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.

Getting enough protein every day, whether you’re in a quick-fix or long-term mindset is important for keeping your muscles and metabolism healthy throughout weight loss. Make sure you’re having some chicken breast, lean ground turkey, fish, seafood or tempeh that’s the size of a deck of cards at every meal. When snacking, have 2 eggs, 1/4 cup of nuts, or 3/4 cup of Greek yogurt or cottage cheese to meet your protein needs and stay full and feel slim.
Aim to get at least seven hours of sleep each night. Try going to bed and waking up at the same time each day. 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.
To avoid feeling hungry after a workout, eat a snack with at least 12 grams of protein before exercising, says Dr. Cheskin. And if you’re still hungry afterward? First, check in with yourself and make sure it’s actual hunger and not dehydration, says Dr. Cheskin. Then, eat a protein-rich snack that also includes some carbs, like a protein bar with whole grains.

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.
"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."
CBS News takes viewers inside the real-life challenges facing migrant families split apart by the Trump administration's "Zero Tolerance" policy. The documentary provides an immersive look at the hotly debated issue through the eyes of those impacted the most — the fathers, mothers, sons and daughters separated and unaware when they'll see their family members again.
"It's no big surprise, but my go-to weight loss tip is to eat more vegetables. They are the most low-calorie food you can consume, and they're filled with health-boosting, satiating nutrients. From smoothies and eggs to soups, main and side dishes, they can fit in anywhere and boost volume and nutrition. If you want to eat more while still losing weight, veggies are your answer. —Laura Burak, RD, CDN
Based on my experience in nutrition counseling, most of us tend to snack on foods that aren’t nutrient-dense, but are high in calories. For example, skipping sugary beverages is often the easiest way to lose weight faster. You don’t feel full from drinks — even the ones that do contain calories — so swapping those out for sparkling water or unsweetened tea and coffee is the best place to start. Other major culprits often come in refined grains like cereals, chips, crackers, and cookies.

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."


"A study published in Nutrition Journal found that participants who ate foods high in monounsaturated fats for lunch (in this case, half an avocado) reported a 40 percent decreased desire to eat for hours afterward. Monounsaturated fats from sources like olive oil, nuts and avocados can reduce cholesterol, promote weight loss, even boost memory." — David Zinczenko, author of the Zero Belly Cookbook
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.
Eat like the Italians and the Greeks! This is the dietician’s darling, named #1 non-commercial diet by many experts in the health and weight management industries. It's not a fixed diet with a fixed menu, but rather a general guideline based on fruits, vegetables, beans, nuts, healthy grains, fish, olive oil, red wine (yes, red wine), and small amounts of meat and dairy. It is one of the most flexible diet plans out there, as it is highly customizable to fit anyone’s tastes and needs. It does not require calorie counting, mainly because most of the foods in this diet are filled with fiber and healthy fats, which makes you digest them slower, so you feel fuller longer.
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?
Created in 2003 by cardiologist Arthur Agatston, this low-carb diet features three phases. The first phase is the most restrictive, limiting carbs such as potatoes and rice. Each subsequent phase becomes more lenient, and the diet emphasizes lean protein, unsaturated fats, and low-glycemic carbs such as nonstarchy vegetables. South Beach promotes lasting lifestyle changes, according to the Mayo Clinic. (21)
When we began our research on Nutrisystem, the first thing that stood out to us was the variety of  plans they offer. In total, there are nine different options, including plans for diabetics, vegetarians, and even special diets for men (a rarity in the diet industry). Also, most of their plans are highly customizable, so if you don’t like their recommendations you can customize your meal plan from chef-created menu items including staples like chicken masala, cheesesteak pizza, muffins, burgers, popcorn, and lots more.
However, the most unique aspect of Diet-to-Go is its freshness, as all meals are prepared in-house and flash-frozen so preservatives never have to be added. This freezing process allows for fresher foods that last longer and taste more natural. What’s more, Diet-to-Go’s kitchens adhere to several guidelines for food safety and handling, including the HACCP, USDA, and FDA.
For Americans and most people all over the world, losing weight remains the number one New Year’s resolution. With 50 million Americans getting on a diet each year, it'sno wonder that dieting has become a $72 billion industry. What's surprising, though, is that regardless of resolutions and the billions spent, obesity is on a steady rise in the U.S., to the point that it has now become a “national epidemic.”
The best diet for losing weight is Weight Watchers, according to the experts who rated the diets below for U.S. News. Volumetrics came in second, and the Flexitarian Diet, Jenny Craig and the vegan diet were third on this overall weight loss ranking list, which takes into account short-term and long-term weight loss scores. Some other diets performed as well or better in our rankings for enabling fast weight loss, but long-term weight loss is more important for your health.
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.

Real talk: It could take weeks or months to see the metabolic effects of exercise on the scale, and even then, building muscle, which is denser than body fat, could lead to weight gain. "Do what you like because it’s good for you," Dr. Seltzer says, noting the way exercise is awesome for your heart, mental health, and more—and that not all measure of progress can be seen on the scale.
"These diets are so restrictive that of course you're going to lose weight fast because you're not eating enough calories to sustain basic activities of your body, let alone any exercise. That's nothing that any person can sustain for the long term," Hogan said. "The weight's going to come back if you do lose any weight, and then it's going to be harder to lose weight in the future."
Forget old low-carb diet plans that focused on processed protein bars and shakes. This year, the keto diet got high marks for low carb. Keto, short for "ketogenic," is all about training the body to burn fat for fuel. How? By eating fat—and lots of it. Most keto diets recommend getting at least 70 percent of your daily calories from fat and the rest from protein. The goal is to eat as few carbohydrates as possible. Proponents say it helps them drop weight fast with little or no hunger in addition to perks like more energy and mental clarity. (Interested? Here's everything you need to know about the keto diet.)
DASH stands for "dietary approach to stop hypertension" and was created by the National Institutes of Health (NIH) as a way to help reverse national trends of obesity and heart disease. Scientists combed through decades of research to come up with an expert-backed list of diet tips, along with a prescription for exercise. And it worked: The DASH diet has topped nearly every diet list for nearly a decade. Doctors particularly recommend it for people looking to lower high blood pressure, reverse diabetes, and lower their risk of heart disease. (Here's the basic list of DASH diet-approved foods.)
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.)

"Keep track; whether that's every day, week or two to make sure you're on track and if not go back over your plan of action and tweak it; nothing's set in stone and it has to work for you not someone else! If it's not working, reassess other alternatives that do. There are many routes to the same destination. This doesn't mean giving up on your goals, it means finding new ways to achieve them that works for you." — Eve Dawes, Certified Personal Trainer, NASM, founder of Fitness By Eve.

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.
