The U.S. Weight Loss & Diet Control Market (16th Edition)

The U.S. Weight Loss & Diet Control Market (16th Edition)

The U.S. weight loss market reached a record $78 billion in 2019, but suffered a 21% decline in value during 2020 due to the Covid-19 pandemic and recession. However, there were bright spots. Commercial chains held up well, as did the meal replacements market, frozen diet entrees, and multi-level marketing channels. Health clubs and most medical weight loss programs were hit the hardest, with contractions of 37% and 27%, respectively. Weight loss providers had to pivot to virtual client meetings and drop shipping of products. Technology became more important, as Zoom meetings, apps and streaming services soared in usage. Due to pend-up demand and consumer weight gain in 2020, most providers are looking for a strong rebound in 2021, as Americans are vaccinated and businesses reopen.

Do-it-yourself plans still abound as consumers use free diet & fitness apps. Many untapped niches still exist. This is a completely revised and updated analysis of Marketdata’s best-selling biennial study about the U.S. weight loss market. This is the most comprehensive investigation of the U.S. weight loss market published by anyone worldwide.
