Anything you can do that helps you with portion control, will help you lose weight. Cottage cheese and Greek yogurt and hot dog and canned tuna diets work, because it’s easy to limit your calories to 1000 or 1500 a day. The calorie and carohydrate count is on the container. It’s also helpful to buy conveniently sized containers, so you don’t have to weigh or measure. Just eat the whole thing. One food, all protein diets are the most effective. Eat just hot dogs for a day or two. Then eat just cottage cheese for a day or two. Then eat just tuna for a day or two. Most patients lose 4-5 pounds every week on one food, all protein diets.
