The total U.S. weight loss market is estimated to have grown to a historic peak of $90 billion in 2023, boosted by soaring sales of the popular prescription GLP-1 weight loss drugs. This is a major paradigm shift toward medical programs, and a major challenge for competing commercial diet companies, which lost $1+ billion in revenues since 2022.
GLP-1 drugs are a game changer in terms of the number of medications now on the market, plus others to come in the next several years. They have affected dieter behavior and how commercial diet companies operate. Nearly all non-medical segments of the market have felt the pain of declining sales, and 26,500 weight loss coaches have lost their jobs. However, more physicians are adding weight loss to their practices, bariatric surgeries are hitting new highs, and caseloads/revenues at medical weight loss franchises and at bariatricians are growing.
