The Science Behind The Popular Keto Diet
This diet places extreme restriction on carbohydrates and promotes high fat intake. Protein is kept at moderate consumption. With the extreme restriction on carbs, some would classify ketogenic diet as a form of carb-restrictive diets.
The goal of the dietary requirements is to promote a state called ketosis. This is when the body uses stored fats as source of energy, instead of using readily available glucose (from rapidly digested carbs). Fats are metabolized to produce ketone bodies.
