Obesity among children and adults dramatically increases the risk of chronic illnesses such as heart disease and type 2 diabetes. What are the contributing factors that lead to being overweight? In this seminar, Harvard Medical School doctors and researchers will address the stigma that surrounds obesity and discuss concrete methods, including changes to sleep and diet, that could help scale back this growing problem. Each spring, Harvard Medical School's Office of Communications and External Relations organizes a series of four free "mini-med school" classes for the general public in the heart of Boston's Longwood Medical Area. At the end of the seminar series, participants who attend three out of the four sessions receive a certificate of completion. Topics are selected for their appeal to a lay audience and have included the human genome, nutrition, sleep dynamics and health care access. Faculty from Harvard Medical School and its affiliate hospitals volunteer their time to present these lectures to the community. More »
The 2003 research indicated that exercise is a top weapon against visceral fat, backed up by a 2011 study which found that aerobic exercise is basically a magic bullet. Aerobic exercise is known to most people as cardio — activities such as running and cycling, as opposed to resistance training (where you lift heavy stuff around). While participants in the study worked fairly hard (jogging 20km per week at a high intensity), the researchers said lower-intensity but longer workouts should have similar benefits.
Ultimately, you need to pick a healthy eating plan you can stick to, Stewart says. The benefit of a low-carb approach is that it simply involves learning better food choices—no calorie-counting is necessary. In general, a low-carb way of eating shifts your intake away from problem foods—those high in carbs and sugar and without much fiber, like bread, bagels and sodas—and toward high-fiber or high-protein choices, like vegetables, beans and healthy meats.
A 2012 study also showed that people on a low-carb diet burned 300 more calories a day – while resting! According to one of the Harvard professors behind the study this advantage “would equal the number of calories typically burned in an hour of moderate-intensity physical activity”. Imagine that: an entire bonus hour of exercise every day, without actually exercising. A later, even larger and more carefully conducted study confirmed the effect, with different groups of people on low-carb diets burning an average of between 200 and almost 500 extra calories per day.
Reduced hunger. Many people experience a marked reduction in hunger on a keto diet. This may be caused by an increased ability of the body to be fueled by its fat stores. Many people feel great when they eat just once or twice a day, and may automatically end up doing a form of intermittent fasting. This saves time and money, while also speeding up weight loss.
Some people can't eat grapefruit because it interacts with certain medications. Others just don't care for it. Either way, don't substitute it with oranges or orange juice. Oranges won't give your body the same alkalizing effect that grapefruit produces. In fact, oranges promote more acidic pH balances. The more acidic the pH balance, the easier it is for the body to store fat.
Each person loses weight at a different rate. The best thing you can do is set reasonable goals. If your goal is too lofty, it not be reached leaving you disappointed and ready to give up. Often people contact me, disappointed that they lose between 2-3 pounds per week, then I remind them that a weekly average of 2.5 is 120 pounds lost in a year. Try not to look at the short game, look at the long game, it will keep you motivated.
Choose Liquid Calories Wisely. Sweetened drinks pile on the calories, but don't reduce hunger like solid foods do. Satisfy your thirst with water, sparkling water with citrus, skim or low-fat milk, or small portions of 100% fruit juice. Try a glass of nutritious and low-calorie vegetable juice to hold you over if you get hungry between meals. Be careful of alcohol calories, which add up quickly. If you tend to drink a glass or two of wine or a cocktail on most days, limiting alcohol to the weekends can be a huge calorie saver.
You'd think it makes sense: if you have too much belly fat, do a lot of core work to make it go away. But Sylwia Wiesenberg, founder of Tonique Fitness, says it's counterproductive. "If you have extra belly fat, you'll never see the muscles you're working underneath," she explains. "Instead, focus on building a strong lower body—the largest muscle group, and therefore most calorie burning—which will help keep your metabolism humming long after." Then, when you are ready for abs work, do it standing up. A review of core training by the American College of Sports Medicine found that it's a more effective way to tone than traditional exercises that have you on the floor.
One of the very first cardio exercises to reduce belly fat is walking. Surprised? Do you think it’s too simple to be effective? Well, then you should know that walking is a great and effective way to burn away that ugly belly fat. In fact, it is an excellent fat burner for your entire body. If you follow a healthy diet along with walking at a steady pace for 30-45 minutes for at least four to five days every week, you will witness a gradual decrease in your weight.

Those trans fats on your menu are hiding out in plain sight and sabotaging your lean belly plans every time you eat them. If a food product says it contains partially hydrogenated oils, you’re eating trans fat, which can increase your risk of heart disease, high cholesterol, and obesity with every bite. In fact, research conducted at Wake Forest University reveals that monkeys whose diets contained eight percent trans fat upped their body fat by 7.2 percent over a six-year study, while those who ate monounsaturated fat gained just a fraction of that amount. Instead of letting harmful trans fat take up space on your menu, fill up with the 20 Healthy Fats to Make You Thin.

Before starting, ask yourself what is really realistic for you, Mattinson suggests. Then get your doctor’s okay. You may also work with a local registered dietitian nutritionist to limit potential nutrient deficiencies and talk about vitamin supplementation, as you won’t be eating whole grains, dairy, or fruit, and will eliminate many veggies. “A diet that eliminates entire food groups is a red flag to me. This isn’t something to take lightly or dive into headfirst with no medical supervision,” she says.
Here’s more reason to add avocado to everything. “Most of the carbohydrate content in avocados comes from fiber (1/3 of an avocado provides 11 percent of our daily fiber needs), and it also contains monounsaturated fat, which is known as a ‘good’ fat and [is] important for heart health,” says Zigler. Together, the healthy fats and fiber will keep you full to avoid mindless munching throughout the day.
The popular low-carb diets (such as Atkins or Paleo) modify a true keto diet. But they come with the same risks if you overdo it on fats and proteins and lay off the carbs. So why do people follow the diets? "They're everywhere, and people hear anecdotally that they work," McManus says. Theories about short-term low-carb diet success include lower appetite because fat burns slower than carbs. "But again, we don't know about the long term," she says. "And eating a restrictive diet, no matter what the plan, is difficult to sustain. Once you resume a normal diet, the weight will likely return."
There’s a large spectrum of where people can fall on a vegetarian diet: For example, vegans consume no animal products, whereas ovo-lacto vegetarians eat both dairy and eggs. The eating style may help with weight loss, suggests a review published in August 2017 in Nutrients, but some vegans and vegetarians may become deficient in specific nutrients, such as calcium, iron, zinc, and vitamin B12, according to an article published in December 2017 in Nutrition, Metabolism and Cardiovascular Diseases.

“The alkaline diet often has a focus on eating lots of fresh produce and unprocessed foods, which could be a good thing,” says Hultin. “However, keep in mind that this is not an evidence-based therapeutic diet. When people take it too far — for instance, drinking baking soda — or become too restrictive or obsessive over food choices, it can definitely turn negative.”
3. Doing Bicycles not only help to melt belly fat it also works on the muscles of your upper body. For this you have to lie on your back and raise your legs at 90 degree, then bend your legs to 90 degree and hold it. Keep your hands under your head and slowly raise your head and shoulder off the ground. Now with a fast movement bring your right elbow to your left knee and extend your right leg in the front. You have to switch sides fast to create the cycling effect. Use your core muscles to keep your head and shoulder above the ground throughout the exercise. Do 20 repetitions and add 10 as you become stronger.
Being seriously committed to this type of eating, I've found it helpful to have a ketone blood tester to check on where I'm at, at different points. The breath and urine testers are a waste of money if you want accurate testing. The tester I found, and believe is the most accurate and least expensive is called Keto Mojo. It tests both ketones and glucose and if you purchase it from them, you're guaranteed to be able to purchase ketone test strips for only .99 cents, instead of the $2.00 to $7.00 each, as I've seen them listed for on the internet.
If you want to shrink your gut, get enough protein in your diet. In this case, about 25 percent of calories. Why? For starters, protein makes you feel full and helps you build muscle (which increases metabolism, thereby making it easier to lose weight). Just as important, high-protein diets have been shown to be the best way of attacking belly fat. In one study, published in the International Journal of Obesity, Danish researchers put 65 people on either a 12 percent protein diet or a 25 percent protein diet. The low-protein dieters lost an average of 11 pounds, which isn't bad. But the high-protein subjects lost an average of 20 pounds--including twice as much abdominal fat as the low-protein group.
In a recent study in the Journal of Sports Medicine and Physical Fitness, Weiss and his colleagues found that participants performed worse on high-intensity cycling and running tasks after four days on a ketogenic diet, compared to those who’d spent four days on a high-carb diet. Weiss says that the body is in a more acidic state when it’s in ketosis, which may limit its ability to perform at peak levels.

Want to lose that belly fat? In your dreams! Seriously, though: a good night’s sleep is one of the best ways to get rid of that extra fat around your waist for good. Among the 60,000 women participating in the Nurses’ Health Study, those who snoozed for fewer than five hours a night were at the greatest risk of becoming obese and gaining 30 or more pounds over the course of the 16-year study period when compared to those who slept for seven or more hours.
3. Tabata: Tabata is another form of interval training and involves 8 rounds of 20 seconds exercise followed by 10 seconds rest. Sounds easy enough but exercise should be done at a high intensity. This exercise can be done using rowing machines, dumbbells or thrusters. This is a tough exercise and is best for those who have very less time in their hands.
Many people claim success with this diet, but nutrition experts caution against following the plan for a long-term period. Starvation or fasting diets have been debated often, and support is still anecdotal. While this diet may meet your initial weight loss goals, it's not a long-term, sustainable lifestyle (the website itself says that it's about quick fixes and providing support in a weight loss emergency).
The Scottish military surgeon, John Rollo, published Notes of a Diabetic Case in 1797. It described the benefits of a meat diet for those suffering from diabetes, basing this recommendation on Matthew Dobson's discovery of glycosuria in diabetes mellitus.[11] By means of Dobson's testing procedure (for glucose in the urine) Rollo worked out a diet that had success for what is now called type 2 diabetes.[12]
Swanson, a professor of neurology who has researched the impacts of ketogenic diets on inflammation in the brain, got curious about the ketogenic diet when trying to treat the inflammation that persists for days after a person suffers a stroke. When he tried inducing a ketogenic state in mice with stroke injuries, he said, “I was overwhelmed by the effect.” Blocking glucose metabolism worked to suppress inflammatory genes, which in turn helped stroke healing.
By now, you probably know that coffee can help curb your appetite. But did you also know it can boost your metabolism? Since coffee contains the antioxidant chlorogenic acid (CGA), it can actually increase your body’s use of fat for energy. Research has additionally shown that CGA can slow the release of glucose and lower insulin resistance to inhibit weight gain after eating a meal.

On the face of it, skipping meals seems like a path to losing weight — if you don’t eat as much, you’ll drop fat. But in practise, it doesn’t work out like that. A 2015 study from Ohio State University found that skipping meals messes up your metabolism and your hormones (specifically insulin), which results in an increased likelihood of abdominal weight gain. Researchers recommended eating several small meals throughout the day as opposed to one or two big ones.


A: The amount of weight you lose is entirely dependent on you. Obviously adding exercise to your regimen will speed up your weight loss. Cutting out things that are common “stall” causes is also a good thing. Artificial sweeteners, dairy, wheat products and by-products (wheat gluten, wheat flours, and anything with an identifiable wheat product in it).
Belly fat is is different from fat elsewhere in your body. The extra weight some people carry around their waists, arms, and love handles isn’t the same — that’s subcutaneous fat, which sits beneath the skin and is relatively harmless, according to Harvard Medical School. The stuff in your belly, visceral fat, lodges deeper down, around your abdominal organs. It's metabolically active tissue that actually functions like a separate organ, releasing substances into the rest of your body that, in excess, can increase your risk of disease.

Cancer, a very common and sometimes fatal cause of unexplained (idiopathic) weight loss. About one-third of unintentional weight loss cases are secondary to malignancy. Cancers to suspect in patients with unexplained weight loss include gastrointestinal, prostate, hepatobiliary (hepatocellular carcinoma, pancreatic cancer), ovarian, hematologic or lung malignancies.
