Since excess calories drive weight gain and fat accumulation in the liver, the key to reversing fatty liver and type 2 diabetes is a low-calorie diet. All calories, when they are overconsumed, contribute to excess fat in the body, whether they come from fat, protein, or carbs. For this reason, the best diet to reverse fatty liver is a hypocaloric diet. Professor Roy Taylor recommends a hypocaloric diet of no more than 800 calories per day during the initial phase of rapid weight loss. ~ Didem
