Perhaps you'd like to be the same size you were in high school or when you got married, but that would mean dropping more than 50 pounds. Don't go there — not yet, at least. Set a more realistic goal of losing 5% to 10% of your weight, and give yourself plenty of time and some flexibility to reach that goal, keeping in mind that most people take at least six months to achieve that degree of weight loss.
For example, when it comes to hormones, ghrelin makes you hungry, leptin and other hormones keep you feeling full, Nadolsky says. Thyroid, cortisol, insulin, testosterone, and estrogen all influence how you metabolize and store energy. Meanwhile, genetics have a large influence on both basal metabolic rate (how many calories you burn just to live) and hormone health. While all of these things are impacted by our diet, they’re not only controlled by the way we eat. And, in fact, while sleep, stress management, and, when needed, medication can help regulate other hormone levels such as estrogen and thyroid, our hormones and other physiological processes are often out of our control. And by the way, being able to impact our hormone levels and metabolism with our diet doesn’t always work out in favor of weight loss. As a 2016 review notes, one of the reasons weight loss by way of caloric restriction isn’t efficacious is because “this strategy is countered by the body’s natural physiological response to negative energy balance.” In other words: The body fights back against caloric restriction.

Though it’s hardly realistic to keep people from moving north, there’s evidence to suggest that those living in northern latitudes may need to be a bit more careful about their gut health than the rest of us. A study in the journal Biology Letters found that living in northern latitudes encourages the growth of Firmicutes microbes, which have been linked to weight gain while decreasing the number of microbes linked with slim body types called Bacteroidetes. Generally speaking, the research showed that the number of Firmicutes increases with latitude and the number of Bacteroidetes decreases with latitude. To help ensure a healthy gut no matter where you reside, make sure your diet includes fermented and probiotic-rich foods, both of which encourage the growth of healthy gut bacteria.
Not like you needed another reason to fall in love, snuggle up with your sweetie, kiss or get it on. Harvard Medical School researchers found that all of those things can aid weight loss. How? Lovey-dovey feelings cause levels of the hormone oxytocin to increase, which in turn, decreases appetite. For even more weight loss hacks, check out these 20 Weight Loss Tricks You Haven’t Tried.
Obsessing over the numbers on the scale is not your standard weight-loss advice for women. But new research out of Finland shows that it may be a spot-on suggestion, since the more often dieters weighed themselves in the study, the more weight they lost. In fact, dieters who went more than a week without weighing themselves actually gained weight. These findings, of course, aren't necessarily causal: The less frequent weighers may have been less serious about their diets to begin with. Or maybe they became less dedicated (and less interested in weighing themselves) only after they'd begun to gain weight. Regardless, according to Wansink, co-author of the study: "If you want to be skinny, do what skinny people do." And skinny people, within the context of this study, weighed themselves regularly—anywhere from every day to once a week. A previous study by the same research team found that body weight naturally fluctuates throughout the week and that most people weigh the least on Wednesdays. So if you can't commit to weighing yourself daily, at least hop on the scale every Wednesday. Seeing low numbers will keep you motivated. 

One thing restaurants (and individuals) typically overdo it on when cooking is salt, and that can easily cause unhealthy bloating and weight gain. In fact, one British study found that for every additional 1,000 milligrams of sodium you eat a day, your risk of obesity spikes by 25 percent, so ditch the salt and stick to metabolism-boosting spices such as cayenne and mustard instead.
Enlist a workout buddy. You’re more likely to stick to a weight loss program if you have social support — after all, it’s hard to slack off when someone is counting on you. “Having an exercise partner can help you keep each other on a healthy path,” Heathman says. If you can’t find a workout buddy in your area, join an online accountability group — virtual fit-buddies are fine as long as they’ll nudge you when you need it.

Losing weight seems like a pretty easy concept when you think about it. You eat less, exercise more and the weight is supposed to come off. The fact is, I'll bet you already know how to lose weight. If you're like most of us, you've probably lost weight many, many times...so many times, you're an old pro at it. You may even have your 'go-to' diet or exercise program, powering up your old Weight Watcher's account or starting back to the gym whenever the weight starts to creep up.
You probably know that strength training is important to help you retain your muscles and keep your metabolism up, but cardiovascular exercise – think walking, jogging, cycling or swimming – is important, too. “I see patients who do a lot of strength training, yoga or Pilates, but aren’t doing any cardio," Politi says. "Cardio helps you burn lots of calories, so you create a negative calorie balance that results in weight loss.” She recommends adults strive to get at least 30 minutes of exercise at least five days a week. And in this case, more is better.
Researchers at the University of Minnesota did a series of studies in which they had participants eat vegetables before they put any other food on their plates—and even the researchers were surprised by what they found. "People consumed up to five times more veggies than usual," says Traci Mann, Ph.D., who led the study. And participants who munched carrots before being offered M&Ms subsequently ate one-third less candy than those who were just given the candy first. Why does this trick work? Because when any food is put in front of us, we generally go for it—and the veggies aren't competing with other foods on our plate (which we tend to go for first, if given the option). So start with a salad or crudités.
You can write down what you ate, but when looking back a week later, it may be tough to visualize exactly what a meal looked like. A quicker, and perhaps more telling, alternative is to take photos of each meal. A small study showed that photographic food diaries could alter attitudes and behaviors associated with food choices more than written diaries. Grab a camera and get snapping.
Adding a wide variety of flavorful spices to your foods can help you control portion sizes and lose weight. Research shows that people eat less when their food tastes new and spicy (perhaps because we're forced to pay attention to it?). The crazier the blends of spices, the more novel the food will taste and the more benefits you'll reap, so don't be afraid to mix spices and go out of your comfort zone. Plus, traditional spices like turmeric, cinnamon, and cumin are chock-full of powerful antioxidants.
"When I graduated college in 2012, I was at my highest weight ever. I was embarrassed about my weight and what I looked like, and I was terrified of being the person in the gym who didn't know what they were doing. I sat in my doctor's office and remember deciding that I was going to do whatever it took, however long it took, to change my life. I tried a variety of different diets that worked, but I felt like I was losing my mind not being able to eat certain foods, and I hated that even though I was 'losing weight', I still had a really disordered relationship with food. Food is supposed to bring joy and happiness.
Starting a weight-loss journey can be tough, especially if you're giving up a lot of things you love. Shannon Hagen’s secret to staying positive while losing weight? “I never think of it as giving things up, that makes me feel deprived,” she says. “Instead I focus on adding in one small healthy change at a time, until it becomes a habit.” For instance, instead of being bummed over not having your usual bowl of ice cream before bed, try a new healthy dessert recipe to add to your file.
Nothing beats breakfast in your PJs, but if you put a bit of effort into what you wear prior to chowing down, it could impact your physique. You can keep your goals front and center by dressing up before a meal, Clinical psychologist Katie Rickel tells us in If You Weigh Over 170 Pounds, Here’s What You Need To Do To Lose Weight. Showing that you care about your appearance is a great reminder to eat in a way that reflects that, whether you’re throwing on business attire or a pair of jeans.
Here’s your chance to splurge on those dim, overhead kitchen lights you’ve been waiting. A 2012 study published in the journal Psychological Reports: Human Resources & Marketing found those who ate in environments with soft lighting and music ate fewer calories than those who ate in bright, loud environments. So turn down the lights and turn every meal into a fine-dining experience.

Just as big-box stores can be a psychologically tricky terrain for dieters, so to can healthy-sounding labels on the food that we eat. A Cornell University study printed in the Journal of Marketing Research suggests people eat more of a snack that’s marketed as “low fat.” Participants in the study ate a whopping 28 percent more M&Ms that were labeled “low fat” than when the colorful candies didn’t have the label. As we suggested earlier, avoid being fooled by simply opting for full-fat foods.
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!
Being in optimal ketosis for a prolonged period of time (say, a month) will ensure that you experience the maximal hormonal effect from eating a low-carb diet. If this doesn’t result in noticeable weight loss, you can be certain that too many carbs are NOT part of your weight issue and not the obstacle to your weight loss. There are, in fact, other causes of obesity and being overweight. The next three tips in this series might help you.

Taking this vitamin daily may help you drop pounds. A study at the University of Minnesota found that people who started a weight-loss program with higher levels of D lost more than those who weren't getting enough of the nutrient. Other research suggested that vitamin D appears to boost the effectiveness of leptin, a hormone that signals the brain that you're full. Because it's difficult to get D from food, Shalamar Sibley, MD, an assistant professor of medicine at the university, says you may need to take a vitamin D3 supplement. Many experts now recommend 1,000 international units every day.
Then, assuming you don’t want to lose muscle/strength while you’re in this deficit (or that you’d like to gain some while you’re in this deficit), combine that deficit method with the type of heavy, intelligent, strength-focused weight training needed to ensure this second goal is taken care of, too. (Superior Muscle Growth contains workouts that fit this description.)
If I were to eat 1000 calories/per day (monitored by a doctor) and were to lose my weight quickly. Can I maintain my weight by eating for the new weight that I will be? For example, I am 250 and I want to lose 100 lbs. At 150 lbs I will need about 2045* calories for maintenance. IF I eat 18-1900 calories a day for the rest of my life after the “fad/VLCD” diet, could I keep it off? I am prepared to calorie count for the rest of my life.
Speaking of dressing, you could even take it one step further and buck the suggested choice entirely. While we bet Panera’s Greek salad pairs well with a dressing of the same name, a splash of olive oil and vinegar will also bring out the flavors of the dish and save you a few hundred calories along the way. For a healthy, belly-blasting dressing when you’re eating salad at home, try incorporating some apple cider vinegar or a squeeze of lemon.
For example, a 250-pound person at 5'10" would have a BMI of 35.86. People with BMIs of 25 and above are considered to be overweight. Having a body mass index over 30 places you at risk for developing obesity-related medical conditions such as diabetes, high blood pressure, and coronary artery disease. A BMI over 40 indicates that a person is morbidly obese.
To encourage ketone production, the amount of insulin in your bloodstream must be low. The lower your insulin, the higher your ketone production. And when you have a well-controlled, sufficiently large amount of ketones in your blood, it’s basically proof that your insulin is very low – and therefore, that you’re enjoying the maximum effect of your low-carbohydrate diet. That’s what’s called optimal ketosis.

Even if you’re a sweet tooth, it’s wise to eliminate as much sugar from your diet as you can, especially if you’re trying to keep weight off. “Sugar has been linked to leptin resistance, which is the hormone that tells you when you are full,” explains Dr. Petre. “Bad bacteria also consume sugar and compromise your immune system. [This] causes cell aging and a decline in tissue function and elasticity.” Heart disease, cancer, obesity, and diabetes are just a few additional reasons to avoid it at all costs. She recommends reading food labels closely so that you know just how much sugar you’re really consuming.
Maintenance is hard, but we’ve got good news! You don’t have to do it alone. A study in Annals of Internal Medicine found that low-intensity interventions could help obese outpatients who had just lost 16 pounds hold onto the progress they’d made. For 56 weeks, participants spoke to intervention contacts in group visits at first, then over the telephone with less and less frequency. By the end of the study, they weren’t in contact with anybody at all but still managed to only regain an average of 1.5 pounds. Those who hadn’t had any intervention contacts regained over three times as much weight. So whether you participate in a program or phone a friend, find people who can hold you accountable as you work to maintain your success.
And, save the bread for the end of the meal. Eating simple carbs first dramatically increases blood sugar, which causes your body to pump out insulin and store the calories as fat—the opposite of what you want if you're trying to lose weight, says obesity expert Louis Aronne, M.D., a professor of metabolic research at Weill Cornell Medical College. "Having some vegetables and protein before simple carbs blunts that unhealthy blood sugar response," he adds.
Not long ago, Traci Mann and her colleagues showed study subjects a sad movie, then allowed some of them to eat their favorite feel-better food—such as brownies, cookies and ice cream. Others were given a granola bar, while a third group ate nothing at all. When the researchers assessed their subjects' moods afterward, there was no difference among the three groups. In other words, brownies aren't the surefire pick-me-up we think they are. Mann's takeaway: "When you feel bad, you're far better off calling a friend or going for a walk—both of which are proven to lift mood." These options also have zero calories.
Nuts, the second food to watch, contain a fair amount of carbohydrate, and it’s very easy to unwittingly scarf down large quantities. Cashew nuts are among the worst carb-wise – you’ll find that they contain around 20% carbohydrate by weight. For someone following a strict keto diet with a 20 grams of carbs per day allowance, this means that consuming 100 grams (which happens in a flash!) will have filled their daily quota. Peanuts tend to be around 10-15% carbohydrate – not putting them in the clear either.
A review of more than 600 studies found that being married, and transitioning into marriage, are both associated with weight gain. Transitioning out of a marriage, however, is associated with weight loss. The researchers found that weight gain occurs because of increased opportunities for eating due to shared, regular meals and larger portion sizes, as well as “decreased physical activity and a decline in weight maintenance for the purpose of attracting an intimate partner,” Zero Belly Smoothies states. we’re hardly advocating staying single or getting a divorce (unless you choose to) this research clearly indicates that dieters need to be especially careful around the wedding day. To keep things in check after you take the plunge, meal prep with your partner or develop a workout routine together.
Leaving the comforts of your gym can be difficult, but outdoor workouts have their own unique set of benefits. Research has shown that breaking a sweat outdoors may be more beneficial than burning calories inside. According to a study published in Environmental Science and Technology, exercising in a natural environment outdoors may improve energy levels and decrease stress more than working out indoors can.
The holidays can feel like an extended open bar, but switching to water occasionally can be helpful for your weight-loss strategies—and not just because you’re missing out on a calorie-hit in the moment. That’s because alcohol affects your liver’s ability to process sugar, according to Joshua Scott, M.D., primary care sports medicine physician at Cedars-Sinai Kerlan-Jobe Institute in Los Angeles. It can also lower your ability to burn calories efficiently, he adds, not to mention tanking your inhibitions when it comes to food choices.

“Patients can diet themselves down to any weight they put their minds to, but to maintain that weight, they need to actually enjoy the lifestyle that got them there,” writes Yoni Freedhoff, M.D., the medical director of the Bariatric Medical Institute in Ottawa, Canada, and Arya M. Sharma, M.D., Ph.D., the founder and Scientific Director of the Canadian Obesity Network, in Best Weight, a manual for clinicians who treat patients pursuing weight loss. “A patient’s best weight is therefore whatever weight they achieve while living the healthiest lifestyle they can truly enjoy.”


Having dessert for breakfast seems like a dream come true. You’re not dreaming, though: A 2012 study from Tel Aviv University found eating a big, 600-calorie breakfast that included a dessert — like the three Cs: cookies, cake, and chocolate — lost 40 pounds more than the group that avoided sweets. It might seem backwards, but the researchers said those who had dessert first-thing were able to naturally burn off more of those extra calories throughout the day, and they were also better able to control their cravings later on.
Studies of successful dieters reveal a hard truth: "They remain fairly strict about their eating forever," says James O. Hill, Ph.D., cofounder of the National Weight Control Registry, which keeps data on thousands of people who have lost weight and kept it off. Sound depressing? Think of it this way, suggests Eat to Lose, Eat to Win author Beller: "You just need to find a nutritional strategy you can live with long-term—like allowing yourself to have dessert or a cocktail or two every so often. It's like moving to a new city. For the first year or so it's difficult, but once you establish a routine you get comfortable. You might still miss things about your old life, but you're happy with your new one too."
Cutting carbs altogether can often cause a guilt-ridden binge that will leave you unmotivated and packing on the pounds. Instead of prohibiting yourself from eating the foods you love, set a carb curfew. “For dinner, contestants always have a high-protein, high-fat meal with plenty of fibrous veggies,” Chris Powell of ABC’s reality series Extreme Weight Loss tells us in Chris Powell’s Behind-The-Scenes Extreme Weight Loss Tips. “If they have a post-dinner snack, they stick to protein-rich, high-fat foods like almonds or 2 percent milkfat string cheese.” Nixing carbs at night flips the fat-burning switch by increasing the amount of fat-burning hormones released while we’re asleep, Powell adds.
You probably know that strength training is important to help you retain your muscles and keep your metabolism up, but cardiovascular exercise – think walking, jogging, cycling or swimming – is important, too. “I see patients who do a lot of strength training, yoga or Pilates, but aren’t doing any cardio," Politi says. "Cardio helps you burn lots of calories, so you create a negative calorie balance that results in weight loss.” She recommends adults strive to get at least 30 minutes of exercise at least five days a week. And in this case, more is better.

If you want to do a bunch of unproven, gimmicky, fad-ish, non-evidence-based, non-science-based, sometimes unhealthy, largely-if-not-entirely-unnecessary things with your dietary approach for the purpose of maybe indirectly causing the one proven, non-gimmicky, non-fad-ish, evidence-based, science-based, healthy and necessary thing (a caloric deficit) to happen… then a Group 2 diet is perfect for you.


Trim Portions. If you did nothing else but reduce your portions by 10%-20%, you would lose weight. Most of the portions served both in restaurants and at home are bigger than you need. Pull out the measuring cups to get a handle on your usual portion sizes, and work on paring them down. Get instant portion control by using small bowls, plates, and cups, says Brian Wansink, PhD, author of Mindless Eating. You won't feel deprived because the food will look plentiful on dainty dishware.

Dieters already know to steer clear of sugary cocktails and stick to vodka sodas at happy hour. But nixing booze altogether for a few weeks at a time could really help you jumpstart your weight loss efforts. A Journal of the Academy of Nutrition and Dietetics study found that alcohol causes people to eat an additional 384 calories per day on average, likely because booze makes us more sensitive to food aromas and less likely to resist indulgent fare.
Eating frequently might sound counterintuitive if you’re trying to keep the pounds off, but munching consistently throughout the day is key to blood sugar and hunger management, explains registered dietitian Isabel Smith. When you eat something every three or four hours, it keeps your metabolism humming and you’ll never get too hungry. This ensures you’ll always be in a position to make smart diet decisions which is key to keeping the weight off long term. Not sure what to eat between meals?

There’s a reason Eat This, Not That! hired celebrity trainer Mark Langowski to develop Eat This, Not That! for Abs, our e-book system for getting a six-pack in six weeks: He said it wouldn’t include a single sit-up. “I have been a personal trainer for over 13 years—during this time, I have learned a lot about a lot, but the most important topic that I discovered was 10 years ago when I found out how damaging sit-ups are to the discs in my spine,” he told us. “It was after listening to genius professor Stuart McGill, who is head of spine biomechanics at the University of Waterloo, that I realized I had been doing more harm to myself and my clients by having them do traditional sit-ups.” Instead, “throughout the workout section of the Eat This, Not That! For Abs, I explain how to train the entire body in a way that is activating the core muscles in every exercise you do. A squat may look like a leg exercise
Ah, the über-popular “know your why” strategy. One Brown University study found that when people are motivated to lose weight for appearance and social reasons, they stick with their weight-loss habits for significantly less time than those who are motivated by their health. After all, these external motivators (like looking a certain way or fitting into a cultural ideal) aren’t going to get you going when you’re feeling down, have had a bad day, or are frustrated with a plateau, Albers says.
We probably don’t have to tell you that heavy boozing will pack on the pounds. And you’ve likely heard the phrase “drink in moderation.” The point is, alcohol houses a lot of sneaky calories and has the ability to inhibit healthy eating decisions (midnight pizza delivery, anyone?). Even after you’ve sobered up, alcohol can have negative impacts on strength and may leave you lagging in the weight room days later.

Step far away from the TV — particularly during commercials. All the ads for high-calorie foods and snacks might not seem like they’re doing any harm, but researchers at the Montreal Neurological Institute found that they can activate your brain, making you crave the sweet or fatty foods you see on your screen. And, those signals could end up making you put unhealthy foods on your own plate.
“That first day was so tough, I almost caved and reached for the vending machine at work but I remembered a quote I had on my Facebook page that said ‘The only thing standing between you and your goal is the bullshit story you keep telling yourself as to why you can't achieve it’ and that was enough to make me turn away from the machine,” she says.

Rather than relying on the drive-thru when hunger strikes, prep your meals in advance so that you have healthy grub on hand. “Identity three meals you can prepare with pantry staples and start cooking. Store the meals in your freezer so you always have something healthy on hand when hunger strikes,” Dietitian Christine M. Palumbo, RD, explains in 20 Ways to Lose Weight Forever. “For example, my go-to meals include risotto with frozen shrimp and asparagus, vegetable barley and a red lentil soup. Your goal should be to replace the meals whenever your stash starts running low.”

If you typically wake up early and stay up late, there’s probably something you’re consistently doing throughout that entire time: eating. Your eating window is bigger, so the amount of calories you take in during the day is, too — and that’s why it’s worth keeping that window as small as possible. What’s more, a 2014 study published in the journal Cell Metabolism found that only eating within a 8- to 9-hour window — even without restricting your calories — was an effective way to lose weight and prevent obesity. And for more ways to shed pounds, learn the 20 Science-Backed Ways to Motivate Yourself to Lose Weight.
Diet experts say that we need about one gram of protein per kilogram of body weight to aid muscle growth and weight loss. So if that’s what you’re eating each day, you’re bound to get the body of your dreams, right? Unfortunately, there’s more to it than that. According to University of Texas researchers, the timing at which you consume your protein can make or break how much lean muscle mass you pack on. If you’re like most Americans, you likely consume little to no protein for breakfast, a bit of protein at lunch and the bulk of your daily intake during dinner—which the researchers discovered isn’t ideal for muscle synthesis. Luckily, fitness-minded friends, the fix is a simple one: Just distribute your protein intake evenly throughout the day. The scientists found that those who followed this simple trick had 25 percent higher protein synthesis than those who ate the majority of the nutrient after the sun went down.
