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.
“Do what you can instead of quitting when you can't be ‘perfect,’” Fear says. As if there’s such a thing as “perfect.” After all, research suggests that perfectionism surrounding food and weight, especially coupled with body dissatisfaction, contribute to disordered eating and even obesity in women. Researchers note that perfectionism can contribute to poor self-esteem, dietary restraint, and binge eating.

Control Your Environments. Another simple strategy to help cut calories is to control your environment -- everything from stocking your kitchen with lots of healthy options to choosing the right restaurants. That means avoiding the temptation by staying away from all-you-can-eat restaurants. And when it comes to parties, "eat a healthy snack before so you won't be starving, and be selective when you fill your plate at the buffet," suggests Ward. Before going back for more food, wait at least 15 minutes and have a big glass of water.

Stop treating your kitchen like an all-night diner and you’ll stop seeing those unwanted pounds piling onto your frame, too. The results of a study published in Cell Metabolism found that mice who only had access to food during an eight-hour period stayed slim over the course of the study, while those who ate the same number of calories over a 16-hour period gained significantly more weight, particularly around their middle. When you’re finished with dinner at night, shut the fridge and don’t look back until morning — your belly will thank you. When you do head back to the kitchen in the A.M., make sure the 40 Things Healthy Cooks Always Have in Their Kitchen are there waiting for you.

“Patients can diet themselves down to any weight they put their minds to, but to maintain that weight, they need to actually enjoy the lifestyle that got them there,” writes Yoni Freedhoff, M.D., the medical director of the Bariatric Medical Institute in Ottawa, Canada, and Arya M. Sharma, M.D., Ph.D., the founder and Scientific Director of the Canadian Obesity Network, in Best Weight, a manual for clinicians who treat patients pursuing weight loss. “A patient’s best weight is therefore whatever weight they achieve while living the healthiest lifestyle they can truly enjoy.”

Ah, the über-popular “know your why” strategy. One Brown University study found that when people are motivated to lose weight for appearance and social reasons, they stick with their weight-loss habits for significantly less time than those who are motivated by their health. After all, these external motivators (like looking a certain way or fitting into a cultural ideal) aren’t going to get you going when you’re feeling down, have had a bad day, or are frustrated with a plateau, Albers says.

The HMR Program uses meal replacements – think low-calorie shakes, meals, nutrition bars and hot cereal – in phases, coaching from experts, physical activity and an emphasis on fruits and vegetables to help dieters shed pounds fast. While last year the diet shared the No. 1 ranking in this category with the Biggest Loser diet, this year it has the top spot to itself. "This diet makes it easy to lose weight fast and would likely be effective for someone who wants to lose weight for a specific event," one expert said. "However, as far as long-term healthy-habit-forming, this diet falls short" in part because dieters don't learn to make their own healthy food choices.
Sure, you certainly need to drink plenty of water to help expedite the process of ridding your body of excess sodium, you can (and should!) also consume high-water content foods. Reach for cucumbers, tomatoes, watermelon, asparagus, grapes, celery, artichokes, pineapple, and cranberries — all of which contain diuretic properties that will also help you stay full due to their higher fiber content.

If you’re already enjoying and eating foods high in fat along with protein, you might want to consider going on the keto diet. It’s been proven to be more effective at weight loss than a low-fat diet, and you’ll likely have an easy time transitioning to it. (9) Among my weight loss tips, going keto is the diet that produces the quickest results alongside significant health changes.


Instead, we've evaluated expert reviews, most notably those published annually at U.S. News and World Report. That publication consults medical professionals who, in turn, consult clinical studies as well as utilizing their own experience and expertise to make their recommendations. We then work our way down to dieter opinions posted on survey sites -- to identify the most nutritionally sound and sustainable weight loss programs. That includes diets, meal-delivery plans, diet books and free, online resources that will help you lose weight and keep it off over the long-term.
Known as the carb-hating diet, the South Beach diet is a weight-loss food plan centered around low-carbohydrate meals. It’s important to note that the South Beach Diet doesn’t forbid carbohydrates, unlike many fad diets out there, instead, this healthy weight-loss system understands the intrinsic benefits of healthy carbs and builds them into your meal plans to maximize those strengths for optimal health and weight loss.

It's no surprise that Dr. Dean Ornish's program is such a powerful tool for weight loss, considering its easy adaptability as a lasting lifestyle. The diet is mostly plant-based, keeps sodium intake in moderation, and limits coffee to a cup a day (two cups decaf) — so if you're looking to lose weight while keeping your java flow, you may want to consider another plan.
The idea is that the fasting induces mild stress to the cells in your body, helping them become better at coping with such stress and possibly helping your body grow stronger. The verdict is still out regarding the diet’s long-term effectiveness with weight loss, according to a review of preliminary animal research published in January 2017 in Behavioral Sciences. (17)

If you've been trying to eat healthy for a long time, you know how quickly you get sick of chicken breasts and broccoli. Break out of your diet rut with the Middle Eastern diet. It's based on the same principles as the Mediterranean diet but with more of an emphasis on plant-based foods and a different flavor profile. With all the tasty and healthy spices, you'll never get bored of making dinner and you'll get all the same heart-healthy benefits as its geographical cousin's diet.


WeightWatchers is one of the best known weight loss programs around. The reason it’s successful is that it’s often viewed as one of the easier programs to follow, helping you to change the way you think about and behave around food. Nothing is off limits, so you can still enjoy your favorite meals and snacks, even a drink of alcohol now and then, meaning...
Fruits like berries, cherries, apples, and oranges are high in quercetin, a natural compound that reduces inflammation in the belly. And if you put a bowl of the good stuff right where you can see it in your kitchen, you’re more likely to reach for it when you want a snack. These are the 10 reasons why apple cider vinegar is brilliant for slimming down.
Want a flatter stomach? Look in your glass—milk and soda are two major causes of tummy inflation. Approximately 65 percent of the human population has a reduced ability to digest lactose after infancy, which means that your glass of warm milk before bed may be the reason you wake up with too-tight pajamas. And when it comes to soda, both regular and diet are belly busters both from the sweeteners used and the carbonation. Try eliminating these from your diet and see if it helps flatten your tummy.
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.
That doesn't mean one type of eating has the edge, however. "I individualize eating plans to allow both men and women to enjoy their preferences for carbs or protein, providing they select the healthy versions," says Tallmadge, who is also a spokeswoman for the American Dietetic Association. Another difference Tallmadge sees in her practice is that women tend to be fairly knowledgeable about food and calories, while the men don't think much about nutrition.
Diet programs should not only be suited to a client’s health needs but also be attune with their budget. Aside from providing customizable menus, some diet programs also offer clients price-based menus. Some companies offer one-time diet plans as well as free trials. A money back guarantee is certainly a welcome for those who don’t find success with the diet program. Pricier diet programs don’t always translate to a successful and effective diet. The ultimate measure of an effective diet program is the client’s compliance with the recommended diet. 
"Order without looking at the menu. Almost every restaurant has the basics—veggies, grains, and protein. If you go in knowing what you want, I guarantee you'll be able to make a meal. If you're too uncomfortable to ask for what you need, tell a white lie: Say you're allergic. I know it's controversial to suggest this, but women in particular can really have trouble standing up for their own needs. So if you want the broccoli soup puréed without cream, tell the waiter you're lactose intolerant."
Grains get a bad rap when it comes to weight loss, but that's because refined grains (read: processed foods!) are linked to wider waists. 100% whole grains are bloat-busting superstars, however, as they're packed with minerals and de-puff by counter-balancing salt. Stick to brown rice, quinoa, wheat, barley, millet, farro, sorghum, and amaranth for the biggest benefits.
Eating patterns that restrict certain food groups can certainly help you lose weight, but many people find it hard to continue to eat that way forever. If you want to think of your diet like a relationship, you don’t want to be in an “it’s complicated” or “on-again, off-again” situation. You want to find your match — a meal plan you can feel content with for the long haul. That doesn’t mean you have to ditch all of your favorite foods for eternity. It’s okay to flirt with the foods that make you swoon, but you don’t want to settle down with them. When your healthy habits are solid, enjoying your favorite foods sometimes is no big deal.
Giancoli also recommends finding a diet that fits in with how you really live. She notes that if you enjoy going out to eat but try to commit to a diet that forbids you from ever going to a restaurant, you’re just going to cheat. “It’s not sustainable… You’re most likely going to have a healthier meal if you’re going to cook yourself, but you’re depriving yourself of that social interaction if you never go out.” To put it another way: Your eating practices shouldn’t isolate you or keep you from having fun.

Mindfulness matters. “If you slow down and stop just mindless eating, you often realize you don’t need to eat as much as you thought you did; you’re already full,” said Dr. Steinbaum.” Part of this is watching portion sizes, which have ballooned in restaurants over the past 40 years, leading adults to consume an average of 300 more calories per day now than they did in 1985. Did you know that one serving of bread is actually just one slice? Or one serving of pasta or rice is just half a cup? And a serving of cheese is only two ounces, or the size of a domino? You’re probably eating much more than you realized. “There have been multiple studies that see keeping a food journal is effective,” said Dr. Steinbaum. “When you start paying attention, you can really see what you’re doing.”
Eat more protein. Protein is required by the body to repair damaged cells and plays a vital role in growth and development.[3] But it can also play a role in weight loss. Diets high in protein tend to make people feel fuller, and when paired with a reduction in carbohydrate intake these diets can help with weight loss.[4] However, it's important to remember that not all sources of protein are good for you: red meat and full-fat dairy products, though high in protein, can also increase the risk of heart disease.[5] Good sources of protein include:[6]

Sure, ketchup is tasty, but it’s also a serious saboteur when it comes your weight loss efforts. Ketchup is loaded with sugar — up to four grams per tablespoon — and bears little nutritional resemblance to the fruit from which it’s derived. Luckily, swapping out your ketchup for salsa can help you shave off that belly fat fast. Fresh tomatoes, like those used in salsa, are loaded with lycopene, which a study conducted at China Medical University in Taiwan links to reductions in both overall fat and waist circumference. If you like your salsa spicy, all the better; the capsaicin in hot peppers, like jalapeños and chipotles, can boost your metabolism, too.
Don't banish certain foods. Don't tell yourself you'll never again eat your absolutely favorite peanut butter chocolate ice cream. Making all treats forbidden is sure to make you want them even more. The key to long-term success is making healthy choices most of the time. If you want a piece of cake at a party, go for it! But munch on the carrots rather than the chips to balance it out.
With this eating style, you’re looking at a lot of menu planning and preparation. A review published in August 2017 in Nutrients suggests the diet could lead to weight loss, but the Academy of Nutrition and Dietetics warns the plan could also cause certain nutrient deficiencies, such as in calcium and vitamin D. (3,4) And, therefore, according to an article published in the January–February 2016 issue of the Royal Australian College of General Practitioners, anyone at risk for osteoporosis should avoid it. (5)
Potassium, magnesium, and calcium can help to serve as a counter-balance for sodium. Foods that are rich in potassium include leafy greens, most "orange" foods (oranges, sweet potatoes, carrots, melon) bananas, tomatoes, and cruciferous veggies — especially cauliflower. Low-fat dairy, plus nuts, and seeds can also help give you a bloat-busting boost. They've also been linked to a whole host of additional health benefits, such as lowering blood pressure, controlling blood sugar, and reducing risk of chronic disease overall.
Popularized by the documentary Forks Over Knives, the Ornish diet is a low-fat, plant-based diet plan based on whole grains, vegetables, fruits, and legumes. It's based on a lacto-ovo style of vegetarianism, allowing only egg whites and nonfat dairy products. It's packed with vitamins, fiber, and lots of filling plants to keep you satiated. Some studies have shown it can reverse heart disease and have beneficial effects on other chronic health conditions. (BTW, there is a difference between a vegan diet and a plant-based diet.)
Of course, you want to get to the bottom of why you’re not feeling so hot. One study found that practicing relaxation techniques helped obese women who were emotional eaters lose weight over the course of three months, along with helping them reduce depression and anxiety. (7) Engaging in other activities that can help you relax are a better option than emotional eating.
“Do what you can instead of quitting when you can't be ‘perfect,’” Fear says. As if there’s such a thing as “perfect.” After all, research suggests that perfectionism surrounding food and weight, especially coupled with body dissatisfaction, contribute to disordered eating and even obesity in women. Researchers note that perfectionism can contribute to poor self-esteem, dietary restraint, and binge eating.
If a woman ate 1500 calories a day, along with some exercise, she would be able to lose about 1 pound a week. For a male, eat 2000 calories a day with some exercise, and you should also lose about 1 pound of weight a week. If you actually meant to say 100 calories per day, I would say you're crazy. A 10 month BABY needs around 820 calories each day. Now I can safely assume that you are NOT a 10 month old baby, therefore if you are eating 100 calories per day, then you are depriving your body in an extremely dangerous way.
The key to losing weight is eating fewer calories than you expend. That creates an energy deficit, so your body taps into other sources of fuel — namely, your fat stores — to make up the difference. You’ll be able to lose weight safely by creating an energy deficit of up to 1,000 calories a day, which will allow you to lose up to two pounds per week.
Instead of subjecting yourself to another endless workout, crank up the intensity and you’ll see results faster than you ever thought possible. The results of a study conducted at McMaster University in Ontario reveal that adult male study subjects who exercised intensely for a single minute had equivalent respiratory and metabolic changes to those who worked out at a slower pace for close to an hour, so if you want to burn through that belly fat, say so long to slow and steady.
When you're trying to lose weight, diet is one piece of the puzzle; the other is exercise. The AND recommends women over 50 engage in 30 minutes of moderate-intensity exercise -- such as a brisk walk or bike ride -- most days of the week to help burn extra calories. Two sessions per week of weight-training can help build and preserve muscle, which is beneficial for weight loss maintenance. According to the National Weight Control Registry, 94 percent of the people who have lost weight and kept it off engage in some sort of regular physical activity. If your doctor gives the okay for exercising, consult a personal trainer for fitness ideas that are right for you.

At any given time, there are dozens of weight-loss hypes in the marketplace that claim to take off 10 pounds in 10 days, or whatever. Desperation can tempt us to try anything — from "clean eating" to cutting out food groups entirely. Keep in mind: Just because an avocado-walnut-"crunchy"-kale-salad dripping in coconut oil is deemed "clean" by a so-called "expert" on your Instagram feed does not make it an unlimited food. Moral of the story? Avoid fads, eat real food, watch some Netflix, and unwind (perhaps with a glass of wine in hand). Now that's my kind of detox.
Trying to lose weight? Having trouble? Women often find it harder than men to shed excess pounds. In part that's because women's bodies have a tendency to "hold on" to a certain amount of fat. But in some cases the problem can be traced directly to certain habits and lifestyle traps - including many that can easily be remedied. Here are 10 weight-loss traps to watch out for:
“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.
People were not asked to count calories at all. Over the course of a year, both groups attended 22 classes reinforcing these very sound principles — and all participants had access to health educators who guided them in behavioral modification strategies, such as emotional awareness, setting goals, developing self-efficacy (also known as willpower), and utilizing social support networks, all to avoid falling back into unhealthy eating patterns.
Your weight-loss goals, personality and lifestyle al impact on your potential to lose weight, so selecting a plan that fits in with all these criteria gives you the best chance of success. Avoiding fad diets and fast-track options is important as these are rarely sustainable. When choosing a weight-loss plan, it’s important to consider the following points:
You know that recording what you consume is a good way to keep your weight in check, but Brittany Hicks, who dropped 110 pounds in college, didn't only write down what she ate—she also wrote down why she was eating it. "I realized I'd been using food to cope with stress," she says. "Just noticing that helped me do it less." Make sure you're not making these food journal mistakes so you can reap the rewards of eating and jotting, too.

Many diets, including Atkins and the keto diet, fit into this umbrella. A typical low-carb diet limits carbs to less than 60 g daily, but this can vary, according to the Mayo Clinic. (15) In a September 2015 review published in PLoS One, people following low-carb diets saw modest weight loss — although study authors note that long-term effects of the diet require further research. (16)


The Academy of Nutrition and Dietetics (AKA the top nutrition authority in America) released a revised paper this year saying that both vegetarian and vegan diets are best for people's health as well as the environment. If you're not ready to make a complete shift to meatless and cheese-less, consider "part-time" vegan and vegetarian plans, where you eat mostly plant-based at breakfast and lunch or on weekdays, and then eat fish, meat, dairy, and eggs only during designated times.
If you don’t have an established exercise routine, simply walking is the best first step toward weight loss. “Walking is a pretty good entry point for people,” says Gagliardi. This is particularly true if you have been out of the gym for a while and want to ease back into a workout routine. One small study published in The Journal of Exercise Nutrition & Biochemistry found that obese women who did a walking program for 50 to 70 minutes three days per week for 12 weeks significantly slashed their visceral fat compared to a sedentary control group.
You don’t have to go low-carb to ditch those extra pounds around your waist in a short period of time. In fact, opting for more whole grains might just get you there faster. Researchers at Tufts University have linked eating three or more daily servings of whole grains to as much as a 10 percent reduction in visceral body fat, the kind that ups your risk for chronic diseases, like diabetes, heart disease, and high blood pressure.

As a result, about four in 10 Americans are obese -- that’s a whopping 93.3 million adults -- which increases their risk of heart disease, stroke, type 2 diabetes, certain cancers and early mortality, and cost the country $147 billion in medical costs in 2008, according to the CDC. Nearly 80% of American adults are also not getting enough aerobic and muscle-strengthening activity, which is linked to about $117 billion in annual health care costs and 10% of premature mortality, according to the U.S. Department of Health and Human Services.


Diet.com is lauded far and wide for their individualistic approach to dieting. As most legitimate weight-loss plans for women will testify, a cookie-cutter diet is rarely successful as every body type, lifestyle, and individual is different. Diet.com embraces those differences and tailors its healthy weight-loss plans to fit your specific needs. Here’s how it works:

Try this interval-training trick on the elliptical trainer: Ride for 30 seconds as fast as you can, then immediately reverse your direction and ride for 30 additional seconds just as fast in the opposite direction. Rest 60 seconds, and repeat. The force of stopping your momentum, as well as going from a dead stop to full speed twice in the same interval, will give your fat-burning efforts a massive boost, says Alwyn Cosgrove, C.S.C.S.
In what is perhaps the biggest buzzkill of all time, sex doesn’t quite count as cardio or burn a significant amount of calories: Women burn about 3.6 per minute. "It’s still a good idea," Dr. Seltzer says, citing the activity’s other benefits, like increasing the output of the neurotransmitters serotonin and dopamine, which naturally reduce food cravings.
At any given time, there are dozens of weight-loss hypes in the marketplace that claim to take off 10 pounds in 10 days, or whatever. Desperation can tempt us to try anything — from "clean eating" to cutting out food groups entirely.

Moral of the story? Avoid fads, eat real food, watch some Netflix, and unwind (perhaps with a glass of wine in hand). Now that's my kind of detox.
The Mayo Clinic Diet is the official diet developed by Mayo Clinic, based on research and clinical experience. It focuses on eating healthy foods that taste great and increasing physical activity. It emphasizes that the best way to keep weight off for good is to change your lifestyle and adopt new health habits. This diet can be tailored to your own individual needs and health history — it isn't a one-size-fits-all approach.
“[These tools’] potential benefit is awareness,” Fear says. “Knowledge can be power, but these things can be counterproductive when they simply create alarm without any clear course of action to take. Seeing your weight rise doesn't necessarily provide you with any action steps you can take. It's just upsetting, like a fire alarm going off with no exit routes identified.” Langer notes that “in people who have a history of or are at risk for an eating disorder or compulsiveness, tracking anything should be off limits.”
The final possible culprit behind stubborn weight issues may be the stress hormone, cortisol. Too much cortisol will increase hunger levels, bringing along subsequent weight gain. The most common cause of elevated cortisol is chronic stress and lack of sleep (see tip #10), or cortisone medication (tip #9). It’s a good idea to try your best to do something about this.
