Sure, there's your one friend who swears by the Taco Cleanse. And that other friend who ate nothing but broccoli soup for a month and dropped 20 pounds, found the love of her life, and got promoted at work. But before you start blending 80 stalks of broccoli into a cup or crunching your way through a crate of tacos, check out which diets are backed by science. Because don't you want to try one that will do the trick for you?

These fatty acids rocketed to fame for their ability to decrease the harmful inflammation that is associated with many chronic diseases—including obesity. Crandall is quick to point out that researchers have yet to find a cause-and-effect link—so don’t expect to pop a fish oil supplement, for example, and drop 10 pounds. But, she says, getting omega-3s from whole foods such as nuts, seeds, and fatty fish like salmon is a good way to hedge your bets. And bonus: If you’re suffering from other kinds of inflammation, that can lessen your willingness to be active, omega-3s might help there, too. Find out the fat-burning foods you should add to your diet.
We have reviewed online diet services for the past 11 years. In our most recent testing, we compared nine services by evaluating each program's features and having volunteers try out the services. We have determined that Weight Watchers is the best program overall because it truly helps you make dietary and exercise changes to improve your lifestyle and keep extra weight off for the long run. It comes with helpful tracking apps and boasts a strong online community where you can learn and share ideas with other service users. 

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.
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."
Eating too little can be extremely dangerous for your body. According to Medical News Today, having a Body Mass Index (BMI) of under 18.5 can lead to malnutrition, osteoporosis, developmental problems, a weakened immune system, anemia, and chronic fatigue. Healthline reports that the average woman needs about 2000 calories per day to maintain her weight and about 1500 calories to lose one pound of weight per week, though you should consult with your healthcare provider to see what's best for you.
So it’s no wonder that losing weight and getting in shape are among the most popular resolutions year over year, because so many people can’t keep them; 80% of New Year’s resolutions fail by February. So Moneyish spoke with several leaders in the field of obesity research and prevention who have reviewed the science surrounding weight gain and loss to explain what to eat and avoid; how much exercise you need and which workouts work best; as well as their tips for making these moves a part of your new, well-balanced life in the New Year.
If you watch TV often, you've probably seen a commercial pop up for Jenny Craig. When you do the diet, you receive a unique weight loss plan for your specific lifestyle and have a personal consultant to check in with at least once a week. And, the meals are delicious: There are more than 100 menu items to choose from for your meals, which are five a day plus one snack of your own.

Intentional weight loss is the loss of total body mass as a result of efforts to improve fitness and health, or to change appearance through slimming. Weight loss in individuals who are overweight or obese can reduce health risks,[1] increase fitness,[2] and may delay the onset of diabetes.[1] It could reduce pain and increase movement in people with osteoarthritis of the knee.[2] Weight loss can lead to a reduction in hypertension (high blood pressure), however whether this reduces hypertension-related harm is unclear.[1][not in citation given]
Summertime is the season for all things outdoors.  For many of us, the warmer months mean donning sleeveless shirts, shorts, and bathing suits.  It’s also the time of year when people worry the most about their appearance, or more importantly, losing that stubborn fat that clings to your waistline and reminds you of all of the culinary indulgences you enjoyed over the winter.  While there are countless miracle pills and quick fixes available out there, most of them either don’t work or carry incredible health risks.
Because the diet isn’t as restrictive as a traditional vegan or vegetarian diet, it may be simpler to stick with — hence its No. 2 ranking in U.S. News & World Report’s Easiest Diets to Follow category. Because you’ll be eating meat some of the time, you may also be at a lower risk of the aforementioned nutrient deficiencies that vegetarians and vegans may face.
“Diets rich in trans fats not only promote belly fat but also mobilize fat stored in other areas of the body to the stomach,” explains McDaniel. “Sources of trans fats include vegetable shortenings, processed baked goods such as cookies and crackers and fried foods. Avoid foods that contain the ingredient “partially hydrogenated oil” in the ingredient list at all costs,” she cautions.
Be choosy about carbs. You can decide which ones you eat, and how much. Look for those that are low on the glycemic index (for instance, asparagus is lower on the glycemic index than a potato) or lower in carbs per serving than others. Whole grains are better choices than processed items, because processing removes key nutrients such as fiber, iron, and B vitamins. They may be added back, such as in “enriched” bread.
High-intensity interval training—HIIT—has gained a reputation as an efficient way to get fast results. This workout involves short (30 seconds to five minutes), vigorous bursts of activity interspersed with periods of rest for maximum results. Incorporating HIIT into your strength training may offer even more results, according to a recent study by the American Council on Exercise—the results suggest the combo may be even more effective in burning fat fast.
Additionally, many women have to face one lifestyle change before getting to another, such as overhauling eating habits before taking on exercise. For example, Michelle DeGennaro got a handle on her diet and soon after found that she was more inclined to exercise. "Feeling lighter on my feet was thrilling, and it gave me the confidence to start walking every day," she says. And as Blanca Valdez noticed, "Eating right made my energy soar, which I channeled into exercise." She has kept off 78 pounds.
Most people think of cardio as a weight loss all-star, but you don’t need to spend all day on the treadmill to slim down. In fact, you might want to concentrate your efforts in the weight room. Muscle is metabolically active tissue, which means that it burns calories even when you’re not lifting; your body burns calories just to maintain muscle, so the more of it you have, the more calories you torch. You lose muscle mass naturally as you age, a process known as sarcopenia, which is why losing weight tends to get tougher the older you get. One study found that just ten weeks of resistance training increased resting metabolic rate (the number of calories your body burns when you’re not doing anything) by 7 percent. Check out this simple strength training routine that challenges your entire body.
Replace your weekly cardio session with circuit resistance training to whittle your middle. “High-intensity circuit training with dynamic movements is one of my favorite ways to build muscle and burn fat all over the body, says Rich. “There is no possible way to spot-reduce fat, so it’s important to train the entire body to lose fat overall. Performing moves like burpees, jump squats, mountain climbers and fast push-ups are great examples. If you have 40 minutes to work out, do twenty minutes of cardio and twenty minutes of circuit resistance training. You’re sure to see the difference in your body.”
Do you even lift, bro? If you’re serious about getting rid of that belly fat fast, resistance training might just be the key. A study from the Harvard School of Public Health found that adding weight training to adult male test subjects’ workouts significantly reduced their risk of abdominal obesity over a multi-year study period, although doing the same amount of cardio had no such effect. Research from the University of Maryland even found that just 16 weeks of weight training boosted study participants’ metabolic rates by a whopping 7.7 percent, making it easier to ditch those extra inches around your middle.
According to Healthline.com, "Researchers have found different types of bacteria play a role in weight regulation, and having the right balance can help with weight loss, including loss of belly fat. Those shown to reduce belly fat include members of the Lactobacillus family. These include Lactobacillus fermentum, Lactobacillus amylovorus and especially Lactobacillus gasseri.” If a slimmer belly is your goal, make sure your probiotic contains one or more of these bacterial strains.

One note about this diet plan before we dive in. A personal trainer by profession, Jillian Michaels’ weight-loss plans are not for the fainthearted. She’ll take you on a journey, transform your body, and make you reach the fitness goals you’ve been craving…but it won’t come easy. Go into this plan with the determination and awareness that you’ll be working hard, and the results will really amaze you.
But you'll lose the most fat by doing HIIT, or high-intensity interval training. This training technique involves working at full throttle for short intervals -- typically 10 seconds to a minute -- then recovering at a slow pace or resting for a minute or two. It increases your metabolism after a workout, since your muscles need to work hard to get "back to normal." HIIT also burns more belly fat than traditional, steady-pace cardio, according to Penn State University.
This high-fat, adequate-protein, low-carb fad diet sends the body into a state of ketosis, in which the body uses stored fat for energy. Research published in Clinical Cardiology suggests the ketogenic, or “keto,” diet can be an effective weight loss method, but to be successful, you must follow the plan consistently with no cheat days — otherwise, you’re just eating a high-fat diet that may be high in unhealthy fats for no reason. (1) (A pro tip? If you're planning on doing the diet, consider perusing this complete keto food list and reading up on the healthiest fats for keto diet followers.)
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.
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."
Are you like Old Faithful when it comes to your morning walk or evening jog? Know this: The more you do an activity, the more your body adapts to it, so you burn fewer calories. If you want to light a fire under your metabolism, consider cross-training. For example, if you normally walk, try biking instead. "Since you're not used to working all those different muscles, it's a more intense workout, which can translate into a greater metabolic after-burn because your body is working harder to recover and get oxygen to all your tissues," says Carol Espel, M.S., an exercise physiologist for Equinox Fitness Clubs in New York City.

Motivation and encouragement: Every person has different needs when it comes to what motivates them to succeed. Think about how you have met other important goals, or quit bad habits in the past. Would you be more likely to succeed using social media, in-person meetings with strangers or acquaintances, or expert counseling using text messaging, phone calls or email?

A 2018 study among more than 600 adults who were tracked for a year concluded that while there are different paths to weight loss, the advice to limit added sugars and refined grains, add more veggies to your plate, and eat more whole foods — in other words, focusing on the quality of your diet — is the way to go. People who followed this advice lost weight without worrying about calories.
Sometimes, you might need an external motivator—like a race or a competition—to keep you on track. After a slow start to her slimdown, Maribel Contreras decided to sign up for a 12-week body transformation contest at her gym. She swapped out her fast-food trips for healthy homemade meals and revved up her workouts, which ultimately helped her win the competition. She now maintains a 77-pounds-lighter frame. 
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.
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
Feel free to adjust the plan to your preferences. For example, we have desserts in the Meal Plan (part of the 30-Day program), but since you’re in the habit of going without desserts and treats you may want to avoid the desserts. Some people feel too restricted without treats and end up binging if they don’t get to indulge semi-regularly, so those lower sugar treats a good option. For others, it’s better to avoid all sweet things, since they can trigger overeating and they may achieve faster results by staying away from all sugar.

Studies have also shown a link between high sugar intake and increased abdominal fat. But as Healthline.com points out, you should realize belly fat doesn't just come from refined sugars. Even natural or "healthier" sugars (such as honey) should be limited. Cutting back on your sugar intake is a simple way to lose belly fat without exercising or burning calories.
Water isn’t just a calorie-free beverage, it’s also essential to the process of metabolizing fat, known as hydrolysis, says Pence. So it’s important to drink enough fluids every day—and you’ll need even more if you’re overweight. A good rule of thumb is to drink a milliliter of water for every calorie you consume. Not into the metric system? If you’re following a 2000-calorie diet, that comes to 67 ounces or just over a half gallon of water.
I had my dad sit down and binge-watch MDIBTY, and he finally gets it. He thought my relative ease at dropping 75lbs while eating things like bacon cheeseburgers and salmon with hollandaise was due to my relatively young age. Seeing Kurt melt before his eyes made him think he can do it too. And he has a freezer full of venison to get him started. Can’t wait to have my healthy dad back. Hopefully, he’ll regain the health he needs to hunt with my brothers and I like we used to.
Over the last three months I’ve lost 22 pounds simply by upping my exercise and reducing bad calories. I’m 68 years old, always in good shape, but added sedentary pounds as I aged. (6 feet tall, 212 pounds before — 190 pounds now) I’ve generally restricted my diet to about 1200 calories a day — 200 – 300 for breakfast, 200 for lunch, and about 700 or less for the rest of the day. I try to vary the foods, do as much exercise as I can (biking, swimming, walking, weights). I drink as much non-caloric liquid as I can and I try to find food that fills me up — vegetables, fruits, mostly. I eat some cheese and a good hamburger occasionally, although I avoid most meat. I still work full time. I realize the discipline necessary, but it’s not that hard to do. I rely on a good scale and moderate my diet each day to keep a constant weight. My blood pressure has dropped from 130/80 to 117/72 and heart rate is resting 58. I’m lucky that my chronic diseases are not yet serious (osteoarthritis and borderline cholesterol, although I dont take statins because of reactions). I’m not a diet fadder, but using common sense goes a long way. Eat smart and work out. MM
How much fiber should I eat per day? Most Americans eat less fiber than the USDA daily recommendations suggest. This article looks at the guidelines for fiber intake in men, women, and children. We also talk about how fiber can help with weight loss, and discuss how much fiber is too much. Learn about good sources of dietary fiber and a handy meal plan. Read now
In a nutshell: the plan uses 6 days of ketosis – when your body burns fats for energy – followed by 1 day of carbohydrate loading along with constant toxin binding supplements to help your body get rid of the released toxins.  This protocol isn’t low-calorie, and you don’t run the same risk of causing metabolic problems that you do when you follow a low-calorie diet.

Set yourself up to lose excess belly fat by setting realistic goals. You won't be able to lose fat exclusively from your belly -- it will come from all over your body, including your midsection -- or shed 20 pounds in just a week. You can, however, lose 1 to 2 pounds of fat to start slimming your midsection, using sustainable methods that'll allow for larger weight loss over longer periods of time.
