Reduce the caloric intake and rev up the exercise. I got some barbells at Wal-Mart and started a weight training program at home. Lots of exercise books out there that helped me get started. If you can't walk, no problem, use ankle weights, sit in a chair and do leg lifts. Do bicep and tricep curls. You can lie on the bed and do abdominal crunches. If you can walk add that in with the weight lifting. Muscles burn a lot of calories. I only lift 12 pounds, I started with 1 pound weights and have worked up. I can see the difference and feel the difference. I do not eat junk food, sweets, anything with white flour and beef. I eat 6 small meals a day of 200-250 calories, most of which is protein, good carbs and a little fat. This keeps the blood sugar level, no sugar spikes and I never feel hungry.
