Decreased appetite

Lack of appetite, or decreased hunger, is one of the most troublesome nutrition problems you can experience. Although it is a common problem, its cause is unknown. There are some medicines that might stimulate your appetite. Ask your doctor if such medicines would help you.

Solutions:

Eat smaller meals and snacks more frequently. Eating six or even or eight times a day might be more easily tolerated than eating the same amount of food in three meals.
Talk to your doctor. Sometimes, poor appetite is due to depression, which can be treated. Your appetite is likely to improve after depression is treated.
Avoid non-nutritious beverages such as black coffee and tea.
Try to eat more protein and fat, and less simple sugars.
Walk or participate in light activity to stimulate your appetite
