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
Successfully flattening your stomach is a matter of burning body fat and building muscle. The best way to burn body fat is through cardio exercises such as running, walking, elliptical training, and bicycling. With these exercises, burning stomach fat, shedding love handles, and building a six pack is completely do-able. So send your body the memo: flat abs are in style and it’s time to get yours!
Fibrous foods are as close to a “miracle belly flattening pill” as we have. Fruits, vegetables, and whole grains, particularly those high in soluble fiber, have been proven to reduce fat around your midsection. In addition, these foods fill you up so you eat less, flattening your stomach over time. Try one of these 5 easy ways to turn off your fat genes and keep the weight off for good.
The best low-cal diet plan isn't a diet so much as it is a method. CICO stands for "calories in, calories out" and is based on the mathematically sensible principle that as long as you're burning more calories than you're eating, you'll lose weight. All you need to get started is a way to track your calories—there are plenty of apps on the market although a pen and paper works great too—and a food scale to keep you honest about your portion sizes. (Also read this guide on how to safely cut calories to lose weight.) People love the simplicity and straightforwardness of the plan. And while it may not be the fastest way to lose weight, you're guaranteed to have success long term. (Just know that some weight-loss experts actually don't recommend calorie counting.)
It’s impossible to target belly fat specifically when you diet. But losing weight overall will help shrink your waistline; more importantly, it will help reduce the dangerous layer of visceral fat, a type of fat within the abdominal cavity that you can’t see but that heightens health risks, says Kerry Stewart, Ed.D., director of Clinical and Research Physiology at Johns Hopkins.
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.)

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.


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).
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)
The Mayo Clinic Diet is generally safe for most adults. It does encourage unlimited amounts of vegetables and fruits. For most people, eating lots of fruits and vegetables is a good thing — these foods provide your body with important nutrients and fiber. However, if you aren't used to having fiber in your diet, you may experience minor, temporary changes in digestion, such as intestinal gas, as your body adjusts to this new way of eating.
There’s also the impact fiber has on your gut health. By now you’ve likely heard of the microbiome—the trillions of bacteria that live in your digestive tract. It turns out that a predominance of certain strains of bacteria may encourage inflammation and weight gain, and eating fiber-rich foods can favorably shift this balance. While it’s too soon to say that changing your microbial makeup will prompt weight loss, it’s likely to send a “hey, stop gaining weight,” message.

Schedule a workout with a friend—you'll be less likely to skip out on it knowing that she is expecting you to show up. Or, use your workouts as "dates" where you can catch up with friends. "Every Wednesday, I take a Zumba class with the friends I met at Weight Watchers," says Michele August, who lost 117 pounds. "It's our weekly girls' night. We catch up, bond, and even enjoy a fun workout that burns a bunch of calories!" 
In reality, losing belly fat takes time. Although you probably won't completely transform your physique in two months, you can see progress in just a matter of eight weeks. Eric Bowling, an NASM-certified personal trainer at Ultimate Performance who helps clients with weight loss, told POPSUGAR you can achieve "drastic and tangible improvements" in eight weeks.
“Under normal conditions, humans absorb only about 80% of the nutrients from the food they eat,” says A. Roberto Frisancho, Ph.D., a weight-loss researcher at the University of Michigan. But, he says, when the body is deprived of nourishment, it becomes a super-efficient machine, pulling what nutrients it can from whatever food is consumed. Start eating again normally and your body may not catch up; instead it will continue to store food as fat.
The plan is simple: Commit to two weeks of restricted dieting, then transfer to a sustainable regime. Phase one: Cut out restaurant food, added sugar, eating while watching TV, snacking on anything other than fruits and veggies, and limit meat and dairy. You’re also asked to add four healthy habits, simple tweaks like having a good breakfast every morning.
Rounding out the top three for best weight loss programs on the U.S. News and World Report 2016 rankings, the Biggest Loser meal plan uses a pyramid system with fruits and veggies setting the foundation. Simple tenets back the plan: for example, being mindful of portion control, keeping a food diary, and exercising regularly. So, yes, work will be involved, but the plan is sustainable in the long-term and a likely way to shed pounds.

Weight Watchers is a household name for the majority of Americans. Why? Because it works. In fact, the U.S News and World Report named this the best weight-loss diet for 2016 in their annual rankings — and with good reason. The balanced program lets you eat what you want, track your choices via a points system, and build a weight loss support network with fellow Weight Watchers' members.

"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."


The fad military diet consists of low-calorie, odd food pairings such as bun-less hot dogs with banana, carrots, and broccoli. “Any diet like the military diet that severely limits the amount of calories you consume or eliminates one or more entire food groups puts any individual at risk for nutrient deficiencies,” says Kyle. “This can be more harmful than holding onto those 10 extra lb you’re trying to lose.” (32)

Having support is very important with weight loss. If everyone can get on board, it will be easier to achieve your goals. Talk to your family (or friends, roommates, etc) before starting your diet and let them know your plan. Explain why you are making this decision and ways they can help you succeed. Even if they do not change with you, that's okay! Go forward with your plan! They may decide to join you once they see you succeed with weight loss.
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.
The MIND—a mix of DASH and the Mediterranean diet—is supposed to help protect the brain and prevent Alzheimer’s disease, though much more research is needed to determine whether it really helps curb brain decline. People are encouraged to eat from 10 brain-healthy food groups: green leafy vegetables, all other vegetables, nuts, berries, beans, whole grains, fish, poultry, olive oil and wine. They are also told to avoid foods from five food groups: red meats, butter and stick margarine, cheese, sweets and fried or fast food.

You know the kind, says Jillian: "Everyone's like: 'Give up carbs!' 'Give up fat!' 'Wait, no, now I'm taking pills!' None of them are manageable long-term—and they wreak havoc with your metabolism! Because you're either starving yourself or you're cutting out a major food group. Then you go back into weight-gain mode, but it's even worse, because your body has adjusted to all that crazy fad crap."

Fighting belly fat is 80% healthy diet. Reduce calories by filling yourself up with protein, vegetables, whole grains, and replacing bad habit snacks with good ones. For example, if you have a sugar craving, replace your calorie laden latte with a Muscle Milk lite, one of my favorites, because it has zero sugar and a ton of protein that will satiate while also torching my sugar craving! Another great trick is a sprinkle of cinnamon in your morning coffee or oatmeal- the spice has been shown to help stabilize blood sugar. It also slows the rate at which food exits the stomach, which helps you feel fuller longer.
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."
Very low levels of thyroid hormone usually indicate an autoimmune reaction to the thyroid gland itself. This means you’ll have to take thyroid hormone supplements orally, usually the stable form T4 (Levaxin), which your doctor can prescribe for you. Your body will transform this into the active T3 hormone when necessary. The supplement dose should be adjusted so that you reach normal hormone levels (TSH, T3, T4) and sufficiently alleviate symptoms – though a few people feel best when keeping TSH slightly below normal.
“I lost 85 pounds between the ages of 39 1/2 and 41, and have kept it off for more than a decade. Part of how I did it was by saying ‘no’ to what I call No-Longer-Nourishing Commitments. I was working too many hours, which left me with little time or energy for working out or making healthy food. By saying no to some projects, I was able to devote more attention to preparing better food and moving my body. It also gave me more nourishing time with friends and family, which made junk food become less of a go-to comfort.” —Deb Thompson, 53, certified Integral Master Coach

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.
“Diet and exercise are a marriage that should never divorce,” said Giancoli, noting that the benefits of exercise aren’t restricted to the sheer number of calories you burn during thirty minutes on a treadmill. (Need one of those, by the way? We have some favorites.) Instead, research shows that muscle tissue burns more calories than fat tissue, proving that “muscle mass is a key factor in weight loss.”
But the whole idea of fast weight loss may be the root of the problem. According to a Time expose on the subject: “When people are asked to envision their perfect size, many cite a dream weight loss up to three times as great as what a doctor might recommend.” An improbable and disheartening goal, and one that obscures the truth that losing small amounts of weight — even ten pounds — still has great health benefits.

Caloric intake: Some people need more calories because of metabolic issues or high activity levels, and low-calorie plans might be insufficient. While it is true that less calories usually means more weight loss, and it’s normal to feel hungry some of the time while dieting, some diet plans are too strict and leave you feeling uncomfortably hungry most of the time. Consider if a diet plan will keep you satisfied.
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.
A 2012 study also showed that people on a low-carb diet burned 300 more calories a day – while resting! According to one of the Harvard professors behind the study this advantage “would equal the number of calories typically burned in an hour of moderate-intensity physical activity”. Imagine that: an entire bonus hour of exercise every day, without actually exercising. A later, even larger and more carefully conducted study confirmed the effect, with different groups of people on low-carb diets burning an average of between 200 and almost 500 extra calories per day.
