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.

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.

When you make purchases with a credit card, you only realize how much money you're spending in a conceptual sense—you don't actually see the cash coming out of your wallet. According to a study in the Journal of Consumer Research, that may lead you to buy more unhealthy, calorie-dense foods despite the extra cost (both money-wise and diet-wise). Researchers believe credit cards make it easier to make impulse buys.
Capsaicin, the compound in chili peppers that makes them hot, may speed up your metabolism, according to a study in Physiology & Behavior. Researchers say capsaicin activates your sympathetic nervous system, and that the effect on metabolism can last for more than 4 hours after eating. For recipe ideas, check out this beginner's guide to herbs and spices.
HCG, or Human Chorionic Gonadotropin, is a hormone produced during pregnancy by the placenta after implantation, and doctors sometimes prescribe it for fertility issues. But this hormone has also gained popularity as a weight-loss supplement — and using it as such can be dangerous. In fact, the U.S. Food and Drug Administration (FDA) warns against purchasing over-the-counter hCG, as these supplement products are illegal. (34)

“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.


Try to include an exact portion size of each food and beverage. Serving size matters! And remember, keeping an accurate food journal means writing down everything that you consume, including samples and tastes while you are cooking. We often eat without being truly conscious of it. Your new food diary is the best way to get a true idea of your food intake.
"These diets are so restrictive that of course you're going to lose weight fast because you're not eating enough calories to sustain basic activities of your body, let alone any exercise. That's nothing that any person can sustain for the long term," Hogan said. "The weight's going to come back if you do lose any weight, and then it's going to be harder to lose weight in the future."

We know that shedding unwanted pounds used to mean giving up your favorite foods, logging hours at the gym, and being hungry (and hangry) all the time. Fortunately, dropping a dress size (or two) doesn’t have to be that complicated or torturous. Sure, losing any significant amount of weight requires lifestyle changes and some hard work, but it all boils down to simple choices.
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.

Weight Watchers, which not only champions a sustainable diet but has sustained itself for over fifty years, is a favorite amongst nutritionists. Its practical, flexible philosophy of saving and splurging SmartPoints boils down to balancing out food choices. You can get tips, tools, and motivation by attending the traditional weekly meetings, or get the same resources through its user-friendly app. Either way, research proves that Weight Watchers’ social element supports weight loss. At about $4 a week, OnlinePlus costs about half as much as Meetings+OnlinePlus, which runs around $8 (your fees vary depending on the length of your commitment).


Do you know what to eat to lose weight? You might be relieved to know that you don't have to spend a lot of money or go to fancy boutique grocery stores to fill your fridge when you're trying to slim down. In fact, most products on the best weight loss foods list are common items that you can find in any supermarket.  Smart dieters eat these cheap and easy foods and slim down faster.
A. There hasn't been much research on this, but several studies suggest that weighing yourself more often, rather than less, may help with weight control. Findings published in the Annals of Behavioral Medicine on two large groups of people -- one group participating in a weight-gain-prevention study and the other participating in a weight-loss study -- revealed that those who weighed themselves more often were more likely to lose weight or less likely to regain weight over the next two years. The authors of the study say daily weighing is valuable to people trying to lose weight or prevent weight gain.
The customized support and abundant resources come at a price. This varies based on the intensity of your weight loss goals; we paid $60 per month. (We made an account before purchasing and received a 50% off offer by email to incentivize our membership. Tease them in the same way and see if you get the same deal.) If you want to get a look at all these perks before you purchase, you can try Noom free for 14 days.
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.

Noom helps you find and hold onto your Why while learning about other, smaller concepts that contribute to success. Self-awareness is big with Noom. The app offers short daily lessons that help you see and confront your own typical actions through introducing things like behavioral chains and triggers. If you can get past all the incessantly cheeky language (#noomerslovehashtags), it’s truly impressive how Noom deploys behavioral psychology to influence how you approach wellness.


If you dislike cooking, abhor making food choices, or simply want low-calorie options shipped to your door, Nutrisystem might slot into your life. But it can get expensive, and food selection and flavor are hit-or-miss. Mostly miss. “It’s enough substance to call it a meal, but the texture of every ingredient was lacking,” our tester reported without enthusiasm.
Weight Watchers, The Mayo Clinic Diet, and especially Noom provide a lot of behavior-based support to integrate these good habits. These include learning portions, logging food, and both giving and receiving external support. Nutrisystem doesn’t ask for any behavior changes save for subsisting almost entirely off their pre-packaged, pre-portioned meals.
In other words? "Drinking makes you more likely to eat sh*t," Dr. Seltzer says, referring to drunk foods. At the same time, he stops short of asking patients to quit alcohol cold-turkey to lose weight. Plus, research suggests you don’t have to, as long as your intake is moderate—i.e., less than about a drink a day. "If you drink a glass of wine every night and notice you eat more afterward, eat less early to account for this," he says. "Or, if you’re drinking four glasses of wine a week, drink three instead so you’ll won’t feel such a big difference."
Fancy coffee drinks from trendy coffee joints often pack several hundred calories, thanks to whole milk, whipped cream, sugar, and sugary syrups. A cup of regular coffee with skim milk has just a small fraction of those calories. And when brewed with good beans, it tastes just as great. You can also try nonfat powdered milk in coffee. You’ll get the nutritional benefits of skim milk, which is high in calcium and low in calories. And, because the water has been removed, powdered milk doesn’t dilute the coffee the way skim milk does. Here are 11 metabolism myths you have to stop believing.
You can see the pumpkin pie your coworker baked sitting on the giveaway table across the office. But according to research from St. Bonaventure University in Upstate New York, you won't get up and cut yourself a slice if you have a healthy snack right in front of you. Their study, published in the journal Appetite, revealed that even when people want to snack on something sinful, they'll go for whichever nosh is closest to them.

So how does this work? A quick run-through: The first tip was to eat low carb. This is because a low-carb diet lowers your levels of the fat-storing hormone insulin, allowing your fat deposits to shrink and release their stored energy. This tends to cause you to want to consume fewer calories than you expend – without hunger – and lose weight. Several of the tips mentioned above are about fine-tuning your diet to better this effect.
Skip the cream and sugar in your cup of joe, and opt for it black to help you lose weight fast. Black coffee has zero calories, and it can help you burn calories faster. According to a study published in the journal Physiology & Behavior, the average metabolic rate of people who drank caffeinated coffee was 16 percent higher than that of those who drank decaf.

Wrap up your morning meal with dessert—yes, really. In a Tel Aviv University Medical Center study, one group had a 304-calorie breakfast with 10 grams of carbs, while the other group ate a 600-calorie breakfast with 60 grams of carbs, which included a small sweet, such as chocolate, a doughnut, a cookie, or cake. Halfway through the 8-month study, both groups had lost an average of 33 pounds per person. At the end, however, the low-carb group regained 22 pounds, while the dessert group dropped an additional 15. Researchers say the dessert-eaters reported dealing with fewer cravings, and had a better chance of sticking to their calorie requirements for the rest of the day.
Obviously, it’s still possible to lose weight on any diet – just eat fewer calories than you burn, right? The problem with this simplistic advice is that it ignores the elephant in the room: Hunger. Most people don’t like to “just eat less”, i.e. being hungry forever. That’s dieting for masochists. Sooner or later, a normal person will give up and eat, hence the prevalence of “yo-yo dieting”.
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.
It can be difficult to lose weight and maintain a healthy lifestyle if you don't have adequate social support. Some weight loss programs offer in-person support group meetings, others offer one-on-one counseling via telephone or text messaging and still others use online message boards or forums to connect you with others using the plan.  Corresponding with like-minded people can make your fat-loss journey easier and more productive, but what level of accountability and interaction do you want or need? 
When you make purchases with a credit card, you only realize how much money you're spending in a conceptual sense—you don't actually see the cash coming out of your wallet. According to a study in the Journal of Consumer Research, that may lead you to buy more unhealthy, calorie-dense foods despite the extra cost (both money-wise and diet-wise). Researchers believe credit cards make it easier to make impulse buys.
Making meals from scratch is time-consuming, sure, but relying on frozen dinners and other packaged products won't help you out in the long run. One recent study found that we burn 50% more calories metabolizing whole foods than processed foods. So not only are you likely to decrease your calorie intake when prepping your own meals, your body will thank you with a metabolism boost.
If you like eating meat and want to lose weight, you might be tempted to try this recent extreme diet fad that proponents have made some pretty outrageous claims about. One: that eating nothing but meat can cure you of autoimmune diseases. The problem is that there’s no good research to support that notion, or any other health claim, for that matter. Indeed, omitting foods known to be good for you — fruits and veggies among them — can lead to a bunch of unwanted side effects, including constipation and potentially dangerous nutrient deficiencies. Still, since you’re cutting out so many food groups, there’s a decent chance you’ll lose weight, experts say. Regardless of any possible benefits you might see, this restrictive approach is definitely one you’ll want to ask your doc about before you even consider diving in.

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.
