Adherence

Mandatory structured lifestyle modification programs prior to metabolic surgery do not improve post-operative outcomes and may cause harm by delaying access to surgery.

If you are being told you must complete a mandatory weight loss program before surgery, understand that this is likely a bureaucratic or insurance barrier, not a medical necessity. The evidence shows these programs do not improve surgical outcomes and may delay life-saving treatment. Seek a second opinion from a surgeon who follows modern guidelines that do not mandate pre-surgical weight loss.
