Full carbohydrate, low calorie, low fat diets don’t work well, because they facilitate too much fat storage. The more carbohydrate you eat, the easier it is for your body to store fat. You are also ravenously hungry. Paleo diets don’t work well, because it’s way too easy to eat way too many calories of meat, fruit and nuts. You probably won’t lose weight. Atkins doesn’t work well, because it’s way too easy for most people to eat way too many calories of dead animal and fat for weight loss. Alternate day fasting diets generally don’t work well, because you can’t eat as much as you want on your “off day”, and expect to lose weight fast enough to stay on the diet.
