As the weight-loss industry continues to evolve, you may feel the resources are finally available to lose weight, from weight loss programs to medications, such as Ozempic.

But a healthy weight takes more than just an injection or pill, research shows — it requires a comprehensive treatment plan that leads to real changes in our daily activities so we can keep the pounds off for good.

But if you are one of 70% of adults in the U.S. who are overweight and you want to make a change, where do you start?

You may have heard of the health dangers of ultraprocessed foods, which make up approximately 70% of American’s diet, and may be interested in cutting these out. Or you may have heard that food dyes are bad for you. While past research has found ultraprocessed foods do not cause chronic medical issues, like diabetes and heart problems, they are associated with them.

Nutrition and weight loss experts say dieters should strive for a nutritionally complete diet that includes carbohydrates, fat, protein, vitamins and minerals, as well as fiber, to not only promote gut health but also to keep us full — keys to hitting your weight goal and ingredients that can help lower your risk of chronic disease. Exercise, especially strength-training, can also promote overall health.

TODAY.com talked to several experts to put together a review of the best weight loss programs to help you decide what’s right for you.

Is a Diet the Same as a Weight Loss Program?

The goal of most weight loss programs is to help you stick to a certain eating pattern with the intention of making long-term lifestyle changes. The word “diet” can refer to the eating plan a person follows on such a program, or just a person’s general approach eating.

“I would separate a ‘diet’ from a program, which basically helps you stick to that ‘diet,’” Evan M. Forman, Ph.D., director of the Center for Weight, Eating and Lifestyle Science (WELL Center) at Drexel University in Philadelphia, Pennsylvania, tells TODAY.com.

“The dietary prescriptions that have been evaluated and compared are reduced calorie, or balanced calorie deficit, low fat, low carb, plant based and Mediterranean,” Forman, who is also a professor of psychology and brain sciences, adds.

Research shows that all these approaches can be equally effective, but the one that works best will depend on the person, he says.

“The main factor seems to be which dietary pattern allows a given person to feel satisfied and is sustainable over the very long term,” Forman explains.

What Makes a Good Weight Loss Program?

Ask yourself these questions:

Which Program Most Appeals to You?

Look for plans that include foods you enjoy, but make sure the plans are balanced with enough nutrients, according to Mayo Clinic guidelines.

Choose a program that will fit into your life, but don’t jump at one that promises quick fixes, Satya Jonnalagadda, a registered dietitian nutritionist, tells TODAY.com. “Instead, focus on nutrition and lifestyle changes — one healthy habit at a time.”

Does the Program Set Goals and Track What You Are Eating?

“Effective programs provide nutrition skills, and help you set weight, activity and energy intake, and make it reasonably easy to track your behavior against your goals, including tracking everything you eat,” Forman says.

A reasonable weight loss goal is typically 1-2 pounds per week, according to the National Institutes of Health.

Jamie Mok, registered dietitian nutritionist and national media spokesperson for the Academy of Nutrition and Dietetics, advocates for culturally competent weight loss programs that can increase the likelihood of long-term compliance and success.

“It’s incredibly important for weight loss programs to include cultural foods as this directly impacts a person’s adherence, sustainability and overall wellbeing,” Mok says.

Is Counseling Part of the Program?

Research shows that the most effective programs come with counselors who can help you build new diet and exercise habits.

“A large number of studies show that people tend to succeed only if they enroll in a structured, intensive program with expert coaches who meet regularly over a long period of time, such as 25 times in one year, in order to provide skills training, problem solving and accountability,” Forman says. 

Are Registered Dietitians and Certified Obesity Specialists Included?

Programs should include guidance from licensed, registered dietitians — not just generic nutritionists, says Dr. Christopher McGowan, gastroenterologist and obesity medicine specialist in North Carolina.

“Registered dietitian nutritionists (RDN) are the experts in food and nutrition who are trained to provide science-based, individualized nutrition advice,” Mok adds.

“RDNs’ nutrition plans involve a comprehensive assessment of a person’s health, including medical history, anthropometrics, blood and lab test results, physical signs and symptoms, diet history, and food and health care accessibility, to meet individuals where they are at.”

The program should be led by trained and certified obesity medicine providers — not just people calling themselves “weight loss experts,” McGowan advises.

Is Physical Activity Included?

Exercise helps to maintain a healthy weight and counters the loss in muscle mass that accompanies weight loss, according to Mayo Clinic.

Are GLP-1 Medications Included?

“Any legitimate medical weight loss program today should offer FDA-approved, brand-name GLP-1 therapies — like Wegovy or Zepbound — when appropriate,” McGowan says.

Only a qualified provider should prescribe these mediations, and they should be paired with structured monitoring and care, he adds.

Does the Program Include a Maintenance Plan?

“A comprehensive weight loss program aims not just for weight loss, but for sustainable weight management,” Mok says.

She notes that a robust maintenance plan equips individuals with the strategies and support needed (such as coaching or peer-to-peer and group support) to keep the weight off for the long term, preventing weight regain and ensuring lasting success.

Who’s Leading the Program?

Medical leadership matters, McGowan says. 

“When a weight loss program is vetted by leading nutrition experts and health organizations, it signifies robust scientific backing as an effective approach for sustainable weight management,” Mok adds.

Which Weight Loss Programs Should Be Avoided?

“Be wary of any clinic that makes guarantees or promises specific results,” McGowan says. “Transparency is non-negotiable.”

Mok and McGowan also recommend looking for programs that are flexible and practical — and avoiding:

  • “Prescription mills” or online clinics that only offer medication without ongoing check-ins, coaching or nutritional support.
  • Clinics offering compounded semaglutide or tirzepatide as “alternatives” to FDA-approved treatments.
  • Programs that exclude traditional cultural foods (as it can feel restrictive, alienating and unsustainable).
  • Those with overly rigid rules, which can lead to feelings of deprivation, guilt and, eventually, a cycle of restriction and overeating.

What Are the Best Weight Loss Programs?

The best weight loss program for you will be one you enjoy and can stick with, the experts say. Before starting any new weight loss programs, consult your doctor.

If you are having trouble finding the right one for you, look for programs attached to medical centers.

“The best weight loss programs are the academic programs or community programs attached to a medical center run by obesity medicine specialists that offer lifestyle medications, psychology and metabolic surgery options — with a multidisciplinary team,” says Dr. Caroline Apovian, professor of medicine at Harvard Medical School and co-director of the Center for Weight Management and Wellness at Brigham and Women’s Hospital.

Based on interviews with dietitians, existing research and rankings, and information from the program’s websites and spokespeople, TODAY.com created a list of the best weight loss programs, including pros and cons for each program:

  • WeightWatchers Points Program
  • Mayo Clinic Diet
  • National Diabetes Prevention Plan
  • TOPS Club
  • Noom Weight
  • WeightWatchers Clinic
  • Cleveland Clinic Diet App
  • Jenny Craig
  • Nutrisystem
  • Keyto

Trying any new weight loss program may affect your digestion, blood sugar and overall health, so consult your health care provider before doing so.

WeightWatchers Points Program 

Rated the No. 1 diet for weight loss by U.S. News in 2025, the WeightWatchers Points Program assigns every food a “Point value” based on calories, protein, added sugar, saturated fat, unsaturated fat and fiber, Michelle Cardel, Ph.D., dietitian and Chief Nutrition Officer at WeightWatchers, tells TODAY.com.

Foods higher in protein, unsaturated fat, and fiber will be fewer Points, while foods higher in calories, added sugar and saturated fat will be more Points.

All members receive a personalized Points Budget, calculated based on their individual metabolic rate, determined by age, height, weight, sex assigned at birth and goals. Participants need to stay within their points budget to lose weight.

Any calorie-based system can help with weight loss, but the Weight Watchers Points Program “consistently (produces) weight loss and (improves) diet quality, (and) studies show that our program improves quality of life by 16% through our enhanced, holistic model of care,” Cardel says.

Nutrition experts say the program is simple to follow and provides a lot of support through the app features and members-only social network.

Users can upload a picture of the food they are planning to eat to its app, which then automatically calculates the food item’s ingredients, portions and points.

“I know many individuals who have had success on WeightWatchers, perhaps because no food or beverage is off limits,” Michelle Jaelin, registered dietitian, tells TODAY.com. “Too much restriction on most diets leads to failure.”

Mok adds: “Members have access to individual nutrition coaching with a registered dietitian, which is a major bonus for personalized guidance, accountability and long-term success.”

Pros

  • No food or beverages are off limits
  • Over 350 low-calorie but filling foods that don’t have to be tracked
  • Easier than other programs to sustain long term
  • Personalized nutrition counseling with dietitians and in-app social network
  • Food scanner and recipe analyzer
  • 24/7 virtual chat to share tips, recipes and solutions for common challenges

Cons

  • Weekly recommended weight checks may feel stressful
  • Possibly too lenient for some people struggling with self-control
  • Food-tracking and counting points can feel time-consuming
  • Regular changes to program due to changing science may feel frustrating

Mayo Clinic Diet

The Mayo Clinic Diet focuses on eating healthy foods by teaching how to estimate portion sizes and plan meals while increasing physical activity.

“It is a lifestyle change program,” Dr. Donald Hensrud, editor of “The Mayo Clinic Diet,” tells TODAY.com. He adds that the only necessary cost is “The Mayo Clinic Diet” book and, if desired, “The Mayo Clinic Diet Journal,” he says.

Digital resources, including food tracking, group coaching, meal plans and recipes, and other educational tools, are also available.

“By consuming generous amounts of foods that are high in bulk but low in calories, such as vegetables and fruits, people can feel satisfied yet consume less calories” adds Hensrud, an internal medicine physician specializing in nutrition and weight management.

The diet is divided into two phases: The first is called “Lose It!” and the second is called “Live It!”

“In the two-week ‘Lose It!’ phase, participants change 15 habits, and in the ‘Live It!’ phase, people take these habits and turn them into a long-term change program,” Hensrud explains.

The program now offers eight meal plans to personalize the weight loss journey, including a “freestyle” plan, as well as Mediterranean, protein, keto, vegetarian and one for those on GLP-1s.

One new feature is the Mayo Clinic Diet Score, a 100-point scoring system based on your current habits and behaviors. The higher your score, the more potential for weight loss over the long term. People can also get one-on-one dietitian support from board-certified registered dietitians.

Multiple nutrition experts TODAY.com interviewed rate this program among their favorites.

 “The Mayo Clinic Diet program promotes sustainable weight loss by focusing on building healthy eating and lifestyle habits, a research-supported approach that moves beyond calorie-counting or food-weighing,” Mok says.

Pros

  • Not focused on counting calories
  • Inexpensive
  • Manages weight for the long term
  • Different menus and recipes for Mediterranean, higher protein, healthy keto and vegetarian eating preferences
  • Provides specific guidance for people with diabetes and heart disease

Cons

National Diabetes Prevention Program

“The National Diabetes Prevention Program’s lifestyle change program helps people who are at high risk for Type 2 diabetes to make healthy changes — including losing a modest amount of body weight — that can prevent or delay Type 2 diabetes,” Christopher Holliday, Ph.D., director of the U.S. Centers for Disease Control’s Division of Diabetes Translation, tells TODAY.com. 

“The lifestyle change program helps participants eat healthier, get more physical activity, manage stress, and cope with life’s challenges that can make it difficult to stay on track.” 

Participants have access to CDC-approved resources, support groups, and a lifestyle coach to help them build healthy habits that last a lifetime, he adds.

The program is divided into two parts with a CDC-approved curriculum. The first six months, you are meeting approximately once a week, where people learn to eat healthy, add more physical activity to their lifestyle, learn to deal with stress and challenges in life that can disrupt your progress.

The second half, you meet less frequently and focus on maintaining the lifestyle changes you made. You work with a “lifestyle coach” and have peer support to motivate you.

“Research shows that people who participate can cut their risk of developing Type 2 diabetes by more than half,” Holliday says. “The year-long program is offered in-person, as well as … virtually, and it is covered by many employers and insurance providers, including several state Medicaid programs.”

Pros

Cons

  • Cost varies
  • Primary goal is to prevent diabetes
  • Need to meet eligibility criteria to participate
  • People with Type 1 or 2 diabetes not eligible

TOPS Club

TOPS Club, which stands for Take Off Pounds Sensibly, has been around since 1948 and now has about 6,000 chapters across the U.S. and Canada.

“In a nutshell, TOPS connects people of all backgrounds, many of whom cannot afford expensive commercial programs, through our network of weight‐loss support groups,” Michelle Ganley, director of communications of TOPS Club, tells TODAY.com.

“When you become a member of a chapter, you’re joining a group of people with similar healthy living goals. It’s that accountability that our members swear by — showing up for one another week in and week out, at regularly scheduled meetings.”

The program does not have any formal counseling as it’s centered on peer-to-peer support.

“For effective behavior change, especially in weight loss, peer accountability is key,” Mok says.

The program has 5 steps:

  1. Committing to a healthy lifestyle
  2. Deciding how you would like to attend meetings — either virtually or in person
  3. Signing up (newcomers can pay $70 for the year)
  4. Participating in the program (including learning the Exchange System to simplify how to eat)
  5. Celebrating the results you want

Members have access to a variety of meal plans on the website, with a 28-day meal plan that’s recommend for new members when they first join. There’s no official diet to follow, but many follow the Food Exchange System, created by the American Diabetic Association, Ganley notes.

Dr. Nia Schwann Mitchell, weight management specialist at Duke University, tells TODAY.com that a “unique” aspect of TOPS Club is that “people are expected to continue in the program and participate weekly, even after they reach their goal weight.”

Her research shows people who participate in the TOPS program for at least one year can lose up to 5-7% of their initial weight and maintain the weight loss for up to seven years.  

“As with other weight loss strategies, when people stop doing the things that helped them lose weight, they gain it back,” she adds. 

Multiple nutritionists TODAY.com interviewed gave high marks to this program. “TOPS clubs offer an inexpensive and easily accessible support system via virtual and in-person meetings,” Mok says.

Pros

  • Online and virtual options
  • Strong support among people who are going through similar experience

Cons

  • No official diet to follow   
  • No formal counseling
  • Support varies by local chapter

Noom Weight

Rated best weight loss app for behavior modification by Healthline in 2025 and second best diet program by U.S. News and World Report in 2025, Noom Weight is a virtual weight management program that helps lose weight by focusing on the mental aspects of weight loss. 

The program focuses on the cognitive process of eating behaviors, helping individuals build healthy habits to adapt to a healthier lifestyle, Jaelin says.

After users take an online quiz, the app provides a plan (often for 16 weeks) with suggested caloric intake, complete with daily lessons to help change the way you think and feel about eating, according to the company website. The user tracks everything they eat, which is categorized into green, yellow or orange foods, with the goal to eat a balanced amount of all the colors, according to its website.

People are encouraged to eat mostly “green” foods (like vegetables), which are the least calorie-dense and most nutrient-dense options; eat “yellow” foods, like lean meats and starches, in moderation; and eat sparingly “orange” foods, which are the most calorie-dense, like desserts and red meat.

“We help our users better understand their relationship with food, how to be more mindful of their habits, and give them the knowledge and support they need for positive health outcomes — including guiding them through lessons and habit-forming exercises to enhance understanding and integration of our ‘four pillars of health’ (sleep, exercise, nutrition, and stress management),” a Noom spokesperson tells TODAY.com.

Pros

  • Daily lessons to help change habits and behaviors
  • Coaching support via chat inside app
  • Tracking tools for food and exercise to hit goals at a personalized pace
  • No food off limits or point systems
  • Noom Med option for those interested in weight loss medications

Cons

  • No in-person coaching
  • Some may find it time-consuming to log everything they eat on a daily basis
  • Because self-help is a big focus, it may not work for everyone
  • Color coding can be inconsistent
  • Less portion control guidance
  • Pricey

Cleveland Clinic Diet App 

“The app offers nutritional and health-related information from experts in nutrition, endocrinology, metabolism, heart health, digestive health, weight management and mental health,” Michelle Dodd, registered dietician at Cleveland Clinic, tells TODAY.com.

She emphasizes the on-boarding questionnaire, which allows the user to personalize their program and guiding them with education so they learn there’s a reason to choose certain foods over others based on the health benefits.

“It is designed for the user to understand diet and nutrition, make the user more empowered and educate them on healthier diet and lifestyle choices,” she adds.

The program offers two diet plans: the HeartSmart plan, which has a more Mediterranean diet and cardiac health focus, and the BodyGuard plan, which is rooted in the principles of the HeartSmart plan but with a more weight loss focus. 

 Pros

  • Intake tracking with scanning, photos or voice inserts
  • Both plans focus on anti-inflammatory nutrition
  • Integrates with Apple Health, FitBit and Garmin for physical activity tracking

Cons

  • Not free (but has a free seven-day trial before a subscription is required)
  • Only has two plans
  • No diet plans for specific conditions other than weight loss and heart health

Jenny Craig

Jenny Craig is an entirely virtual program of prepackaged meal plans that incorporate the principles behind intermittent fasting to achieve weight loss.

Intermittent fasting can be an effective approach to weight loss or weight management, mostly because it tends to reduce people’s total energy (calorie) intake, says Monica Reinagel, licensed nutritionist and host of the Nutrition Diva podcast.

“In particular, it often reduces evening snacking, which is often a source of a lot of excess and nutritionally poor calories,” she adds.

Eating a ‘recharge bar’ at the end of the fasting period simply shortens the fast, but any weight loss achieved on this or any other approach is likely to last only as long as you continue the program, she says.

Jenny Craig is rated the third-best diet program by U.S. News and World Report in 2025, but the company has now shifted into a virtual model after it was bought by the owner of Nutrisystem. earlier this year.

Jenny Craig users first choose among several meal plans, including:

  • Jenny Craig plan: two-week shipments of meals under 300 calories, including 14 breakfasts, 14 lunches, 14 dinners and 14 snacks and deserts. You can either customize or choose from customer favorites.
  • Club Jenny: a “DIY” choice that gives full access to the Jenny Craig plan, complementing those who choose their own weight loss methods, like intermittent fasting and low carb.
  • Meal Delivery Plan: 14 breakfasts and 14 entrées every two weeks, plus full access to Club Jenny for six months.

Users eat during a 10-hour “nourishment period” window, then take a break for a 14-hour “rejuvenation period,” which includes sleep. Members also get “recharge bars” that they can eat in the last two hours of the fasting period to curb hunger. Weekly coaching is also available.

Pros

  • Defined meal plans
  • Coaching available
  • Structure approach to eating
  • Good for heart health and those with Type 2 diabetes

Cons

  • No in-person coaching
  • Long periods without eating
  • Possible weight gain if losing pounds too quickly or stopping program

Nutrisystem 

Rated among the top five diet programs by U.S. News and World Report in 2025, the program centers on balanced, premade meals and controls calories and hunger by eating frequently throughout the day, according to its website.

You first select a plan based on your age and sex. Similar to Jenny Craig (which Nutrisystem acquired), the program has three plans:

  • Nutrisystem Program, with the option of “chef choices” or a more customizable option. People get meals (breakfasts, lunches, dinners and snacks) five to seven days a week.
  • Meal Delivery Plans, including four main options: high protein (up to 30 grams of protein per meal), low carb (less than 25 grams carbohydrates per meal), menopause and balanced (by Jenny Craig — each meal is less than 300 calories). Each plan includes 14 ready-to-eat meals every week plus expert support.
  • Club Advantage Membership, the most personalized option. People can purchase any amount of meals that fits their approach to weight loss.

Nutrisystem delivers meals and snacks to your home. You then follow their app to know exactly what to eat and when (usually six times a day, which includes “grocery add-ins,” like low-fat plain yogurt and apple slices with almond butter) while having daily access to coaches as needed. The premade meals focus on lean proteins, healthy fat and certain “smart” carbohydrates combined with fiber and vegetables, according to the company’s website. 

“This approach can be a good start for those looking for meal ideas or (who) need something quick and easy to fit into a busy lifestyle,” says Lacy Puttuck, registered dietitian who specializes in weight loss and weight management.

Pros

  • No counting calories
  • Minimal cooking
  • Customized plans and modifiable meals
  • App provides support and resources

Cons

  • Limited options for eating out
  • Hard to sustain weight loss over long term
  • Contains high sodium levels
  • Not suitable for people with soy or peanut allergies 
  • Not fresh foods, which lowers nutrient value of meals

Keyto Diet

Rated among the best diets for fast weight loss by U.S. News and World Report in 2025, the Keyto diet is a low-carbohydrate diet that emphasizes Mediterranean diet foods and fats that help people “lose weight with no hunger,” according to its website.

First you create your personalized plan with a short questionnaire, and then you get the Keyto app. It includes a 16-week course, a customized lesson plan, a searchable food database, meal plans, recipes and a podcast for members. All members get coaching from a goal specialist, dietitian and personal trainer, per its website.

“This now has the option of coming with a breath sensor to measure metabolism,” Puttuck says. “Long-term study results are not available regarding this technology and the effect on weight loss.”

Pros

  • Fast weight loss
  • Recipes can be easily adjusted to dietary preferences
  • No counting calories or points
  • Diet rich in high-fiber foods

Cons

  • Sustainability may be an issue (as with all high-fat diets)
  • Can lead to nutritional deficiencies
  • May not work for people with gallbladder issues or irritable bowel syndrome
  • People with diabetes should talk to their doctor first before starting program
  • Regular lab work to watch cardiovascular health is recommended
  • Breath sensor complicates nutritional choices by changing diet daily

Before starting any new weight loss programs, consult your doctor.
