From celebrity-endorsed to science-backed, finding the best diet for your body and lifestyle can be an exercise in frustration—definitely not the kind of exercise you need right now! To make your search easier, we've pulled together the 10 most popular diets based on which ones have consistently ranked highest on the annual U.S. News & World Report rankings, WebMD, and other current diet lists. Just know this: It's not about finding out which diet is the most popular overall but which one fits your goals and lifestyle the best. After all, the best diet for you is the one you can stick with (and enjoy)!
A similar program, TOPS (Est. $32 per year, plus $5 chapter dues), pairs a wealth of educational material with group meetings in your community, also called "chapters." TOPS, which stands for Take Off Pounds Sensibly, uses The Food Exchange System, which users say is easy to understand and follow. It has categories of foods with similar serving sizes and caloric loads, and it's easy to swap one food for another. You can even purchase exchange cards that give you food options within categories at a glance, as well as a variety of other accessories, such as food prep tools scaled to accurate portion sizes.
Many diet plans cut out entire food groups, which can create nutrient deficiencies as well as health problems. For instance, if the diet is very low in carbohydrates and you have type 1 diabetes or type 2 diabetes, it’s probably not a good fit. And if it’s too restrictive and you’re pregnant or breastfeeding, it’s not a good idea, either. Keep in mind that pregnancy is not a time for weight loss. Speak with your doctor before making any changes to your diet if you are pregnant or breast-feeding.
Although you do want to increase your walking over time, this doesn’t necessarily mean that you have to be working your way up to a more intensive form of cardio like swimming or running. “Moving on to new exercises is not something someone should feel they have to do unless their goals change and a new exercise is needed to support those goals,” says Gagliardi. “Walking alone can be progressed by changing the distance, speed, terrain, and by adding intervals.”

Over the last three months I’ve lost 22 pounds simply by upping my exercise and reducing bad calories. I’m 68 years old, always in good shape, but added sedentary pounds as I aged. (6 feet tall, 212 pounds before — 190 pounds now) I’ve generally restricted my diet to about 1200 calories a day — 200 – 300 for breakfast, 200 for lunch, and about 700 or less for the rest of the day. I try to vary the foods, do as much exercise as I can (biking, swimming, walking, weights). I drink as much non-caloric liquid as I can and I try to find food that fills me up — vegetables, fruits, mostly. I eat some cheese and a good hamburger occasionally, although I avoid most meat. I still work full time. I realize the discipline necessary, but it’s not that hard to do. I rely on a good scale and moderate my diet each day to keep a constant weight. My blood pressure has dropped from 130/80 to 117/72 and heart rate is resting 58. I’m lucky that my chronic diseases are not yet serious (osteoarthritis and borderline cholesterol, although I dont take statins because of reactions). I’m not a diet fadder, but using common sense goes a long way. Eat smart and work out. MM
WeightWatchers is one of the best known weight loss programs around. The reason it’s successful is that it’s often viewed as one of the easier programs to follow, helping you to change the way you think about and behave around food. Nothing is off limits, so you can still enjoy your favorite meals and snacks, even a drink of alcohol now and then, meaning...

“A lot of people think the foundation of a paleo diet is high-fat meat, but I suggest that it’s vegetables,” says Hultin. The concept is to eat only foods — including meat, fish, poultry, eggs, fruits, and vegetables — that would have been available to our Paleolithic ancestors. This means grains, dairy, legumes, added sugar, and salt are all no-no’s.
There is plenty that you can do to get even more out of your walks. Stephanie Cyr began her 102-pound weight loss journey by walking for an hour each night—but there was a catch. "I mapped out a 3-mile course that took me through the hills in my neighborhood," she says. Live in a flat area? Alternate 1 minute of super-fast walking with 1 minute of slower walking for a calorie-torching interval routine.

The upshot of all these chemicals floating around is big trouble for big-bellied guys. In a study at the University of Alabama at Birmingham, researchers took 137 men of all ages and sizes and used seven different measurements to determine their risks of cardiovascular disease. The single best sign of multiple heart-disease risks? No, it wasn't the guys' family histories or their cholesterol profiles. It was the amount of abdominal fat they carried.
And that raises the most important point: Thinking about exercise as a way to work off food or simply allow you to eat sets up a host of unhealthy and unhelpful thought patterns and habits around food and exercise. For instance, one 2013 research review found that, not only did people generally overestimate how many calories exercise burned—when they did work out, they ramped up their food intake. And if you overeat following exercise, any caloric deficit created during your workout can become a wash. And related: thinking of food as a reward and exercise as a punishment is likely to sabotage your weight loss efforts anyway.
Remember that in order to keep the pounds off and maintain your happy weight, you need to develop a healthy lifestyle. That means forming a routine and keeping up the habits so you can hang on to them for life. "I forced myself out of bed at 5:30 a.m. four to five times a week to run," says Erin Bowman who has kept off 69 pounds. "My first few were horrible. But I stuck with it, eventually trading my run-walk intervals for steady 45-minute jogs," she says.
The final possible culprit behind stubborn weight issues may be the stress hormone, cortisol. Too much cortisol will increase hunger levels, bringing along subsequent weight gain. The most common cause of elevated cortisol is chronic stress and lack of sleep (see tip #10), or cortisone medication (tip #9). It’s a good idea to try your best to do something about this.
Since we can’t spot reduce fat, the only way to ever get those flat abs is to burn body fat overall. For this reason, HIIT workouts, exercises that work multiple muscle groups simultaneously (like push ups, squat thrusters etc.), and weight lifting are going to be the most effective fitness strategies for bringing out your six pack because they are the most metabolic. Hours of cardio and tons of crunches are not the way forward here.
And some of these factors can go pretty deep. Albers says that people often don’t realize how dramatically past experiences influence our relationships with ourselves and bodies. For example, having to clean your plate as a child, getting sweet treats to “cheer up” after a bad day at school, or being called “fat” when you were 8 years old all likely have an impact. “Comments about your body or being urged to lose weight by a parent can do emotional damage for the rest of your life,” Albers says. Unless you deal with these issues, “many people spin their wheels and don't know why they feel so stuck,” she says. For this reason, Langer often refers clients to psychologists who specialize in food issues, and she won’t work with those clients on the nutrition side of things until they’ve started to unpack these fundamental emotional factors. Understanding your relationship to food is an important step in trying to change it.
Fiber works its weight loss magic in multiple ways. It helps you feel fuller, longer so eating fiber-rich foods is the dieting equivalent of working smarter, not harder. Plus, fiber takes a long time to digest, so fiber-rich foods don’t cause spikes in blood sugar that can send your insulin levels soaring. On the other hand, when you eat the so-called bad carbs (the refined or sugary ones that lack fiber), you may wind up with an insulin response that promotes fat storage. The takeaway: More fiber equals less fat storage.
Instead of satisfying your sweet tooth with some refined sugar, turn to berries and enjoy a slimmer waistline in no time. Berries are loaded with antioxidants, which can help reduce inflammation throughout the body, and research from the University of Michigan reveals that rats given a berry-rich diet shaved off a significant proportion of their belly fat when compared to a control group. Berries like strawberries, raspberries, blueberries, and blackberries are also loaded with resveratrol, an antioxidant pigment that has been linked to reductions in belly fat and a reduced risk of dementia, to boot.
I love this study because it examined a realistic lifestyle change rather than just a fad diet. Both groups, after all, were labeled as healthy diets, and they were, because study investigators encouraged eating high-quality, nutritious whole foods, unlimited vegetables, and avoiding flours, sugars, bad fats, and processed foods. Everyone was encouraged to be physically active at a level most Americans are not. And — this is a big one — everyone had access to basic behavioral counseling aimed at reducing emotional eating.
Insulin (in-suh-lin): A hormone made by the cells in your pancreas. Insulin helps your body store the glucose (sugar) from your meals. If you have diabetes and your pancreas is unable to make enough of this hormone, you may be prescribed medicines to help your liver make more or make your muscles more sensitive to the available insulin. If these medicines are not enough, you may be prescribed insulin shots.
Schedule a workout with a friend—you'll be less likely to skip out on it knowing that she is expecting you to show up. Or, use your workouts as "dates" where you can catch up with friends. "Every Wednesday, I take a Zumba class with the friends I met at Weight Watchers," says Michele August, who lost 117 pounds. "It's our weekly girls' night. We catch up, bond, and even enjoy a fun workout that burns a bunch of calories!" 
Of course, you want to get to the bottom of why you’re not feeling so hot. One study found that practicing relaxation techniques helped obese women who were emotional eaters lose weight over the course of three months, along with helping them reduce depression and anxiety. (7) Engaging in other activities that can help you relax are a better option than emotional eating.
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.)

Making a smoothie and ordering a smoothie at a shop are two very different things. When you make a smoothie yourself, you can measure the exact amount of fruit, swap water or almond milk for juice, and avoid any additional sweeteners. But many pre-made smoothies contain between 600 to 1,000 calories, on average, and are loaded with sugar. “An average height woman who is trying to lose weight is probably on a 1,200 to 1,400 calorie diet,” Amidor says. “So consuming one smoothie with 1,000 calories can easily sabotage any weight loss efforts.”
No weight loss program rivals Weight Watchers' (Est. $20 and up per month) record of scientifically proven efficacy and enthusiastic expert and dieter endorsements. Its combination of in-person and/or online support and motivation, flexible points-based meal planning, and physical activity are hard to beat. There are no off-limit foods, and the program can be customized for any dietary need, making it a good choice for vegetarians, vegans and anyone who has a specific food allergy or intolerance. It emphasizes fresh fruits and vegetables by making them "free" foods -- in other words, foods that don't have to be portioned or tracked.
The good news is that if you're struggling with your size, reducing your calorie intake and increasing your activity level have been clinically shown to help you lose weight. The bad news is that there are no shortcuts and no short-term fixes. Fad diets, herbal supplements, "fat-burning" pills, and highly restrictive diets don't work for long, if at all, and some may cause more harm than good.
“Diet and exercise are a marriage that should never divorce,” said Giancoli, noting that the benefits of exercise aren’t restricted to the sheer number of calories you burn during thirty minutes on a treadmill. (Need one of those, by the way? We have some favorites.) Instead, research shows that muscle tissue burns more calories than fat tissue, proving that “muscle mass is a key factor in weight loss.”
It's no surprise that Dr. Dean Ornish's program is such a powerful tool for weight loss, considering its easy adaptability as a lasting lifestyle. The diet is mostly plant-based, keeps sodium intake in moderation, and limits coffee to a cup a day (two cups decaf) — so if you're looking to lose weight while keeping your java flow, you may want to consider another plan.
But the information that researchers are unearthing about the differences in the way that men and women lose weight inspires hope that the next generation of weight-loss advice will be more tailored and effective than the generic tips that have gotten Americans no closer to sliding into their dream jeans. (More than a quarter of Americans are obese, according to a May Gallup poll, a number that has been ticking upward for years). Although experts have long insisted that losing weight is simply a matter of burning more calories than you consume, they now say that it’s much more complicated than that.

The lowest ranking diets were the Keto Diet and the Dukan Diet, which tied for last place. People who follow the Keto Diet slash carbs and fill up on fats in order to help the body enter of state of “ketosis,” where the body breaks down fat. The Dukan Diet is a rule-heavy plan that goes in stages, including a phase of eating a lot of protein. The experts rated both diets as hard to follow
Including your significant other in your workouts can help to keep you on track, even if your goals aren't necessarily the same. "My hubby and I make exercise outings 'our' time," says Twyla Grimes, who knocked off 26 pounds by combining an hour on the stairmill or treadmill with strength training. "We'll go to the gym for an hour and lift weights together. Having him there keeps me accountable."
Fiber is a type of carbohydrate that your body can't digest, and it helps regulate the body's use of sugar as it slowly passes through your digestive system. Increasing your daily fiber intake can result in greater satisfaction after meals, less blood-sugar spiking and crashing, and subsequent reductions in the amount of calories eaten for the rest of the day. When trying to trim belly fat, aim to get at least 25 grams of fiber in your diet each day. Foods that are rich in fiber include pulses, like lentils and beans; apples and pears, with the skin; nuts and seeds; and cruciferous vegetables like broccoli and Brussels sprouts. Try this recipe for Tabbouleh with Chickpeas for a fiber-packed side dish or a one-dish dinner!
Barley got its hunger-fighting reputation after Swedish researchers found that eating barley or rye kernels for breakfast kept blood sugar on an even keel. That's because the carbs in barley and rye kernels are "low glycemic index," meaning they raise blood sugar more slowly than some other carbohydrate foods. This helps you avoid a spike, and then a drop, in blood sugar, which can leave you feeling famished.
A diet plan is one step towards achieving a healthy lifestyle. Fitness and health guidelines give information on how exercise and living an active lifestyle could complement the benefits of eating healthy. Be sure to check important guides such as eating out, lifestyle tips, portion control guides, clinical research and exercise tips to achieve the maximum benefits of enrolling in a diet program.
Drink water. Contrary to another popular misconception there is no specific amount of water you should ingest. Everyone has different needs based on genetics, activity level, the environment they live in etc. The key is to drink water until your pee looks like lemonade. If it looks like apple juice keep drinking. The reason this helps flatten your tummy is two fold: hydration can boost fat metabolism by up to 3% and drinking water flushes out excess bloat and water weight you might be holding on to.
Also some research shows that the human body is primed to consume most of its calories during daylight hours. But the lifestyle is problematic for many: Because family meals and dinners with friends often are scheduled for after sunset, "people who try to stop eating after 7pm can’t do it every day for the rest of their lives," says Dr. Seltzer, who supports an alternative strategy: Eating a hearty meal at your regular dinnertime.
The plan is simple: Commit to two weeks of restricted dieting, then transfer to a sustainable regime. Phase one: Cut out restaurant food, added sugar, eating while watching TV, snacking on anything other than fruits and veggies, and limit meat and dairy. You’re also asked to add four healthy habits, simple tweaks like having a good breakfast every morning.
But I've seen some women beat themselves up over a few extra pounds, even though this does little more than destroy their self-worth. Berating yourself will not help motivate you to control your weight and improve your health. So the next time those negative thoughts creep into your head, recognize them for what they are and replace them with positive ones.

Or skip your favorite early-morning show—whatever it takes to grab a few more minutes of sleep each day. When researchers at the University of Chicago studied men who were sleep-deprived, they found that after just a few days, their bodies had a much harder time processing glucose in the blood—a problem common in overweight diabetics. When the individuals returned to a more normal seven to eight hours of sleep a night, however, their metabolisms returned to normal.
Replace the negative voice in your head that's telling you to quit with a motivational saying that will inspire you to keep going even when it gets tough. "I powered through workouts telling myself, 'I can do hard things!'" says Megen Karlinsey, who kept off 150 pounds. Her mantra helped her accomplish a triathlon, which she signed up for to blast a weight loss plateau.

It's not just what you eat that can make you pack on pounds—it's also how much. Before dropping 102 pounds, DeGennaro did not have a grip on proper serving sizes. "Sitting down to dinner with my husband and three kids, I'd scarf down mounds of pasta and endless rolls," she says. "Adjusting to smaller portions was tricky at first; I'd round out meals with extra veggies to keep from getting hungry."

Nuts have a very high satiety power—meaning they make you feel fuller after eating than many other foods. And even though they’re high in calories, those calories appear to be processed differently in the body. University of Michigan researchers found that men who added 500 calories’ worth of peanuts a day to their diet gained no excess weight at all.


That’s because strength training helps you build muscle, which will replace body fat. In fact, strength training is one of the few activities you can do to spike the amount of calories you burn, even after you’re done with your workout. Bonus: When your metabolic rate becomes faster due to muscle growth, you’ll have a little more wiggle room in your diet if that’s something you struggle with, says Dr. Cheskin.
That’s because it theoretically causes a mild ketosis (yep, the basis of the keto diet), which is a fat-burning state that should make you feel less hungry. The key in being successful with a low-carb diet (especially if you’re used to a more high-carb lifestyle) is to compensate for those lost carbs with protein-rich foods, says Dr. Cheskin. That way, your volume of food stays the same, but you’re doing it healthfully rather than in a way that exacerbates your weight gain.
Health professionals laud Weight Watchers focus on a balanced diet that they say is easier to stick to than plans that restrict food groups. The latest update to the program adds more than 200 "free" foods that you don't have to limit or track. Weight Watchers strongly encourages exercise and the diet plan is easily customized. The point-based system is easy to follow, and the basic program is relatively affordable. The most important feature of the Weight Watchers plan is ongoing support, in physical meetings and/or online.

In general, losing weight by following a healthy, nutritious diet — such as the Mayo Clinic Diet — can reduce your risk of weight-related health problems, such as diabetes, heart disease, high blood pressure and sleep apnea. If you already have any of these conditions, they may be improved dramatically if you lose weight, regardless of the diet plan you follow.
Acai had a major health food moment, thanks to the incredibly delicious acai bowl, which is basically a super thick acai berry smoothie mixed with nuts, oatmeal, and fresh fruit. But not only does acai cost a lot more than other berries, it doesn’t quite live up to all of its hype. “Acai has been touted for many benefits, including aiding in weight loss, but there is no evidence that this berry will have you shedding pounds,” says Amidor. Find out exactly what food to buy at the supermarket to lose weight.
14 ways to lose weight without diet or exercise Strict diets can be challenging to follow, and people may not always have the time or ability to exercise. However, a variety of simple lifestyle changes can help people lose weight and improve their health. These include taking probiotics, getting enough sleep, and thoroughly chewing food.
