What's the Best Popular Diet?

For those who'd like to drop a few pounds or maybe even shed 100 or more, there's no shortage of services promising to make that dream a reality. Are there any diets that actually work?

The good news is yes, there are many weight loss programs with a solid track record of helping people redefine their relationships with food, learning what and how much to eat, and making changes that aren't just a temporary low number on the scale. But as you've probably noticed, every popular diet seems to have a different approach to shedding unwanted pounds.

5 Star Rating TopConsumerReviews.com Best-In-Class Blue Ribbon Award

Noom is the new kid on the block among popular diets, and it quickly earned our top spot.

Noom is the best diet plan on the market for making long-lasting changes that result in sustained weight loss.

Weight Watchers Review 4.5 Star Rating

Weight Watchers

4.5 Star Rating

There's a reason why Weight Watchers, also known simply as WW, stays at the top of most lists for weight loss. This program has helped people lose weight for more than 5 decades. Although you won't get food conveniently delivered to your doorstep, you will get a range of tools and support to help you on your journey, with options for in-person meetings or digital-only plans. Plus, WW is the only popular diet plan we found that offers you rewards for your healthy habit "wins" over time. This is a great option for most people who are looking to lose weight and establish healthy habits for a lifetime.

Nutrisystem Review 4.5 Star Rating


4.5 Star Rating

Nutrisystem is our first choice among diets that revolve around delivered, premade food. Unlike its competitors, this program doesn't require you to cut carbs extensively, forego dairy, fruits or other major food groups. Instead, you'll achieve weight loss through carefully-portioned meals and snacks designed to help you limit your caloric intake while still eating familiar foods like hamburgers and pasta. Although the program can be spendy, Nutrisystem consistently delivers long-term weight loss for most of its subscribers.

South Beach Diet Review 4 Star Rating

South Beach Diet

4 Star Rating

South Beach is a top choice among popular diets that take a high-protein, low-carb approach to weight loss. Unlike comparable diet plans, this program offers more flexibility in the "do" and "don't" foods, while still offering the convenience of pre-made meals and snacks delivered directly to your doorstep. The program is a little spendy, but might be well worth it if you don't want the hassle of grocery shopping and extensive time in the kitchen.

Keto Review 3.5 Star Rating


3.5 Star Rating

When you first hear about the keto diet, you might think that losing weight eating high-fat foods like meat and butter sounds like a dream come true. Many people do experience a significant initial weight loss with this popular diet, along with reduced cravings for sugar and carbohydrates in general. This can be a life changer for those with diabetes or blood sugar issues.

Paleo Plan Review 3.5 Star Rating

Paleo Plan

3.5 Star Rating

The paleo diet focuses on the kind of eating people used to do before the agricultural revolution: fish and meat, fruits and vegetables, eggs, and some nuts/seeds. If you "go paleo", you'll need to forego dairy, grains, and refined sugars. Paleo Plan can help you discover new and delicious ways to stick to your paleo goals. Just be aware that, for many people, the paleo diet works for an initial quick weight loss but isn't a way of eating that they want to follow for a lifetime.

Atkins Review 3 Star Rating


3 Star Rating

Atkins has been a popular diet for decades. As one of several eating plans that focuses on low carb intake, you'll find yourself eating a lot of proteins and vegetables. The Atkins site offers numerous free tools like a mobile app for food tracking and more than 1000 recipes. But, many people who try the Atkins diet find it too restrictive, especially when trying to limit their carb intake to just 20g per day.

Meal Plan Map Review 3 Star Rating

Meal Plan Map

3 Star Rating

Meal Plan Map might not be what you would consider a true "diet". Instead, this app helps you focus on one of six nutritional goals, including healthy weight or anti-inflammatory foods, and gives you loads of tools for meal planning and prep, tracking your nutrition and exercise, and more. This program has a free 1-week trial and an affordable monthly subscription price. But, because Meal Plan Map is much less structured than most popular diets, you may feel overwhelmed and less successful in reaching your weight loss goals.

Whole 30 Review 3 Star Rating

Whole 30

3 Star Rating

Whole30 is one of the most drastic of today's popular diets: no dairy, grains, legumes, alcohol, or added sugars (including alternatives like stevia) for a whole month. If you're already a big fan of meat, seafood, eggs and vegetables, you'll have no problem sticking to this program. Or, if you need help figuring out if you have food allergies, this could be your perfect plan. But, for most people, Whole30 is challenging to complete successfully.

Medifast Review 2.5 Star Rating


2.5 Star Rating

Medifast can help you achieve quick weight loss through their convenient packaged kits. There's no calorie counting - or even much cooking - involved with this popular diet plan. Instead, you'll eat 5 prepackaged small meals and snacks every day, and just one that you prepare yourself. This plan is a good choice if you want to lose weight fast and won't miss fresh fruits and vegetables, but this won't teach you how to eat healthy for a lifetime.

Some diet plans will tell you that you have to count every calorie, while others want you to focus on eating more whole and unprocessed foods instead of tracking what you eat. Whichever plan you select, it's important to make sure that it's a program you can realistically follow, based on your current lifestyle. For example, if you frequently travel for work, can you stick to a diet that requires you to cook with hard-to-find ingredients and a full spice cabinet on hand?

And, unless you just want to drop a dress size for an upcoming school reunion or other event, you probably want to find a plan that helps you make sustainable changes for a lifetime. It's easy to do something drastic for a week or even a month, but to avoid the yo-yo effect of fad dieting, you should be honest with yourself about what changes you are able and willing to make - and which ones just aren't the right fit for your personal needs, preferences, and goals.

As you consider the many popular diets offered today, how can you figure out which ones will be the best fit? Here are several criteria to keep in mind:

  • Cost. What will you pay for the diet plan? Is it a one-time investment, a monthly subscription, or some other pricing structure? Does it give you a good value for your money?
  • Time Required. How much effort will you need to put into following the diet? Are your meals premade and delivered, or should you expect to spend a lot of time in the kitchen?
  • Customer Feedback. What do "real people" have to say about their success (or lack of it) when following this diet plan? Most sites will show you their best-case results, but what can an average person expect in terms of weight loss and other health benefits?
  • Personalization. Just like clothes aren't truly one-size-fits-all, neither is dieting. Does the diet plan have a way to customize their recommendations for food, exercise, and more? Do you get any one-on-one input from a coach, nutritionist, or even through an online community of other people using the plan?
