The keto diet, short for ketogenic diet, is a low-carb, high-fat diet that has gained popularity in recent years for its potential to aid in weight loss and improve overall health. The diet works by putting the body into a state of ketosis, where it burns fat for energy instead of carbohydrates. In this article, we will delve into the basics of the keto diet, its benefits, and how it can be used for weight loss.
What is Ketosis?
Ketosis is a metabolic state in which the body burns fat for energy instead of carbohydrates. When the body's carbohydrate stores are depleted, it begins to break down fat into molecules called ketones, which can be used as energy. This process is called ketogenesis. Ketosis is a natural state that occurs when the body is not receiving enough carbohydrates to use for energy, and it is not the same as diabetic ketoacidosis, a serious condition that can occur in people with diabetes.
How Does the Keto Diet Work?
The keto diet works by drastically reducing the intake of carbohydrates and increasing the intake of fat. This forces the body to switch from using glucose (sugar) as its primary source of energy to using ketones, which are produced by the liver from fat breakdown. The diet typically consists of 70-80% fat, 15-20% protein, and 5-10% carbohydrates. By limiting carbohydrate intake, the body is able to enter a state of ketosis, where it burns fat for energy.
