It Depends: Why are you against exercising? What about just trying to do some walking? You need to take in/consume the same amount of calories in one day as you are utilizing/burning in order to maintain a constant weight. Eating a balanced diet is best. Maybe, you could find a nutritionist or dietitian to help you learn about healthy foods and a balanced diet? Try and focus on health and not weight.
