There's a right way and a wrong way to lose body weight. Most of the wrong ways involve rapid weight loss. Many quick-loss methods are banned by high school sports organization and the NCAA. Others are simply ineffective, and they make your goals harder to reach.

Method		Result
Yo-Yo Dieting	Cycles of starving before competition and eating after, usually bingeing.	Your body will store more fat, and it will be more difficult to lose weight. It also places a great amount of stress on your body.
Fasting	Constant starving or consuming too few calories.	Your body loses muscle mass first, not fat. In addition, your body reacts to starvation by burning fewer calories, making it even harder to lose weight.
Diet Pills	These pills suppress appetite and force a temporarily increase in metabolism.	Many of these pills contain products that increase your heart rate and blood pressure to dangerous levels. They often dehydrate you as well.
Dehydration	Avoiding fluids in an effort to lose water weight.	Dehydration decreases muscle strength and endurance, reduces blood flow in your body, and makes it difficult for your body to maintain its temperature.
Forced Dehydration	Taking diuretics (water pills), using a steam room/sauna, exercising in plastic suits.	Diuretics can impair the function of your heart and kidneys. Rapid loss of water can lead to heat stroke, heart failure, and death.
