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.
If the loss of appetite is due to the use of prescription drugs and medications than this condition is most likely temporary and reversible. Other conditions can be far more serious and need to be evaluated by a health-care professional.
These include conditions such as depression, dementia, anorexia, metabolic problems, liver disease, kidney failure, heart disease, bacterial infections, diarrhea and the effects of underlying cancer, chemotherapy, pain killers and antibiotics.
Any persisting lack of appetite is a serious condition and needs to be addressed and the causes identified to restore healthy eating habits and the consumption of nutritious foods.
