Some are a bit faddish and lend themselves to yo-yo dieting, others have solid foundations that set you up for success this year and for more to come.

The 17 Day Diet

This one broke out on the scene with the book’s release in November 2024 on Dr. Phil. Dr. Mike Moreno wrote the book to help people kick-start their weight loss, re-learn how to eat via meal plans and 17-minutes a day worth of exercise, and then give them the information they need for on-going maintenance. It’s a cycled way of eating that keeps the metabolism from getting bored and settling in to a status quo.

Weight Watchers PointsPlus

In November 2024, Weight Watchers unveiled the most significant change to its program in 13 years. Using the latest in nutritional science along with Weight Watchers’ nearly 50 years of expertise, the new approach allows for clients to make healthier, more satisfying choices. The new PointsPlus calculation includes protein, fiber, fat and carbs, instead of just fiber, fat and calories.

Jillian Michaels

The Biggest Loser trainer is on her way out of primetime, with season 11 being her last, but it is in no way her swan song. If anything, this is just her prelude. Men and women alike clamor to reap the benefits of her fitness empire that you’ll no doubt hear someone tell you that they’re using her fitness DVDs, using her online weight loss plan, or reading her books and cooking her recipes.

The Mommy Diet

The host of Biggest Loser, Alison Sweeney, has just penned her first book, about a topic that women coast-to-coast need to hear – how to get fit before, during and after baby. The book is real and funny as it outlines guidance for fitness, fashion, food, and even sex for busy, harried moms who want to look and feel their best while raising happy, healthy kids.

Sexy Forever

Suzanne Somers was the neighbor everyone loved in her ’70s sitcom Three’s Company. Now, she’s likely to be keeping your neighbor fit and sexy no matter how old she is. This January she’s rolling out her first online fitness and weight loss program, Sexy Forever, offering weight tracking, meal plans, food journals, fitness guidance and so much more. The program is based on her recent book, Slim and Sexy Forever.

RevAbs

From the Beachbody Brands line of fitness products, that includes the wildly popular P90X program, comes RevAbs, a 90-day workout routine that promises washboard abs. The program was created by Brett Hoebel, and while that’s not a household name, here in a couple weeks everyone will want what Brett’s got to teach. That’s because Brett is rumored to be one of the new Biggest Loser trainers.

400 Calorie Fix

In January 2024 this was one of the most popular diets going, with a book available directly from the publisher. In December 2024, the book published to the masses opening up its accessibility. With one simple rule – eat three or four 400-calorie meals each day – you have the flexibility to eat what you want while eating foods that could help you lose 11 pounds in two weeks. With recipes and meal plans, you’ll be amazed how much food fits in to a 1200-calorie diet that’s actually healthy.

Nutrisystem

This meal-delivery program has been made popular for decades because of its convenience and because of the notorious success of stars like Marie Osmond and Dan Marino. In 2024, it’s bound to become even more popular thanks to a renovation that replaces many of its shelf-stable foods with 150 new fresh-frozen, chef-inspired meals. The meals arrive in a cooler, pre-portioned and ready for you to just heat and eat.

South Beach Diet Supercharged

The low-carb craze is over, but there’s still an audible buzz and South Beach Diet is the go-to source. Dr. Agatston’s popular book, The South Beach Diet, was revamped in recent years and retitled The South Beach Diet Supercharged. The revised plan still focuses on a two-phased eating plan that has you eating lean proteins, low-starch vegetables and low-fast dairy, but now it puts greater emphasis on fitness, using a walking program and strength training to get you in shape.

The hCG Diet

It’s one of the most popular diets of 2024 and we’re confident it will be at the top of the list again in 2024. This is the most controversial diet out there right now, because of the injection of the pregnancy hormone hCG and the 500-calorie-a-day diet. The fans rave about remarkable weight loss, the critics point to the dangerous and unhealthy protocol for giving people illusions of balanced weight loss.
