Eating can be a challenge. Some people with AD want to eat all the time, while others have to be encouraged to maintain a good diet. Try to ensure a quiet, calm atmosphere for eating. Limiting noise and other distractions may help the person focus on the meal.
Also, provide a limited number of choices of food and serve small portions. You may want to offer several small meals throughout the day in place of three larger ones.
