The "all meat all the time" low-carb approach or strict veganism can be great options for people who thrive on clear diet rules (and those two are actually the most popular diets out there) but these extremes are not for everyone. If you prefer more of a moderate approach, the Flexitarian diet is the clear winner. The "flexible vegetarian" mindset allows you a healthy balance of plant-based foods, responsibly sourced meats, and quality fats. The best part? It's not super restrictive, so you have plenty of nutritious food options. (Start here: How to Adopt a Flexitarian Diet)

Foods are given a certain point value, which is determined by how many nutrients it provides. As long as you stay within your point limit, you should lose weight. Weight Watchers is known for having a large community that is active and vibrant. You can attend weekly meetings near you or online, and the Connect app gives you further opportunities to connect with other users. If you want additional assistance, you can pay more for personal coaching. Like with many other online dieting services, there is a start-up fee in addition to the monthly payments. Our testers found this service to be very motivating and satisfying. Part of this motivation comes from company-hosted weight loss challenges, exercise plans, portion control tools and a dining-out guide. Weight Watchers doesn't provide a calorie tracker since it works on a points system, which makes it different from most other diet services out there. It helps you track your eating and activity, and it allows you to view progress reports, but there are no exercise tips.
Weight training is the ultimate way to burn calories fast. "A pound of muscle burns up to nine times the calories of a pound of fat," explains Richard Cotton, M.A., chief exercise physiologist for myexerciseplan.com. Weight training increases your resting metabolic rate, which is the number of calories you burn while sitting on your butt. What's more, it gives your metabolism an added boost after you exercise, staying in overdrive for up to two hours after the last bench press, according to a study published in Medicine & Science in Sports & Exercise. Strapped for time? Try these quick moves: squats, bench step-ups, lunges, push-ups, pull-ups and planks. In a pinch, just do single sets of 10 for each exercise — you'll get optimal results for the time invested.
Gym memberships can be expensive, and some days you just can't make it into the gym. Or maybe, you might not feel comfortable in a gym quite yet. At the start of her weight loss journey, Suheily Rodriguez says he was too embarrassed to go to a gym. "So I built a home one," she says, "where I exercised an hour a day, six days a week." She credits this to her 96-pound weight loss.
After 30 days on the diet, you’ll slowly add in one of the restricted foods — one at a time and for a few days only — to see how your body reacts. At this point, you can continue just avoiding the ingredients you suspect you’re sensitive to, or go to an allergy specialist to receive confirmation and see if there’s anything else you might be allergic to.
When you go on a "program" to lose body fat, you may set yourself up for failure. A program implies an end point, which is when most people return to their previous habits. If you want to lose fat and keep it off, make changes that you can live with indefinitely. Don't over-restrict calories, and find an exercise program that adequately challenges you, provides progression, and offers sufficient variety so that you can maintain it for years to come.

To start off, aim to do ab work 3 or 4 times a week on non-consecutive days with at least 24 hours of rest in between sessions, says Gagliardi. During those sessions, you can start with simpler moves like crunches, bicycle crunches, and planks. Even though you may only be directly targeting your abs 3 or 4 times a week, you should still be activating your core (aka, tightening your ab muscles) in every workout you do, says Gagliardi.


Thus it's best to avoid thinking about a weight-loss diet in terms of a temporary diet designed to help you get to your goal weight. Doing this only sets you up for failure. You’ll either fail to adhere to the diet and never reach your goal weight, or you’ll regain the weight after you’ve reached your goal weight. This is biggest reason why most people regain the weight they lost. Albert Matheny, a dietitian cited in an article about the University of Toronto study, sums it up perfectly, "You didn't gain 20 pounds overnight. It took time. The same goes for losing 20 pounds. Consistency and change of lifestyle over the long term is what leads to health and weight-loss success.”
Don’t buy your tickets to Bonnaroo just yet; the kind of acid that will help you slim down is the stuff right inside your cabinet. A 12-week study published in Bioscience, Biotechnology, and Biochemistry reveals that obese study subjects who made vinegar part of their diet dropped more belly fat than a control group, and other research suggests that acidic foods, like vinegar, can increase the human carbohydrate metabolism by as much as 40 percent.
These may seem like exercises for guys, but not all squats are done with a barbell loaded with lots of weight. (Although women shouldn't fear heavier weights; they don’t make you bulky.) Variations of these exercises are timeless and extremely effective. Grab a pair of dumbbells and try Bulgarian split squats (Click here to see a how-to video.). Your legs and butt will thank you.
Some cheat meals are better than others. And a high-carbohydrate, moderate-protein meal, however “naughty,” can help you stay on track. The reason: Carbohydrates have the greatest influence on leptin levels, which help you burn fat and feel satisfied. And protein has the greatest influence on satiety because of its influence on appetite-regulating hormones and high thermic effect—the process of digesting protein requires more energy of your body than any other macronutrient. Need an example? How about a few rolls of sushi? Steak and a potato? Pancakes and an egg white omelet? Spaghetti and meatballs? The options are virtually unlimited.
The best way to lose weight on the Bulletproof Diet is with Bulletproof Intermittent Fasting.  But if waiting for results just isn’t your thing, you can use this Bulletproof Rapid Fat Loss Protocol – but only if you are currently significantly overweight or obese, and you have healthy, functioning kidneys and liver.  However, you need to understand that your body stores toxins in fat that your liver couldn’t excrete, so when you lose weight very rapidly, those toxins are released and can make you very sick.  This Bulletproof Rapid Fat Loss Protocol helps you avoid any side effects from this toxin release, so it’s important to follow the plan carefully.
There's a reason you've been hearing so much about cutting meat out of your diet lately. It's not just great for your body, but also a quick way to shed some extra pounds. "Consider swapping a few meat-centric meals each week for ones centered around vegetarian proteins — or give a full-fledged vegetarian diet a try if that's of interest to you," Gorin says. "Research shows eating a vegetarian diet may boost and speed up weight loss, resulting in a loss of up to 10 pounds." Gorin recommends topping a salad or filling a veggie taco with vegetarian protein sources like pulses — which are beans, chickpeas, lentils, and dried peas — to give your weight loss a boost. One study found eating ¾ cup of pulses daily led to a loss of close to a pound over about six weeks, versus people not eating pulses daily.
In 2008 between US$33 billion and $55 billion was spent annually in the US on weight-loss products and services, including medical procedures and pharmaceuticals, with weight-loss centers taking between 6 and 12 percent of total annual expenditure. Over $1.6 billion a year was spent on weight-loss supplements. About 70 percent of Americans' dieting attempts are of a self-help nature.[24][25]
This drug is an injected variant of a satiety hormone called GLP-1. It slows down how quickly the stomach empties and tells the brain that you don’t need to eat yet – a great idea for losing weight. As a bonus this drug works fine while one is on the keto diet and it works even better with intermittent fasting – for a rapid weight loss with no hunger.

Load up on low energy density foods, like vegetables, fruits and fat-free broths. A few minor tweaks can lower the energy density of your favorite meals, too. For example, substitute a half-cup of spaghetti and a half-cup of spiralized zucchini "zoodles" for a full cup of spaghetti. Or make a chicken, vegetable and brown rice soup instead of serving grilled chicken with brown rice and veggies; the broth is often very low or virtually free of calories, lowering the energy density of your meal, so you may fill up on fewer calories.
IBS, or irritable bowel syndrome, is the most common gastrointestinal disorder. IBS symptoms include nausea, diarrhea, constipation, stomach pain, and bloating—So. Much. Bloating. While the causes aren’t all known, it’s thought to be linked to lifestyle factors like diet, exercise, hormones, and stress. Sufferers often find that making changes in these areas eliminates or reduces their IBS (and their stomach circumference!). Here’s how these 10 myths about fat can keep you from losing weight.
MyFitnessPal: An app widely recommended by trainers and fitness enthusiasts, MyFitnessPal is great for tracking macros. Goal macros: 50% carbs, 30% fat, 20% protein. It further breaks these general guidelines into specific gram amounts that make it easy to see how some macros add up quick (carbs) and others don’t (protein — hitting 64 grams takes conscious effort!).
People often cut out dairy when dieting, but cow’s milk has a lot of the nutrients that are essential to fat burning, including vitamin D and calcium. It’s also a great source of protein, which you need to build lean muscle, which is why experts say milk is a better post-workout drink than other beverages. Some research suggests that chugging moo juice after exercise results in more muscle gain and fat loss than drinking energy drinks. Find out more calcium-rich foods that are natural fat-burners.
You don’t have to be the next Usain Bolt in the making to enjoy some serious belly-slimming results from hitting the track from time to time. Even a moderate-rate jog a few times a week can blast through that belly fat; in fact, a study conducted at Duke University Medical Center found that, over the course of an eight-month study, overweight adult study subjects who jogged 12 miles a week lost the most belly fat and burned 67 percent more calories than participants who did an equivalent amount of resistance exercise, or a combination of cardio and resistance work.
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.
You know that recording what you consume is a good way to keep your weight in check, but Brittany Hicks, who dropped 110 pounds in college, didn't only write down what she ate—she also wrote down why she was eating it. "I realized I'd been using food to cope with stress," she says. "Just noticing that helped me do it less." Make sure you're not making these food journal mistakes so you can reap the rewards of eating and jotting, too.
"Probably the most important lesson I've learned is that it's a constant struggle, but I've also learned that I am not alone in the battle," says Cara Lynn. "I've managed to find like-minded people who battle the same demons and who slay similar dragons. The fitness community is like no other I've ever been a part of, and I'm thrilled to have found it." (Here's more on how joining an online support group could help you meet your goals.)
The main advantage of the low-carb diet is that it causes you to want to eat less. Even without counting calories most overweight people eat far fewer calories on low carb. Sugar and starch may increase your hunger, while avoiding them may decrease your appetite to an adequate level. If your body wants to have an appropriate number of calories you don’t need to bother counting them. Thus: Calories count, but you don’t need to count them.

Then, there’s biochemistry. In women, ghrelin — the “I’m hungry” hormone — spikes after a workout, while leptin — which tells the brain ‘I’m full!’ — plummets, according to a 2009 study in the American Journal of Physiology — Regulatory, Integral and Comparable Physiology. Not so in men. So post-workout, women tend to eat more, which puts them at risk to gain weight. Men don’t experience this same hormonal fluctuation.
The Rapid Fat Loss Protocol combines a modified cyclical ketogenic diet with mTOR stimulation, mitochondrial optimization, and ongoing toxin binding. The result is rapid fat loss with fewer – or no (we think) –  metabolic problems associated with VLCD (very low-calorie diets). It will combine a 6-day ketogenic phase using Bulletproof Coffee, followed by a 1-day high carb re-feeding.
But in order to get to your goal as quickly as possible, you've got to forget about crash dieting. That's because making strategic tweaks to your diet and exercise plan, rather than skimping on calories and exercise bingeing, is the fastest way to torch fat and keep it off, says Torey Armul, R.D. spokesperson for the Academy of Nutrition and Dietetics.  
“One of the most under-appreciated magic fat-burning elixirs is water,” says Ajia Cherry, personal trainer and Founder at Functional Innovative Training. “As soon as you wake up in the morning, grab a glass. Every time you eat, drink a full glass of water before and during bites. The more water you drink, the fuller you will feel, the easier it is to cut back on unnecessary calories. That’s an essential element of weight and fat loss,” she explains. Other trainers concur. “Every chemical reaction in your body needs water,” celebrity trainer and creator of Methodology X Dan Roberts notes. “Even if you’re just mildly dehydrated, that could affect your fat metabolism and your performance in the gym.”
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.

Luckily, that doesn’t mean you need to dedicate even more time exercising. In fact, high-intensity interval training (HIIT) workouts can slash the time commitment while boosting results. HIIT workouts last about 20 minutes and combine bursts of super-intense exercise with slower recovery phases. This type of workout has been found to help people lose more fat once the workout is over, even though they burn less calories during the workout (since workouts are shorter) and also build muscle, rather than break it down the way conventional cardio does.

It’s natural for anyone trying to lose weight to want to lose it very quickly. But evidence shows that people who lose weight gradually and steadily (about 1 to 2 pounds per week) are more successful at keeping weight off. Healthy weight loss isn’t just about a “diet” or “program”. It’s about an ongoing lifestyle that includes long-term changes in daily eating and exercise habits.
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.

●Put tempting foods out of sight, out of mind. We naturally gravitate toward foods that are easiest to reach. So put candy on a high shelf or inside another bag behind something else so you’ll be less likely to go get it, says Cynthia Sass, co-author of “The Flat Belly Diet!” Put smarter choices, such as fresh fruit or popcorn, in bowls where they’re visible and within arm’s reach. Keep a water bottle with you so you won’t have to rummage through the fridge or walk to a vending area to get a drink.
HIIT, or high-intensity interval training, has been called the secret weapon of fat loss. HIIT alternates between short, intense anaerobic exercises, such as sprints, with less-intense recovery periods. This method of exercise raises your heart rate and allows you to burn more calories in a shorter period of time. And if losing loads of calories in a short period of time wasn't enough of a reason, HIIT offers many other benefits as well.
Those trans fats on your menu are hiding out in plain sight and sabotaging your lean belly plans every time you eat them. If a food product says it contains partially hydrogenated oils, you’re eating trans fat, which can increase your risk of heart disease, high cholesterol, and obesity with every bite. In fact, research conducted at Wake Forest University reveals that monkeys whose diets contained eight percent trans fat upped their body fat by 7.2 percent over a six-year study, while those who ate monounsaturated fat gained just a fraction of that amount. Instead of letting harmful trans fat take up space on your menu, fill up with the 20 Healthy Fats to Make You Thin.
When preparing broth, cool it first to remove the fat. Once cooled in the refrigerator, the fat in the broth will solidify on top. Scoop this fat into a separate container and freeze it for later (it’s great for cooking). Reheat the broth to drink the protein-rich, low-fat broth which is filling and nutritious but contains a smaller amount of calories.

Ultimately, weight loss for the long-term requires some short-term behavior change and healthier habit formation. That's why we created our Good Housekeeping Nutritionist Approved Emblem, which exists to help turn smart food choices into healthier eating habits. All GHNA foods and drinks make it easier to find — and eat — good-for-you foods without additional time, effort, and cost. We target the lifestyle-related factors that make healthier eating hard, and find simple but creative solutions that actually work! Look for the emblem on labels wherever you shop for food!
Good news: You might not be as flabby around the middle as you think, says Roberts. “Many people are just bloated,” he says. Focusing on eliminating your bloat can work wonders in terms of achieving a flatter stomach. Some people may need to cut out gluten, while others will see results when they eliminate dairy, he says. And then there are people who without sensitivities who can see results by simply reducing their salt intake and eating foods high in potassium, a powerful mineral that’s been shown help the body rid itself of excess sodium. Bananas, avocados and fresh figs are all potent sources of the nutrient.
Instead of piling everything on one plate, bring food to the table in individual courses. For the first two courses, bring out soup or veggies such as a green salad or the most filling fruits and vegetables. By the time you get to the more calorie-dense foods, like meat and dessert, you’ll be eating less or may already be full. Nothing wrong with leftovers!
Not in an extreme, Atkins sort of way, but having a little protein at every meal fires up your metabolism. "Your digestive system uses more energy to break it down, so you burn more calories," explains Lisa Dorfman, R.D. However, keep protein levels to between 20 and 35 percent of your diet; eating too much of it can cause kidney strain and may cause your body to store too much fat.
If you’ve been eating fast food for years, get real about your approach: You’re probably not going to stick to an organic, gluten-free, paleo overhaul for very long. "You want to change as little as possible to create calorie deficit," says Dr. Seltzer, who insists the best way to support sustainable weight loss is to incorporate small changes into existing habits. So instead of giving up your daily BLT bagels in favor of an egg-white wrap, try ordering your sandwich on a lighter English muffin. Or say you eat a snack bar every afternoon: Swap your 300-calorie bar for a 150-calorie alternative. "Your brain will feel the same way about it, so you won’t feel deprived," he says.

Another popular mainstream diet, Dr. Barry Sears's plan is considered to be one of the first in the recent wave of "anti-inflammatory" plans. It sets you up for success by calibrating your plate to be a third protein and two-thirds carbohydrates (not starchy ones like potatoes, think colorful vegetables instead) with a little bit of MUFAs, or monounsaturated fatty acids (the good-for-you kind ) in the mix.


Stress skyrockets your levels of cortisol, often called “the belly fat” hormone because it signals to the body to store fat around your waist. Add the daily stressors of living our modern lifestyle and you can see how cortisol can be constantly coursing through your veins. This perma-stress mode isn’t good for a lot of healthy reasons, your tummy being just one of them, so it’s important to take time every day to de-stress. Yoga, meditation, walking, journaling, doing a hands-on hobby, or playing a musical instrument are all great time-tested methods. (Hint: Know what isn’t? Watching television. The boob tube actually increases your levels of cortisol!)
