This will also help if you are constipated. Whether you are eating too little or too much, set regular meal times. Eat three or four small meals through the day, rather than one or two large ones. Never snack between meals. Snacks, which are usually full of calories, are just about the worst thing if you have a weight problem.
Exercise is the other important factor in appetite control.
Exercise will improve a poor appetite. It will also help burn off excess calories if you are overweight. Try to do the equivalent of walking at least a mile a day. You will often find senior walking groups at shopping malls before the stores open. Contact your local parks and recreation department or your local senior center to find out if there is a group near you.
