Heart health experts lay out exactly why you should be wary about the diet that encourages high-fat foods.
A keto diet stresses high intake of animal and vegetable fats (avocado), and proteins, in place of carbohydrates. By reducing the availability of glucose for the body to metabolize, a back-up system called ketosis is initiated in which the liver uses fat to produce energy. Short-term weight loss results are mixed; long-term effects, including the consequences of added stress on the liver and kidneys, are unknown.
