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.
While 1,200 may be the right number for some people, it can be super restrictive for others, says Jaclyn London, MS, RD, CDN, Nutrition Director at the Good Housekeeping Institute. That’s why we’re using 1,200 as our base, and encourage you to build upon these meal and snack ideas by doubling (or tripling, quadrupling …you get the point!) up on veggies at any opportunity — and adding more fruit at snack time, too. You can also add 1-5 ounces of protein at all meals if at any point you’re feeling like it’s just not enough food to keep you satisfied. The combo of fiber from produce and lean protein makes this an adaptable strategy that’ll help you lose weight safely — one meal (and snack) at a time!
"Research continues to support the role of a high-protein diet and weight loss, however, we don't want to reach those protein needs exclusively with animal proteins. Plant proteins found in beans not only help us feel full and stabilize blood sugar but beans are associated with longevity. Who cares about being skinny if you die young?" —Jennifer McDaniel, MS, RDN, CSSD, LD, food and nutrition expert
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.

By allowing a daily intake of 1,200 to 1,600 calories, broken into a ratio of 50% carbs, 25% protein, and 25% fat (except for the low-carb plan), Diet-to-Go’s portions achieve a caloric middle ground that provides you with energy and the feeling of fullness while still being low enough to allow for slow-but-steady weight loss. In short, you’ll shed 1 to 3 pounds per week without feeling “hangry” all the time.

"Don't skip breakfast—it really is the most important meal of the day. Eat breakfast within 90 minutes of waking, and then have something healthy to eat every three to four hours after that. When we skip breakfast or wait too long to eat in the morning, our bodies start to conserve energy and our metabolism slows down. Skipping breakfast also leads to overeating throughout the day." — Ilyse Schapiro, MS, RD, CDN, author of Should I Scoop Out My Bagel?


If you like eating meat and want to lose weight, you might be tempted to try this recent extreme diet fad that proponents have made some pretty outrageous claims about. One: that eating nothing but meat can cure you of autoimmune diseases. The problem is that there’s no good research to support that notion, or any other health claim, for that matter. Indeed, omitting foods known to be good for you — fruits and veggies among them — can lead to a bunch of unwanted side effects, including constipation and potentially dangerous nutrient deficiencies. Still, since you’re cutting out so many food groups, there’s a decent chance you’ll lose weight, experts say. Regardless of any possible benefits you might see, this restrictive approach is definitely one you’ll want to ask your doc about before you even consider diving in.
The researchers hypothesize that participants who abstained from animal products dropped significantly more pounds since plant-based foods include loads of filling fiber and slow-to-digest complex carbs. Though more research is needed to confirm these results, the study authors write, "Vegetarian diets appeared to have significant benefits on weight reduction compared to non-vegetarian diets."
The easier it is to seamlessly fit a diet plan into your life without major lifestyle changes, the better. After all, by focusing on holistic long-term results rather than trendy short-term solutions, sustainability becomes the number one enemy of the feared “yo-yo” effect. During our investigative process, we asked ourselves: What makes a diet plan sustainable? After long hours of research, we decided that the following factors can determine a plan’s sustainability, and thus its odds of success: 
In a nutshell, a “fad” is a diet trend that is most likely temporary, boosted by marketing dollars, and not scientifically-tested for safety and/or effectiveness (and sometimes outright dangerous). Before committing to any diet plan, make sure to do some research regarding your chosen plan’s claims, so you can be certain it is not only nutritionally sound, but also the perfect one for you.

If you want to lose fat, you have to eat fat...the right kind, that is. Adding healthy fats, in the form of monounsaturated and polyunsaturated fats, can help you feel more satisfied with your meals. Yasi Ansari, MS, RD, CSSD, national medial spokesperson for the Academy of Nutrition and Dietetics, says, "Fat sources that I recommend boosting in the diet come from unsaturated fatty acids found in foods like olive oil, nuts, avocados, fatty fish, and eggs, as they can help increase satiety while providing a variety of health benefits when consumed in moderation." You can increase your intake of healthy fats by adding some chopped avocado into your salads, enjoying wild salmon twice a week, and having a little peanut butter with your post-workout snack or smoothie. Just remember to enjoy them in moderation as they're still very calorie-dense, Ansari says.
“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.” 

Even though theoretically anyone can benefit from a healthy diet, it’s recommended that you consult with your doctor before beginning a new diet plan. Also, there are people for whom certain plans may not be ideal, including people with diabetes, pregnant women, people allergic to certain foods, people with hypertension, and people with a history of eating disorders.
"How easy it is for someone to lose 10 pounds depends on a lot of things: age, gender, activity level, basal metabolic rate, and how much weight he or she has to lose" explains Kate Huether, MD, of The ReKovery MD, who also holds a master's degree in nutrition. "If someone is very overweight it is easier to lose excess weight as opposed to someone who is thinner," Dr. Huether adds.
Very few diet plans outlive temporary fads and trends, and WW is definitely one of them. The diet company formerly known as Weight Watchers has kept up with the times by reinventing and rebranding itself as WW, which stands for “Weight Loss & Wellness.”  While the company’s diet approach is still based on the Smart Points food-tracking system, it has recently incorporated meditations, audio workouts, food logging, Zero-Point foods, a redesigned app, and online support for a more holistic approach to dieting.
"Burpees are such a great way to activate multiple muscles, get the heart rate up and burn mega calories. In one single burpee, you work your legs, arms and abs and you also elevate the heart rate to increase cardiopulmonary strength. If you're looking to lose weight, incorporating them into your workout routine is a must."—Kit Rich, celebrity trainer and co-owner of SHIFT by Dana Perri
For years, the Smart Points system has been the backbone of WW’s dieting strategy. It assigns value (points) to foods based on calories, saturated fat, sugar, and protein. The higher the number, the less you should be eating that specific food. After enrolling in one of WW’s plans, you’ll be given your personalized diet program, with a certain number of Smart Points (called your “budget”) to allocate however you want during the day. Daily points allow for three meals per day, two daily snacks, and a certain amount of free points. If you don't eat all the points, there are rules regarding “rollover” points.
Rather than rely entirely on the information provided by the companies to determine weight management effectiveness, we spent weeks browsing through hundreds of unpaid customer testimonies (not endorsed by any company) to get a feeling on the accuracy of the claims they make. In fact, these testimonials provided us with a much more truthful and in-depth insight regarding how effective diet plans really are. 
The Dietary Approach to Stop Hypertension, like the TLC described earlier, is endorsed by the National Heart, Lung, and Blood Association, the American Heart Association, and the 2015 Dietary Guide for Americans. It was developed with the purpose of helping people reduce blood pressure, prioritize the consumption of calcium, potassium, and magnesium, and, most importantly, abstain from sodium.

There’s a large spectrum of where people can fall on a vegetarian diet: For example, vegans consume no animal products, whereas ovo-lacto vegetarians eat both dairy and eggs. The eating style may help with weight loss, suggests a review published in August 2017 in Nutrients, but some vegans and vegetarians may become deficient in specific nutrients, such as calcium, iron, zinc, and vitamin B12, according to an article published in December 2017 in Nutrition, Metabolism and Cardiovascular Diseases.

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.
With its pre-packaged meals, portion-controlled menus, and strict caloric restrictions, the Nutrisystem meal delivery plan is ideal for people looking to lose weight fast without having to do any complicated meal planning. The company claims its 28-day program can help you lose up to 13 pounds by eating healthier versions of the foods you already love.
"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

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.

If you’ve been eating fast food for years, get real about your approach: You’re probably not going to stick to an organic, gluten-free, paleo overhaul for very long. "You want to change as little as possible to create calorie deficit," says Dr. Seltzer, who insists the best way to support sustainable weight loss is to incorporate small changes into existing habits. So instead of giving up your daily BLT bagels in favor of an egg-white wrap, try ordering your sandwich on a lighter English muffin. Or say you eat a snack bar every afternoon: Swap your 300-calorie bar for a 150-calorie alternative. "Your brain will feel the same way about it, so you won’t feel deprived," he says.
Once you download the app on your phone, free of charge, you’ll be asked to submit your age, weight, and weight goals, as well as information regarding your motivations, triggers, lifestyle, eating habits, and health issues. The app then uses its database to create your personalized, comprehensive diet plan and get you in touch with your goal specialist, your personal coach, and your support group.
After a free diet analysis based on your Body Mass Index and submitting your ideal weight, Nutrisystem will recommend a plan to help you reach your goal. This plan is designed by nutritionists and allows for six meals a day (4 of them delivered by Nutrisystem and 2 to be prepared by you, following Nutrisystem’s guidance and recipes). This way you won’t be hungry for long, making it easier to stick to the diet plan until its completion.

The one thing that is sure to make you lose weight is this simple equation: CICO, short for “Calories In, Calories Out.” In short, it means: a) if you eat more calories than your body spends, you’ll gain weight; b) if you eat less calories than you spend, you’ll lose weight. In spite of all their differences, all diet plans that aim to help you lose weight must adhere to this seemingly simple equation. However, most experts agree that, by itself, CICO is an incomplete and flawed approach due mainly to its focus on quantity over quality, and the fact that it doesn't take nutrients into account.


Safety: The history of dieting is filled with dangerous and downright life-threatening practices, from the fad of ingesting cotton balls to the infamous tapeworm diet. That's why, when looking for the best diet plan, nutritional balance and reduced caloric intake (usually 1,200 for women and 1,500 for men) are a must. After all, a diet is supposed to make you healthier, not make you sick.
“There are many diet plans on the market today that promote good health,” says Emily Kyle, RDN, who is in private practice in Rochester, New York. “The key is finding one that does not cause you stress or agony.” Ask yourself questions such as: Would the diet guidelines make you happy? Anxious? Stressed? Are you able to follow them long term? “Factors such as enjoyment, flexibility, and longevity should be strongly considered,” adds Kyle.
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.
One of our most popular salad recipes, Spinach-Strawberry Salad with Feta & Walnuts (see Associated Recipes), gets a makeover in these simple yet totally satisfying meal-prep spinach salad bowls. They require minimal prep and can be customized to your taste. Swap in roasted salmon for the chicken thighs, and almonds or pecans for the walnuts, and use any fresh berry that looks good at your market.
When it comes to the "best" diet for most people, this one consistently ranks at the top of every list. If you can't afford a cruise to the Mediterranean (yet!), at least you can eat like the beautiful, long-living, and famously healthy people from the region. The Mediterranean diet teaches you to eat like a Sardinian, one of the "blue zones" identified by researchers as having a high number of people living past 100—by eating more fish, olive oil, healthy fats, and fresh vegetables. The point is to have not just a longer life but also a healthier and happier one, whether you're trying to lose weight or not. (Really—research shows that you can reap the benefits of the Mediterranean diet without cutting calories.)
To lose 10 pounds fast, Jackson explains you'll then want to cut your calorie consumption by 10%. "For example, if you average 2,000 per week, reduce that amount to 1,800 calories and see if you lose weight. You'll also want to take notice of the percentage breakdown of protein, carbs and fat. Aim for a 'bodybuilder breakdown' which is 40% protein, 40% carbs and 20% fat. You'll begin to drop weight in no time!"
