WW is one of the most well-known weight loss programs, based on a point system where every food and drink is assigned a SmartPoints value. The program encourages balanced eating by promoting healthier food choices like fruits, vegetables, lean proteins, and whole grains. WW also emphasizes behavioral changes through support meetings, online tools, and coaching.

2. Volumetrics Diet
Key Features
The Volumetrics Diet focuses on the concept of energy density, encouraging dieters to consume foods that are low in calories but high in volume, such as fruits, vegetables, and broth-based soups. This allows individuals to feel full while consuming fewer calories. The diet emphasizes eating foods with high water content and low energy density, which can help control hunger and reduce calorie intake.
Health Benefits
- Promotes Satiety: Eating high-volume, low-calorie foods helps curb hunger.
- Sustainable: It encourages a balanced diet, making it easier to follow long-term.
- Improves Digestion: The emphasis on fiber-rich foods supports healthy digestion.
Potential Challenges
The diet requires careful meal planning and might not appeal to those who prefer richer, more calorie-dense foods.
3. Noom
Key Features
Noom is a modern, app-based weight loss program that combines psychology with personalized coaching to help users adopt healthier habits. The program uses a traffic-light system to classify foods into green (nutrient-dense, low-calorie), yellow (moderate-calorie), and red (high-calorie) categories. It also focuses on daily logging and behavior change to foster sustainable weight loss.
Health Benefits
- Behavioral Focus: The program helps users understand the psychological triggers behind eating habits.
- Personalized Coaching: Users have access to coaches who provide motivation and guidance.
- Long-Term Success: The emphasis on habit formation supports lasting lifestyle changes.

Noom’s daily food logging and app usage may feel overwhelming for those who prefer less structure, and the subscription cost can be prohibitive for some users.
4. Nutrisystem
Key Features
Nutrisystem is a meal-delivery program that provides pre-portioned, ready-to-eat meals designed to help users lose weight. The program simplifies weight loss by controlling portion sizes and providing balanced meals, making it easy for users to stick to their goals without worrying about meal prep or grocery shopping.

- Convenience: Nutrisystem’s pre-packaged meals eliminate the need for meal planning and cooking.
- Portion Control: Meals are designed to provide balanced nutrition and prevent overeating.

Some users find the packaged meals less flavorful or enjoyable compared to fresh home-cooked meals. Additionally, the cost of ongoing meal delivery can add up over time.
5. SlimFast Diet
Key Features

10. HCG Diet
Key Features
The HCG Diet combines a very low-calorie diet (VLCD) with hormone injections or supplements of human chorionic gonadotropin (HCG). The diet typically restricts intake to 500-800 calories per day while the HCG hormone is believed to suppress hunger and promote fat burning.
Health Benefits
- Rapid Weight Loss: The severe calorie restriction leads to quick weight loss.
- Appetite Suppression: HCG is thought to reduce hunger, making the low-calorie intake more tolerable.
Potential Challenges
The extreme calorie deficit and reliance on hormone injections make this diet highly controversial. Many healthcare professionals do not recommend it due to safety concerns, and the potential for nutrient deficiencies is high. It’s recommended to consult your doctor before this diet.
11. The Cambridge Diet
Key Features
The Cambridge Diet is similar to the Cambridge Weight Plan and is based on very low-calorie meal replacements. It is typically used for short-term weight loss and involves drinking shakes, soups, and bars while following a strict calorie-controlled plan.
Health Benefits
- Rapid Weight Loss: The very low-calorie diet promotes fast fat loss.
- Simple Structure: The focus on meal replacements makes it easy to follow.
- Nutritionally Balanced: Despite the low-calorie intake, the products are designed to be nutritionally balanced, providing essential vitamins and minerals during the weight loss process.
Potential Challenges
The extreme calorie restriction can make the diet difficult to sustain over the long term. Additionally, transitioning from meal replacements to real food requires careful planning to avoid weight regain.
12. 17 Day Diet
Key Features
The 17 Day Diet consists of four 17-day cycles, each focusing on different aspects of weight loss and healthy eating. The first phase is the most restrictive, focusing on lean proteins, low-glycemic vegetables, and probiotics. As you progress through the cycles, more foods are gradually introduced.
Health Benefits
- Phased Approach: The gradual increase in variety helps prevent weight loss plateaus and ensures long-term success.
- Focus on Healthy Habits: Each cycle introduces new healthy eating practices that can be adopted for life.

Potential Challenges
The restrictive nature of the first cycle can be difficult for some people to follow, and meal planning can be time-consuming due to the frequent changes in the diet.
13. Medifast Diet

Key Features
The 3-Day Diet is a short-term, low-calorie diet that promises rapid weight loss. It involves eating a strict menu of very low-calorie foods, such as grapefruit, tuna, and eggs, over the course of three days, followed by four days of normal eating. The cycle can be repeated until the desired weight is achieved.
Health Benefits
- Quick Weight Loss: The extreme calorie restriction leads to rapid fat loss over the three days.
- Simple and Short: The program is easy to follow for a short period of time.
Potential Challenges
The diet is highly restrictive and can lead to nutrient deficiencies if followed for extended periods. Additionally, most of the weight lost is likely to be water weight, which can be regained once normal eating resumes.
16. Five-Bite Diet
Key Features
The Five-Bite Diet is an extreme weight loss program that encourages dieters to skip breakfast and then eat only five bites of food for lunch and five bites for dinner, regardless of the type of food. The premise is that by eating fewer calories, the body will burn fat for energy.
Health Benefits
- Rapid Weight Loss: The extreme calorie restriction leads to fast results.
- No Food Restrictions: Dieters can eat any type of food they like, as long as they stick to the five-bite rule.
Potential Challenges
This diet is highly controversial due to its extreme nature and the potential for nutrient deficiencies. The severe calorie restriction is not sustainable long-term, and most healthcare professionals do not recommend it as a healthy approach to weight loss.
17. Fast 800 Diet
Key Features
The Fast 800 Diet, developed by Dr. Michael Mosley, is based on intermittent fasting and a Mediterranean-style low-carb diet. It involves consuming 800 calories per day for a short period (2-12 weeks), followed by a more sustainable eating pattern with two fasting days per week.
Health Benefits
- Intermittent Fasting: The fasting element can help improve insulin sensitivity and promote fat burning.
- Mediterranean Focus: The emphasis on whole foods, healthy fats, and lean proteins supports heart health and longevity. Check out our Plant-Based Diet page for more Mediterranean like diets.

Potential Challenges
The initial phase can be difficult to maintain due to the severe calorie restriction, and some people may struggle with hunger or fatigue during the fasting periods.
18. Mayo Clinic Diet
Key Features
The Mayo Clinic Diet emphasizes long-term healthy habits and lifestyle changes rather than quick fixes. The program is divided into two phases: “Lose It!” and “Live It!” During the Lose It! phase, participants focus on changing unhealthy habits and losing weight, while the Live It! phase teaches how to maintain the weight loss through balanced eating and regular physical activity.
Health Benefits
- Healthy, Sustainable Weight Loss: The focus on lifestyle changes promotes lasting results.
- Balanced Nutrition: The diet encourages a wide variety of nutrient-rich foods.
- Holistic Approach: The program promotes overall health, including physical, mental, and emotional well-being.
Potential Challenges
