Dublin, March 10, 2026 (GLOBE NEWSWIRE) -- The "The U.S. Weight Loss Market: Status Report & 2026 Forecast" report from Marketdata LLC has been added to ResearchAndMarkets.com's offering.
This Marketdata report presents a wrap-up of 2025 performance for the U.S. weight loss market during the obesity drugs market explosion and a forecast for 2026. The value of the total market is estimated to have grown to a historic peak of $135 billion in 2025, boosted by soaring sales of the popular prescription GLP-1 weight loss drugs. This is a paradigm shift to medical programs, and a major challenge for competing commercial diet companies.
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 26,000+ weight loss coaches have lost their jobs. However, more physicians are adding weight loss to their practices, the number of bariatricians are hitting new highs, and the number of medical weight loss centers has grown.
The report includes in-depth analyses of: 2024-2025 market/revenue performance, recent competitor and market developments, current dieter trends and top diet plans, and diet company advertising and marketing spending.
