Prior to surgery, we do not require patients to go on any specific or special diet to lose weight. However, early on in the process (in fact, right after I have my consultation with a patient) we begin working with them to help them to change their lifestyle and start eating healthier foods and to start exercising. In general, we expect to see patients lose some degree of weight prior to having surgery. If a patient continues to gain weight or gains a tremendous amount of weight prior to having surgery, that really tells us that they’re probably mentally not prepared and not ready to have surgery at that time. We’ll hold off until we are sure that that patient is ready to have surgery.
