Disease and medications can affect these senses too. Poor teeth or dentures may ruin the taste of food or make chewing difficult. Shopping and cooking may be painful or difficult because of arthritis, walking problems, or lack of transportation. Cooking for one usually isn't much fun. Loneliness and depression may add to disinterest and loss of appetite.
Limited funds can present problems at the grocery store.
Increasing the amount of exercise might be a good way to start. Mild exercise, such as walking, not only gets the appetite going, it helps maintain muscle strength and control blood sugar levels. Pay attention to portions and food groups and increase them where needed. Go out with a friend or eat at a community-dining center on certain days or at certain meals to add variety and companionship. Try new recipes and foods.
