This popular diet program is fairly restrictive — and for the first 30 days, dieters must cut out dairy, grains, legumes, most dairy, added sugar, and alcohol without any slip-ups, according to the Whole30 website. (29) The aim is to “reset” your body and to adopt dietary habits resulting in weight loss. Cutting out added sugar and alcohol has merit, but all the restrictions prove challenging and could lead to nutrient deficiencies and disordered eating.

“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
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.
“Anytime you’re stressed, you probably go for food,” Dr. Seltzer says. (Have we met?!) That’s because cortisol, the stress hormone, stokes your appetite for sugary, fatty foods. No wonder it’s associated with higher body weight, according to a 2007 Obesity study that quantified chronic stress exposure by looking at cortisol concentrations in more than 2,000 adults’ hair.
Consequently, researchers have widely discredited the hCG diet, which involves using hCG injections, pellets, sprays, or drops, and consuming  as few as 500 calories daily. The diet is problematic not only because there’s a lack of research on hCG supplements, but also because  the calorie requirement is dangerously low, potentially leading to nutrient deficiencies, fatigue, hormone imbalances, blood clots, and other issues. Thus, most experts agree the hCG Diet is not safe for anyone, the Mayo Clinic notes. (35)

Stopping eating after dinner is an easy way to easily cut back on mindless munching and extra calories, and can help boost weight loss, White says. One way to prevent that post-dinner grazing is to brush your teeth almost immediately after your last meal of the day. The minty flavor in your mouth will make all your favorite foods taste gross anyway, and you won’t want to go back and brush your teeth all over again.
“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

“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
Spoon Guru nutritionist Isabel Butler (MSc, ANutr) recommends that “the best way to reduce weight and maintain the weight loss is by simply eating a balanced and healthy diet, without refusing yourself particular foods… If you do cut out foods, you need to make sure your diet is still balanced and you are getting the nutrients your body needs from other sources.”  
One of the easiest ways to burn some extra calories is to get up from your chair at work; standing burns 50 more calories per hour than sitting, according to a British study. If you are lucky enough to have a standing desk, make sure you utilize it. If not, you can easily make your own by stacking books or boxes on your desk and standing up to work. At the very least, make sure you’re taking a break every hour to stand up and stretch, and possibly go for a walk around the office. Every bit of movement counts!
With this in mind, we’ve put together a list of 40 foods that have been proven to jumpstart weight loss and will help you get to your ideal physique. To jumpstart your weight loss, we’ve selected some nutritious eats, like salsa, that are lower-calorie substitutes for less healthy choices (we’re looking at you, ketchup). And others, such as watermelon, contain certain compounds that have been scientifically proven to reduce the size of your waist and help reduce body fat. Scroll down below for a list of a few dozen weight-loss wonders, and get even more health-conscious inspiration from this list of the 40 Things Healthy Cooks Always Have in Their Kitchen!
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.

Another win for your morning cup of joe: Caffeinated coffee keeps things moving through the digestive tract. Since staying regular is key to a tighter-looking tummy, drinking about 8 to 16 ounces of java at the same time every day can help you stay on schedule. Remember: Sugary drinks can lead to weight gain, so skip fancy flavorings and synthetic sweeteners containing sugar alcohols, which can cause bloating.

Buy an iced tea maker. During warmer months, drinking hot tea may not sound like fun; however, you can still consume just as much tea by using an iced tea maker. Like the electric teakettle, simply fill the machine with water; add ice (according to the manufacturer’s directions) and teabags. Turn it on and begin drinking fresh iced tea in a matter of minutes.
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.”
“Eat vegetables before or with meals. Whether you are hungry on your way home or right when you walk in the door, snacking on veggies can help you keep your portions in check once you sit down to a meal. I also recommend starting your dinner with a vegetable salad or vegetable soup to fill you up and prevent overeating. — Ilyse Schapiro, MS, RD, CDN, author of  Should I Scoop Out My Bagel?
In previous studies, elevated ratio of myostatin-to-follistatin, as an indicator of skeletal muscle catabolism, was reported to be greater in rapid WL compared to slow WL (25). The results were consistent with other studies in this field (26). In a study by Martin et al., the impact of these 2 protocols had been compared on the indices of anthropometric and lipid profiles. Their study was conducted in the form of a pilot study on obese postmenopausal females. The results of their study showed that slow WL caused more fat mass reduction and less FFM loss. However, in their study, no differences in lipid profile were observed between slow WL and rapid WL (18).

Rise and shine—literally! Researchers from Northwest University found that people who were exposed to bright daylight earlier in the day tended to weigh less than those who didn’t get sunlight until later. So right after you wake up, open the blinds and let the sunshine in. Or better yet, step outside and enjoy your morning cup of coffee on the front porch
The concept of "diet" tea is sort of false advertising -- any unsweetened, natural tea can promote weight loss. Certain teas may act as a laxative or fat-blocker and that's why they're marketed as such. However, laxatives just clean out your colon (you've already consumed the calories). You may lose a little bit of water weight initially, but the second you drink something, it'll come back.
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.
Giancoli also recommends finding a diet that fits in with how you really live. She notes that if you enjoy going out to eat but try to commit to a diet that forbids you from ever going to a restaurant, you’re just going to cheat. “It’s not sustainable… You’re most likely going to have a healthier meal if you’re going to cook yourself, but you’re depriving yourself of that social interaction if you never go out.” To put it another way: Your eating practices shouldn’t isolate you or keep you from having fun.
Even at large doses, the effect of green tea for weight loss is minimal. For example, in a study published in the journal Clinical Nutrition in 2016, overweight women took either a daily dose of about 1,350 mg of green tea extract in supplement form (the equivalent of roughly 15 cups of green tea) or a placebo for 12 weeks. Though the green tea group dropped an average of 2.4 pounds, the women taking the placebo lost 4.4 pounds.

The active compounds in green tea aids in the process of breaking down fat in the fat cells, thereby moving them into the bloodstream. Hence, we can conclude that green tea contains bioactive substances like caffeine and EGCG, which have powerful health impacts. They mobilise the movement of fat content into the fat cells thus making it easier for them to produce energy, and releasing it throughout the body to be used by other cells.
“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
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! 

At any given time, there are dozens of weight-loss hypes in the marketplace that claim to take off 10 pounds in 10 days, or whatever. Desperation can tempt us to try anything — from "clean eating" to cutting out food groups entirely. Keep in mind: Just because an avocado-walnut-"crunchy"-kale-salad dripping in coconut oil is deemed "clean" by a so-called "expert" on your Instagram feed does not make it an unlimited food. Moral of the story? Avoid fads, eat real food, watch some Netflix, and unwind (perhaps with a glass of wine in hand). Now that's my kind of detox.
“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
Do you mindlessly sprinkle salt on your food without even tasting it first? Stop it! Seriously. Extra sodium can lead to water weight gain and bloating, which will make your pants fit tighter (and the number on the scale tick up). Be sure to read your labels, too; sodium is typically lurking in in processed foods, even “healthy” ones like frozen dinners and canned soups.
Going gluten-free may be a popular trend, but unless you're actually gluten-intolerant or have celiac disease, plenty of reasons exist to continue eating whole grains. They're a tasty way to fill up on both soluble and insoluble fiber, which help you feel full for longer and keep bowel movements regular (oats, barley, and bulgur are especially high sources). Whole grains can also help prevent weight gain: in one study, women who ate whole grains like wheat germ and dark bread had a 49% lower risk of "major" weight gain over time.
Diets don't work. There are hundreds of diets that will help you lose weight, but what good is losing weight if you gain it right back? Eating crazy food combinations or eliminating food groups is not the way to keep weight off. Instead, choose a nutritionally balanced plan with enough calories to keep you from feeling famished (like the WebMD Weight Loss Clinic eating plans).
Giancoli also recommends finding a diet that fits in with how you really live. She notes that if you enjoy going out to eat but try to commit to a diet that forbids you from ever going to a restaurant, you’re just going to cheat. “It’s not sustainable… You’re most likely going to have a healthier meal if you’re going to cook yourself, but you’re depriving yourself of that social interaction if you never go out.” To put it another way: Your eating practices shouldn’t isolate you or keep you from having fun.

After analysis, researchers found that adults following the rapid weight loss program were more likely to achieve weight loss goals compared to those on the gradual program. In fact, 81% of participants in the rapid weight loss group achieved weight loss goals, compared to just 50% of the gradual weight loss group. And contrary to current beliefs, there was no significant difference in weight regain in either group after three years. Three years after the initial diet, nearly three-fourths of all participants regained the weight they lost, regardless of their diet.
Putting aside all the complicated, scientific reasons to exercise, exercise offers benefits that dieting just can’t. Exercise allows you to boost your metabolism and turn your body into a fat blasting furnace. Exercise builds muscle in the places you want, improves body shape and gives you a firm, toned body. Dieting, on the other hand, doesn’t promise a firm body – you can lose weight dieting and still be jiggly! And of course, in conjunction with diet, exercise speeds up the whole weight loss process, and who doesn’t want that?
A significant reduction in body fat (fat mass (FM), Body fat percentage, Arm fat percentage, feet FM, feet fat percentage) was observed in the slow WL group compared to the rapid WL group. In addition, a significant reduction in lean mass (lean body mass (LBM), fat free mass (FFM), Trunk lean) and total body water and RMR was seen in the rapid WL group compared to the slow WL group.
Green tea is widely consumed and associated with a number of health benefits, including decreasing risk of heart disease and certain types of cancer. It's also used to help reduce inflammation for those with inflammatory bowel disease and may aid in blood sugar control in people who suffer from diabetes. And when consumed as a beverage, green tea is considered safe.
Whether you track how many inches you’ve lost, keep a food diary or maintain a journal about the healthy changes you’ve made, it’s encouraging to see what a great job you’re doing! Bonus: Keeping an exercise or food diary can help you see weaknesses in your routine, push yourself out of a fitness plateau or notice what situations drive you to eat more or exercise less.
One study claimed that people who consume green tea regularly lost an average of 2.9 pounds over 12 weeks, without making any changes in their diet, reported express.co.uk. It has been shown that the combination of flavonoid, also known as called catechin, and caffeine in green tea also increases the amount of energy the body uses. While green tea itself offers a host of health benefits, adding a dash of freshly squeezed lemon juice to your green tea will make an excellent detox drink that will help your body to expel toxins as well as provide you with the nutrition you need without bloating you up. It has no calories but packed with metabolism-boosting properties. Read: Drinking this delicious mix everyday will shrink your belly in a week
That said, carrying extra weight around the middle is also tied to increased heart risks, making it arguably unhealthier to be an overweight man than a plus-size woman. Big bellies, it turns out, are a sort of a double-edged sword when it comes to weight loss: They're an extra health risk for men, but give guys the edge when it comes to dropping pounds.
Be wary of supplements with ingredients like yohimbe, Garcinia cambogia, guar gum, and hoodia. For these, there’s more evidence of negative side effects than weight-loss effectiveness. It’s possible to lose weight with supplements containing these ingredients, but it may be because the adverse effects, which include GI-related issues like diarrhea, nausea, and vomiting.
Don't get me wrong — exercising at any time is good for you. But evening activity may be particularly beneficial because many people's metabolism slows down toward the end of the day. Thirty minutes of aerobic activity before dinner increases your metabolic rate and may keep it elevated for another two or three hours, even after you've stopped moving. What that means for you: You're less likely to go back for seconds or thirds. Plus, it'll help you relax post meal so you won't be tempted by stress-induced grazing that can rack up calories, quickly.
Low blood sugar is often the cause of between-meal cravings, especially for sweets. Eating meals and small snacks that contain lean protein and fiber every few hours helps keep blood sugar levels steady. When sweets cravings strike, try to satisfy them with naturally sweet foods such as fruit (accompany it with a little low-fat yogurt for protein).
A study in the journal Metabolism found that eating half a grapefruit before meals may help reduce visceral fat and lower cholesterol levels. Participants in the 6-week study who ate a Rio Red grapefruit fifteen minutes before each meal saw their waists shrink by up to an inch, and LDL levels drop by 18 points. Though researchers don’t exactly know what makes grapefruit so good at burning fat, they attribute the effects to a combination of phytochemicals and vitamin C found in the tart treat.

Another weight-loss-friendly substitute to keep in mind is favoring salsa over ketchup. While ketchup typically has around 19 calories and 4 grams of sugar per tablespoon, fresh tomato salsa has about 5 calories per tablespoon, no added sugar, and is packed with nutritious veggies. Tomatoes, for example, are loaded with fat-blasting fiber and vitamin C, a deficiency of which has been associated with increased body fat and larger waists. If you can handle spice, toss some jalapenos in your salsa to rev up your metabolism.
