Noom vs. South Beach Diet

Let’s take a closer look at noom vs south beach and what it genuinely offers.

Here’s a genuine face-off between the latest in weight-loss technology and a low-carb plan that’s since reinvented itself as a meal delivery service. What do these two approaches actually have in common, and can you follow the South Beach Diet while using Noom?

Noom Vs South Beach: What Is Noom?

Noom is a 16-week weight-loss program built on the idea that psychology plays a much bigger role in weight loss than traditionally assumed. Developed with doctors, psychologists, nutritionists, and other health professionals, it offers a genuinely research-backed approach to losing weight.

What Is the South Beach Diet?

South Beach began as a low-carb eating plan, once considered a direct rival to Atkins. Today it’s transitioned into a meal delivery service closer to Nutrisystem — one of the more notable examples of a diet plan evolving into a full meal-delivery business.

Noom vs. South Beach Diet: History

Brief History of Noom

Founded in 2008, Noom underwent years of changes before really gaining traction in 2018, when Google listed it among the year’s top diet searches. In 2019, Noom partnered with Novo Nordisk, a global healthcare company, to further its mission against global obesity. The CDC has also recognized Noom as an official lifestyle program.

Brief History of the South Beach Diet

South Beach entered the mainstream in 2003 with Dr. Arthur Agatston’s book, The South Beach Diet: The Delicious, Doctor-Designed, Foolproof Plan for Fast and Healthy Weight Loss. The original plan was more accurately a moderate-carb diet than a strict low-carb one, since it allowed certain higher-carb foods.

Noom vs. South Beach Diet: Who’s Behind the Plans?

Who Created Noom?

Jeong developed the initial concept after six years living and working in Korea, later bringing the idea to Petakov, who was initially hesitant to leave Google but was drawn in by his own interest in the psychology of decision-making. The two launched Noom together in 2008.

Who Created the South Beach Diet?

Dr. Arthur Agatston created South Beach in 2003, releasing it as a book during the height of the low-carb diet trend. Despite the low-carb label, it functions more as a moderate-carb plan — with skipping carb counting as one of its key differences from Atkins.

Noom vs. South Beach Diet: The Rules

Rules of Noom

Noom has no fixed rules in the traditional sense — instead, it provides tools for food logging, exercise tracking, and daily wellness lessons, all through a single app.

Food Logging: Foods sort into green, yellow, and red categories functioning like a traffic light. Green foods (fruits, vegetables, non-fat dairy) typically make up around 30% of daily calories despite being encouraged most, simply because they’re so low-calorie. Yellow foods (higher-sugar produce, low-fat dairy, lean meats) usually account for about 45%, and red foods (fast food, high-fat, high-sugar items) are capped around 25%.

Exercise Tracking: Exercise earns back 50% of burned calories — burn 500 calories on a 1,500-calorie plan, and your allowance rises to 1,750.

Lessons and Quizzes: Around 10 minutes a day covering health, wellness, mental health, and stress management.

Rules of the South Beach Diet

The original South Beach Diet restricted carbs through several phases of gradual reintroduction. Today’s version is a meal delivery service with three tiers — Silver, Gold, and Platinum — each including breakfast, lunch, and dinner, with snacks and shakes added at higher price points. The current plan now markets itself as keto-friendly rather than simply low-carb, and still requires supplementing delivered meals with fresh groceries, similar to Nutrisystem.

Noom vs. South Beach Diet: Eating Plans

The Noom Eating Plan

Noom emphasizes whole foods and home cooking, though nothing is off-limits — prepared meals, delivery services, and other conveniences all fit within the program as long as they’re logged.

The South Beach Diet Eating Plan

South Beach delivers three meals and two snacks daily. Menu items rotate but have included dishes like a Tuscan-Inspired Egg Scramble, Margherita Pizza, and Sesame-Glazed Beef & Veggie Bowl, alongside snacks like Cheddar Cheese Crisps and Protein Puffs. Silver includes breakfast, lunch, and dinner five days a week; Gold adds snacks; Platinum adds keto-friendly shakes on top of that. Even at the highest tier, users still need to shop for and prepare several meals and snacks themselves each week.

Noom vs. South Beach Diet: Plan Duration

Noom’s active weight-loss phase runs 16 weeks, extendable as needed, with continued coach and community access available afterward. South Beach transitions users into a “Success” maintenance plan once their weight-loss goal is reached, according to the company’s FAQ.

Key Differences Between Noom and South Beach

The most obvious distinction: Noom is an app-based education program, while South Beach is now a meal delivery service. South Beach also remains restrictive in its current keto-friendly form, limiting carbs, while Noom avoids that kind of category-wide restriction entirely.

Can You Follow the South Beach Diet on Noom?

Yes — there’s no real conflict here. Noom’s extensive food database covers most commercial meals, and any South Beach items not already listed can be added manually in just a few taps.

Possible Side Effects

We found no documented side effects tied to either Noom or the South Beach Diet.

Noom vs. South Beach Diet: The Research

Noom’s research is substantial. A study of more than 35,000 participants found Noom helped 77.9% of users lose weight, with dinner logging tied to the best results. As Scientific Reports put it, “This study demonstrated the clinical utility of an app for successful weight reduction in the majority of the app users; the effects were more significant for individuals who monitored their weight and diet more frequently.” Additional research in Metabolic Syndromes and Related Disorders found that a “clinically-significant weight-loss effect” held up even at a 52-week follow-up.

The current South Beach meal-delivery program has essentially no dedicated research behind it, and even studies on the original book-based version are mixed. One analysis in the Journal of General Internal Medicine found that “over 67% of nutrition facts in a best-seller diet book may not be supported in the peer-reviewed literature,” reviewed by “a panel of expert reviewers.” A 2004 review in the Journal of Clinical Endocrinology and Metabolism was similarly cautious about low-carb, high-fat diets broadly, noting “current data do not support such unbridled enthusiasm for these diets, particularly in relationship to high-fiber, high-carbohydrate diets emphasizing intake of fresh vegetables and fruits.”

The Bottom Line: Noom vs. South Beach Diet

Today’s South Beach Diet and Noom have little in common beyond compatibility — you can technically use South Beach meals within the Noom app. What stands out most is that Noom is clinically proven, while the current South Beach program simply isn’t.
