Like a marathoner stretching before the big run, eating half a grapefruit before a meal can enhance your body’s fat-burning performance. A study published in the journal Metabolism found that this “warm-up” tactic can help whittle your middle—by up to an inch—in just six weeks! The scientists attribute the powerful effects to the grapefruits’ fat-zapping phytochemicals. The fruit can interact negatively with certain medications, so as long as you get the green-light from your M.D, plan to have half of a grapefruit before your morning meal and add a few segments your starter salads to reap the benefits.
Keto. Flexitarian. Paleo. Whole 30. Vegan. There are as many diets in existence as there are dangerous weight loss myths. So which eating style should you choose when you’re on a get-fit-quick and have just 10 days? Turns out, numerous studies have found it essentially doesn’t matter which plan you follow for rapid weight loss, be it low-carb or low-fat, as long as you’re eating fewer calories than you’re burning. The key is that it’s sustainable: a strategy that you can keep up for the week and a half—and beyond.

Ranging from just-juice to just-tea cleanses, these typically short-term plans can be dangerous. “Detoxes and cleanses are usually low in calories, protein, and fiber, all nutrients that our bodies need to function,” says Alissa Rumsey, RD, who is in private practice in New York City. “These plans leave you feeling hungry and cranky, causing a rebound food binge once you stop the detox.”


Drinking enough water can help you stay slim, too. Research from the American Chemical Society in Boston found that having two 8-ounce glasses of water before a meal while also reducing portion sizes could help you lose weight and keep it off. Not to mention, water fills you up, curbing your appetite: "In addition to slightly boosting your metabolism, drinking water before meals has been shown to help you eat less without trying," says Sass.

We’ve said it before and we’ll say it again: fat is your friend! To be more specific, healthy fats will be your weight loss friends. Consider adding extra virgin olive oil to your diet and you might see the scale start to tip in your favor. One Journal of Women’s Health study discovered that an EVOO-enriched diet helped participants lose more weight than those on a low-fat diet. Like peanuts and avocados, extra virgin olive oil’s belly-blasting abilities are thought to be a result of the monounsaturated fats it contains.


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.
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.”

When it comes to cravings, protein drinks and bars may also help cure your need for sugar, says Juge. He recommends mixing a flavored protein powder in a blender with as much ice as possible, so it'll taste more like a milkshake. Day Five's protein shake includes a cup of berries, which will also help with sugar cravings. Once or twice per week, Juge adds, you can have a low-sugar, high-protein bar. The newest varieties taste more like candy bars, with state-of-the-art sweetening techniques.
“Bananas contain a small amount of fiber and resistant starch, which have received recent attention for their potential role in boosting weight loss,” says Ellis. Snacking on bananas is easy, convenient, and low cal. They’re also a great source of potassium, which can be lost in sweat during tough workouts or on hot summer days. Plus they make for nice drinks, like the Jamba Juice Triple Revitalizer with carrot and orange juice.

Finally, some chapters I have no problems with! Chapter 6 has some good advice on how to create and use a food diary, and not just to record what you're eating, but to find out what your bad habits are so you can start to recognize them and fix them. I'll be honest, I'm not even aware of the bad habits I have related to how I eat (not just what I eat) and this method is actually good advice on how to achieve it without shaming anyone or making assumptions and generalizations! Chapter 7 is all about stopping food cravings with some great advice. Chapter 8 provides some great advice of creating a physical activity habit (throwing the entire without working out part out the window, but hey, what's a little misleading advertising to get you to open the book. I mean, we already discovered that the whole title was a scam when the author promised to help you lose weight fast yet tells you not to lose weight fast). Chapter 9 provides some decent information about nutrition, though I think this is a far bigger topic than what could be covered in a short chapter of a book.
Yes, you can eat dark chocolate to lose weight. A study among women with normal weight obesity (or “skinny fat syndrome”) who ate a Mediterranean diet that included two servings of dark chocolate per day showed a substantial reduction in waist size than when on a cocoa-free meal plan. Researchers attribute dark chocolate’s weight loss abilities to flavonoids, heart-healthy compounds in the sweet treat that the scientists at Harvard say can reduce the risk of diabetes, heart disease, and mortality. Like nuts, dark chocolate has also been found to induce satiety. When reaching for chocolate, just make sure you choose a bar with at least 70 percent cacao. Anything less contains more belly-bloating sugar and a significantly reduced flavonoid content.
To prep his patients for success, Dr. Seltzer tells them to plan around a large evening meal by eating a lighter breakfast and lunch—NBD since most people who eat a meal before bed tend to wake up feeling relatively full, he says. Research suggests balanced bedtime meals may also promote steady next-day blood sugar levels, which also helps with appetite regulation.
Blueberries are lousy with antioxidants, satiating fiber, potassium, and more, and according to researchers at the University of Michigan, the colorful fruits may also encourage weight loss. In a study of laboratory rats, scientists found that after 90 days the rats who received blueberry-enriched powder as 2 percent of their diet had less abdominal fat, lower triglycerides, lower cholesterol, and improved fasting glucose and insulin sensitivity, than the rats who weren’t given any blueberry-enriched powder.
Both protocols of rapid WL and slow WL caused reduction in waist circumference, hip circumference, total body water, body fat mass, lean body mass, and resting metabolic rate (RMR). Further reduction in waist circumference, hip circumference, fat mass, and percentage of body fat was observed in slow WL and decreased total body water, lean body mass, fat free mass, and RMR was observed in rapid WL. Improvement in lipid and glycemic profiles was observed in both groups. Reduction of low-density lipoprotein and fasting blood sugar, improvement of insulin resistance, and sensitivity were more significant in rapid WL in comparison to slow WL.
If your goal is to lose weight, I would recommend consuming half your body weight in grams of protein a day (at the very least). For those seeking to burn fat and build muscle, aim to consume 0.7 to 1 gram per pound of body weight. For example, if you weight 150 pounds, you should be getting 75 to 150 grams of protein a day (depending on your goals). Checkout this list of these top protein foods.
Caffeine itself may play a synergistic role in increasing metabolic rate. A meta-analysis of 15 studies showed that shows that green tea catechins given with caffeine was able to decrease body weight compared to catechins given alone. I will note that green tea does in fact contain some caffeine, whereas green tea extracts are may or may not contain it. Some studies sugges that regular and high caffeine usage may blunt the benefits of the GTE. In one study, using more than 300 mg/day of caffeine daily negated much of the benefits (a cup of brewed green tea only has 30 mg caffeine). Caucasian population typically drink more coffee and perhaps higher doses of catechins are necessary for benefits.
“The one trick I use now, which I should have been using all along, is the make dinner a no-carb meal. I’ll do a vegan protein and vegetables, and no bread. I think carbs are important and good energy, but when I don’t eat them at night, I wake up and I feel like my belly’s flat first thing in the morning.” — Carrie Underwood, who lost 30 pounds of baby weight in less than a year

Get on with the Mediterranean diet and include some seaweed or Kelp into your meals. Prized for its high levels of iodine, kelp helps to create the thyroid hormones in your body. These regulate your metabolic rate – the rate in which your body burns fat. It also contains several minerals which have been found to assist the breakdown of belly fat and relieve water retention. Seek it out in Japanese supermarkets or pick up from health food stores in a supplement form.

Sleeping for more than five hours a night might seem like a luxury for some, but it can have a serious impact on your overall health. Not getting the recommended 7-8 hours of shut-eye a night puts you at risk for fatigue the next day, which means you’re more likely to crave and snack on high-calorie comfort food. Try to go to bed sooner so you can get a little more sleep, which will help you eat less. And to blast fat even faster, don’t miss these essential 55 Ways to Boost Your Metabolism. 

Plain and simple: We just don't feel full by liquid calories in quite the same way as we do real food. Drinking a juice or caramel coffee drink, for instance, won't make you feel full the way eating a bowl of veggie- and protein-packed stir-fry will. So monitor your intake of juice, soda, sweetened coffee and tea, and alcoholic beverages. If you consume each of those beverages during the day, you'll have taken in at least 800 extra calories by nighttime — and you'll still be hungry. (Incidentally, alcohol may suppress the metabolism of fat, making it tougher for you to burn those calories.) Some other ways to skip sugar? Check 'em out here.

Eat at least 1g of protein per pound of bodyweight, daily. If your protein intake is too low on a restricted-calorie diet, you'll lose a lot of muscle in addition to any fat you're lucky enough to shed. A high-protein intake will help you preserve lean mass during your dieting phase. Choose lean, high-quality proteins like egg whites, poultry, lean red meat, and protein supplements. The diet provided here contains about 220-250g of protein daily, fine for a male weighing 200-250lbs. Up your protein only if you're heavier than 250lbs, or you're very hungry and need to add food during the day. Juge suggests an additional protein shake for an easy quick fix. (If you're under 180lbs, cut out 3oz of meat or chicken per day from the diet.) 

Before you start the meal plan, make a pot of the Veggie Soup. Make 2 servings of Overnight Oats, so they can soak in the fridge. It’s also super helpful to prep your veggie snacks—make 4 bags filled with baby carrots and sugar snap peas, and 3 bags filled with broccoli and cauliflower, for alternate days. And if you really want to get ahead, you could also grill the chicken breasts and cook the quinoa and brown rice in advance.
“The American Heart Association recommends that men eat less than 36 grams of added sugar and that women consume less than 24 grams. However, for optimal weight loss, I tell my male clients to consume less than 20 grams of sugar per day and I tell the women to consume less than 15 grams.The easiest way to cut back on the sweet stuff is by consuming less sugary drinks and dressings. Cut the sugar, lose the fat, regain your health and life.” — Dr. Sean M. Wells, DPT, PT, OCS, ATC/L, CSCS
I am skilled at losing 50 pounds in the slow and steady method, I have proven that rapid weight loss is doable if you focus on end results. I have lived everyday since March of 2006 with the knowledge that my escape from morbid obesity is fleeting as the blanket of low lying fog on a beautiful fall morning. If I don’t pay attention I will never know the moment it faded away. My workouts are the time I “sit and take in the beauty” it brings to every moment of my life. 

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 38 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.
Salmon is a rich source of high-quality protein and provides plenty of "good" fats: omega-3 fatty acids. A diet rich in omega-3 fatty acids helped people feel more satisfied when they were watching their calories, per a study in Appetite. Eating salmon can be a delicious and versatile way to get your recommended two weekly servings of heart-healthy fish. 

A squeeze of lemon adds instant freshness to everything from drinks to salads to fish without additional calories, making it an ideal way to flavor food if you're watching your weight. Plus, the pectin fiber in lemons can help fill you up and fight off hunger cravings. And while it hasn't been scientifically proven, some experts believe that the citrus fruit can aid in weight loss, as well.
“You can’t just say, ‘I want to lose weight…someday.’ It’s that kind of loose talk, without a fence or guideline, that discourages you from getting started and prevents you from succeeding. The way I did it was by tying it to an upcoming event in my life. I never focused on a number and I didn’t set out to lose a certain number of pounds per week or overall. I merely found a target date a year away and I proclaimed to myself that I’d be in better shape by then. — Maria Menounos, author of  The Everygirl’s Guide to Diet and Fitness, on how she lost 40 pounds
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.
Getting enough protein every day, whether you’re in a quick-fix or long-term mindset is important for keeping your muscles and metabolism healthy throughout weight loss. Make sure you’re having some chicken breast, lean ground turkey, fish, seafood or tempeh that’s the size of a deck of cards at every meal. When snacking, have 2 eggs, 1/4 cup of nuts, or 3/4 cup of Greek yogurt or cottage cheese to meet your protein needs and stay full and feel slim.
We’ve said it before and we’ll say it again: fat is your friend! To be more specific, healthy fats will be your weight loss friends. Consider adding extra virgin olive oil to your diet and you might see the scale start to tip in your favor. One Journal of Women’s Health study discovered that an EVOO-enriched diet helped participants lose more weight than those on a low-fat diet. Like peanuts and avocados, extra virgin olive oil’s belly-blasting abilities are thought to be a result of the monounsaturated fats it contains.

In the 2016 randomized, placebo controlled trial, researchers used a fairly high dose of EGCG of 856 mg, which required high dose green tea extract (GTE). Trying to drink this much from hot brewed green tea is daunting as it would require 12 cups per day. Supplements have high placebo effects, so randomization and placebo controlling is important. If people believe a supplement will make them lose weight, it generally will, no matter what it is. In order to maximize extraction of EGCG, the GTE was prepared by steeping green tea leaves in pure water at 90 C three times for 20 minutes each, then cooling the extract to preserve the catechin content. The extract was dried under low temperature and pressure conditions and also decaffeinated.


Although it’s tempting to look for a quick fix with a speedy weight loss scheme, many popular diets are unhealthy or produce only temporary results. You’ll have better luck with an eating plan that includes a variety of healthful foods and gives you enough calories and nutrients to meet your body’s needs. Taking it slow by making ongoing eating and exercise changes is the best way to reach and maintain your optimal weight.
Lipton green tea is loaded with epigallocatechin gallate (EGCG), a catechin that is found in green tea. It helps your body to burn fat and increases your body’s insulin sensitivity (3). EGCG has also been found to inhibit fatty liver disease in lab rats (4). If you are a beginner, then the green tea containing honey and pomegranate is a better option for weight loss. But all the variants have the same impact on your body. 

Still, when it comes to losing weight, working a few cups of brewed green tea into your diet isn’t necessarily a bad idea. “Like coffee, green tea may give you a mild boost, and if you don’t add sugar, it has no calories,” notes Consumer Reports’ chief medical adviser, Marvin M. Lipman, M.D. “So drinking it in place of sugary drinks such as soda can help you cut calories.” 
Salmon boasts significant anti-inflammatory properties thanks to its rich omega-3 fatty acid content, meaning it’s an excellent source of protein for those looking to jumpstart their weight loss. In fact, one study that examined the effects of weight loss and seafood consumption showed wild salmon to be the most effective at reducing inflammation—better than lean white fish and a fish-free diet. According to a study published in The Journal of Nutritional Biochemistry, fishy fatty acids may also signal thyroid cells in the liver to burn more fat.
The number of calories you need on a daily basis to lose weight depends on an array of factors, including age, gender, height, genetics, and level of physical activity. Generally, your daily calorie intake shouldn’t fall below 1,200 calories; any less than that threshold can be dangerous in the long-term. Plus, since we get about 20 percent of our fluids from food, this can also increase your risk for dehydration.
“Stop focusing on calories and start focusing on the quality of the foods you eat. High-quality diet options are natural, whole, minimally processed foods, like vegetables, fruits, nuts or seeds that offer a lot more nutritional value in the form of vitamins, minerals, healthy fats and fiber. These foods help tame hunger naturally and nourish our cells at the deepest level so that we aren’t left with constant cravings. — Michelle Loy, MPH, MS, CSSD, Registered Dietitian Nutritionist and owner of Go Wellness in Orange County, California

Bonus: Save money by choosing meals that use in-season produce and combining your meals with your local grocery store’s sales flyer. And don’t forget about leftovers! Use them to create new meals (for instance, make a stir-fry with leftover cooked meats and veggies) or have a weekly night where all the leftovers get put out and everyone in the family can eat their favorites again.

“If you’re feeling deprived by your diet, build in a cheat meal at least once a week in which you can indulge guilt-free. Doing this will help you avoid viewing certain foods as ‘off limits,’ which will help you crave them less.” — David Zinczenko, author of  Zero Belly Cookbook: 150+ Delicious Recipes to Flatten Your Belly, Turn Off Your Fat Genes, and Help Keep You Lean for Life!

One easy trick if you're a pasta fan is to swap out white pasta for the wonderfully named courgetti (spaghetti made from spiralizing courgette). You’ll hardly notice the difference when you’re eating it, but you’ll be fuller for longer despite consuming fewer calories. When you consume fewer calories, your body can go to your fat reserves for energy, rather than just burning off the food you’ve eaten.  


Fiber is nature's weight loss aid. It comes in two forms, soluble (the gummy type found in oatmeal and beans) and insoluble (the type found in fruits, vegetables, and whole grains). Both are important to good health. Soluble fiber can help to lower cholesterol; insoluble contains indigestible fibers that add bulk to our diets. Both forms of fiber swell in the stomach and help to create a feeling of fullness. Most high-fiber foods are also high in water and low in calories, making them must-have diet foods.
You don’t need to bust out the measuring cups to properly portion out your food: A serving size of meat is roughly the size of a deck of cards or the size of the palm of your hand. Your entire fist should be the size of a serving of veggies (although the more, the better!). A serving of fat, such as butter or coconut oil, should be the size of your thumb. Your carb serving should be no bigger than what can fit in your cupped hand. For other ways to eyeball your proper serving sizes, check out What the Perfect Food Portion Sizes Actually Look Like.
Speaking of standout breakfast foods, Greek yogurt is another option worthy of the spotlight thanks to its high-protein content. Per study in the journal Appetite, researchers from the University of Missouri compared the satiety effects of high-, moderate-, and low-protein yogurts on women aged 24-28, and found Greek yogurt, with the highest protein content, to have the greatest effect. What’s more? Probiotics in items such as yogurt and fermented foods, like pickles and sauerkraut, help good bacteria in the gut process food more efficiently. Hello, weight loss! If you want to get even more protein in your yogurt, check out Icelandic yogurts, which can have two to three more grams of protein per serving compared to Greek.
