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.
As ketogenic diets require 50 to 70 percent of your calories come from beneficial fats, your body learns to burn fat for energy. During this state, the body produces ketones, made from fats processed in the liver.
