Swapping out unhealthy foods for nutritious ones gives you benefits beyond just losing weight. "I cleaned up my diet, swapping deli sandwiches with high-sodium meat and mayo for Tupperware containers or big butter-lettuce salads topped with carrots, walnuts, feta, and homemade dressing," says Jennifer Lasher, who lost 75 pounds. "I found that ditching processed foods left me with more energy, a clear head, and better skin, too."

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)!


In a new study, Stanford University researchers put more than 600 overweight adults on either a healthy low-fat or low-carb diet. It turns out, participants had similar levels of weight loss success on each plan. Researchers looked for clues (such as insulin levels and gene patterns) to see if there are any factors that might make someone more successful on either diet, but after combing through the data, they were not able to make any connections. Since it may take years before scientists discover individual traits that could lead to more success on one plan compared to another, for now, we can learn a lot — and lose a lot! — by recognizing the dieting advice that all experts agree on.
Popcorn is a whole grain, so it’s not unreasonable to include it on your green-light food list. However, even “natural” and “light” microwave popcorn is loaded with artificial ingredients, plus sodium and butter—and a ton of calories. This doesn’t mean you have to give up all popcorn though, as air-popped popcorn is a much better alternative. It only contains 30 calories per cup and you can customize it to your liking.

The main advantage of the low-carb diet is that it causes you to want to eat less. Even without counting calories most overweight people eat far fewer calories on low carb. Sugar and starch may increase your hunger, while avoiding them may decrease your appetite to an adequate level. If your body wants to have an appropriate number of calories you don’t need to bother counting them. Thus: Calories count, but you don’t need to count them.
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."
Any movement counts. The numbers are daunting: The 2018 Physical Activity Guidelines for Americans suggest a minimum of 150 minutes (2.5 hour) of moderate-intensity aerobic activity a week (walking briskly, playing doubles tennis, raking leaves), or 75 minutes (one hour, 15 minutes) of vigorous-intensity activity (running, a strenuous fitness class, carrying groceries up stairs), as well as muscle-strengthening activities (resistance training and weightlifting) two days a week. But if you want to lose weight, work up to 300 minutes of moderate-intensity activity a week, or 150 minutes of vigorous-intensity activity. “But doing something just a few minutes a day to get started has benefits,” said Piercy. “So parking farther away when you’re running errands, getting up from our desks and going down the hall instead of sending an email -- those are things people can start incorporating into their daily lives now that may be a little easier than saying, ‘Oh my gosh, I have to figure out how to fit 2.5 hours of activity into my week.” If you are starting from zero physical activity, Dr. Jakicic suggests taking a 10-minute walk five times a week, shooting for 50 minutes a week, and building on from there once it becomes habit.
Vegetables, preferably wild or organic and raw, should make up more than half of your plate. The majority of bulk should come from fresh green, leafy, vegetables such as kale, spinach, leaf lettuce, bok choy, collard greens, and other greens. Colorful vegetables are excellent, but limit starches, especially white potatoes and corn. Fresh veggies are best, but steamed, lightly cooked, frozen, and canned without preservatives or additives work, too.
Some antidepressant medications can cause weight gain, especially the older tricyclic antidepressants (TCAs) such as Tryptizol, Saroten, and Clomipramine; as well as newer drugs such as Remeron (Mirtazapine). Lithium (for manic-depressive disorder) often causes weight gain. The most common antidepressants known as SSRI’s (for example Citalopram and Sertraline) usually don’t impact weight significantly.

Everyone loves to create exercises that make working out more fun. And that’s fine; your workout should be enjoyable. But thinking that Bosu ball balancing acts or one-legged plié jumps while holding a kettlebell will get you fitter faster just isn’t accurate. If you want results, you have to stick with what we know works. And that’s classic, multi-muscle exercises like squats and deadlifts. These exercises work because they force you to use multiple muscle groups at once. And the more muscles you activate, the more fat you’ll slash.
Interested in following a more historical approach to eating? The Primal Blueprint is similar to the Paleo diet, which has roots in how our long-ago ancestors supposedly ate. This plan ditches grain, sugars, and processed foods while focusing on clean eating with plenty of protein (both animal- and plant-based), lots of vegetables, fruits, and healthy fats. The Primal Blueprint acknowledges other health factors too, advocating for lots of low-intensity activity, some high-intensity exercise, strength training, and plenty of sleep.
In other words? "Drinking makes you more likely to eat sh*t," Dr. Seltzer says, referring to drunk foods. At the same time, he stops short of asking patients to quit alcohol cold-turkey to lose weight. Plus, research suggests you don’t have to, as long as your intake is moderate—i.e., less than about a drink a day. "If you drink a glass of wine every night and notice you eat more afterward, eat less early to account for this," he says. "Or, if you’re drinking four glasses of wine a week, drink three instead so you’ll won’t feel such a big difference."
Thank you Abel. I am finishing reading your book at this moment. I am encouraged because it sounds very doable. My family is in an overweight crisis and we need change drastically. My husband and daughter are both 200+ pounds over weight. Neither one of them are able to exercise so I am hoping that they will stick with this and lose weight without exercise for a while. Food cravings and hunger are big for them so educating ourselves on managing them is critical. I need to lose 20 pounds. We are working on this and have enjoyed your recipes greatly. We are all learning portion control as well.

The purpose of the Mayo Clinic Diet is to help you lose excess weight and to find a way of eating that you can sustain for a lifetime. It focuses on changing your daily routine by adding and breaking habits that can make a difference in your weight, such as eating more fruits and vegetables, not eating while you watch TV, and moving your body for 30 minutes a day.
While not everyone has time to spend two hours at the gym every day, it is still possible to get enough daily activity to help your body burn off unwanted belly fat.  Try to fit in three five minute sets of vigorous exercise per day, five days out of the week.  Some great examples of workouts that will get your heart pumping and help you lose belly fat include:

"What I don't like about any commercial diet is that the focus is not on your actual food choices," Hogan said. "It's about calories or points or numbers, and that really takes away from your ability to be in tune with your hunger cues and your fullness cues and what you're really craving. If we become more in tune with those things, we naturally consume how much the body needs. Paying too much attention to numbers takes away from that."


Keeping a toothbrush handy can do more than polish up that smile (and counter the effects of all that belly-slimming garlic); brushing your teeth throughout the day can also help you ditch that belly fat fast. A study conducted a sample of over 14,000 participants found that brushing after every meal was linked to lower weight. That minty toothpaste flavor not only clashes with virtually every food, brushing may also trigger a Pavlovian response that tells your brain the kitchen’s closed.
Good article Monique! While I agree with on “The best diet is the one we can maintain for life” not everyone can start eating healthy right away. In my opinion quick diets and fast weight losing methods have their own place. I studied in Harvard over ten years ago and have a plenty of love for the school and community, but you should not say no to fast diets right away. I was overweight for a long time because I just couldn’t change my habits. It was when I tried the 2 week diet plan that I started seeing results for the first time. After losing few pounds I became motivated and now I have lost a lot more weight. Even if you are skeptical I would recommend you checking it out, if you are overweight.

Also, the natural sugar in fruit does affect your carbohydrate intake — especially if you eat a lot of fruit. This may temporarily raise your blood sugar or certain blood fats. However, this effect is lessened if you are losing weight. If you have diabetes or any other health conditions or concerns, work with your doctor to adjust the Mayo Clinic Diet for your situation. For example, people with diabetes should aim for more vegetables than fruits, if possible. It's a good idea to snack on vegetables, rather than snacking only on fruit.
If you don’t have an established exercise routine, simply walking is the best first step toward weight loss. “Walking is a pretty good entry point for people,” says Gagliardi. This is particularly true if you have been out of the gym for a while and want to ease back into a workout routine. One small study published in The Journal of Exercise Nutrition & Biochemistry found that obese women who did a walking program for 50 to 70 minutes three days per week for 12 weeks significantly slashed their visceral fat compared to a sedentary control group.
Many people dread the thought of New Year, knowing they’re going to try and commit to a weight-loss plan or diet to shed the extra pounds accumulated during the festive season. Last year, a YouGov poll revealed that 37% of Americans decided they wanted to either eat healthier or exercise more and it’s unlikely those statistics will change much going into 2019.
HIIT, or high-intensity interval training, has been called the secret weapon of fat loss. HIIT alternates between short, intense anaerobic exercises, such as sprints, with less-intense recovery periods. This method of exercise raises your heart rate and allows you to burn more calories in a shorter period of time. And if losing loads of calories in a short period of time wasn't enough of a reason, HIIT offers many other benefits as well.
The U.S. Department of Health and Human Services warns that women with a waist measurement of more than 35 inches and men with a waist measurement of more than 40 inches may have an increased risk for obesity-related diseases. While overall weight loss is the only known way to fight abdominal obesity and protect against obesity-related diseases, some research suggests that certain natural solutions may help reduce belly fat. Here's a look at several study findings:
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.”

You will feel hungry sometimes, but you can eat more fat if you do. The first three days, you may need L-glutamine. If your body is really toxic, you may feel headaches or like you got the flu. It passes in a couple days. If you need painkillers, go for aspirin, NEVER Tylenol. Tylenol will hurt your liver and make it hard to detox because it depletes glutathione.
I can tell you this…Everyone is different, however, I went on a 3 week JUICE FAST while nursing. I made sure to eat 1-2 tablespoon of good fat (raw almond butter, mashed avocado) to keep my energy levels up. I included my breastfeeding teas like Mother’s Milk and Fenugreek). I never had a problem producing, I lost weight extremely fast, my skin looked beautiful, I was very calm and relaxed. I like it would be an awesome idea even tho I am not a doctor.
Stress causes our bodies to pump out a hormone called cortisol which causes us to build and retain belly fat.  If you’ve tried every health food, trick, cheat, and exercise under the sun but you just can’t seem to lose the weight around your waist, relax.  It may be the stress itself that is to blame.  Instead of worrying about your weight, set aside some time each day to do something you love.  Think about what makes you happy and find a way to include that in your daily routine.
Social conditions such as poverty, social isolation and inability to get or prepare preferred foods can cause unintentional weight loss, and this may be particularly common in older people.[43] Nutrient intake can also be affected by culture, family and belief systems.[28] Ill-fitting dentures and other dental or oral health problems can also affect adequacy of nutrition.[28]
In addition to helping maintain heart health and keep inflammation levels under control, monounsaturated fatty acids, or MUFAs, may stop belly fat before it starts. Research in the journal Diabetes Care found that people who got roughly 25 percent of their total daily calories from MUFAs gained no visceral fat over the course of the study, while those who ate less MUFAs and more carbs added fat to their midsections. My favorite MUFA-rich food is olive oil because you can use it in so many meals (check out the belly-blasting breakfast I recommend), but avocados and nuts are other excellent sources. Pine nuts are particularly great because they also contain high levels of polyunsaturated fatty acids. These acids increase levels of two hormones that signal your brain when you’re full. Try snacking on one ounce of pine nuts (about the amount you can fit in a shot glass) 20 minutes before mealtime to avoid overeating.
