The most popular diet of the year is none other than the incomparable Jillian Michaels. It’s not entirely surprising when you consider she’s been one of the most consistent players on our list since 2021, with her online brand, detox product, and earliest workout DVD ranking each year. In fact, the latter two were both on last year’s top ten list. We expect to see Curves, ranking for the first time since 2021, as the Biggest Loser trainer just announced a new partnership with Curves.
What is most surprising is how Jillian Michaels knocked the giant that is Weight Watchers out of the number one position. That’s only been done once before, by 17 Day Diet in 2021. Even that year Weight Watchers held on to number two, but this year they slipped in to the fifth most popular spot.
And 17 Day Diet grabbed ranking number four, hardly losing any ground since its overwhelmingly popular release in late 2021. Its position on our annual Most Popular lists, ahead of Weight Watchers once again, will no doubt help with the release of 17 Day Diet: Breakthrough Edition on the 31st.
The only constant between last year’s list and this – Medifast. They’ve got number 3 on lock, with the meal delivery diet staying strong in the top ten since 2021.
Another staple of our list fell pretty hard this year, with hCG falling down to number 14. No, the supplement boom isn’t over, as its disappearance only made room for brands like Skinny Fiber (a shocking number 2) and Plexus Slim (at number 6) to move on up the list. Dr. Oz-endorsed Raspberry Ketones (17) and Green Coffee Bean Extract (20) were other weight-loss-by-pill categories that did especially well this year.
