Constant hunger is the biggest issue when you try to lose weight. The keto diet helps avoid this problem because reducing carb consumption and increasing fat intake promote satiety, making it easier for people to adhere to the diet. In a study, obese test subjects lost double the amount of weight within 24 weeks going on a low-carb diet (20.7 lbs) compared to the group on a low-fat diet (10.5 lbs).
