We pulled the top 14 of the best commercial diets (marketed to the public for profit) and the top 12 of the best diets overall. We also threw five of the most popular diet apps into the mix. Since these are largely tracking devices that don’t espouse unique eating habits, they don’t appear to meet US News’ definition of diet, but are still potentially effective weight loss tools.

If you’re a guy, you can thank the testosterone you have -- and the extra estrogen you don’t -- for your weight-loss edge. On average, women have between six and 11 percent more body fat than men, an assumed evolutionary adaptation to help during pregnancy. From puberty to menopause, women maintain more average body fat than men -- even when they take in fewer calories.
Aim to get at least seven hours of sleep each night. Try going to bed and waking up at the same time each day. Get these seven tips for the best sleep ever! Why? Ever notice how you start to crave donuts and drive-thru breakfasts when you’re exhausted? When you don’t get enough sleep, your hormones are thrown out of balance. Running on no sleep can actually drive up the hormones that make you want to eat, while pushing down the hormones that signal for fullness—and that’s a recipe for weight gain. When you’re well-rested, it’s much easier to make healthy decisions and stay on track.

There was also weight loss supplements that wouldn’t kill you, but didn’t really work either. Green coffee, raspberry ketones and grapefruit extract all come to mind. They sound great, but they all turned out to be pure hype. One substance, though seems to have stood the test of time — green tea, with traditional Asian medicine touting the weight loss effects for thousands of years.


If you can keep up motivation and accountability without the assistance of an app or a like-minded community, the book should give you all necessary tools. While we weren’t floored by Mayo’s online offerings, the app does have one cool feature (if you can get it to work): Enable your camera to eyeball the correct size of any food item in comparison to a virtual baseball, hockey puck, set of dice.
Sure, there's your one friend who swears by the Taco Cleanse. And that other friend who ate nothing but broccoli soup for a month and dropped 20 pounds, found the love of her life, and got promoted at work. But before you start blending 80 stalks of broccoli into a cup or crunching your way through a crate of tacos, check out which diets are backed by science. Because don't you want to try one that will do the trick for you?
Some green tea varieties are better for weight loss than others. If you’re all about that green and on a weight-loss mission, you might want to choose Matcha green tea—the richest green tea source of nutrients and antioxidants. Registered dietitian Isabel K Smith explains why: “The whole leaf is ground and consumed as part of the beverage, as opposed to other (most) types of green tea where the leaves are steeped and then the tea is consumed.”
Studies on green tea’s impact on cancer have been mixed. But green tea is known to aid healthy cells in all stages of growth. There are some clues that green tea may help destroy cancer cells, but that research is still in its early stages, so you shouldn’t count on green tea to prevent cancer. In fact, the National Cancer Institute's web site says it "does not recommend for or against the use of tea to reduce the risk of any type of cancer." 

Coconut oil is having a moment right now: it can be used as a butter or olive oil substitute in everything from baked goods to salad dressing, and can even be used as an alternative to milk in lattes (yes, really). Sass is a fan of the heart-healthy oil whipped into smoothies, and you can also use it to sauté veggies, sear fish, or as an olive oil replacement in soups and stews. (It's also a must-add to your beauty routine, and makes a wonderful natural moisturizer for skin and hair.)

Lipton green tea is loaded with epigallocatechin gallate (EGCG), a catechin that is found in green tea. It helps your body to burn fat and increases your body’s insulin sensitivity (3). EGCG has also been found to inhibit fatty liver disease in lab rats (4). If you are a beginner, then the green tea containing honey and pomegranate is a better option for weight loss. But all the variants have the same impact on your body.

Think of each almond as a natural weight-loss pill. A study of overweight and obese adults found that, combined with a calorie-restricted diet, consuming a little more than a quarter cup of the nuts can decrease weight more effectively than a snack comprised of complex carbohydrates and safflower oil—after just two weeks! (And after 24 weeks, those who ate the nuts experienced a 62% greater reduction in weight and BMI!) For optimal results, eat your daily serving before you hit the gym. A study printed in The Journal of the International Society of Sports Nutrition found that almonds, rich in the amino acid L-arginine, can actually help you burn more fat and carbs during workouts. Fill up, but don’t fill out: Use these Eat This, Not That!-recommended 10 Daily Habits That Blast Belly Fat.
Consequently, researchers have widely discredited the hCG diet, which involves using hCG injections, pellets, sprays, or drops, and consuming  as few as 500 calories daily. The diet is problematic not only because there’s a lack of research on hCG supplements, but also because  the calorie requirement is dangerously low, potentially leading to nutrient deficiencies, fatigue, hormone imbalances, blood clots, and other issues. Thus, most experts agree the hCG Diet is not safe for anyone, the Mayo Clinic notes. (35)
Weight Watchers, The Mayo Clinic Diet, and especially Noom provide a lot of behavior-based support to integrate these good habits. These include learning portions, logging food, and both giving and receiving external support. Nutrisystem doesn’t ask for any behavior changes save for subsisting almost entirely off their pre-packaged, pre-portioned meals.

Is there anything avocados can't do? This creamy superfood (loaded with monounsaturated fats, potassium, magnesium, folate, and vitamins C and E) has been linked to improved vision, good heart health, and a reduced risk of certain cancers. And avocados can also help whittle your middle: according to one study, people who regularly consume them weigh less and have smaller waists than those who do not. Another study found that women who eat half an avocado at lunchtime might experience reduced food cravings later in the day.
“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 

It’s important to eat ad libitum. We shouldn’t stuff ourselves, but we do need to feel comfortably full. Otherwise, we end up crazy-hungry. But unfortunately, ad libitum eating is not what traditional weight-loss strategies have taught us for the past 100 years. Dieters have been told to focus mainly on how much they eat rather than on what they eat. They’ve been told to cut portion sizes and/or use their will power to override hunger in an attempt to create a negative calorie balance and reduce body fat stores.
To reach your get-lean goal, you must also follow a get-lean diet, filled with the best foods to burn fat. Why? Even if you work out hard for an hour every day, that still leaves 23 more hours for you to wreck all your hard work in the gym with just one slip-up: a measly handful of chips, a beer with the guys, or a burger at lunch. Diet is a huge, so to speak, part of the fat-loss equation. It's the backbone of your entire plan, the foundation of a hard body.
Don't get me wrong — exercising at any time is good for you. But evening activity may be particularly beneficial because many people's metabolism slows down toward the end of the day. Thirty minutes of aerobic activity before dinner increases your metabolic rate and may keep it elevated for another two or three hours, even after you've stopped moving. What that means for you: You're less likely to go back for seconds or thirds. Plus, it'll help you relax post meal so you won't be tempted by stress-induced grazing that can rack up calories, quickly.
“If weight loss is the goal, I recommend learning how to properly deadlift. Deadlifting recruits more muscle fiber at once than any other exercise. More muscle working equates to more blood flow, an increased heart rate, more metabolic demand and output. It’s compound, multi-joint and more bang for your buck, not to mention you’ll develop an excellent posterior from them.” — Victoria Viola, PN Certified Nutrition Coach, NSCA CPT, Co-Founder, Excelerate Wellness, LLC
Want to lose weight? Grab a bottle of V8! According to a study published in Nutrition Journal, tomato juice consumption can aid weight loss because it increases resting energy expenditure (REE)—the amount of energy expended by a person at rest. After eight weeks of drinking unsalted tomato juice twice daily, the 95 women in the study (who were each exhibiting some menopausal symptoms) increased their REE by an average of over 100 calories per day. 

Did you know turnips could help you shed belly fat? Their high vitamin C and phytochemical levels help detoxify your body—and too many toxins in the body can lead to fat accumulation around your waist, says Maleeff. At only 34 calories and 8 grams of carbohydrates per cup (vs. a potato’s 113 calories and 26 grams of carbohydrates), try making mashed turnips instead of mashed potatoes for a nutrient-dense, low-calorie alternative, suggests Maleeff.
Preheat oven to 400°. Slice 1 small potato into fry shapes; toss with 1 teaspoon olive oil and 1 teaspoon chili powder. Roast on baking sheet until golden (about 30 minutes). Grill 1 (3-ounce) sirloin steak until desired degree of doneness; slice into thin strips. Fill 6 Romaine lettuce leaves with steak. Top with 1/2 cup thinly sliced red bell pepper; drizzle with 1 tablespoon balsamic vinaigrette.
A fat-burning superfood, grapefruit contains a compound that can lower the fat-storage hormone insulin, which in turn can lead to weight loss. In fact, eating half a grapefruit before each meal could help you lose up to a pound a week—even if you don't change anything else about your diet. Because grapefruits are 90% water, which fills you up, they also act as a natural appetite suppressant.

Yogurt is protein-packed and full of probiotics, which are good for gut health and may help your weight-loss efforts. Your gut health can impact your weight, and eating more fiber and probiotics helps keep your gut bacteria happy, which can be good for your metabolism (read more about your gut-weight connection). Go Greek for more protein; plus, research from Appetite found that consumption of Greek yogurt was associated with reduced appetite and increased satiety. Just keep an eye on added sugars in flavored yogurts, which only add calories. Instead, use fresh fruit to sweeten plain yogurt.
Becky–this is a great quick start plan. I want to lose 5 pounds I put on after a recent weight loss. It’s very balanced with lots of plant protein as well as animal protein. My only comment is that it’s a lot of fiber very quickly, and I know that this would cause me intestinal pain, especially from raw veggies. It’s so advantageous to have these available by prepping, so I will eat smaller portions (1cup carrots is too much for me at 120 lbs), chew them well and eat slowly and save the rest in case I am still hungry before the next meal! For people who are used to eating more food, I’m wondering if they are able to handle the fiber better than someone like me who has already learned to cut way back on portion sizes!
The active compounds in green tea aids in the process of breaking down fat in the fat cells, thereby moving them into the bloodstream. Hence, we can conclude that green tea contains bioactive substances like caffeine and EGCG, which have powerful health impacts. They mobilise the movement of fat content into the fat cells thus making it easier for them to produce energy, and releasing it throughout the body to be used by other cells.
One basic reason may be on account of caffeine is a stimulant. This implies it will give more sharpness and can expand your stamina, both of which can help the power and length of exercises. A portion of the investigations, notwithstanding, demonstrate that the green tea helps consume calories while very still too, which implies that notwithstanding when you are not sweating at the rec center, green tea may enable you to get in shape.
Tea is the second most-consumed drink in the world, preceded only by water. And green tea, one of the most popular of the teas, contains nutrients that supposedly help melt away pounds. Unfortunately, research shows that the tea may not be the solution to your weight problem, and it's no replacement for a healthy diet and exercise program. If you're struggling with your weight, talk to your doctor for suggestions as to how to go about losing it and whether green tea makes a healthy addition.

A simple way to slim down: Eat the rough stuff. Simply adding more fiber to your diet can lead to weight loss. That’s because your body can’t break down fiber, so it slows down digestion and takes up space in your stomach. With 4 grams of fiber per cup, oatmeal can be a good source. Walnuts can add about another 2 grams, plus satisfying protein and crunch.
“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.”
Finally, some chapters I have no problems with! Chapter 6 has some good advice on how to create and use a food diary, and not just to record what you're eating, but to find out what your bad habits are so you can start to recognize them and fix them. I'll be honest, I'm not even aware of the bad habits I have related to how I eat (not just what I eat) and this method is actually good advice on how to achieve it without shaming anyone or making assumptions and generalizations! Chapter 7 is all about stopping food cravings with some great advice. Chapter 8 provides some great advice of creating a physical activity habit (throwing the entire without working out part out the window, but hey, what's a little misleading advertising to get you to open the book. I mean, we already discovered that the whole title was a scam when the author promised to help you lose weight fast yet tells you not to lose weight fast). Chapter 9 provides some decent information about nutrition, though I think this is a far bigger topic than what could be covered in a short chapter of a book.
Wouldn’t it be great if life came with a magic remote control that made the bad parts speed up and the good parts slow down? You could hit FF at the beginning of every workday, and RWD at the end of awesome date. All the vacations, holidays and parties could move at the pace of a Kenny G song, and all the endless conference calls could spin by faster than Nicki Minaj’s hairstyles.

"If you are drinking lots of fluids, these liquids will fill you up and send a regulatory hormone to your brain that tells it that you aren't hungry, which could mean you eat less," Zeratsky explains. "Also, if you're well-hydrated, your body won't confuse hydration with being hungry which could also lead to consuming less...But, ultimately, a balanced diet and exercise are the most important."

MyFitnessPal: An app widely recommended by trainers and fitness enthusiasts, MyFitnessPal is great for tracking macros. Goal macros: 50% carbs, 30% fat, 20% protein. It further breaks these general guidelines into specific gram amounts that make it easy to see how some macros add up quick (carbs) and others don’t (protein — hitting 64 grams takes conscious effort!).

A myriad of different teas have been shown to aid weight loss, and green tea is no exception. In fact, a study published in The Journal of Nutrition found that after just two weeks, those who sipped four to five cups of the green brew each day, in addition to working out for 25 minutes, lost more belly fat than those who didn’t imbibe. Scientists attribute green tea’s ability to shrink waists to the beverages catechins, a type of antioxidant that hinders the storage of belly fat and facilitates rapid weight loss.
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. 

You may not think of them as a weight-loss food, but eggs are packed with protein, which helps curb your appetite. One study found that overweight women who ate eggs for breakfast were able to lose twice as much weight as women who started their days with bagels. And egg whites in particular are a good source of branched-chain amino acids, which help keep your metabolism running smoothly.
The fad military diet consists of low-calorie, odd food pairings such as bun-less hot dogs with banana, carrots, and broccoli. “Any diet like the military diet that severely limits the amount of calories you consume or eliminates one or more entire food groups puts any individual at risk for nutrient deficiencies,” says Kyle. “This can be more harmful than holding onto those 10 extra lbs you’re trying to lose.” (32)
“The American Heart Association recommends that men eat less than 36 grams of added sugar and that women consume less than 24 grams. However, for optimal weight loss, I tell my male clients to consume less than 20 grams of sugar per day and I tell the women to consume less than 15 grams.The easiest way to cut back on the sweet stuff is by consuming less sugary drinks and dressings. Cut the sugar, lose the fat, regain your health and life.” — Dr. Sean M. Wells, DPT, PT, OCS, ATC/L, CSCS
What if we told you that you could make 20 percent of your belly disappear this year—poof, just gone? Penn State University researchers compared those who consumed avocado oil with those who consumed a flax-safflower oil blend. Those on the avocado oil diet—just three tablespoons daily did the trick—lost nearly 2 percent of their belly fat in just one month.

Studies led by Dr. Barbara Rolls at Pennsylvania State University as well as those of Drs. James Barnard and Christian Roberts at UCLA, who are following people attending the Pritikin Longevity Center, are particularly enlightening. They have documented that one of the best ways of reducing calorie intake without triggering increased hunger is to reduce the calorie density of the foods consumed. Put simply, a bowl of pasta with veggies and marinara can fill us up just as well as a bowl of pasta with cheesy Alfredo, but for less than half the calorie cost.
