Yes. Many insurance companies require patients to be on a weight loss program before qualifying for surgery.

Many bariatric surgeons put their patients on a special pre-operative diet, usually 2 or 3 weeks just before surgery. The reason for the pre-operative diet is to shrink the liver and reduce fat in the abdomen. This helps during the procedure and makes it safer.

Some insurance companies require a physician-monitored diet three to six months prior to surgery as part of their coverage requirement. These diets are very different from the short-term diets and usually are more about food education and showing a willingness to complete appointments and to learn.
