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. 

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.
Not much of a coffee drinker? Tea is also a natural diuretic, and types of herbal tea such as dandelion or fennel root can also lend a hand. In fact: When a recent study compared the metabolic effect of green tea (in extract) with that of a placebo, researchers found that the green-tea drinkers burned about 70 additional calories in a 24-hour period.
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.

Variety: Nobody wants to eat the same thing day in and day out. That's why a variety of food items is essential for a diet plan to be sustainable. Also, variety as a criterion for determining the best diet plans refers not only to food items but also to groups of people. For example: Is the diet plan available to diabetics? Men? Women? People with allergies or special conditions?
Okay, you get the point: belly fat = bad. How do you lose it? You have to think beyond crunches and planks and adopt a well-rounded approach. “It’s got to be more losing fat as a whole,” agrees Chris Gagliardi, a certified personal trainer at the American Council on Exercise (ACE). Without further ado, here are the best ways to lose belly fat once and for all.
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.
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.
The most unique aspect of Noom is that it lets you communicate with your personal coach via text message as many times as you want, so you can work hand in hand towards your goal without missing a step. Sometimes, a simple word of advice or support can make all the difference, especially during the stressful moments that inevitably happen during a strict diet. Also, in case you forget to log in your foods, the app will send you reminders via pop up messages.
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.
Sure, you certainly need to drink plenty of water to help combat bloating, you can (and should!) also consume high-water content foods. Reach for cucumbers, tomatoes, watermelon, asparagus, grapes, celery, artichokes, pineapple, and cranberries — all of which contain diuretic properties that will also help you stay full due to their higher fiber content.
We're pairing two Trader Joe's fan-favorite products--the Middle-Eastern Balela salad with beans and spices and 10 Minute Farro--to add protein, fiber and satisfying texture to these high-protein lunch bowls. To cut down on prep time, we're also using pre-seasoned grilled chicken breasts from the refrigerated section, bottled balsamic vinaigrette and a few other ready-to-use ingredients you can find at Trader Joe's to make these quick and easy meal-prep lunches.

"Whether it's an app or paper food logs, tracking what you eat will certainly be eye-opening. Almost everyone consumes more than they think. Write everything down as soon as you're done eating so you don't forget anything. The simple act of recording what you eat will make you eat less. When the calories are in your face, it makes you think twice!" — Martha McKittrick, RD, CDE
"Eat vegetables before or with meals. Whether you are hungry on your way home or right when you walk in the door, snacking on veggies can help you keep your portions in check once you sit down to a meal. I also recommend starting your dinner with a vegetable salad or vegetable soup to fill you up and prevent overeating. — Ilyse Schapiro, MS, RD, CDN, author of Should I Scoop Out My Bagel?

Phase 2: During this phase some carbs are back, so you have to watch out for any weight gain. (Following the strictness of Phase 1, you might be inclined to overeat your favorite carb-filled foods). You’ll get to eat no more than 50 grams of “good carbs” per day, including whole grains, beans, and fruits. Still, the bulk of your diet will consist of lean proteins, good fats, and vegetables.
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!"
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.
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.
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.
If you have more than a week to lose 10 pounds, Dr. Huether recommends trying intermittent fasting. "For longer-term weight loss and maintenance, I like to use intermittent fasting where I choose an 8-hour window to eat (for me its 1 pm to 9 pm). By doing this your body learns to use fat as fuel (instead of glucose), so it becomes easier and sustainable over time."
“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.
Based on the concept of caloric density, which states that some foods have few calories in proportion to their size (say, a lettuce), while others have lots of calories packed in small portions (a regular chocolate chip cookie comes to mind), Volumetrics divides foods into 4 categories based on their calorie/volume ratio, and is perfect for people looking to binge on some foods while still shedding pounds. However, as with the calorie counting approach, Volumetrics does not take into account the quality of the calories, prioritizing quantity instead. The app Noom and Weight Watchers (both reviewed above) share similarities with this diet theory.
"Stop focusing on calories and start focusing on the quality of the foods you eat. High-quality diet options are natural, whole, minimally processed foods, like vegetables, fruits, nuts or seeds that offer a lot more nutritional value in the form of vitamins, minerals, healthy fats and fiber. These foods help tame hunger naturally and nourish our cells at the deepest level so that we aren't left with constant cravings. — Michelle Loy, MPH, MS, CSSD, Registered Dietitian Nutritionist and owner of Go Wellness in Orange County, California

“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.”

This high-fat, adequate-protein, low-carb fad diet sends the body into a state of ketosis, in which the body uses stored fat for energy. Research published in Clinical Cardiology suggests the ketogenic, or “keto,” diet can be an effective weight loss method, but to be successful, you must follow the plan consistently with no cheat days — otherwise, you’re just eating a high-fat diet that may be high in unhealthy fats for no reason. (1) (A pro tip? If you're planning on doing the diet, consider perusing this complete keto food list and reading up on the healthiest fats for keto diet followers.)

The TLC approach, contained in the 80-page manual “Your Guide to Lowering Your Cholesterol with TLC,” recommends less than 7% of daily calories from saturated fat, less than 200mg of cholesterol, 30 minutes of daily exercise, and drug treatment when necessary. However, critics of the low-fat plan point to its shunning of healthy high-fat plants and its ignoring of the fact that it's calories, and not fat, what determines whether or not a person loses weight.


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.
