Too little sleep or too much sleep can throw your stress and regulatory hormones out of whack, and may lead to weight gain. A single night of sleep deprivation can increase levels of ghrelin (a hormone that promotes hunger), making you more likely to overeat the next day. Reduced sleep may also lead to fatigue during the day (duh) and less physical activity, which may be another reason why people who regularly don't get enough sleep tend to gain weight.
Say cheese! Adding some extra calcium to your diet could be the key to getting that flat stomach you’ve been dreaming about. Over just 12 months, researchers at the University of Tennessee, Knoxville found that obese female study subjects who upped their calcium intake shed 11 pounds of body fat without other major dietary modifications. To keep your calcium choices healthy, try mixing it up between dairy sources, calcium-rich leafy greens, fatty fish, nuts, and seeds.
Did bikini season sneak up on you? Is your soon-to-be worn wedding dress still just a touch too tight? Did a last-minute invite for a beach getaway come your way? You're a lucky dog – and a panicked one too because you want to drop pounds, and fast. These 10 diets are likely to help you lose significant weight within a year, according to a panel of experts who reviewed 41 plans for the U.S. News Best Diets rankings. Just remember: Short-term weight loss is markedly different from long-term weight loss, which is more important for your health.
You may think you're vigilant about watching what you eat, but research shows that stolen bites and tastes can rack up a few hundred uncounted calories, which can put on pounds fast. Eating while distracted can cause mindless eating, too. When women who normally watched their portions had lunch in different situations, they ate 15% more (72 additional calories) while listening to a detective story, compared with when they ate alone and free of any distractions, found a study in the American Journal of Clinical Nutrition.
"When we’re lacking in sleep, our body’s hormones get thrown off balance which can impact our hunger levels the next day. We all have two hormones that affect our appetite: ghrelin and leptin. When we don’t get enough sleep, our ghrelin levels (the hormone that makes us feel hungry) rise, and our leptin levels (the hormone that makes us feel full) drop. This means that when we’re awake, we tend to eat more but feel less satisfied. Try going to bed a little earlier than usual to avoid this imbalance and remember to remove any distractions that might prevent you from nodding off."

Your body needs a certain amount of essential vitamins and minerals to function properly. What happens when you don’t get enough of them? What happens when you eat too little food, or when the food you eat isn’t sufficiently nutritious? Perhaps our bodies catch on and reply by increasing hunger levels. After all – if we eat more, we increase the chances of consuming enough of whatever nutrient we are lacking.
"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.

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.


You can get a lot of valuable vitamins and nutrients from fruit. However, when you just drink the fruit juice, you lose out on the fiber from the actual fruit that fills you up. As Rachel Harvest, a registered dietitian affiliated with Tournesol Wellness in New York, told Cosmopolitan, “Even 100 percent juice is just empty calories and another blood sugar spike.” If you’re serious about losing weight, here are 10 weight-loss products that are worth your money.
There’s a reason why protein takes center stage in many popular diet plans: it helps you feel full and stokes your metabolism enough to help you avoid the typical one or two pounds most adults gain each year. Your body burns slightly more calories after eating protein compared with fats or carbs, and protein from food also helps keep your muscles from deteriorating as you age. (Strength-building exercise is another important part of this process.) In order to get these benefits, you need to include protein at each meal, and getting adequate amounts of protein at breakfast — about 20 grams — is especially important. Making a beeline for the bagels or cereal means your body misses a key opportunity to rebuild muscle tissue, which naturally breaks down as you sleep. If this is your morning routine, your muscle mass will start to decline, and that means your metabolism will slow down. So skip the AM pastries and other carb-rich fare, and opt for an omelet or smoothie made with Greek yogurt or protein powder, instead.

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.”


The calorie restriction diet myth suggests you will win the fight against flab. While losing weight does come down to how many calories you consume, it’s the types of foods you eat that will determine how you feel as you lose weight and the kind of weight you will lose. If you have a poorquality diet — counting calories but eating junk food — chances are you’ll lose muscle rather than fat, and thus, suffer from slow metabolism.
"What I don't like about any commercial diet is that the focus is not on your actual food choices," Hogan said. "It's about calories or points or numbers, and that really takes away from your ability to be in tune with your hunger cues and your fullness cues and what you're really craving. If we become more in tune with those things, we naturally consume how much the body needs. Paying too much attention to numbers takes away from that."
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.
Also, while your menstrual cycle may not affect weight gain or loss, losing or gaining weight can affect your menstrual cycle. Women who lose too much weight or lose weight too quickly may stop having a period, or have irregular periods. Women who have obesity may also have irregular periods. A regular period is a sign of good health. Reaching a healthy weight can help women who have irregular periods to have cycles that are more regular. Learn more in our Menstrual Cycle section.
It's not just what you eat that can make you pack on pounds—it's also how much. Before dropping 102 pounds, DeGennaro did not have a grip on proper serving sizes. "Sitting down to dinner with my husband and three kids, I'd scarf down mounds of pasta and endless rolls," she says. "Adjusting to smaller portions was tricky at first; I'd round out meals with extra veggies to keep from getting hungry."
Sometimes, to whip your body into shape, you have to get a little nutty. While nuts are high in fat, it’s that very fat that makes them such powerful weapons in the war against a ballooning belly. In fact, research from Reina Sofia University Hospital reveals that study participants who consumed a diet rich in monounsaturated fats, like those in nuts, over a 28-day period gained less belly fat than their saturated fat-consuming counterparts while improving their insulin sensitivity.
“Getting deep down to the root of why you want to lose weight is a very powerful and eye-opening experience,” she says. “I do this exercise with my clients. I give them a piece of paper and they start at the top with the initial reason they want to lose weight. Often, it starts with reasons like ‘I will look better.’ Under that, I ask them why that is important. Sometimes there are some very deep and powerful reasons that are incredibly motivating like ‘I want to lose weight to travel on an airplane with my husband on our second honeymoon’ or ‘to be able to really play with my kids.’”

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).


To drop serious lbs, you need the one-two punch of aerobic exercise plus strength training. Resistance helps build and preserve metabolism-boosting lean muscle while burning fat and is especially key when you hit a plateau. Amanda Green lost 15 pounds in two months doing hour-long cardio DVDs, but it wasn't until she started running outside and lifting weights three times a week that she was able to ditch the last 15 of her 30-pound goal.
Because men are larger than women on average and have more muscle to support, men can usually eat more calories while still losing weight, compared to women. Portion control may be especially important for women. In one study, women who ate smaller portions of food (and less food overall) had lower BMIs than women who limited or avoided a certain type of food.2 This approach seems to work better for women than men.3

Losing weight on autopilot is appealing. But in the age of meal-delivery services (Blue Apron happens to be Whole 30-approved) — is there really a market need for gimmicky Nutrisystem? Our taste buds tell us no. You could easily recreate its no-prep diet by stocking up on breakfast bars, Lean Cuisine lunches, and signing up with the likes of HelloFresh for fast, healthy dinners. (Rough calculations tell us this approach would be equal or less than the monthly price of Nutrisystem.)
“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.”
"I use low-fat Greek yogurt in place of mayo in recipes, and it tastes great," says Krystal Sanders, who went from 185 pounds to 110 by coming up with healthy versions of her favorite restaurant foods. "It can also be used as a sour cream substitute." The possibilities are endless when it comes to this tasty staple, but you can start with these dessert recipes.
But I've seen some women beat themselves up over a few extra pounds, even though this does little more than destroy their self-worth. Berating yourself will not help motivate you to control your weight and improve your health. So the next time those negative thoughts creep into your head, recognize them for what they are and replace them with positive ones.
Choose the turkey sandwich over pizza and you think you're set, but again, looks can be deceiving. A turkey sandwich that comes on focaccia with cheese and mayo can deliver 970 calories. Two slices of pepperoni pan pizza total 520 calories. Put your sandwich in a spinach wrap instead of regular bread? It's the same difference, says Tara Gidus, RD, a former spokesperson for the Academy of Nutrition and Dietetics. "My clients think they get more nutrients and save on calories with 'healthy bread,' but often that's not the case."

The study began with 609 relatively healthy overweight and obese people, and 481 completed the whole year. For the first month, everyone did what they usually did. Then, for the next eight weeks, the low-fat group reduced their total fat intake to 20 grams per day, and the low-carb group reduced their total carbohydrate intake to 20 grams per day. These are incredibly restricted amounts, considering that there are 26 grams of carbs in the yogurt drink I’m enjoying as I write this, and 21 grams of fat in my half of the dark chocolate bar my husband and I split for dessert last night.
“Most people who have been lean their whole lives have a much better understanding of proper portion size than people who are overweight,” says Deborah Riebe, Ph.D., a professor in the department of kinesiology at the University of Rhode Island. “If they go out to eat, they’re much more likely to ask for a doggie bag right away or to leave food on their plate rather than cleaning it up.”
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.
So, obviously, what is going to work for each person is different, and that’s OK. If your weight-loss practices help you identify areas for behavioral change and give you tools on how to make that happen, or just help keep your motivation up or feeling good, great. “But if you are not losing weight, then the tools you are using aren't working for you,” Fear says. “Many people keep doing the same monitoring even though it's actually not helping them. A sense of control and organization are not to be confused with efficacy.” Use this as an opportunity to try something else.

Proponents of the Paleo diet say it's a much healthier way to eat than the standard American diet, which is often heavy on added sugars and processed foods. Critics say it's too restrictive, banning dairy, wheat and legumes -- food groups that many nutritionists feel should be part of a healthy diet. However, as we noted earlier in this section, veganism and vegetarianism also ban entire food groups and do not come under the same cloud of criticism.
There are endless ways to do interval training. One simple example: First, warm up for 10 to 15 minutes. Then, pick up your effort so you’re working hard (a nine on a scale of one to 10—you should be breathing hard, but not gasping) for 30 to 60 seconds. Go easy for one minute. Repeat for a total of 5 times, and the cool down for two to three minutes.
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."
You can get a lot of valuable vitamins and nutrients from fruit. However, when you just drink the fruit juice, you lose out on the fiber from the actual fruit that fills you up.

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.
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.
“Exercise should not be used to purge calories,” Albers says. “Instead, to boost your mood to keep you motivated.” The thing is, exercise is great for you and can make you feel awesome. And feeling good about yourself seems to be actually useful in weight-loss efforts. Plus, some research has shown that changes in exercise behavior can lead to changes in eating behavior. “In part, it is neurochemical. Movement and exercise you enjoy boosts your serotonin and dopamine levels, which makes you feel good all the way around,” Albers says.

Some people feel better supplementing the already active T3 (sometimes prepared from pig thyroid glands), as it can give a stronger effect than the T4 hormone, but its effect is often harder to control. Swedish healthcare rarely prescribes or offers such T3 treatment, as it often lacks advantages and may pose a risk when doses are high for an extended period of time.
