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.)
With this eating style, you’re looking at a lot of menu planning and preparation. A review published in August 2017 in Nutrients suggests the diet could lead to weight loss, but the Academy of Nutrition and Dietetics warns the plan could also cause certain nutrient deficiencies, such as in calcium and vitamin D. (3,4) And, therefore, according to an article published in the January–February 2016 issue of the Royal Australian College of General Practitioners, anyone at risk for osteoporosis should avoid it.

Because of its focus on frequent meals, portion control, mindful eating, proper hydration, and exercise, the company claims (and some studies show) you’ll lose between 8 to 13 pounds in the first phase, and an average of 1 to 2 pounds per week. After reading client testimonies posted on the web, we feel these numbers to be fairly accurate of South Beach Diet’s effectiveness.

When you drink liquid carbs, like the sugar in soda, your body doesn't register them the same way as, say, a piece of bread, according to a review of studies published in Current Opinion in Clinical Nutrition & Metabolic Care. That means, even though you're taking in calories, your fullness cues aren't likely to signal that you're satisfied once you finish off a can. And that can lead to consuming more overall.
"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
Popularized by the documentary Forks Over Knives, the Ornish diet is a low-fat, plant-based diet plan based on whole grains, vegetables, fruits, and legumes. It's based on a lacto-ovo style of vegetarianism, allowing only egg whites and nonfat dairy products. It's packed with vitamins, fiber, and lots of filling plants to keep you satiated. Some studies have shown it can reverse heart disease and have beneficial effects on other chronic health conditions. (BTW, there is a difference between a vegan diet and a plant-based diet.)

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)
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.

Even if you suffer from obesity, you don’t have to reach a “normal” BMI (more on this concept later) to reap the benefits that come with shedding some pounds. According to a Center for Disease Control and Prevention study, even a moderate weight loss ranging from 5 to 10 percent of the initial body weight can help you curb and prevent obesity-related illnesses. 
"How easy it is for someone to lose 10 pounds depends on a lot of things: age, gender, activity level, basal metabolic rate, and how much weight he or she has to lose" explains Kate Huether, MD, of The ReKovery MD, who also holds a master's degree in nutrition. "If someone is very overweight it is easier to lose excess weight as opposed to someone who is thinner," Dr. Huether adds.

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.
Make sure that the diet has been studied extensively for safety — and discuss any changes with your physician or registered dietitian before beginning a new diet. (If you don’t have a dietitian, find one in your area at the Academy of Nutrition and Dietetics website.) And do a self-check to ensure the diet fits with your own values and preferences.

The best low-cal diet plan isn't a diet so much as it is a method. CICO stands for "calories in, calories out" and is based on the mathematically sensible principle that as long as you're burning more calories than you're eating, you'll lose weight. All you need to get started is a way to track your calories—there are plenty of apps on the market although a pen and paper works great too—and a food scale to keep you honest about your portion sizes. (Also read this guide on how to safely cut calories to lose weight.) People love the simplicity and straightforwardness of the plan. And while it may not be the fastest way to lose weight, you're guaranteed to have success long term. (Just know that some weight-loss experts actually don't recommend calorie counting.)
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 lb you’re trying to lose.” (32)
If you're not up for crunching numbers every day, you can take a more generalized approach. “For some people, it’s knowing, ‘Typically I eat a whole sandwich,’” says Gagliardi. “Now, I’m going to eat half a sandwich at lunch and save the other half for my dinner and cut my calories in half." To get started, consider these 25 ways to cut 500 calories a day.
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.
Maybe you are trying too many things. If you keep switching diets and are doing too much exercise, your body is trying to balance itself. it might also be caused by lack of sleep or too much stress. Do moderate exercise and start eating a little bit cleaner and the pounds will come off. If you still don't notice a difference, talk to your doctor. You might have a thyroid problem or some other medical issue.

To help you on your way, the WW app allows you to track your food, weight, and activity, look up the Smart Points value of each food, chat live with experts, get over 4,000 recipes, sync your fitness device, scan foods, and find daily inspiration on Connect, a members-only digital community. The app won the 2019 People’s Voice Award Webby for Best Practices thanks to its “advanced practices in app and mobile site development.”
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!"

"When clients come to me, many of them have been through the diet wringer. They've tried every fad and gimmick and, of course, they've failed to maintain long-term success. The key to losing 10 pounds and weight loss, in general, is to never feel like you're on a diet, because diets don't work. If you feel deprived, you will never make it past a few weeks. The only way to achieve long-term weight loss is to learn to appreciate food as fuel and slowly replaced processed food that cannot properly energize the body with real food that can. After a while this will become second nature and won't feel like a daily struggle." — Laura Burak, MS, RD, CDN

After subscribing and placing your order, you’ll receive your weekly meal plan at home in a recyclable package. And, if you live in certain areas, you could also get your food at one of the company’s 200 local pick-up locations. One curious aspect of these locations is that most of them are located in fitness centers, so you can get your sweat on while picking your food. 


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.
Weight loss ultimately comes back to the concept of calories in, calories out: Eat less than you burn and you’ll lose weight. And while it’s possible to lose water weight quickly on a low-carb diet, I certainly wouldn’t advocate for it. The diet itself can trick you into thinking that this eating style is working — when really, you might gain back what you lost as soon as you eat carbs again. That can feel incredibly dispiriting if you want results that last longer than a week.

"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
