Loss of appetite is a condition when foods are not appealing or a medical condition is present preventing you from eating normally. This is different then trying to lose weight and minimum amounts of food are eaten to accomplish a weight loss over a period of time.

Even on a low-calorie weight loss program, the foods allowed should always be enough to keep you from experiencing hunger and you should maintain a healthy appetite. Often supplements are recommended to ensure that levels of vitamins and minerals are provided when nutrients are lacking to prevent side effects and imbalances.
