These ketones then serve as a fuel source throughout the body, especially for 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.

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.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. This may help keep you alert and focused.

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 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.
