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)


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)
“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.”
"When you're stressed out or tired, it's very easy to forget when your hand goes into the cookie jar," says Marisa Sherry, RD, a registered dietitian in private practice in New York City. "Are you being honest with yourself about taking just one handful here and there? When you have a cup, are you really having one cup? Most drinking glasses hold about three cups. By the end of the day, it all adds up."

Speaking of intervals, high-intensity interval training (otherwise known as HIIT) has been shown to be incredibly effective for weight loss. Because the workouts are so intense, you don't need to put in an hour — or even 30 minutes — at the gym. According to the American College of Sports Medicine, seven minutes is all you need to get in the best shape of your life.
The best way to lose weight on the Bulletproof Diet is with Bulletproof Intermittent Fasting.  But if waiting for results just isn’t your thing, you can use this Bulletproof Rapid Fat Loss Protocol – but only if you are currently significantly overweight or obese, and you have healthy, functioning kidneys and liver.  However, you need to understand that your body stores toxins in fat that your liver couldn’t excrete, so when you lose weight very rapidly, those toxins are released and can make you very sick.  This Bulletproof Rapid Fat Loss Protocol helps you avoid any side effects from this toxin release, so it’s important to follow the plan carefully.

Lifestyle fit: Figure out whether a plan is compatible with your lifestyle before committing. Some meal plans are very simple; others require more work. Think about how much time and planning goes into each weight loss program. Some people find that meal planning and preparation takes up too much time, while others enjoy planning meals and spending time in the kitchen. 

There are hundreds of healthy living apps that can help you lose weight. Find one that aligns with your goal, whether it's to get stronger, get faster, get off the couch, or eat healthy. Cyr found that using MyFitnessPal helped her get a better grip on what she was eating every day. "Once I started logging my meals, I realized I was scarfing 1,700 calories a day," she says. 


The HMR Program uses meal replacements – think low-calorie shakes, meals, nutrition bars and hot cereal – in phases, coaching from experts, physical activity and an emphasis on fruits and vegetables to help dieters shed pounds fast. While last year the diet shared the No. 1 ranking in this category with the Biggest Loser diet, this year it has the top spot to itself. "This diet makes it easy to lose weight fast and would likely be effective for someone who wants to lose weight for a specific event," one expert said. "However, as far as long-term healthy-habit-forming, this diet falls short" in part because dieters don't learn to make their own healthy food choices.

Ask any diet expert what they think about fiber, and they’re bound to tell you it’s an imperative part of any fat-loss plan. “According to research from Wake Forest Baptist Medical Center, eating foods rich in soluble fiber, like oatmeal (one of the Best Carbs for Weight Loss), apples and beans, can reduce belly fat, says McDaniel. Weight management specialist Sarah Koszyk, who’s also a big proponent of eating fiber for fat loss, suggests eating berries. ““Berries like blueberries and raspberries are packed with fiber, low in sugar and calories, and chock-full of vitamins,” she says.”
The final possible culprit behind stubborn weight issues may be the stress hormone, cortisol. Too much cortisol will increase hunger levels, bringing along subsequent weight gain. The most common cause of elevated cortisol is chronic stress and lack of sleep (see tip #10), or cortisone medication (tip #9). It’s a good idea to try your best to do something about this.
Support your weight loss and exercise program by getting between 1.2 and 1.6 grams of protein per kilogram (or 0.55 and 0.73 grams per pound) of your body weight, recommends research published in the American Journal of Clinical Nutrition in 2013. For a 200-pound woman, this would suggest you aim for 110 to 146 grams of protein daily, split up among three to five meals.
I just bought your 30 day fat loss plan. I was browsing through your website, and found the Wild Diet rapid fat loss protocol. I’m completely lost now reading to eat less fat to lose fat. I’m use to do intermittent fasting, and want to carry on doing. I was following the Bulletproof diet, which is great, but sometimes it would take me 5 days to lose a pound. I’m so impressed with Kurt’s result that I would like to try your method. I’m moving abroad in 2 months time, and really would like to loose quite a bit of wait while here in the U.S
If you’re going out to dinner or drinks over the weekend, you usually know ahead of time, which is good news for your waistline. This allows you to plan ahead and make smart diet decisions throughout the week. “One meal won’t kill your goals but being consistently inconsistent will. Get constant with good habits and plan ahead if you’re going to cheat,” says Kelvin Gary, founder of New York City’s Body Space Fitness.

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.

Loads of research demonstrates people who log everything they eat — especially those who log while they're eating — are more likely to lose weight and keep it off for the long-haul. Start tracking on an app like MyFitnessPal when the pounds start sneaking up on you. It'll help you stay accountable for what you've eaten. Plus, you can easily identify some other areas of your daily eats that could use a little improvement when it's written out in front of you.

For those just starting out on their weight-loss journey, Rachael Lenzmeier Jencks, 43, wants you to know that cutting calories blindly, without thinking about the nutritional impact of the foods you're eating, isn't the answer. "The one thing that I would tell myself is that skipping fruit and veggies to save calories isn't EVER going to do the trick," she says. "What you put in your body does matter and no amount of exercise can undo a bad diet." (Need a little inspo? Check out the best pre- and post-workout snacks for every workout.)
Interval Training: A great way to incorporate high-intensity training without doing it continuously is by doing intervals. Alternate a hard segment (e.g., running at a fast pace for 30 to 60 seconds) with a recovery segment (e.g., walking for one to two minutes). Repeat this series for the length of the workout, usually around 20 to 30 minutes. A 30-60-90 interval workout is a good example of this kind of high-intensity workout.
Weight loss once again came in first place for New Year’s Resolutions, sharing its spot with “becoming a better person.” For a lot of us, becoming a better person starts with feeling better about ourselves. The start of a new year may be primetime to renew dedication to health and happiness, but periodic sprints of weight loss do not equate to wellness. That’s why the best diet is the one you can sustain for the rest of your life.
It works in three different phases. The first phase takes two weeks and helps you eliminate cravings for starches, carbs and sugars by removing them from your diet. It replaces these foods with plenty of lean proteins and low-fat dairy foods. Phase 2 allows you to reintroduce some foods previously prohibited back into your diet with the intention of having better control over your eating habits. You stay in this phase until you reach your weight goal. Phase 3 allows you to eat all types of food in moderation; this should become the healthy lifestyle you will live by from now on. To make food choices simpler, this program delivers meals directly to your door. While this means very little food preparation is required, it also makes this one of the most expensive dieting services on the market. Unfortunately, there is no food substitution guide. To keep you on track, you can contact nutritionists weekly to ask questions and receive tips. Our own tester was able to lose 10 percent of her body weight within two weeks using this program. The biggest downside to her experience was not being able to access progress reporting through the company.
The best way to lower your cortisol levels is by decreasing stress. While it’s easier said than done, weight loss tips like this one involve you simply taking the time to put yourself and your health first. Practicing saying “no” to events and things you know will cause you stress, carve out time to exercise, set aside some time daily — even just 5 minutes — to meditate or practice gratitude and learn to recognize when you’re feeling extra worn out and need a time out.

○ To reduce the stomach, it is not right to make the whole vegetable because the substance of some important ingredient in the meat is also meat. The use of chicken and fish will be more suitable. Fresh vegetables and fruits use vegetable and fruit to benefit from the entire body, so make vegetable and fruit of each season part of your diet, the vitamins, minerals and anti-oxygen contained in them are dieting with you. The lack of food and staying away from healthy foods will be smart.
Also some research shows that the human body is primed to consume most of its calories during daylight hours. But the lifestyle is problematic for many: Because family meals and dinners with friends often are scheduled for after sunset, "people who try to stop eating after 7pm can’t do it every day for the rest of their lives," says Dr. Seltzer, who supports an alternative strategy: Eating a hearty meal at your regular dinnertime.

Believe it or not, sleeping, dieting and training are equally important when it comes to sculpting a sick set of abs. No matter how many calories you cut or miles you log, it won’t get you anywhere near your goal unless you’re also getting enough sleep. In fact, losing a mere hour of shut-eye over the course of three days has been shown to negatively impact the body’s hunger hormone, ghrelin, increasing the number of calories you’re bound to consume each day. Researchers also say that skimping on sleep increases the odds you’ll wind up munching on junk food, especially at night, which can make it difficult to get chiseled abs. Conversely, quality sleep fuels the production of fat-burning hormones that can help you get you that washboard stomach you’ve been working for.
Due to a lack of supporting research, it's too soon to recommend alternative medicine as the primary method to lose weight. Supplements haven't been tested for safety and due to the fact that dietary supplements are largely unregulated, the content of some products may differ from what is specified on the product label. Also keep in mind that the safety of supplements in pregnant women, nursing mothers, children, and those with medical conditions or who are taking medications has not been established. You can get tips on using supplements, but if you're considering the use of alternative medicine, talk with your primary care provider first. Self-treating a condition and avoiding or delaying standard care may have serious consequences.
It may seem like a no-brainer that regular exercise can help you burn fat and lose weight. But it's not just about the calories you're burning. It's also about the adaptations your body makes when you exercise on a regular basis. Many of those adaptations lead directly to your ability to burn more fat without even trying. When you exercise regularly:
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).

The fat on this program makes you feel MUCH better than you do on a fast or a low fat diet. Most people can continue to work (in office jobs) at normal levels. In fact, most people feel like rock stars, with even more energy than normal. This is not a diet to use while you’re working out excessively, although a short workout once a week right before you eat will help.

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.)


Regardless of where you stand, the fact is that the Paleo way of eating is becoming increasingly popular, as are "nutritional reset" programs based upon Paleo, such as the Primal Blueprint 21-day Challenge hosted by Marks Daily Apple, or the Whole30 program, popularized by the New York Times bestseller, It Starts with Food: Discover the Whole30 and Change Your Life in Unexpected Ways (Est. $15).

Basically every diet that we cover in this report is low carb to some extent in that they discourage processed foods and foods made from white flour, and most assign higher caloric/points values even to foods that contain whole grains than to other types of food. However, many experts are leery of any diet that eliminates entire food groups -- in this case grains and many starches. However, plenty of others point out that vegetarians and vegans do not receive this type of criticism even though those diets also eliminate several food groups.

Walnuts, soybeans, flaxseeds, and almonds are four of the best choices to help melt away stubborn belly fat.  Just remember that nuts are also very high in calories.  Be sure to limit yourself to the recommended serving size – usually a small handful – of these foods so you can reap the health benefits without accidentally sabotaging your weight-loss efforts.
If you’re logging just a few hours of sleep a night, you may actually find yourself gaining weight. Researchers at the University of Chicago Medical Center found that subjects who slept just four hours had a harder time processing carbs. "When you're exhausted, your body lacks the energy to do its normal day-to-day functions, which includes burning calories efficiently," says Talbott.
You know you're supposed to eat more protein to lose weight, but you might not know exactly why. Well, it actually has to do with how your body handles insulin. "Your body starts to produce more insulin as you age, since your muscle and fat cells aren't responding to it properly," explains Louis Aronne, M.D., director of the obesity clinic at Cornell University.
It’s natural! It’s packed with Vitamin C! It comes from Florida! What could be wrong? Well, although 100 percent fruit juice is a better pick than sugary drinks like Sunny D, even the all-natural stuff still packs up to 36 grams of sugar per cup—or about what you’d get from popping 4 Krispy Kreme glazed donuts into a blender and hitting frappé. What’s more, most of the sweetness in juice comes from fructose, a type of sugar associated with the development of visceral adipose tissue—yep, that’s belly fat.

Green tea isn't known only for its cancer-fighting benefits: It may help boost your metabolism, too. People who took green-tea extract three times a day saw their metabolic rate increase by about 4 percent, according to a study published in the American Journal of Clinical Nutrition. (Translation: You could burn an extra 60 calories a day, which equals about six pounds a year!) It may be because green tea contains catechins, which increase levels of the metabolism-speeding brain chemical norepinephrine, says Joy Bauer, a New York City nutritionist and author of Cooking with Joy.
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.
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?
Gastrointestinal disorders are another common cause of unexplained weight loss – in fact they are the most common non-cancerous cause of idiopathic weight loss.[citation needed] Possible gastrointestinal etiologies of unexplained weight loss include: celiac disease, peptic ulcer disease, inflammatory bowel disease (crohn's disease and ulcerative colitis), pancreatitis, gastritis, diarrhea and many other GI conditions.
There is always a lot of controversy when it comes to evaluating diets. Many people are firmly in one camp or another over the "right" way to eat. Studies are often contradictory in their findings, and many critics charge that government recommendations are influenced by the food industry. We present the controversies and cross-opinions, when relevant, but we do not take sides; in our opinion the best diet is the one you feel best on and can stick with.

Having support is very important with weight loss. If everyone can get on board, it will be easier to achieve your goals. Talk to your family (or friends, roommates, etc) before starting your diet and let them know your plan. Explain why you are making this decision and ways they can help you succeed. Even if they do not change with you, that's okay! Go forward with your plan! They may decide to join you once they see you succeed with weight loss.
“A lot of people think the foundation of a paleo diet is high-fat meat, but I suggest that it’s vegetables,” says Hultin. The concept is to eat only foods — including meat, fish, poultry, eggs, fruits, and vegetables — that would have been available to our Paleolithic ancestors. This means grains, dairy, legumes, added sugar, and salt are all no-no’s.
It takes more than just crunches! We start to gain weight in our midsection when our cortisol levels spike. Stress is one of the primary culprits for high levels of cortisol secretion. When this happens cortisol breaks downs lean muscle (the type of tissue that burns calories most efficiently) and also holds on to fat storage in the abdominal region. That stress can even get WORSE with bad dieting; studies show that the stress caused by dieting can increase cortisol levels, making no change in belly fat even with calorie restriction. So how do you shape up? Incorporate these 6 things below and you will be on your way to a flatter belly in no time flat!

Unsurprisingly, the results showed that nothing had happened to the weight of the women receiving calcium or the placebo. However, the group which took the multivitamin lost more weight – about 3 kg more – and improved their health markers. Among other things, their basal metabolic rate (the rate at which the body burns calories when at rest) increased.
Make sure that everything you're eating is whole — as in nothing processed or packaged. Since salt is a preservative, these are the foods that are highest in sodium — something to keep in mind when planning your meals. Plan on making sure that all items you choose are fresh. That means filling up on fresh fruits and veggies, whole grains, low-fat dairy, and lean protein.
I built this protocol for people who simply won’t take my advice to be patient and eat the Bulletproof Diet while using Bulletproof Intermittent Fasting. It uses biohacking techniques I pioneered on myself to reduce – but not eliminate – the risks of rapid fat loss. It prevents the metabolic harm and brain fog that come with very low-calorie diets (or multiple day fasts), and it does everything I can think of to maintain health in the face of additional toxins.  This is also not intended for people who are already fairly lean (10-14% body fat).  It is designed for obese and severely overweight people who want to lose fat as fast as possible.

“One of the best ways to build endurance, strength and burn fat during a workout is through high-intensity treadmill power training,” says Jimmy Minardi of Minardi Training. Here’s how: Start the treadmill speed at a slow jog, and once you’re warm, gradually increase the incline to 15%, keeping the speed the same, explains Minardi. After 45 seconds at 15%, start lowering the treadmill and continue to run until it’s completely flat. Do five intervals with a 3 to 5 minute rest in between each, or until your heart rate has returned to normal.
Salt, in moderation, is a good thing—the mineral is necessary for a healthy heart and brain. But too much salt and you’ll retain water, bloating up like a water balloon. Cutting salt is one of the primary ways to drop extra water weight (one reason you may see a big weight loss when starting a new diet!). Move the salt shaker off your table so you’ll get out of the habit of routinely salting all your food. Then if you taste your food and still really want salt you can still stand up and get some. For more weight loss benefits, add these fat-burning foods to your plate to help you lose weight.
