On a liquid diet the items that are allowed are usually vegetable juices with vitamins added and sometimes protein shakes. Most of the liquid diets that are approved for rapid weight loss are liquids that were developed in hospitals to help give patients that couldn't eat the nutrition that they needed while they were recovering. Another one of the most common ideas is the severely restricted calorie diet. There are several diets where you can only have 800 calories a day. Severely restricting calories can keep your body from shutting down the way it would if you stopped eating all together and will prevent your body from storing fat instead of burning it while still boosting your metabolism and helping you lose weight.

Rapid weight loss can be very risky, so if you are only slightly overweight or don't have that much weight to lose you shouldn't go on this type of diet. If you are just looking for rapid weight loss ideas so that you can fit into that special outfit for a special occasion that's a different story. There are lots of commercially available juice fasts and other ideas that can help you drop up to twenty pounds of water weight and bloat in the span of a couple of weeks. Those products are not the ideal way for you to lose weight but if you don't use them all the time and are only using them to get into that special dress or to fit into that old tux for an event then you will probably not suffer any long term damage. Just make sure that during the time you're on the juice fast or other rapid weight loss program you take it easy. Your body will be adjusting to the sudden lack of calories and you may get dizzy a lot or you might not have the energy that you had before you went on the program. If you're working out regularly you might want to switch to an easier workout program for the time that you're on the weight loss program. When you go back to eating normally you will probably gain back all that water weight so be prepared. If you really want to lose weight you need to diet and exercise, a rapid weight loss program is only a temporary solution.
