Carb Cycling
By now we know that carbs are a major factor behind weight gain (thanks, Dr. Atkins), but who wants to live in a world without spaghetti? Carb Cyling is the ideal choice for those looking for some flexibility in their low-carb diet, and, like intermittent fasting, all it requires you to do is alternate days. Vanderpump Rules star Scheana Shay recently told Us Weekly that the method has helped flatten her stomach, and all you really need is a week or two to start seeing results.
