Keto diets mainly involve the drastic reduction of one’s carbohydrate intake, and replacing it with fats. Reducing the carb content like this puts the body in a metabolic state known as ketosis.
In this state, your body is able to efficiently burn fat for energy. It can also convert fats in the liver into ketones. This helps supply energy for the brain.
When following a keto diet, some people may find it difficult to work out the right foods to eat and when to eat them. Meal plans can help people get used to the diet or stick with it.
