The HCG Diet[7]. This diet combines injections or supplements of HCG (human chorionic gonaotropin) with a severely restricted calorie intake.
- The calorie restriction alone (only 500 to 800 calories per day) is enough to promote weight loss in most people; it is significantly under the recommended daily calorie allowance, even for people attempting to lose weight.
- HCG is not monitored by the FDA, and can have unpleasant side effects in many people.
- Those who follow this diet typically gain the weight back immediately after stopping it.
