Introduction
The keto diet, also known as ketogenic diet, is a dietary regimen that primarily relies on fats while drastically reducing carbohydrate intake. The goal of this diet is to shift the body into a state of ketosis, where fats are used as the main source of energy instead of carbohydrates.
Concept of the Keto Diet
The keto diet involves consuming large amounts of fats, a moderate amount of protein, and very low amounts of carbohydrates. By significantly reducing carbohydrate intake, blood glucose levels drop, prompting the body to seek an alternative energy source. In this state, the liver begins converting fats into ketones, which the body can use as an energy source.
