We pulled the top 14 of the best commercial diets (marketed to the public for profit) and the top 12 of the best diets overall. We also threw five of the most popular diet apps into the mix. Since these are largely tracking devices that don’t espouse unique eating habits, they don’t appear to meet US News’ definition of diet, but are still potentially effective weight loss tools.
Losing weight is no small feat—it often requires a complete lifestyle overhaul, and with so much information out there, it can be tough to know what strategy might work for you. And to top it all off, all the weight loss myths that just will not die threaten to throw you off track. That's why it's helpful to know what has worked for real people—in their own words. Here, we've gathered advice from 28 women who have lost between 26 and 174 pounds—and kept that weight off for good.
If you want to lose body fat, going low carb – or even ketogenic – can help you program your body to burn fat for its main fuel. By reducing calorie consumption after becoming fat-adapted, you can focus on fueling with fibrous vegetables and protein, reduce fat intake, and your body will use stored body fat for energy. With consistency and dedication, this can result in rapid fat loss.
“There are many diet plans on the market today that promote good health,” says Emily Kyle, RDN, who is in private practice in Rochester, New York. “The key is finding one that does not cause you stress or agony.” Ask yourself questions such as: Would the diet guidelines make you happy? Anxious? Stressed? Are you able to follow them long term? “Factors such as enjoyment, flexibility, and longevity should be strongly considered,” adds Kyle.

“Intermittent fasting can be really challenging if you have an ever-changing schedule,” adds Hultin. “If you're traveling and crossing time zones, it could be very difficult to follow. It might be best for people with more stability in their lives.” Intermittent fasting isn’t safe for people with type 2 diabetes, children, pregnant or lactating women, or anyone with a history of an eating disorder.
Grazing is a surprisingly good idea because it helps you avoid metabolic slowdown. "Your body will be tricked into thinking it's constantly eating, so it will never slow your metabolism down," explains Bauer. Aim for five small meals (200 to 500 calories) a day rather than three large ones. Also try not to go more than four hours without eating — if you eat breakfast at 7am, for example, have a snack at 10am, lunch at noon, another snack at 3pm and dinner at 7pm.
If the diet is a quick fix rather than one that promotes lasting lifestyle changes, this could pose a problem. In particular, extreme diets that promise big weight loss up front aren’t always sustainable — and you may end up overeating or even binge eating if you feel deprived. “Consider if the diet’s habits are ones you can continue throughout your lifetime, not just 21 or 30 days,” says Angie Asche, RD, a sports dietitian in Lincoln, Nebraska.
Good sleep hygiene can help. “Our ancestors needed to sleep when it was dark, quiet, and cool, Gillespie says. “That meant it was safe.” Despite technological advancements like heat and air conditioning, our bodies still crave those cave-like conditions. Draw the blinds, use a white noise generator, and keep the thermostat set between 63 and 68 degrees.

The most important consideration of any diet is finding one that you can stick with for the long haul. While many diets promise that you'll quickly shed pounds in the beginning, the truth is that reining in your eating will almost always result in quick, initial weight loss regardless of what program you decide to try. The trick is to find a program that -- after that first couple of weeks -- you can adhere to as your weight loss slows to more realistic levels. Experts say that people who make diets a lifestyle rather than just a "diet," while setting a goal of losing a pound or so a week, are more apt to keep the weight off over the long term.
●Halt bad eating habits. Before you cave to the crave, hit the pause button, recommends Pamela Peeke, author of the bestseller “The Hunger Fix: The Three Stage Detox and Recovery Plan for Overeating and Food Addiction.” Ask yourself: “Am I hungry? Angry? Anxious? Lonely? Tired?” Get in touch with your emotions and ask, “Am I’m emotional right now? Am I about to knee-jerk into overeating?”
In addition, the healthy habits and kinds of foods recommended on the Mayo Clinic Diet — including lots of vegetables, fruits, whole grains, nuts, beans, fish and healthy fats — can further reduce your risk of certain health conditions. The Mayo Clinic Diet is meant to be positive, practical, sustainable and enjoyable, so you can enjoy a happier, healthier life over the long term.

When you’re trying to flatten your stomach, reducing your intake of artificial sweeteners, sugar alcohols and sugar substitutes can help, notes Shay Kostabi, Master Trainer and Creative Director for ReXist360 Resistance Training Systems. “These sneaky devils can wreak havoc on your whole digestive system, which can cause weight gain and bloating. To nix bloating in the long run, Kostabi suggests eliminating the sweeteners altogether. They can be hiding in everything from protein bars to gum, so be sure to read labels carefully. For immediate deflation, she suggests increasing your water intake. Though any H20 will get the job done, she’s a big fan of Essentia, an electrolyte-enhanced water that comes in a BPA-free bottle.

So it’s no wonder that losing weight and getting in shape are among the most popular resolutions year over year, because so many people can’t keep them; 80% of New Year’s resolutions fail by February. So Moneyish spoke with several leaders in the field of obesity research and prevention who have reviewed the science surrounding weight gain and loss to explain what to eat and avoid; how much exercise you need and which workouts work best; as well as their tips for making these moves a part of your new, well-balanced life in the New Year.
I have been on the Wild Diet for a week now and have lost 11.4 lbs. I know a lot of it is water weight, but I will take it. When I first started, I thought the low carbs would be hard, because I’m a carb junky. But I can say, I have not carved carbs on this plan! I also have more energy and feel awesome! I can’t wait to see how my body & mind changes in the following weeks. Thank you for sharing this program!
If you’re having trouble getting to bed, these 20 sleep strategies can help. To help stick to these strategies, consider these sleep tips your weight loss tips as well. Shutting off electronics an hour before bedtime, limiting caffeine intake in the afternoons, avoiding simple carbs in the evenings and journaling can all help you unwind so you get enough rest. You can also consider natural sleep aids to boost your ability to fall asleep and sleep soundly.

"Anytime you’re stressed, you probably go for food," Dr. Seltzer says. (Have we met?!) That’s because cortisol, the stress hormone, stokes your appetite for sugary, fatty foods. No wonder it’s associated with higher body weight, according to a 2007 Obesity study that quantified chronic stress exposure by looking at cortisol concentrations in more than 2,000 adults’ hair.
Tip #1: Eat nutrient-dense foods daily, like green smoothies, hearty salads, and bone broth. Green smoothies should be made of primarily leafy greens that are packed with vitamins and minerals, filling fiber, and raw food enzymes to aid digestion (add Future Greens for a boost to the flavor and nutrition). And the low, slow cooking of the bones of pasture-raised animals to make bone broth draws out the collagen, marrow, and other healing elements from the bones, including amino acids, minerals, glycine, and gelatin—which helps heal the gut, provide nutrients, and reduce inflammation.
People often cut out dairy when dieting, but cow’s milk has a lot of the nutrients that are essential to fat burning, including vitamin D and calcium. It’s also a great source of protein, which you need to build lean muscle, which is why experts say milk is a better post-workout drink than other beverages. Some research suggests that chugging moo juice after exercise results in more muscle gain and fat loss than drinking energy drinks. Find out more calcium-rich foods that are natural fat-burners.
Most people think of cardio as a weight loss all-star, but you don’t need to spend all day on the treadmill to slim down. In fact, you might want to concentrate your efforts in the weight room. Muscle is metabolically active tissue, which means that it burns calories even when you’re not lifting; your body burns calories just to maintain muscle, so the more of it you have, the more calories you torch. You lose muscle mass naturally as you age, a process known as sarcopenia, which is why losing weight tends to get tougher the older you get. One study found that just ten weeks of resistance training increased resting metabolic rate (the number of calories your body burns when you’re not doing anything) by 7 percent. Check out this simple strength training routine that challenges your entire body.
To figure out how many calories you burn a day, calculate your resting metabolic rate—the number of calories you burn daily doing routine activities, not including formal exercise—using this formula: RMR = bodyweight (in lbs) x 13. Next, determine how many calories you burn through exercise—a half-hour of moderate-intensity aerobic exercise burns around 350 calories in the average man, and a half-hour of lifting burns around 200. Add your RMR to the calories you burn in the gym, and keep your daily calorie consumption below that total.
"I've worked out regularly for over three years now and for the first two and a half years, my weight didn't move," says Tara Bird, 38. "It wasn't until I consistently started tracking everything that I ate that I saw the scale start to go down. I figured out what my maintenance calories were and created a deficit of 300 to 400 calories. Progress has been slow, but I've lost 23 pounds in the last year. Ideally, I would like to lose another 15 pounds, but I'm happy with my progress. Slow and steady!"

Weight Watchers has been around for over five decades, and they have recently revamped their diet program to include a stronger emphasis on physical activity as well. The modern-day Weight Watchers is more of a lifestyle overhaul than a strict diet plan, and that’s what makes it so successful. People looking to change their lifestyles permanently benefit from the extensive resources and the support of a large online community.
We all get by with a little help from our friends, and this is especially true of people who have lost weight and kept it off. In one study among women who went through a 12-week weight loss program, 74 percent of them maintained their loss or lost more in the three years after the program ended. Those who reported having a support system around eating well were more likely to keep the weight off. (Support around exercise didn’t seem to matter.) Another study found that the type of support you receive matters, too. Your friend who’s cheering you on isn’t likely to be as helpful as your friend who will pass on the fries when you’re trying to eat well. When you’re going out to eat, join friends who will support your healthy eating goals and go to a museum or movie with those who are less likely to be in it with you. Your pals who are in the trenches with you are more likely to hold you accountable, and that’s going to help you in the long run.

Because HIIT is harder on your body than steady-state cardio, you will require adequate rest to gain the most benefits, so don't feel bad for taking a day off. A good rule of thumb is to decrease the number of days you exercise as the load gets heavier. For example, HIIT using just your body weight can be done 3-5 days a week for 20-30 minute sessions.


Many of our best-rated weight loss programs have tracking software available online, as well as mobile apps, or even paper-tracking programs for those who prefer hard-copy journaling. Other programs or diets may not have dedicated websites, but there are a wealth of free calorie and activity tracking websites that offer community support, recipes and even free exercise videos.
Sometimes, you might need an external motivator—like a race or a competition—to keep you on track. After a slow start to her slimdown, Maribel Contreras decided to sign up for a 12-week body transformation contest at her gym. She swapped out her fast-food trips for healthy homemade meals and revved up her workouts, which ultimately helped her win the competition. She now maintains a 77-pounds-lighter frame. 
Weight loss occurs when the body is expending more energy in work and metabolism than it is absorbing from food or other nutrients. It will then use stored reserves from fat or muscle, gradually leading to weight loss. For athletes seeking to improve performance or to meet required weight classification for participation in a sport, it is not uncommon to seek additional weight loss even if they are already at their ideal body weight. Others may be driven to lose weight to achieve an appearance they consider more attractive. However, being underweight is associated with health risks such as difficulty fighting off infection, osteoporosis, decreased muscle strength, trouble regulating body temperature and even increased risk of death.[3]
Some diet plans, such as the MIND diet and the DASH diet, are meant to focus on certain areas of health — and weight loss may be a bonus. Others are created with weight loss as a primary goal. “It is important to remember that we are all very unique individuals,” says Kyle. “We all have different states of health and different lifestyles, which could affect what diet plan is best for us. That means that you should not be considering what is working for your friends or family members — and instead should pay attention to what works for you individually.”
To encourage ketone production, the amount of insulin in your bloodstream must be low. The lower your insulin, the higher your ketone production. And when you have a well-controlled, sufficiently large amount of ketones in your blood, it’s basically proof that your insulin is very low – and therefore, that you’re enjoying the maximum effect of your low-carbohydrate diet. That’s what’s called optimal ketosis.
Given that all participants in the study were overweight and “healthy”, what was not studied, and could have been very useful, was what was the impact of the two diets on participants’ blood sugars (HbA1c), insulin levels, and on some measure of inflammation. It is possible that there could have been little difference in weight loss between the two diets but big differences in the impact on risk factors related to diabetes.

Aside from offering customizable diet plans, some companies offer consultants and diet experts for developing personalized diet programs for their clients. These experts help formulate diet plans or recommend food substitutes for people with health conditions such as diabetes for example. They could also help you come up with a diet program that is best suited for your budget.

Diet drinks can have a kind of mental placebo effect, making you feel like it’s OK to indulge because you “saved” all those liquid calories. And research shows that your body may be tricked too: People who chug one or more diet drinks a day are more likely to be overweight—not less. Can the soft drinks, whether the sugar in them is real or a substitute. Find out 30 other tiny diet changes that can help you lose weight.
Other diabetes medications. Insulin-releasing tablets (e.g. sulphonylureas) often lead to weight gain. These include: Minodiab, Euglucon, Daonil, and Glibenclamide. Tablets like Avandia, Actos, Starlix and NovoNorm also encourage weight gain. But not Metformin. The newer drugs Victoza and Byetta (injectable) often lead to weight loss, but possible long-term side effects are still unknown. More on diabetes
Similarly, just because snacks like blue chips don’t look like the greasy potato chips you know to avoid, don’t assume they’re a healthier option. “Yes, blue corn contains the antioxidant anthocyanin,” explains certified culinary nutritionist Trudy Stone. “However, much of the good stuff gets baked away during the process of creating the chips that very little nutritional value is left—leaving them not much healthier than your typical tortilla chip.”
Long-term weight loss appears to be more of a function of lifestyle choices than specific food choices. One study on people in the National Weight Control Registry, a large group of people who have lost significant amounts of weight and kept it off for at least five years, found that key weight maintenance behaviors include a consistent diet pattern, not skipping breakfast, and exercising at least an hour per day (5).
13. If you want to lose fat and build a tighter tush, do your squats and lunges first. You see the best results in the muscles you train early in your workout because you’re able to hammer out the most reps and perform them with stellar form, compared to when your body is fatigued later on, suggests a study in the Journal of Sports Science and Medicine.
It has a strong emphasis on consistent exercise and encourages dedication to daily workouts. You can also log physical activities such as sports participation, walking and even cleaning. By browsing activities in the program’s fitness tracker and logging how much time you spent exercising, you can estimate and record the calories you’ve burned. Michaels promotes a diet high in protein and low in fat and carbohydrates. While her program provides instruction on healthy eating habits, it doesn’t give you much information about portion sizes or ingredient substitutions. However, it does provide a detailed weekly meal plan, and complete nutritional information is included with every recipe. For support in achieving your goals, the program’s online member community includes message boards and blogs where you can interact with other participants.
Most people who want to lose weight have more than 12 pounds to lose. That’s why even the best weight loss drug in the world can only be an optional complement to other treatment. That’s why this piece of advice is number 18 out of 18. It may be a helpful addition for some people, but the advice higher on the list is what can make the biggest difference, by far.
The Mayo Clinic Diet provides practical and realistic ideas for including more physical activity and exercise throughout your day — as well as finding a plan that works for you. The diet recommends getting at least 30 minutes of exercise every day and even more exercise for further health benefits and weight loss. The diet also emphasizes moving more throughout the day, such as taking the stairs instead of an elevator.
Many patients will be in pain and have a loss of appetite after surgery.[26] Part of the body's response to surgery is to direct energy to wound healing, which increases the body's overall energy requirements.[26] Surgery affects nutritional status indirectly, particularly during the recovery period, as it can interfere with wound healing and other aspects of recovery.[26][30] Surgery directly affects nutritional status if a procedure permanently alters the digestive system.[26] Enteral nutrition (tube feeding) is often needed.[26] However a policy of 'nil by mouth' for all gastrointestinal surgery has not been shown to benefit, with some suggestion it might hinder recovery.[38][needs update]

Noom: To help you figure out how to prioritize or limit food items, Noom offers color coding. Green means go for it — “green” foods include veggies and grains, and these should make up a solid 30% of your diet. “Yellow” foods include lean meats and starches, and these can account for a touch more — 45%. “Red” foods (red meats and sweets) should appear less than both green and yellow, around 25%. When you log meals, the app lets you know how well you’re aligning with these proportions.

The South Beach Diet is also considered low-carb, but it's not as restrictive as Atkins in its later phases. In fact, even in the early phases of the South Beach Diet, small servings of complex, non-vegetable carbs are allowed. South Beach earns high praise for weight loss and as an overall healthy way of eating, but gets panned for its complicated meal plans and time-consuming recipes by both users and experts. The ingredients in its recipes can jack up your grocery bill as well. Still, it's popular for those who love to cook, or prefer meals that aren't just a hunk of meat and a vegetable (or two).


This popular plan recently underwent a rebranding to create a more balanced program, changing its four-phase approach with the help of a science advisory board. The Atkins Diet is still low-carb, but you won't be chowing down on steak and eggs all the time to promote weight loss. Lean protein is still key, but there's more of a spotlight on fiber, fruit, vegetables, and healthy fats.

The secret to a slimmer stomach in no time? A whole lot of fiber in your diet. Although many people are loath to add carbs to their diet when they’re trying to lose weight, adding the right, fiber-rich ones can have inches off your belly in a hurry. In fact, researchers at Wake Forest Baptist Medical Center found that every 10-gram daily increase in soluble fiber was associated with a 3.7 percent decrease in dangerous visceral fat over five years. Those who were active got even leaner, shaving off twice that much fat in the same amount of time. To start ditching that extra belly fat today, add the 30 Best Foods For Fiber to your menu!

It’s bad for every part of your body.  Your body is actually breaking down, your relationships suffer, your brain doesn’t work right, your joints hurt, you lose muscle, and you just don’t look good in the mirror.  Conventional wisdom says you should start cutting fat and calories and run on a treadmill for an hour a day. Then you’re made to feel as if it’s your fault because their advice doesn’t work.
Anecdotally, many people say they feel great on the Paleo diet -- losing weight and lowering health markers such as blood pressure and cholesterol. However, like most programs, many simply don't stick with this way of eating over the long term -- they keep lapsing and going back -- the same issue we see with all eating plans. Again, there is no formal "Paleo" diet, but there are plenty of books and online resources for anyone interested in exploring the idea.
The Mayo Clinic Diet provides practical and realistic ideas for including more physical activity and exercise throughout your day — as well as finding a plan that works for you. The diet recommends getting at least 30 minutes of exercise every day and even more exercise for further health benefits and weight loss. The diet also emphasizes moving more throughout the day, such as taking the stairs instead of an elevator.
There are many ways to do intermittent fasting — ranging from fasting for a number of hours each day up to an entire 24-hour fasting period one or two times a week. “If you're trying to kick a habit like eating late into the night, then stopping eating earlier in the evening and fasting overnight could be beneficial for you,” says Hultin. “There are many types of intermittent fasting, so ensuring you pick one that works for you and your lifestyle is important.”
While they won’t necessarily help with the fat burning process itself, juices may indirectly benefit your weight-loss efforts.  Replace any soft drinks or other processed, sugary beverages with 100% natural, no-sugar-added juices.  Vegetable, cranberry, pomegranate, and acai are some great choices that also offer a variety of auxiliary health benefits.  Just remember to watch your calorie intake!
For even more impressive effects on body composition: aim for exercise forms which elicit a positive hormonal response. This means lifting really heavy things (strength training), or interval training. Such exercise increases levels of the sex hormone testosterone (primarily in men) as well as growth hormone. Not only do greater levels of these hormones increase your muscle mass, but they also decrease your visceral fat (belly fat) in the long term.

Americans are getting less sleep than ever these days and it’s taking a toll on our health—most visibly on our waistlines. Losing just 30 minutes of sleep per night can make you gain weight, according to a study done by the Endocrine Society. Worse, that weight is more likely to go straight to your tummy. Instead, the researchers found, the best sleep cycle is one that follows your natural circadian rhythms, which means sleeping and waking around the same time as the sun. Here are the 7 ways to banish belly bloat in your sleep.
