11.The Raw Food Diet
Most of us could stand to eat more fruits, vegetables, and nuts. But this diet lets you eat only plant foods that haven’t been heated to more than 116 F. So food safety can be an issue. People who eat exclusively raw end up with low levels of important nutrients like vitamin B-12. It’s also hard to get the calories your body needs. You may lose weight at first. But you’re likely to feel less than your best.
12.The Cookie Diet
Eat cookies and lose weight. It sounds fun, but don’t bet on it as a slim-down strategy. Under this diet, you’d eat nine 60-calorie cookies and one 500- to 700-calorie meal a day. It may help you slim down in the short term. But chances are you’ll get too few vitamins, minerals, and calories. That can sap your energy, making it hard to exercise and get through your day.
