Best Weight Loss Program Overall: Noom

Noom is our pick for the best overall weight loss program because it goes beyond short‑term dieting to systematically retrain how users think about food, activity, and triggers. Its blend of daily psychology‑based lessons, structured tracking, and built‑in coaching and community support creates a more immersive experience than simple calorie‑counter apps, which can help you to adhere to new habits and support longer lasting success. 

Our Tester’s Thoughts on Noom 

A member of our team, Grant, tested Noom for a nine-month period and shared his thoughts on the app’s functionality, ease of use, accountability, safety, and more. For reference, Grant is a 27-year old man who is 5 foot 9 inches tall. He rated his overall experience with Noom as a 5 out of 5. “The app was very easy to use,” Grant said. “The app itself is basically a weight loss/calorie tracker with some fitness elements incorporated—I found it fairly easy to stick with.” 

The program’s recommendations are presented in a way that’s easy to understand, Grant said. It centers around replacing wasteful calories with other, more filling foods that can help you lose weight. “The program doesn’t necessarily provide a set meal plan, but it includes plenty of health-conscious recipes that are good. I prefer to cook for myself with recipes found online, and ended up using Noom to track those calories,” Grant said. 

Our tester was incredibly happy with his results after a nine-month trial, saying: “This program helped me lose nearly 70 pounds. I attribute the first 24 pounds that I lost directly to Noom—it helped me to understand that I was eating more calories than needed, which helped me clean up my diet. It felt like a game, getting to the right number of calories for my goals.” He stopped using Noom after about a year, once he reached his goal weight and he had learned how to build a sustainable diet. 

What Testers Think Could Be Improved 

When considering the accountability features, Grant rated his experience as a 4 out of 5. The app offers built-in support communities to encourage your journey. You do have to seek out the communities, he explained. But there are plenty of hyper-specific groups that you can join, such as active men, young folks, pregnant women, and more.  

Specs 

• Free trial length: 14 days 
• Special features: Psychology-based daily lessons, color-coded food logging system, and coaching-supported app 
• Calorie tracking: Yes 
• Coaching: Yes 

Best Weight Loss Program for Workouts: Simple

Simple is our pick for the best weight loss program for workouts because it weaves movement into the same daily flow as fasting and food tracking, using prompts, short workout clips, and a real‑time success score to nudge users to be more active throughout the day. In fact, research has shown that push notification reminders in this capacity can help improve weight-loss program adherence.  

Our Tester’s Thoughts on Simple 

Pete tested the Simple App for seven days to support his intermittent fasting routine with an overall weight-loss goal. He followed the plan consistently throughout the week. In general, Pete said he had a positive experience using the app, rating it a 4 out of 5. Plus, he found the recommendations in the app easy to follow, also rating them a 4 out of 5.  
 
“When I downloaded Simple, I was prompted to answer a series of questions about my age, current weight, dietary preference, eating habits, sleep patterns, activity level, and goals. This information allowed the Simple App to recommend a plan tailored to my specific goals,” Pete said. “If you have weight loss goals, you can enter your goal weight with the option to include a date or an event you’re trying to get in shape for. I set an upcoming 5K run event as my deadline, and Simple created a timeline for when I would expect to meet that goal if I followed the app’s guidance.” 

Pete thinks that Simple is a great choice for anyone wanting to try intermittent fasting with additional support for their nutrition or weight loss journey. There are premium personalized plans, but Pete found the free weight loss program to be robust and allows you to experience the app’s interface before deciding whether to upgrade to the paid subscription for additional personalized guidance. 

What Testers Think Could Be Improved 

Simple doesn’t have a community to talk to or personalized coaching. “The app does have an AI assistant, which can answer questions and provide guidance on healthy recipes, workout ideas, and improving your meal scores,” Pete said. “You can log your meals by taking photos or describing them in the app. Simple also offers easy-to-read articles written by a dietitian that provide extra guidance on nutrition and fasting. The accountability aspect comes from the app’s reminder system, which keeps you aware of when your fasting window starts and ends so you stay on track.” He rated the accountability aspect of Simple as a 3 out of 5. 

Calorie counting and macros aren’t part of the program, at least on the free version. The app does use a meal quality score, which is there to calculate nutrient density and calorie density together. 

Specs 

• Free trial length: None 
• Special features: AI coach “Avo” for real-time guidance, flexible intermittent fasting timers, quick meal and habit tracking with Nutrition Scores, and a daily plan with behavior-focused check-ins 
• Calorie tracking: Yes, but it’s not detailed 
• Coaching: Yes, AI 

Best Personalized Weight Loss Program: Reverse Health

Reverse Health is our pick for the best personalized weight loss program because it is designed for women over 40, tailoring nutrition, movement, and habits to changing hormones rather than forcing a one‑size‑fits‑all plan. The combination of customized meal plans, low‑impact home workouts, symptom‑aware education, and optional coaching creates a program that feels genuinely individualized. 

Our Tester’s Thoughts on Reverse Health 

After using the program for just over a week, our tester, Paige, gave her overall experience a 5 out of 5. “My overall experience was great,” she said. “I could absolutely see myself using this app long term to reach my goals. It was easy to stick to and fun to navigate.”  

Our tester was especially impressed with the ease of use for Reverse Health, rating the instructions a 5 out of 5. Paige loved taking advantage of the program’s meal plan recipes, trying a few out for herself. “The meals were surprisingly simple and satisfying. I did not feel like I was going hungry,” she said. “Plus, the recipes were very easy to follow and had simple ingredients.” 

On accountability, our team also gave Reverse Health an overall 5 out of 5 rating. The app sends push notifications as reminders to track food or complete workouts. Additionally, the program was incredibly customizable in Paige’s experience, making it easy to apply Reverse Health to her daily lifestyle.  

What Testers Think Could Be Improved 

We enjoyed that Reverse Health offered inclusive imagery for all body types, so the program felt supportive, according to Paige. “My only comment is that the pictures in the beginning while registering were clearly AI generated, and it would have been more encouraging to see real photos,” she said. That being said, Paige liked that she didn’t feel anything about the app was pressuring or shame-inducing.  

Specs 

• Free trial length: None 
• Special features: Personalized hormone-aware meal plans, low-impact workouts like Wall Pilates and chair yoga, 1:1 coaching, and integrated tracking for sleep, mood, symptoms, and daily habits 
• Calorie tracking: Yes 
• Coaching: Yes 

Best Weight Loss Program with Meal Planning: Mayo Clinic Diet

The Mayo Clinic Diet is our pick for best weight loss program with meal planning because it pairs a clear, medically backed framework with plug‑and‑play meal plans and recipes that take much of the guesswork out of what to eat. Its phase‑based structure, pyramid visual, and practical planning tools help folks to build weeks of balanced meals at a time, turning healthy eating into a repeatable routine rather than having to make daily decisions, which supports both weight loss and long‑term healthy habits. 

When you first start the program, Mayo Clinic allows you to choose from eight different meal plans, including Mediterranean, simple, healthy keto, original, heart smart superfoods, higher protein, and vegetarian, according to our tester, Pete. “Each of these meal plans come with daily recipes for breakfast, lunch, and dinner, and you can easily swap out recipes for different ones right in the app, making it very customizable,” he explained.  

Our Tester’s Thoughts on Mayo Clinic Diet 

Pete went with the high protein plan and was impressed with the recipes. “The recipes looked great. However, they definitely require a bit of knowledge in the kitchen,” he said, giving the instruction a 4 out of 5 score. “For those with less cooking experience, or those who want easy recipes then the Simple plan would work well since those recipes use minimal ingredients and are designed to be prepared within 15 minutes.” 

To avoid confusion, we’ll note that the Simple plan Pete referred to is a streamlined cooking plan within the Mayo Clinic Diet—distinct from the Simple weight loss program featured elsewhere in this article. 

Where accountability is concerned, the Mayo Clinic Diet earned a 5 out of 5 rating. The app sent Pete helpful, considerate notifications and reminders to complete a workout or track his meals. He thought the app was great at teaching healthy, sustainable habits.  

What Testers Think Could Be Improved

The program offers inclusive imagery and promotes safe, healthy eating habits. However, you’re only able to chat with a registered dietitian for users with insurance. We would love the Mayo Clinic to offer, for instance, a first free chat with a dietitian, followed by insurance-covered sessions thereafter.  

“I believe the program would be pretty easy to stick to if you had a decent amount of internal motivation. The reason for this is that although the meal plans, recipes, and grocery lists are included, the user would still need to prepare the meals, which is probably the most challenging part,” said Pete.  

Specs 

• Free trial length: Free “personalized plan” preview 
• Special features: Unlimited group coaching sessions with Mayo experts  
• Calorie tracking: Yes 
• Coaching: Yes 

Best Weight Loss Program for Calorie Counting: Nutrisystem

Nutrisystem is our pick for best weight loss program for calorie counting because it largely automates the hardest parts of eating in a calorie deficit: planning, portioning, and tracking. By delivering pre‑portioned meals tied to specific calorie levels, this reduces decision fatigue and guesswork, which can be especially helpful for folks who feel overwhelmed by tracking apps or meal prep.  

Our Tester’s Thoughts on Nutrisystem 

Overall, using Nutrisystem was a convenient and structured way to follow a calorie-controlled plan. The pre-packaged, portion-controlled meals made planning and prep virtually effortless, and the app helped Pete track meals and stay on schedule. He appreciated the variety of lunch and dinner options, which kept things interesting, though breakfast choices were a bit limited.  

“What worked well for me was the simplicity and structure. I didn’t have to think about meal planning and the pre-portioned meals made it easy to stay in a calorie deficit. I did need to add some snacks, and protein shakes to feel fully satisfied and get enough daily protein, because the program doesn’t adjust for your weight or activity level,” he said.  

What Testers Think Could Be Improved 

“The program is very structured, with simple guidance on when and what to eat, which aligns well with its primary goal of creating a calorie-controlled routine without requiring users to plan meals themselves,” Pete said. “The food you order is heat-and-eat, rather than ingredient-based meals that require cooking.” 

However, the app does offer an extensive recipe library for those who want to prepare their own meals. “This is helpful for people who order five days of meals per week and need guidance for cooking on their own during the weekends,” he said. Pete rated the ease of following instructions as a 3 out of 5. 

Specs 

• Free trial length: None 
• Special features: Structured plans for different needs (like diabetes, menopause, or low carb), and simple “no calorie counting” guidelines 
• Calorie tracking: Yes 
• Coaching: Yes 

Best Weight Loss Program for Eating Habits: WeightWatchers

Weight Watchers is our pick for the best weight loss program for eating habits because it uses a proprietary points system that replaces conventional calorie and nutrient tracking. The concept includes a PersonalPoints budget which tells you how many points you have available on a daily basis. WW then assigns point values to foods based on their nutritional profile, and you fit them into your plan. WW hosts meetings for users to discuss their weight loss journeys, encourage each other, and celebrate wins. This social support has been shown to increase program adherence and generate improved long-term weight loss results. 

Our Tester’s Thoughts on WeightWatchers

Pete tested WeightWatchers (also referred to as WW) for seven days and was able to be consistent with it for the entire week. Overall, he thinks that WW has a lot of positives for anyone looking to build healthier eating habits. The food point system is approachable and works well for people who don’t want the hassle of tracking calories or macros. 

He rated his overall experience with WW as a 4 out of 5. “The app itself is well-designed, offering plenty of useful features, including a barcode scanner for quick and easy tracking, the ability to log meals by taking a photo, and a robust recipe database. It also provides macronutrient data for protein, carbs, and fats, and includes a recipe analyzer that can generate point totals for virtually any recipe. There’s also a progress tab so you can keep track of your weight loss over time,” Pete added. 

Pete rated the instructions and recommendations from WW as a 4 out of 5. To start WW, users answer questions about their age, weight, food preferences, and activity level. Based on this information, the app generates a personalized Points budget, which tells you how many points you have available daily. Users can track their points throughout the day using the WW app. 

Tracking everything consumed is key to success with WW, as accuracy enhances the program’s effectiveness. “The app’s educational components help users build healthier habits by combining expert-led coaching, behavioral science, and practical nutrition tools. Through interactive workshops, personalized plans, and features like food scanning and recipe analysis, users learn how to make better choices in real time while also improving mindset, sleep, and long-term consistency,” Pete said. 

The WW app includes access to over 13,000 healthy recipes. They vary in complexity, but the majority are easy to follow and prepare, per Pete’s experience. 

What Testers Think Could Be Improved 

“Where WW falls short is in educating users on fundamental nutrition principles such as macronutrient balance and how to structure well-balanced meals,” said Pete. “WW also includes a list of ZeroPoints whole foods like lean meats, eggs, and non-starchy vegetables, which are intended to promote healthy eating habits. However, these foods are not zero calories, which may inadvertently lead to overconsumption and hinder weight loss efforts.”

Specs

• Free trial length: Often 30‑day or multi‑month free promos 
• Special features:  Personalized Points system with large ZeroPoint food list, robust food and barcode/photo scanners with automatic macro tracking, and access to expert coaches, workshops, and GLP‑1–integrated care options 
• Calorie tracking: Yes 
• Coaching: Yes 

Other Weight Loss Programs We Tested 

We tried fifteen weight loss programs and apps. Here are a few that we tested that didn’t make our list, and why. 

• Yazio: This app doesn’t include any educational components. It functions primarily as a calorie-counting and fasting tool, so we didn’t include it on our list. 
• Cronometer: While this app allows you to set specific nutrient and calorie counts, it doesn’t include any support. We selected apps that have built-in educational content and structured meal plans, as well as full recipes. 

How We Tested and Selected the Best Weight Loss Programs 

For each program, our evaluation focused on how well it supports safe, sustainable weight loss rather than fast, extreme results. Programs were reviewed for evidence‑based guidance, clarity of education, and how well the tools (apps, coaching, meal plans) help people build lasting habits. Some of the programs also offer healthy meal delivery services, which some folks may be interested in to help simplify their weight loss tasks.  

Types of Diets Offered 

We considered if programs use a specific dietary pattern (such as intermittent fasting, portion‑control, or a food‑group–based approach) and how flexible that pattern is in day‑to‑day life. Programs scored higher when they offered structure without being overly restrictive, included plenty of whole foods, and allowed for personal food preferences. Several programs we included also have a meal delivery service, which you may be interested in if you’d like to skip grocery shopping, planning, and even cooking. 

Accountability 

Accountability covered aspects such as access to coaching, group support, progress tracking tools, and reminders. Programs that provided multiple layers of support—such as in‑app check‑ins, coaching, communities, or structured progress reviews—were rated more favorably than those that left users largely on their own. 

Ease of Use and Instruction 

Ease of use included app or website design, clarity of instructions, and how simple it was to start a plan and follow it day to day. Programs that offered clear onboarding, step‑by‑step guidance, and intuitive tracking tools were prioritized over those that felt confusing, cluttered, or required a steep learning curve. 

Sustainability

Sustainability focused on whether a weight loss program can realistically be followed for months, not just weeks. Factors included flexibility around social eating, travel, and busy schedules, as well as emphasis on habits and skills rather than short‑term rules; programs that encouraged gradual, maintainable change ranked higher. 

Value

Value reflects how well the program’s price lines up with its features, level of support, and long‑term usefulness. The evaluation weighed cost against the quality of education, coaching, tools, and results potential to highlight options that deliver strong overall benefit—not just the cheapest, but the best value for what you get.

Benefits of Weight Loss Programs 

Weight loss programs can offer several advantages beyond the number on the scale: 

• Clear structure that reduces decision fatigue about what to eat and how to move. 
• Education about nutrition, exercise, and behavior change that you can use long‑term. 
• Accountability and support that help you stay consistent when motivation dips. 
• Tools for monitoring progress and adjusting your plan instead of guessing. 

Risks of Weight Loss Programs 

One of the biggest red flags is if no licensed providers are involved in the plan whatsoever. Any app that sets you under 1000 calories/day and does not require any bloodwork to ensure you’re healthy to diet is dangerous,” says James J. Chao, MD, FACS, Co-Founder & Chief Medical Officer, VedaNu Wellness. 

“Some of these meal replacement plans remove entire food groups for extended periods of time, which can cause micronutrient deficiencies in iron, B12, magnesium, and potassium. Deficiencies in these areas are no joke and can cause serious cardiac issues. Anyone promising you’ll lose 2 lbs. A week for extended periods of time is flat out lying, because your body will not allow it!” 

How to Find the Best Weight Loss Program for You

Start by deciding what you want most from a program: community support and accountability, structured meal plans, or convenience. From there, you can match those needs to programs that fit your health history, schedule, and preferences, ideally with input from your doctor. 

Your Personal Goals 

Different people have different goals—fat loss, muscle gain, performance, managing conditions like diabetes, or feeling more energetic. That means your ideal program might emphasize strength training, cardio, nutrition habits, or medical oversight in very different ways.  

Talking with your doctor or other qualified healthcare professional before starting any plan is important, especially if you have existing health conditions, are pregnant or postpartum, or take medications that may affect weight or exercise tolerance. 

Support System 

Several studies have shown that social support during a person’s weight loss journey can help with success.  

Some folks do best when they feel part of a community, whether that’s an in‑app group, live workshops, or a private group of friends and family. Others prefer to work more independently and may find social interaction distracting or draining. As you compare options, pay attention to whether a program offers group forums, coaching sessions, or live events, and whether that type of support feels motivating or overwhelming to you. 

Hands-On Accountability 

Some folks prefer regular check‑ins with a coach who reviews logs, adjusts goals, and offers feedback, which can be especially helpful if you struggle with consistency. Others feel comfortable using a self‑guided app and automated reminders and may only want occasional touchpoints, or no coaching at all. 

“Don’t do it alone,” says Dr. Chao. “The studies are pretty clear that the addition of human coaching is the most effective supplement to app-based dieting programs for long term retention, and I believe the reason is relatively straightforward; people tend to abandon digital programs, but they don’t quit on other people. Programs that offer live coaches and require check-ins each week or even every other week have been shown to retain up to 70% of clients at 6 months versus less than 20% for programs that operate exclusively through an app,” he said. 

“Food journals and activity trackers are great for the first month or two when you’re fired up, but logging everything you eat falls by the wayside almost immediately for most people. Support groups, virtual or local, have been shown to improve compliance by another handful of percentage points.” 

Meal Tracking Preferences 

Programs differ significantly in how they handle food: some emphasize calorie or macro counting, some use points or color systems, and others lean on portion sizes, journaling, or more intuitive approaches. If precise calorie counting is not for you, a gentler framework may be a better fit, while data‑driven personalities might enjoy logging every bite. 

Progress Tracking 

Progress can be tracked in many ways—scale weight, tape measurements, progress photos, fitness milestones, clothing fit, or habit streaks. Some programs encourage daily weigh‑ins and regular photos, which can be motivating for some folks and uncomfortable or discouraging for others. It helps to choose an approach to tracking that feels respectful and encouraging to you; consistent habits matter more than any single metric, and you can succeed without forcing yourself into tracking methods that don’t work for you. 

Frequently asked questions

Does insurance cover weight loss programs? 

Insurance sometimes covers weight loss programs, though it depends on your diagnosis, type of weight loss program, and your health insurance plan. 

What is the most effective weight loss program?

The most effective program is typically the one you can follow consistently while maintaining your physical and mental health. We picked Noom as our overall best program for weight loss; we like its daily lessons, structured tracking, and built-in coaching along with community support.

What is the best diet to lose weight?

There’s no one specific diet that is best for weight loss— many different dietary patterns can work—if they create a sustainable calorie deficit and provide enough protein, fiber, and micronutrients. The “best” one is the one you can maintain while feeling adequately fueled and satisfied.

What is the most effective form of weight loss?

The most effective approach typically combines nutrition changes, regular physical activity (especially a mix of resistance training and cardio), adequate sleep, and stress management. Habit‑based approaches usually lead to longer-lasting weight and health improvements.
