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.

It comes on suddenly: One minute you’re feeling great and the next you’re starving for a snack. Skip the vending machine and prepare your own healthy snacks to take to work, school or whenever you’re out and about. Why? In part, because most processed snacks are purely carbs and are the definition of empty calories, jacking your blood sugar and leaving you hungrier afterwards.
There are so many protein powders on the market, and sometimes it can be hard to decide which one is best for your weight-loss goals. But by swapping out a whey or creatine powder for something plant-based, you could cut down on belly fat. Although whey powder is chock-full of muscle-boosting protein, it can also cause a belly bloat. Instead, try one of the 100+ recipes in Zero Belly Smoothies, made with vegan protein that will still have the same muscle-building, fat-burning, and satiating effects, just without the bloat.
Many variations of this eating style exist — ranging from fasting for a number of hours each day up to an entire 24-hour fasting period one or two times a week. “If you're trying to kick a habit like eating late into the night, then stopping eating earlier in the evening and fasting overnight could be beneficial for you,” says Hultin. “There are many types of intermittent fasting, so ensuring you pick one that works for you and your lifestyle is important.”
Whatever you choose for lunch—a salad, sandwich, grain bowl—top it with some avocado (or guac!). The creamy green 'cado offers some serious health perks. In a review published in 2017 in Phytotherapy Research, researchers looked at the effect avocado-eating can have on reducing metabolic syndrome, a group of risk factors that raises your risk of heart disease, diabetes and stroke. They concluded that eating avocado daily can play a role in reducing blood pressure, lessening diabetes risk, keeping arteries clear and, yes, helping with weight loss. Avocados contain antioxidants like carotenoids, vitamins and fatty acids, as well as other plant compounds that may affect the hunger hormone leptin to help keep you satiated and help curb your appetite to sidestep over-snacking.
Some green tea varieties are better for weight loss than others. If you’re all about that green and on a weight-loss mission, you might want to choose Matcha green tea—the richest green tea source of nutrients and antioxidants. Registered dietitian Isabel K Smith explains why: “The whole leaf is ground and consumed as part of the beverage, as opposed to other (most) types of green tea where the leaves are steeped and then the tea is consumed.”
In the first phase of the study, 50% of people on the gradual diet and 81% of people on the rapid diet achieved the 12.5% weight loss goal. Both groups struggled considerably in the second phase: 71.2% in the gradual diet group and 70.5% in the rapid diet regained most of the weight they had shed in the first phase. In both groups, patients who successfully completed phase 1 lost a little over 14 kilograms in the first phase but then gained back all but 4 kg in the second phase.
Also known as yam or yambean, this Mexican turnip is a great source of fiber, says Dr. Jaime Schehr, a registered dietitian in New York City. “This plant is great for weight loss due to its high fiber to sugar ratio (a whopping 32g of fiber per medium jimaca—that’s almost an entire day’s worth). They are also a good source of potassium, an essential mineral in maintaining water balance in our body.”
Skip the cream and sugar in your cup of joe, and opt for it black to help you lose weight fast. Black coffee has zero calories, and it can help you burn calories faster. According to a study published in the journal Physiology & Behavior, the average metabolic rate of people who drank caffeinated coffee was 16 percent higher than that of those who drank decaf.
Green tea’s health benefits stem from its high antioxidant content. Antioxidants are chemical compounds that can protect our cells from damage and may help protect us against cancer and heart disease. Green tea contains a variety of antioxidants including catechins, theaflavins and the flavanol quercitin. Green tea also contains caffeine, about 25 mg per 8 oz. cup, which is about one-third the caffeine in an 8 oz. cup of coffee.
HIIT stands for high intensity interval training, and it’s a great way to build muscle without spending hours in the gym. The idea is to go all out for a short period of time, followed by a slower pace that allows you to recover. Think of jogging or sprinting all out for 30 seconds, followed by a minute or two of rest, then repeat. Short bursts of high-intensity exercises keep your heart rate up while adding lean muscle. More muscle mass equals calories burned on a daily basis. Also, the more lean muscle you have, the higher your metabolism is.
On test days, they were fed either the control meal or the same entrées but altered so that calorie density was reduced by 20% using one of the three strategies. Entrée portion sizes were large enough so that the subjects could consume as much as they desired of the test meals. Leftovers were weighed to determine precisely how much was eaten of each of the test meals.
The results of the current study showed that both protocols of rapid WL and slow WL caused a reduction in waist circumference, hip circumference, total body water, body fat mass, FFM, LBM, and RMR. Greater reduction of waist circumference, hip circumference, and FFM was seen with slow WL and greater reduction of total body water, LBM, and RMR was seen with rapid WL. It seems that the effect of slow WL in maintaining body water and LBM (as a metabolic tissue) was more significant than rapid WL.
So while green tea might not be the lean fat-burning machine it's cracked up to be, that doesn't mean it can't be beneficial for weight loss. After all, unsweetened green tea is one of the smartest beverage picks around. It’s free of calories, fat, and sugar—definitely much better than a 140-calorie can of soda. And since it's common to confuse thirst for hunger, sipping some green tea can help keep food cravings at bay.
Dr. Shiel received a Bachelor of Science degree with honors from the University of Notre Dame. There he was involved in research in radiation biology and received the Huisking Scholarship. After graduating from St. Louis University School of Medicine, he completed his Internal Medicine residency and Rheumatology fellowship at the University of California, Irvine. He is board-certified in Internal Medicine and Rheumatology.
While they may not be the most appetizing item on the list, if you can stomach them, pop open a can of sardines this summer! Sardines are full of fat-fighting compounds that help stabilize blood sugar. They’re rich sources of CO enzyme Q10, vitamin B12, selenium, omega-3 oils, calcium, phosphorus, and vitamin D. Plus, sardines are satiating and packed with protein, says Richter.

“Before you begin to change your diet, spend a week recording everything you eat—and I mean everything. Before I made any changes to my diet, I journaled everything I ate each day for a week, including little things like gum or breath mints. If you have a piece of candy from your coworker’s desk, snag a few spoonfuls of your boyfriend’s ice cream, or finish the few bits of grilled cheese your kid left on her plate, write it down! It all adds up, and you just don’t realize how much you’re eating until you actually see it all on paper in front of you. I, for one, was stunned.” — Maria Menounos, author of  The Everygirl’s Guide to Diet and Fitness, on how she lost 40 pounds


To transform your body, to get fit, to be healthy and to feel great you gotta exercise. Just like the air you breathe, your body needs physical exercise. And it needs exercise in a way that is so far-reaching that scientists are only just starting to unravel some of the amazing effects exercise has on our bodies. Did you know, that exercise can actually reprogram your DNA? And while you may think that by not doing exercise you’re not doing any harm, lack of exercise itself can alter your DNA – but unfavourably!


Another healthy change that will help you look better is to cut back on salt. Sodium causes your body to hold onto excess water, so eating a high-salt diet means you’re likely storing more water weight than necessary. Check to see if you have any of the seven clear signs you’re eating too much salt. If you’re in a rush to lose weight fast, cut out added salt as much as possible. That means keep ditching the salt shaker and avoiding processed and packaged foods, where added salt is pretty much inevitable.

I just read your piece on weight loss rated rapid vs slow and steady. I am a veteran with decades of experience. I have successfully lost 143 pounds in 2001 with what is known as the vlcd program. I spent from March 31,2001 until November of 2001 with 700 calories average daily intake. I came out at a healthy weight but not mentally prepared to deal with the aftermath of a completely morphed body image. I could not wrap my brain around what had transpired in 6 short months. I still saw the 333 pound woman when I looked in the mirror. I still caught myself looking in the plus sized clothing section. There are as many factors that cause morbid obesity as there are programs offering the “cure”
Already nearly calorie free, matcha is a great addition to a weight loss program by tackling the problem from both sides. It boosts metabolism and burns fat. One recent study even suggested that matcha may help burn calories by four times. At the same time, matcha does not put any stress on the body. It doesn’t raise blood pressure or heart rate, making it a safe alternative to questionable quick fixes or pharmaceuticals ridden with side effects.
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.

Coffee jumpstarts your metabolism, making the non-decaf stuff a worthy weight loss ally. According to a study published in the journal Physiology & Behavior, the average metabolic rate of people who drank caffeinated coffee was 16 percent higher than that of those who drank decaf. In addition to caffeinating your coffee, it’s also crucial to keep it black and avoid adding any unhealthy creamers and artificial sweeteners, both of which are enemies of weight loss.
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.
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.
“I tell all of my celebrity and professional-athlete clients to get between 6 and 8 hours of sleep per night. Everyone is overly focused on food, water and exercise, all of which are extremely imperative to weight loss and optimal health. However, without proper sleep, all of these the other factors are null and void. When you don’t get enough sleep, levels of the hormone leptin drop, which increases appetite. This surge in appetite makes comfort food more appealing, which can derail weight loss efforts.” — Jay Cardiello, celebrity fitness and nutrition expert
“A pound of carrots will fill you up, with only a smattering of calories -- or you can have a pound of cheeseburger, and you’ll gain weight faster than you can jump on a scale,” says Elizabeth Somer, MA, RD, author of 10 Habits That Mess Up a Woman's Diet and Age-Proof Your Body. “People don’t gain weight on carrots and blueberries; it would be almost impossible to eat enough of them,” Somers says. “We fill up on the volume of food.” 

Australian researchers randomized 204 obese adults to either a 12-week rapid weight loss diet (with Nestlé's Optifast) or a 36-week gradual diet. A weight loss of 15% was the goal of both diets. Participants who lost at least 12.5% of their weight then participated in the second phase of the study, in which they were placed on a 144-week maintenance diet.
Like protein, fiber slows the rate at which your body plows through carb calories so you feel full for longer and maintain steadier blood sugar levels, one reason why research consistently links fiber intake to weight loss. That means fibrous whole grain bread tends to be a better choice than white bread and also explains why fruits, which contain fiber and valuable vitamins in addition to sugar, beat straight-up candy every time.
Research considers have appeared, as per Consumer Reports, that green tea raises metabolic rates. These rates are what individuals allude to when they say somebody can eat a great deal of nourishment without putting on weight, since they have "an elevated ability to burn calories." The rate alludes to what number of calories are scorched by your body as opposed to put away as fat cells. Green tea is said to raise these rates through a mix of caffeine and catechins, which are cell reinforcements that are likewise found in follow amounts in red wine and dim chocolate.
Sure, you certainly need to drink plenty of water to help expedite the process of ridding your body of excess sodium, you can (and should!) also consume high-water content foods. Reach for cucumbers, tomatoes, watermelon, asparagus, grapes, celery, artichokes, pineapple, and cranberries — all of which contain diuretic properties that will also help you stay full due to their higher fiber content.
The results of the current study showed that both protocols of rapid WL and slow WL caused a reduction in waist circumference, hip circumference, total body water, body fat mass, FFM, LBM, and RMR. Greater reduction of waist circumference, hip circumference, and FFM was seen with slow WL and greater reduction of total body water, LBM, and RMR was seen with rapid WL. It seems that the effect of slow WL in maintaining body water and LBM (as a metabolic tissue) was more significant than rapid WL. 

“Preliminary evidence suggests that if someone is already eating a low-fat, portion-controlled diet and then they get three servings of nonfat milk a day, they lose more weight than someone who eats the same number of calories but doesn’t have the milk,” Somer says. The theory is that calcium may inhibit the storage of fat, and it seems that the weight loss comes largely from the midsection.

Kefir is a yogurt-like substance, but it actually contains less sugar and more protein than conventional yogurt while remaining packed with gut-friendly probiotics that can help you lose weight by aiding digestion. In one study, kefir displayed weight loss properties similar to those of milk and other dairy-rich products. Other probiotic-rich foods include kombucha, bone broth, and fermented items such as sauerkraut and kimchi.


Why not empower rice, quinoa and even oatmeal with the belly-fat burning properties of green tea? Tie 4 green tea bags onto a wooden spoon. Fill a small pot with 2 cups water; add wooden spoon and tea bags. Bring water to a boil and remove tea bags. Add the grains to the boiling tea water and cook as directed. Try it with these delicious Quinoa Recipes for Weight Loss!
A fat-burning superfood, grapefruit contains a compound that can lower the fat-storage hormone insulin, which in turn can lead to weight loss. In fact, eating half a grapefruit before each meal could help you lose up to a pound a week—even if you don't change anything else about your diet. Because grapefruits are 90% water, which fills you up, they also act as a natural appetite suppressant.
“Use a VersaClimber or take a VersaClimber class. These machines are still not that common, but in my opinion they are far more effective for weight loss than other forms of cardio. They require you to use a large portion of your muscles and it’s functionally better for you than other forms of cardio like spinning. Everyone is talking about Rise Nation in LA at the moment as they are the first dedicated VersaClimbing studio. There’s no harder cardio workout I have tried. To lose fat you have to put in the work. — Dan Roberts, celebrity trainer and creator of Methodology X
A new player in the weight loss program space, Noom packs a lot of behavioral psychology into one sophisticated app. It aims to help you identify and break bad habits, and have some fun doing it. The powerful app echoes Weight Watchers’ successful community approach, but outleagues that program in terms of learning resources. While it’s the more expensive of our two favorite programs, it’s the richer when it comes to virtual experience — with personalized lessons, tasks, and support that made us look forward to opening up the app.
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.

“It’s far more difficult to eat a healthier diet and fit in exercise if you don’t plan ahead. Plan out your meals for the week ahead and go grocery shopping over the weekend to ensure you have the ingredients you need on hand. If you can, do some meal prep in your down time—cut fresh veggies, marinate your protein, cook up a batch of whole grains in advance. When you’re prepared you’re far less likely to order takeout. — Jessica Fishman Levinson, MS, RDN, CDN, culinary-nutrition consultant and founder of Nutritioulicious


Kimchi is a spicy Korean condiment that's made with fermented cabbage and is a great source of vitamins A, B, and C. Because it's fermented (like sauerkraut), kimchi contains tons of those good probiotics that aid the body in digestion. A recent study in the Proceedings of the National Academy of Science found that maintaining healthy bacteria in your gut can improve gut lining, which in turn could help reduce fat mass and inflammation.

“Whether it’s an app or paper food logs, tracking what you eat will certainly be eye-opening. Almost everyone consumes more than they think. Write everything down as soon as you’re done eating so you don’t forget anything. The simple act of recording what you eat will make you eat less. When the calories are in your face, it makes you think twice!” — Martha McKittrick, RD, CDE
If you’re dropping weight quickly in an unhealthy manner, you may be putting yourself at risk of malnutrition, a condition in which you’re not eating enough calories or micronutrients (e.g. vitamins and minerals) — or both. If your diet isn’t balanced with the proper amounts of carbs, protein, and healthy fats, you’re probably not eating enough of the nutrients your body needs to thrive.
Here’s the full shopping list for exactly what to buy, and check to make sure you have a few pantry staples on hand. Morris recommends starting on a weekend, so you can make a big pot of veggie soup, and give your body a chance to adjust before diving into a busy week. Her plan cuts carbs for the first couple of days, before slowly reintroducing whole grains. And if you want to mix it up, there are lots more options for healthy snacks, just make sure to get a serving of fruit or vegetables, along with protein.
Studies on green tea’s impact on cancer have been mixed. But green tea is known to aid healthy cells in all stages of growth. There are some clues that green tea may help destroy cancer cells, but that research is still in its early stages, so you shouldn’t count on green tea to prevent cancer. In fact, the National Cancer Institute's web site says it "does not recommend for or against the use of tea to reduce the risk of any type of cancer."
At first, Samantha says she hated the bitter taste and had to force herself to drink it. But soon, Samantha was sipping on green tea and lemon every morning. She then began drinking one cup each hour at work and finished off the day with one while watching TV—a total of nine cups of green tea every day. After just one month of this regimen, Samantha dropped nearly 15 pounds.
Also, men tend to lose weight where they need it most (read: belly), so it's often more immediately noticeable when overweight men start trimming down than when women do, as ladies' fat stores are typically more spread out, which is partly why they tend to lose weight at a slower pace than guys. Even basic, regular exercise -- ideally 30 to 60 minutes a day -- tends to reduce abdominal obesity, even if guys don’t technically lose weight.
