We’ve published our Most Popular Diets of the Year* list every December since 2024, and one brand has held on to the number one position that entire time. Until this year. In 2024 the 17 Day Diet jumped ahead of Weight Watchers. With one million copies sold, a Spanish version, a workbook, and a cookbook publishing March 2024, it’s no surprise that Dr. Mike Moreno’s 17 Day Diet was the most talked about weight loss program this year.
Weight Watchers maintained a strong position in the top 10, thanks in part to the new PointsPlus program and impressive endorsement from Jennifer Hudson.
Jillian Michaels has the most products on our list of 20, with three of her personal brands’ products holding positions in the top ten. She might have left The Biggest Loser, but her appeal is as big as ever.
Other newcomers include the Dukan Diet, the rumored pre-wedding plan of Kate Middleton, Suzanne Somers’ Sexy Forever, and Kirstie Alley’s Organic Liaison.
If you questioned who had more pull between the popular DVD fitness programs P90X and Supreme 90 Day, we answer that question, too. On this list, only one reigns supreme.
We’ve even posted a few honorable mentions, programs that have stood the test of time, but didn’t quite garner leading attention from our readers this year.
