What is a weight loss program?

A weight loss program is a regimen for diet and exercise. The best diet program for weight loss helps you achieve healthy lifestyle changes and provides guidance on food and nutrition to support short- and long-term weight management.

How do weight loss programs work?

Weight loss programs offer guidance and support based on your personal dieting goals and nutritional needs. The most effective weight loss programs often require more homework but provide a better fit than one-size-fits-all plans.

Guidance on food and nutrition: Ask yourself if you want the bulk of your diet to be frozen meals and prepackaged snacks or if you prefer the flexibility of cooking meals and occasionally eating out. Diet plans sometimes rely on meal replacement shakes to provide healthy nutrition. Some weight loss programs, such as Medifast and Nutrisystem, deliver frozen entrees and prepackaged snacks for easy portion control. Others create personalized meal plans and provide recipes for dieters to cook themselves.
Exercise requirements: Dieters have the most weight loss success when a healthy meal plan is combined with an exercise routine. Some weight loss plans focus entirely on diet, but most safe weight loss programs incorporate exercise directives and lifestyle strategies that naturally speed up your metabolism, which helps you lose weight and keep it off.
Weight loss support: The easiest weight loss programs include community support. Regularly connecting with fellow dieters helps many people stay motivated. Online and in-person workshops and forums are also a great way to find new dieting tips and learn about weight management tools.

Some weight loss programs rely on mobile applications for meal planning, counseling and support, while others provide in-person workshops. In-person group meetings are regularly scheduled at community centers or businesses. Participants can engage in group discussions, breakaway groups or one-on-one sessions with other members or program counselors to discuss realistic weight loss goals.

Types of diets to lose weight

What works for one dieter doesn't always work for another, which makes it tricky to find the right diet for you. For many people, the first step to finding the healthiest weight loss program is having an honest conversation with their health care provider. A doctor or nutritionist can help you decide if a low-carb and high-protein diet, low-fat and low-calorie diet, plant-based diet or meal replacement diet is the best personal weight loss program for you.

High-protein, low-carb diets

High-protein, low-carb diets replace starches and sugar with lean protein. Cutting carbs and sugar works because it tricks your body into burning fat for energy, which causes weight loss. Some of the most popular low-carb diet plans include Atkins, South Beach Diet, The Dukan Diet, FODMAP, paleo and keto weight loss programs. Diet plan reviews typically indicate that carbohydrate-restricted diets can be very effective for short-term weight loss, but it can be difficult to sustain long-term results using them.

Low-carb, high-protein foods

Chicken
Salmon
Avocado
Eggs
Leafy green veggies
Nuts
Seeds
Peas
Green yogurt
Protein bars

Foods to avoid

Processed meats
Grains
Pasta
Legumes
Cereal
Corn
Potatoes
Bananas
Beer
Juice
Soda

What diet advocates think: Diet plans low in carbohydrates and high in protein are excellent for people who want to change their overall eating habits. Eating high-protein foods also protects against muscle loss and increases your metabolic rate, which in turn increases calories burned. According to a 2018 obesity treatment study, side effects of a low-carb diet can include halitosis, headache and constipation.

Low-fat, low-calorie diets

Most low-fat, low-calorie dieters eat 800 to 1,200 calories per day and limit dietary fat to fewer than 50 grams. Some low-fat diet plans completely eliminate trans fats as well. Popular low-calorie and low-fat diet plans include Dietary Approaches to Stop Hypertension (DASH), Ornish, Health Management Resources (HMR), WW, Volumetrics and The Biggest Loser diets.

Low-fat, low-cal foods

Lean meats
Whole grains
Fruits
Fish
Mushrooms
Broccoli
Asparagus
Apples
Low-fat dairy
Eggs
Beans
Legumes
Oats

Foods to avoid

Oils
Butter
Mayonnaise
Fatty meats
Cheese
Chocolate
Packaged sweets
Fast food
White bread
Peanut butter
Flavored yogurt
Fruit juices
Alcohol

What diet advocates think: Some weight loss studies indicate that low-fat diets are less effective for rapid weight loss than low-carb diets. Ultra low-calorie diet plans can leave you feeling uncomfortably hungry most of the time, plus “low-fat” snacks are often full of sugars and refined carbohydrates. Never attempt an extremely low-calorie diet without consulting your doctor — there are serious health risks if you eat fewer than 800 calories per day.

Plant-based diets

Plant-based diet programs for weight loss encourage vegetarian and vegan meal plans. Some of the healthiest weight loss plans are plant-based diets that include raw, organic and whole foods and avoid animal products. Diet plan reviews are favorable for the Pritikin diet, macrobiotic diet, Eco-Atkins diet and Engine 2 diet. Many of the best weight loss programs, like Diet-to-Go, Nutrisystem and WW, offer vegetarian-friendly meal delivery for weight loss as well.

Plant-based foods

Fresh fruit
Green veggies
Eggplant
Mushrooms
Whole grains
Uncooked grains
Beans
Nuts and nut butters
Seeds
Coconut oil
Legumes
Tofu, seitan and tempeh
Non-dairy milk substitutes

Foods to avoid

Meats
Fish
Milk
Cheese
Alcohol
Prepackaged snacks
Processed foods
White bread
Baked goods
Starchy vegetables
Sugary drinks
Animal products

What diet advocates think: Plant-based diets require more effort and planning than many other options but are overall effective. Be aware, however, that it’s easy to overload on carbs, which won’t help with weight loss. Iron from plant-based foods is harder to absorb, so a vegan or vegetarian plan may not be a good option for dieters who are already at risk of anemia.

Cleanse diets

Cleanse diets, sometimes called detox diets, are short-term, restrictive weight loss plans. Some cleanse diets emphasize nutrient-rich foods, while others replace meals with liquids and herbal supplements. The all-natural weight loss program Whole30 is a cleanse diet that replaces all sugar, dairy, grains and alcohol with fruits, vegetables and lean protein. Juice cleanse diet programs for weight loss, such as the Master Cleanse or lemonade diet, replace all meals with liquids and herbal supplements.

Cleanse diet foods and drinks

Organic vegetables
Unsweetened fruit juice
Herbal teas
Unrefined oils
Plant-based milks
Chia seeds

What to avoid

Processed foods
Sugar
Soy
Wheat
Gluten
Alcohol
Animal products

What diet advocates think: Cleanse diets can support fat loss in the short term. Still, no studies prove these diets work for weight management or even removing toxins from the body, according to the National Center for Complementary and Integrative Health. Take caution with cleanse diet programs and be aware that unpasteurized juices and detox supplements could be harmful to your health.

Meal replacement diets

Many of the easiest weight loss programs rely on meal replacements. Meal replacement diets work by replacing one or two meals each day with low-calorie, nutrient-rich shakes and bars. Many meal replacements are supplemented with vitamins and minerals to burn fat. Meal replacement diets like Nutrisystem, Medifast and Jenny Craig provide many options for replacement shakes and bars as well as prepackaged meals for weight loss.

Meal replacement foods

Plant-based protein
Lean meats
Frozen vegetables
Dried fruits
Oats
Seeds
Nuts
Supplemental minerals

What to avoid

Sugar
Artificial sweeteners
Corn syrup
Corn maltodextrin
Chemical preservatives

What diet advocates think: Meal replacements are a convenient weight loss tool for busy professionals who don’t have time to plan out every healthy meal, and studies show they are effective for temporary weight loss. When comparing meal replacement labels, look for options with at least 10 grams of protein and 4 grams of fiber per serving. Avoid meal replacement options with more than 400 calories or more than 4 grams of added sugar and saturated fat.

How to choose a weight loss program

When choosing a weight loss program, think about times in the past you successfully completed a goal and what motivated you. As you compare weight loss plans, ask yourself if you want the flexibility of cooking your own meals or the convenience of a prepackaged meal delivery plan. The best weight loss program provides motivation, long-term support and safe diet plans that work with foods you enjoy for a fair price.

To find the best weight loss plan for you, follow these steps:

Find diet plans that work: Find a program that requires you to follow a weight loss meal plan while keeping track of the foods you eat and how much you exercise. Avoid weight loss programs that seem too good to be true, because they probably are. According to the Federal Trade Commission, some red flags include promises to cut weight without exercise, guaranteed weight loss in a specific area of your body and claims that you can eat as much of whatever you want.
Consider dietary preferences or restrictions: Think about whether the foods on a given diet are things that you generally enjoy. If you hate eating greens, you won’t like a diet filled with salads — but if you have a sweet tooth, a diet that substitutes milkshakes in place of meals might be exactly your speed. Those with food allergies or sensitivities could find restrictive diet plans difficult or impossible to follow. Some of the best weight loss food plans ship vegan or diabetic-friendly options meals straight to your door, while others require you to shop for very particular ingredients.
Think about what will motivate you to lose weight: Every person has different motivations for success. Think about how you have met other important goals or quit bad habits in the past. Would you be more likely to succeed using social media, in-person meetings or expert counseling using text messaging, phone calls or email? Research shows that social support, whether in person or online, helps people lose weight.
The best diet program to lose weight incorporates ongoing support to help keep weight off. Some plans emphasize quick upfront results, but maintaining fat loss is just as important as losing it. Pick a plan that provides the tools and strategies you need to stay lean for the long haul, such as Jenny Craig, Nutrisystem or WW.
Select a diet plan that’s healthy for your budget: The cost of weight loss programs varies depending on whether food is included. Programs that regularly ship prepackaged meals for you to prepare at home can cost more than $1,000 per month. More affordable weight loss programs cost a little as $5 to $10 per month but require you to do your own grocery shopping. Find a program that delivers the results you want without straining your wallet.

Best weight loss programs for women

About 2 in 3 women are overweight or have obesity.

Dieting is difficult for everyone, but women can feel like the odds are stacked against them. New moms often struggle with weight after pregnancy, and the lack of sleep doesn't help. Busy professionals have limited time to spend on elaborate meal plans. Since people’s metabolisms slow with age, it’s even harder for post-menopausal women to lose weight.

Most effective programs for losing weight are flexible because they were designed with busy, successful women in mind. An effective weight loss program for women maximizes your dieting efforts and keeps you on track toward your goal.

Many women have success with natural weight loss programs like WW, DASH, The Mayo Clinic or low-fat, low-calorie diets like Nutrisystem and Jenny Craig. More restrictive diets, such as keto, get results but are difficult for some to maintain over time.

Best weight loss programs for men

About 3 in 4 men are overweight or have obesity.

The good news is that men lose weight faster than women because their higher oxygen intake and testosterone levels allow for easier muscle gains and fat loss.

Low-carb, high-protein is the best diet to lose weight for men who want quick results. Keto and paleo diets are popular, but sustainable results vary. Some of the best men’s weight loss programs for long-term weight loss maintenance are also marketed to women. Jenny Craig, WW, Nutrisystem, Medifast and Diet-to-Go provide customizable meal plans with personal coaching that are effective for men and women.

Most experts don’t advise programs for losing weight that eliminate carbohydrates and dietary fat. Instead, look for a good balance of lean protein, slow-burning carbs and healthy fats to find the most effective men’s weight loss program.

Research shows that finding the best weight loss program for men isn’t that different from finding one for women. The best weight loss diet for men and women who want long-term results is a balanced one. Balanced diet plans like the DASH, Mediterranean and The Biggest Loser diets don’t restrict any specific food but encourage dieters to make smart decisions that lead them to healthy weight loss.

What is the best way to lose weight?

The most tried-and-true weight-loss tactics are reducing calories and extending workouts. Try these and 30+ more tips to lose weight fast.

Replace sugars and starches with lean proteins and vegetables

Switching to a high-protein diet boosts your metabolism and reduces food cravings, which helps you feel full throughout the day. Plus, calorie-counting is less important when you eat fewer carbs. To burn fat fast, opt for mostly healthy fats, lean proteins and slow-burning carbs.

Healthy fats: Plant-based oils (olive, soybean, vegetable and walnut oils), avocados, seeds, nuts and nut butters
Lean protein: Grilled white meat (lean pork, chicken and turkey breast), fish, eggs, tofu, Greek yogurt, low-fat cottage cheese, beans, protein shakes and meal replacement bars
Slow-burning carbohydrates: Apples, bananas, cauliflower, whole grain pasta, whole wheat couscous and eggplant

Drink eight to 10 glasses of water each day

Most drinks that aren’t plain water are just empty calories. You should cut soda, juice and milk from your diet and stick to zero-calorie water. The benefits of drinking water for weight loss include less bloating, avoiding dehydration and reducing thirst, which often leads to mistaken hunger. Diet apps and programs for losing weight make it easier to track how much water you drink each day.

Make exercise part of your daily routine

Even regular 15-minute walks or jogs through your neighborhood help speed up weight loss. Try to find ways to exercise when you’re not at the gym — take the stairs instead of the elevator or park far from the front door when out shopping. If you already exercise, you can add time to your routine or adjust it to include an extra day of training.

Get a full seven to eight hours of sleep each night

Sleep deprivation kills your will to exercise and drives you to eat quick pick-me-up foods that boost energy with fat-causing carbs and sugars. Try going to bed 15 minutes earlier every night until you’re getting a full seven to eight hours of sleep.

Try intermittent fasting for weight loss

Occasional fasting forces your body to tap into fat storages. You can eat your regular diet most of the time and drastically reduce your intake part of the time. The 5:2 diet is a popular intermittent fasting diet that suggests eating regularly for five days of the week and eating fewer than 500 calories for two days of the week. The 16:8 diet is similar, but you choose an 8-hour window when you can eat healthy meals and snacks while fasting (and sleeping) the remaining 16 hours of the day.

Benefits of losing weight

If you’re currently overweight or obese, losing 5% or more of your body weight comes with a variety of benefits. Healthy weight loss programs emphasize lifestyle changes that help you burn fat more easily, which in turn benefits your body, mind and bank account.

Even losing just 10 to 20 pounds benefits your physical and mental health. You’ll live longer by maintaining a healthy weight, which reduces the risk of depression, anxiety and certain diseases. Dieters reap even more benefits when their weight loss program emphasizes healthy habits like quality sleep and drinking more water.

Health benefits of losing weight

Weight loss is linked to healthier skin and hair. Plus, you’ll sweat less. Additional physical benefits of losing weight include:

Reduced risk of heart disease, hypertension, stroke, Type 2 diabetes and some cancers
Reduced symptoms of osteoarthritis and sleep apnea
Improved mobility and fertility
Lower blood pressure
Less acid reflux
Less back and joint pain
Less severe allergies

Psychological benefits of weight loss

Being overweight can cloud the way you see yourself and the world. The benefits of weight loss and exercise include better self-esteem, more confidence and a better sex life. Losing weight can also benefit your taste buds — many successful dieters report foods taste better than they did before. Additional mental health and emotional benefits of losing weight include:

Increased vitality
Reduced stress
Reduced depressive symptoms
Improved body image and hormonal balance
Better memory

Financial benefits of weight loss

You’ll save money on future health care bills thanks to improved blood pressure, cholesterol and triglyceride levels. Most successful dieters also cook at home more often, which reduces the amount of money they spend eating out.

Lower medical bills
Lower transportation costs
Fewer prescription medications
Less eating out

Weight loss questions and answers

How can I lose 10 pounds in seven days?

If you already have a significant amount of weight to lose (50 pounds or more), you can lose up to 10 pounds in one week by following strict dietary guidelines and a cardio workout regimen. Drastic changes in your regular lifestyle, specifically aerobic exercise and a sharp decrease in calories, causes fast weight loss. The hard part is maintaining your weight loss.

The Centers for Disease Control and Prevention reports weight loss is best obtained slowly and steadily with a program that includes physical activity. Losing 1 to 3 pounds per week is a healthy weight loss goal for most people.

What foods help burn belly fat?

If you want to lose belly fat fast, eliminate all trans fats and alcohol from your diet and add bananas, yogurt, berries, oatmeal, green tea, almonds, apple cider vinegar and whole grains to your shopping list. Foods rich in potassium and probiotics stop the blood sugar spikes that tell your body to store fat around your midsection.

What is the cheapest diet program?

Vegetarian and low-calorie diet programs are usually, but not always, the cheapest. The cost of your diet program depends on the level of support and guidance offered and whether the program includes meals and snacks. For example, you can start WW for $3 per week, but you have to do your own grocery shopping. On the low end of programs that provide food, Nutrisystem provides meal delivery and support for around $10 per day. On the high end, The Zone Diet costs about $50 per day for meal delivery.

What is the best online weight loss program?

Noom, Beachbody and Lose it! are three of the best online weight loss programs. Dieters on other weight loss programs, like WW and Nutrisystem, use apps to log meals, track exercise, access healthy meal plans and find dieting support. For more about the best online weight loss programs, read our picks for the best weight loss apps.

What diet pill really works?

Diet pills that work contain active ingredients intended to burn fat, decrease appetite and reduce fat absorption. Fast weight loss pills typically include caffeine, green tea extracts and medically proven weight loss supplements like pyruvate and glucomannan. Some of the best diet pills right now also contain garcinia cambogia.

Caffeine and green tea extract help increase metabolism, pyruvate may help decrease body fat and glucomannan is a natural dietary fiber that helps feed the good bacteria in your intestines. Garcinia cambogia contains hydroxycitric acid (HCA). Studies show HCA inhibits fat-producing enzymes in some animals, but evidence that garcinia cambogia is effective for weight loss remains inconclusive.

Side effects of prescription and over-the-counter diet pills can be severe, especially if you’re sensitive to caffeine. The most common side effects of diet pills include digestive problems, diarrhea, blurred vision, headache, nausea, insomnia, anxiety and irritability.

How can a beginner start losing weight?

The best weight loss plan for beginners combines a low-calorie or low-carb diet with daily exercise. For more information, check out 31 weight loss tips to help beginning dieters lose weight fast.

Are meal replacement shakes good for weight loss?

As with many foods, there are healthy meal replacement shakes for weight loss and others that make promises they don’t fulfill. Some meal replacement shakes that promise “pure protein” have the same nutritional value as a milkshake, so it’s important to research options before purchasing.

Rather than counting calories, check the actual ingredients to see if the formula includes real food and enough fiber. Skip meal replacement shakes for weight loss that include artificial sweeteners and preservatives. For more about meal replacement diets, read about our top picks for the best meal replacement shakes.

Keep in mind that the best times for meal replacement shakes for weight loss are hurried mornings when you’d otherwise skip breakfast and when you need a quick meal before exercising.

How long does it take to lose weight?

Most people can expect about 2 to 3 pounds of healthy weight loss a week through dieting and regular exercise. On average, a dieter needs to lose 8 or 9 pounds before other people begin to notice results, which takes closer to a month.

What is a fad diet?

A fad diet is one that gains rapid popularity for a time and then falls out of fashion. Most fad diets are food-specific or revolve around a gimmick. For example, the cabbage soup diet requires you to eat only cabbage soup for each meal for a week. The paleo diet, which limits what you can eat to what was available during the Paleolithic Period, is also considered a fad diet. More recently, diet advocates have also classified the alkaline diet, which is based on the hypothesis that the acidity of foods affects your body’s pH balance and that a higher pH leads to weight loss, as a fad diet.
