Thank you for your excellent question. Immediately after surgery many patients experience a blunted appetite due to anesthesia and failure of their stomach and intestines to work normally. Once both of these effects pass, appetite resumes and the body starts to demand a large intake of calories to help heal the skin and other tissues operated on by the tummy tuck. Just as when you are working out the key is to maintain a healthy diet of lean meats, fish, fruits, and vegetables to give your body the needed building blocks for repair. Hope this helps.
