18Shake claimed the number one spot this year, jumping from it’s #13 position in 2023. Not only is this just the fourth brand to hold the coveted spot but it’s the first time ever for a supplement product. Supplements were big all around for 2023, with Skinny Fiber, Plexus Slim and Omnitrition drops rounding out the top 5 , alongside The 17 Day Diet still holding strong at the top since its successful release in late 2023.

Perhaps even more surprising is who didn’t make claim a top spot this year. This is the first time since we started the list in 2023 that Jillian Michaels does not make an appearance anywhere.  It’s also the first time Weight Watchers has fallen out of the top 5, now coming in at #10, but with the recent announcement that Oprah will be their new spokesperson in 2023, we foresee them making a comeback next year. Nutrisystem also took a tumble, dropping from #4 last year, all the way down to #24,  just barely making the list.

Our list also shows that restrictive “fad diets” are making a comeback with the appearance of the Tapeworm Diet and Cabbage Soup Diet at #12 and #14 respectively, although we sincerely hope you read our reviews thoroughly before trying.
