Preferred tastes: Think about whether the foods on a given diet are things that you generally enjoy. If you hate eating your greens, you might not like a diet filled with salads; but if you have a sweet tooth, a diet that substitutes milkshakes for meals might be more up your alley. Ask yourself whether you will enjoy the foods on a given diet, or if it will feel like a “diet” food that you won’t be able to stick with long-term.
Protein is naturally filling and takes longer to digest than simple carbohydrates. When people drank a whey protein drink, they lost about 4 pounds more and about an inch more from their waists over 6 months and felt less hungry than people given a carbohydrate shake instead. Other research in mice, found that when mice were given extra whey protein they gained less weight and body fat and more lean muscle, even when calories were the same. Whey protein is found naturally in yogurt and other dairy.

Real talk: It could take weeks or months to see the metabolic effects of exercise on the scale, and even then, building muscle, which is denser than body fat, could lead to weight gain. "Do what you like because it’s good for you," Dr. Seltzer says, noting the way exercise is awesome for your heart, mental health, and more—and that not all measure of progress can be seen on the scale.


While the American College of Sports Medicine warns that women who eat less than 1,300 calories a day and men who eat less than 1,800 risk slowing down their metabolism over time. But a rev-up stage that only lasts two weeks is approved by doctors and isn’t as difficult as it seems. Our tester found the Mayo Clinic day pretty satisfying, and still had enough energy to hit the gym.
You can eat twice as much pasta salad loaded with veggies like broccoli, carrots, and tomatoes for the same calories as a pasta salad sporting just mayonnaise. Same goes for stir-fries, omelets, and other veggie-friendly dishes. If you eat a 1:1 ratio of grains to veggies, the high-fiber veggies will help satisfy your hunger before you overeat the grains. Bonus: Fiber is highly beneficial for preventing constipation, which can make you look bloated.
Sodas and juices are essentially liquid candy: They contain up to 18 teaspoons of sugar and upwards of 240 calories per 20-ounce serving, and provide zero nutritional value. Experts point to soda as one of the top contributors to the obesity epidemic. Diet drinkers aren't off the hook, either. A study in the journal Obesity found that diet soda drinkers were more likely to have a high percentage of fat in their bellies. Researchers believe diet drinkers may overestimate the calories "saved," and then overeat.
Dairy products contain varying amounts of lactose (milk sugar), which slows down weight loss. What’s more, part of the protein in milk generates a significant insulin response, which can have the same effect. Consequently, cutting back on dairy products may accelerate weight loss. This applies especially to dairy products typically lacking in fat, such as regular milk and various yogurts, but be careful with full-fat dairy such as cream and cheese all the same. And don’t forget whey protein powder, which is pure milk protein.

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.
"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."
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.
Sleeping for more than five hours a night might seem like a luxury for some, but it can have a serious impact on your overall health. Not getting the recommended 7-8 hours of shut-eye a night puts you at risk for fatigue the next day, which means you’re more likely to crave and snack on high-calorie comfort food. Try to go to bed sooner so you can get a little more sleep, which will help you eat less. And to blast fat even faster, don’t miss these essential 55 Ways to Boost Your Metabolism.
Though they work through a variety of mechanisms, one thing weight loss pills have in common is tilting the calories in / calories out equation in your favor. Reducing calories in can come from supplement ingredients that suppress your hunger or reduce the amount of calories you actually absorb. Increasing calories out, which is the mechanism by which most weight loss pills function, can happen by increasing your energy expenditure or your fat oxidation.
If you like the idea of an actually useful app, but aren’t interested in tons of interaction or paying a large membership fee, we suggest MyFitnessPal. There are lots of nearly identical apps on the market, but this one provides the easiest, quickest food tracking we experienced, plus advanced options like goal setting and nutrition analysis. For education and support, you’ll have to turn to outside sources.
As funny as it sounds, sleep deprivation may make you fat — and not just because you're susceptible to cases of the late-night munchies (although there's that too). There's tons of research that demonstrates getting less than the desired amount — about 7 hours — of sleep per night can slow down your metabolism. Plus, when you're awake for longer, you're naturally more likely to nosh. So don't skimp on your ZZZs, and you'll be rewarded with an extra edge when it comes to shedding pounds quickly.
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)

Refined white breads are simple carbohydrates that your body processes as sugar, and can really hinder your weight-loss efforts. Whole grain bread, on the other hand, is chock-full of slimming fiber and can help you feel fuller, longer. Just be sure to read your labels. “If the ingredients at the top of the ingredient list read sugar, sucrose, fructose, corn syrup, white or wheat flour, these foods contain mostly simple carbs and should be limited,” Rebecca Lewis, RD, told Eat This, Not That! in our article for 20 Secrets for Eating Bread Without Getting Fat. “A food is only considered a whole grain if the first ingredient on the packaging says, ‘whole grain’ or ‘whole wheat.’”
Switch to Lighter Alternatives. Whenever you can, use the low-fat versions of salad dressings, mayonnaise, dairy products, and other products. "You can trim calories effortlessly if you use low-fat and lighter products, and if the product is mixed in with other ingredients, no one will ever notice," says Magee. More smart substitutions: Use salsa or hummus as a dip; spread sandwiches with mustard instead of mayo; eat plain roasted sweet potatoes instead of loaded white potatoes; use skim milk instead of cream in your coffee; hold the cheese on sandwiches; and use a little vinaigrette on your salad instead of piling on the creamy dressing.
There’s a large spectrum of where people can fall on a vegetarian diet: For example, vegans consume no animal products, whereas ovo-lacto vegetarians eat both dairy and eggs. The eating style may help with weight loss, suggests a review published in August 2017 in Nutrients, but some vegans and vegetarians may become deficient in specific nutrients, such as calcium, iron, zinc, and vitamin B12, according to an article published in December 2017 in Nutrition, Metabolism and Cardiovascular Diseases.

Squeezing in some refreshing lemon will not only help you drink more water; it also has detox benefits which are sure to help you lose weight fast. Lemons are rich in polyphenols, which are compounds that contain antioxidants. A study in the Journal of Clinical Biochemistry found that mice who were fed lemon polyphenols were less likely to gain weight and accumulate body fat.

“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.

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.

25. Eat breakfast. A review published in the American Journal of Clinical Nutrition showed that those who eat breakfast are more successful with long-term weight maintenance. Other research has shown the same for weight loss. Grab hard boiled eggs, scrambled eggs, Greek yogurt, a piece of fruit and handful of nuts, or make a smoothie. It doesn't have to be fancy.

Being healthy is really about being at a weight that is right for you. The best way to find out if you are at a healthy weight or if you need to lose or gain weight is to talk to a doctor or dietitian, who can compare your weight with healthy norms to help you set realistic goals. If it turns out that you can benefit from weight loss, then you can follow a few of the simple suggestions listed below to get started.


Diet.com is lauded far and wide for their individualistic approach to dieting. As most legitimate weight loss plans for women will testify, a diet can’t be cookie-cutter since every body type, lifestyle, and human being is different. Diet.com appreciates these differences and tailors its healthy weight loss plans to fit your specific individuality. Here’s how it works:
The efficacy of Nutrisystem boils down to portion control. A tiny tray of frozen tuna casserole doesn’t provide a lot of nutrients or satisfaction, but if that’s all you have for dinner, you’re keeping calorie count low. We entered in a couple Nutrisystem meals and found their point count to be mid-high, between 7 and 9. Ultimately, tiny amounts of not-wholesome foods doesn’t teach you to eat well.

The researchers hypothesize that participants who abstained from animal products dropped significantly more pounds since plant-based foods include loads of filling fiber and slow-to-digest complex carbs. Though more research is needed to confirm these results, the study authors write, "Vegetarian diets appeared to have significant benefits on weight reduction compared to non-vegetarian diets."

A heavy-handed pour will negate any of the health benefits you get from sipping a glass of wine. One serving of wine racks up 125 calories, and many of today's fishbowl-sized glasses hold three servings. (For the math-challenged, that's 375 calories—the size of a small meal.) Here, Cynthia Sass, MPH, RD demonstrates how to pour the perfect serving of wine.


Packaged meals: Many diet plans rely on meal-replacement bars, shakes, or other snack type foods. Still others rely on frozen entrees as a major part of your diet. Ask yourself if you are okay with a bulk of your diet relying on prepackaged snacks, shakes, or frozen meals, or if you prefer the flexibility of cooking your own meals or eating out frequently.
Nearly 30% of U.S. adults say they're trying to go gluten free—but unless you've been diagnosed with celiac disease, there's really no need. In fact, cutting all gluten foods (such as wheat, barley, and rye) from your diet won't necessarily help you lose weight. Gluten-free junk foods are everywhere, and a gluten-free cookie or slice of pizza is just as bad for you as the regular kind.

“My dad is like a food-pushing wizard, he’s always pulling stuff out of his pockets or showing up with delicious food,” says Mary Mock. While the family tradition of surprise sweets was fun, when it came time to lose weight, she knew she had to put a stop to all that temptation. “At first, he seemed hurt when I kept saying no but when I explained it was for my health, he got on board. Sometimes I still have to remind him though!” she says.
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.
Reviewers say Nature’s Variety is a great choice for cats that need to maintain their weight. Since it’s slightly higher in fat (a result of the increased protein from raw food), it may be a little more difficult for your cat to lose weight on this food. But it’s a great choice for those who have a picky eater that tends to put on the pounds and needs a great weight maintenance food.

eDiets doesn’t believe in reinventing the wheel. Instead, this diet marketplace gives members access to some of the most effective diet plans to date. While eDiets does offer fitness tools and online tracking capabilities, what most members really enjoy about eDiets is their weight loss food plan selection. Particularly suited for people with specific dietary or health restrictions, eDiets helps you find a menu that both suits your lifestyle and caters to your particular needs. For example, if you are a diabetic, their Glycemic Diet will deliver you nutritious and tasty meal plans that will help you maintain health and lose weight at the same time. Other weight loss meal plans include a Mediterranean Diet, Heart Smart Diet, and Gluten-Free option.
Ranging from just-juice to just-tea cleanses, these typically short-term plans can be dangerous. “Detoxes and cleanses are usually low in calories, protein, and fiber, all nutrients that our bodies need to function,” says Alissa Rumsey, RD, who is in private practice in New York City. “These plans leave you feeling hungry and cranky, causing a rebound food binge once you stop the detox.”

It sounds silly, but switching which hand you eat with can save you calories, and help boost weight loss. “It takes 15 minutes for your brain to realize that you’re full,” celebrity personal trainer Jay Cardiello told us in our article 40 Weight Loss Tips for Over 40. “To give your mind time to catch up to your mouth, simply switch your fork to non-dominate hand. It may be frustrating, but it’s a simple and unnoticeable way to curb overeating and lose weight.”


Fresh, in-season produce gives you the biggest nutritional boost, but frozen veggies come in a close second. Very shortly after being picked, these fully ripe veggies are frozen, allowing them to lock in many of their nutrients. Having a stash of veggies in your icebox makes healthy eating on the fly oh-so-easy—and reduces the chance you'll order in a pizza.
Consider a diet's overall approach to food. What will you be eating every day? Is there much variety, or will you be eating the same foods frequently? If most (or even some) of the foods on a plan aren't enjoyable, within your budget, or readily available, you're going to find a particular plan hard to stick with. Ask yourself: realistically, could you eat the foods on this plan more or less for the rest of your life?

Skimping on sleep sets you up for a host of health problems, such as increased risk for depression, type 2 diabetes, and stress. Here's one other benefit to spending enough time in bed: You're more likely to be a healthy weight. University of Chicago research revealed that dieters who were well-rested lost more fat than those who were sleep deprived.
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.
