A keto diet is a high-fat, adequate protein, a low-carb diet which causes the change in body’s primary source of fuel from glucose to ketones, considered as a ketogenic diet.
Ketones are by-products of the incomplete breakdown of free fatty acids in the liver. When they accumulate in the bloodstream causes a metabolic state called as ketosis.
How it works– when ketosis is developed simultaneously there is a decrease in glucose utilization and production, along with this protein breakdown is also decreased making ketogenic diet beneficial for protein sparing action. Hence keto diet helps in losing fat but also maintain the body’s lean mass.
