Ultimately, long-term weight loss 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.
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.
Ketosis is the metabolic basis for all “keto” or “ketogenic” diets. On a normal diet that includes carbohydrates (sugar and starchy foods), the body transforms these carbs into glucose, which is used as the body’s main source of energy. But, when we consume a minimum amount of carbs, the body will look elsewhere for that much-needed energy, and that “elsewhere” is fat. In short, when the body goes into ketosis, it is burning fat instead of carbs.
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.
Flexitarian: A mix between the words “flexible” and “vegetarian”, the Flexitarian diet can be described as a vegetarian going on a short carnivore vacation. It is a mostly vegetarian diet that sometimes incorporates meat, fish, and poultry, and it is ideal for people who want to benefit from vegetarianism but cannot resist the temptation of animal products.  Also, a recent study suggests that, by going meatless from time to time, you may actually help in the fight against climate change. 
"People should pick activities they enjoy and that fit into their lifestyle in order to increase their chances of sticking with it to lose the last 10 pounds. For those who have hit a weight-loss plateau and can't seem to lose that weight, you'll need to mix things up in order to see results. Tabata-style training, HIIT classes and resistance training can all be effective weight-loss modalities for the right person." — Timothy Lyman, ACE certified personal trainer and Director of Training Programs at Fleet Feet Pittsburgh
"While losing weight for effective long-term benefits takes time, there are a few quick ways to help shed 10 lbs in a month or so. It requires getting into a routine you know you'll stick with, making small nutritional changes so that you can stick with a plan, and having a bit of patience before you notice changes. It takes 4 weeks for you to see changes in your own body, and sometimes up to 8 weeks for others to notice!" — Nicole Houvig, AFPA Certified Personal Trainer with the Rockay expert team

U.S. News evaluated and ranked the 41 diets below with input from a panel of health experts. To be top-rated, a diet had to be relatively easy to follow, nutritious, safe, effective for weight loss and protective against diabetes and heart disease. The Mediterranean diet took the top spot, while the government-endorsed DASH diet, which stands for Dietary Approaches to Stop Hypertension, came in second.
"Oolong, or 'black dragon,' is a kind of Chinese tea that's packed with catechins, nutrients that help promote weight loss by boosting your body's ability to metabolize fat. A study in the Chinese Journal of Integrative Medicine found that participants who regularly sipped oolong tea lost a pound a week, without doing anything else to change their diet or exercise habits." — Kelly Choi, author of The 7-Day Flat-Belly Tea Cleanse
The power of emotional eating should never be underestimated, as it is a strong factor in determining whether or not you'll be successful on a diet. When you eat less than you should, you inevitably get hungry, after which you might feel angry, and once this happens the “hangry” stage sets in and you’ll feel more inclined to skip the diet altogether or go on a food binge. For this reason, most successful diet plans prioritize satiety or the feeling of “fullness.” 
The plan promotes long-lasting, sustainable changes, and undoubtedly a bounty of research backs this up. In fact, one December 2013 study in the American Journal of Medicine shows that people following Weight Watchers were close to nine times more likely to lose 10 percent of their body weight, compared to people following a self-help diet plan. (20)
A relatively new offering, the Nutritarian diet is based on maximizing the amount of healthy vitamins, minerals, and trace nutrients in your food, balancing your hormones, and avoiding toxins. The plan—created by Joel Fuhrman, M.D., author of The End of Dieting—is nutrient-dense, plant-rich, and includes anti-cancer superfoods to help you not just lose weight but live a long, disease-free life. (P.S. Follow these guidelines to make sure you're absorbing all the nutrients from your food.)
All bodies are not created equal, and this is why there is no one “magical” diet solution for all. What’s more, even when two people with similar body compositions try the same diet plan, the difference in results can be overwhelming. “Bodies react differently depending on their genetic makeup and metabolism rates,” said Barcelona-based and Certified Nutritionist Carla de la Torre, and added, “this is why, for example, some people can get abs on a bread and cookies diet, while others cannot get the desired 'six pack' even after undergoing rigorous eating and exercise regimes.” 
"One of the keys to long-term and sustainable weight loss is to cut total calorie intake, and there's no better way to do that than by eating just a little bit less of what you currently eat. Once you get into a habit of reducing portions—especially of sugary, fatty and other nutrient-poor foods—you can fine tune your diet to incorporate more nutrient-rich foods. But paring portions is still the best first step [in an effort to lose 10 pounds]." — Elisa Zied, MS, RDN, CDN, author of Younger Next Week

Why couldn’t we review for taste? Due to freshness and food safety concerns, the three meal-delivery companies that made our cut (South Beach Diet, Diet-to-Go, and Nutrisystem) only ship inside the continental US, meaning delivery is not available to Alaska, Hawaii, and other US territories. ConsumersAdvocate is headquartered in Dorado, Puerto Rico, which made it virtually impossible for our team to actually try the food prepared by the diet companies being reviewed. To make up for this obstacle, we read hundreds of customer and expert reviews regarding the taste of the food prepared by the companies that made our “best” list. We will continue trying to get the food delivered to our offices; if and when that happens, we will review the meals for taste and upgrade this article accordingly.

Because the diet isn’t as restrictive as a traditional vegan or vegetarian diet, it may be simpler to stick with — hence its No. 2 ranking in U.S. News & World Report’s Easiest Diets to Follow category. Because you’ll be eating meat some of the time, you may also be at a lower risk of the aforementioned nutrient deficiencies that vegetarians and vegans may face.
If you don’t have an established exercise routine, “walking is a pretty good entry point for people,” says Gagliardi. One small study published in The Journal of Exercise Nutrition & Biochemistry found that obese women who did a walking program for 50-70 minutes three days per week for 12 weeks significantly slashed their visceral fat compared to a sedentary control group.
A 2015 study from the Annals of Internal Medicine showed that for those who have a hard time following a strict diet, simplifying the weight loss approach by just increasing fiber intake can still lead to weight loss. Women should aim for at least 25 grams of fiber per day (based on a 2,000-calorie) diet, according to the most recent U.S. Dietary Guidelines. Start with our high-fiber diet plan.
Research also finds that drinking frequently—even if it’s a moderate amount—can set you up for excess pudge. Not only do the beverages themselves contain unnecessary calories, but once you start sipping too much, your inhibition also plummets, according to one 2016 study. The result? You’ll have a hard time resisting that late-night slice of pizza. So if you're going to imbibe, be sure to stick to one drink per day for women and up to two drinks for men.

The most basic approach to weight loss is burning more calories than you consume. For instance, since 3,500 calories equals 1 pound of fat, a weight loss app—or even just a pen and paper—can help you decide how many calories you need to cut from your diet or burn at the gym in order to meet your goals. “If you were to burn 500 more calories per day 7 days a week, that would lead to 3,500 calories in a week and 1 pound of weight loss,” says Gagliardi.

“This is a great way of eating that I highly recommend to many clients, and I even model in my own life,” says Elizabeth Shaw, RDN, who is in private practice in San Diego and is the co-author of Fertility Foods Cookbook. “Since the premise of the diet is designed to help people who have high blood pressure, low-sodium foods are recommended. But considering that most Americans exceed their daily sodium levels anyway, it’s not surprising that dietitians recommend this style of eating for treating many different conditions, such as heart disease and obesity.”
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.
"To lose weight you should primarily eat whole foods, but don't eliminate your favorites. Consistently eating nutrient-dense food on a day-to-day basis will improve the chances of upregulating metabolism and of eliminating nutritional deficiencies. That may mean tracking what you eat in some way at first, but it doesn't mean ruling out entire food groups or foods you love. Consistent quality nutrition while learning to enjoy treats in moderation will set you up for long-term sustainable success. — Victoria Viola, PN Certified Nutrition Coach, NSCA CPT, Co-Founder, Excelerate Wellness, LLC

The idea is that the fasting induces mild stress to the cells in your body, helping them become better at coping with such stress and possibly helping your body grow stronger. The verdict is still out regarding the diet’s long-term effectiveness with weight loss, according to a review of preliminary animal research published in January 2017 in Behavioral Sciences. (17)
All meals are important, but breakfast is what helps you start your day on the right track. The best, heartiest breakfasts are ones that will fill you up, keep you satisfied, and stave off cravings later in the day. Aim to eat anywhere between 400 and 500 calories for your morning meal, and make sure you're including a source of lean protein plus filling fat (e.g., eggs, unsweetened Greek yogurt, nuts, or nut butters) and fiber (veggies, fruit, or 100% whole grains). Starting your day with a blood sugar-stabilizing blend of nutrients will help you slim down without sacrifice.

"When clients come to me, many of them have been through the diet wringer. They've tried every fad and gimmick and, of course, they've failed to maintain long-term success. The key to losing 10 pounds and weight loss, in general, is to never feel like you're on a diet, because diets don't work. If you feel deprived, you will never make it past a few weeks. The only way to achieve long-term weight loss is to learn to appreciate food as fuel and slowly replaced processed food that cannot properly energize the body with real food that can. After a while this will become second nature and won't feel like a daily struggle." — Laura Burak, MS, RD, CDN
Each one of us has a different preference for food. Some like chocolate, some like french fries and so on. But the desire to have junk is common to all of us. What’s your preference for junk food? Is it chocolate? Is it sweets? Find your poison and make sure you don’t have easy access to it. Don’t stuff your fridge with junk food. ‘Watch what you eat and don’t binge!’, says Neha Dhupia. 

Right now, 2 out of 3 Americans are overweight or obese, and the number keeps skyrocketing year after year. Some experts consider obesity an epidemic more dangerous than that of opioids due to its role in the rise of life-threatening conditions such as diabetes, stroke, certain cancers, asthma, and osteoarthritis. Obesity is responsible for 18% of deaths among Americans over 40 years old, and 1 in 5 children in the US suffers from obesity. The medical costs for obesity-related treatments have now reached an exorbitant $150 billion per year.

When you drink liquid carbs, like the sugar in soda, your body doesn't register them the same way as, say, a piece of bread, according to a review of studies published in Current Opinion in Clinical Nutrition & Metabolic Care. That means, even though you're taking in calories, your fullness cues aren't likely to signal that you're satisfied once you finish off a can. And that can lead to consuming more overall.
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.
