Dieting is the practice of ingesting food in a regulated fashion to achieve a particular objective. In many cases the goal is weight loss, but some athletes aspire to gain weight (usually in the form of muscle) and diets can also be used to maintain a stable body weight.

If you have ever been to a tropical country, you have probably experienced diarrhea: frequent and uncontrolled evacuation of liquid stool caused by bacteria in local water, milk or food. Diarrhea can also be caused at home by excesses in diet (a diet that is too rich) or an allergic reaction to certain foods or medication or even by stress.

Sally Krawczyk tried everything from liquid diets to low-carb regimens to Weight Watchers to lose weight, but none were successful. But she says she's finally discovered a successful way to lose weight. On the advice of her doctor she's been taking an antiseizure medication and two antidepressants, and has lost 135 pounds in 18 months.
