You can lose a lot of weight by just exercising more.
Even sustained exercise (which is usually not possible for those with Severe Obesity) alone does not produce a sufficient calorie deficit to result in significant weight loss. Significant weight loss can only occur with a significant reduction in calorie intake. However, exercise is very important in helping to keep the weight off once you have lost it after bariatric surgery.
