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 »
“Thirst and hunger cues feel similar, so it’s important to stay hydrated, especially if you’re trying to lose weight,” explains Moon. Yes, plain water is important, but 20 percent of our daily water intake comes from foods, she says. “Watermelon is 92 percent water, plus it is bursting with vitamins A and C and anti-inflammatory nutrients like lycopene,” she explains.
During the 1920s and 1930s, when the only anticonvulsant drugs were the sedative bromides (discovered 1857) and phenobarbital (1912), the ketogenic diet was widely used and studied. This changed in 1938 when H. Houston Merritt, Jr. and Tracy Putnam discovered phenytoin (Dilantin), and the focus of research shifted to discovering new drugs. With the introduction of sodium valproate in the 1970s, drugs were available to neurologists that were effective across a broad range of epileptic syndromes and seizure types. The use of the ketogenic diet, by this time restricted to difficult cases such as Lennox–Gastaut syndrome, declined further.
According to Paquette, the Military Diet does have one advantage over other weight loss plans: unlike other diets like Keto, which tend to eliminate entire food groups, the military diet includes a mix of protein, carbohydrates, and fats, albeit in tiny amounts. But he says the guidelines for the diet are simply too general to be considered healthy. For instance, breakfast on the first day simply lists "toast," without specifying whether it's whole-wheat or white.
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).
Con: Results can vary depending on how much fluid you drink. By drinking more water, you dilute the concentration of ketones in the urine and thus a lower level of ketones will be detected on the strips. The strips don’t show a precise ketone level. Finally, and most importantly, as you become increasingly keto-adapted and your body reabsorbs ketones from the urine, urine strips may become unreliable, even if you’re in ketosis.
It's so easy to run through the store and grab products blasted with "healthy," "all-natural," "organic,""vegan," or "gluten-free" all over them. But Ilyse Schapiro, M.S., R.D., and Hallie Rich, authors of Should I Scoop Out My Bagel, say that's exactly what could be making the belly bulge stick. "You still must read the nutrition labels because many of these foods can be high in sugar, calories, carbohydrates, and processed ingredients in order to make up for the lack of flavor," says Schapiro. And unlike the nutrition labels, front-of-the-box packaging is not tightly regulated and monitored. Because it's what you see when you walk down the aisle, research shows that it gives people a "false sense of health" and they fail to understand what leads to obesity and what doesn't. A few tricks to keep in mind: multigrain bread doesn't mean it's 100-percent whole-wheat, and anything "no-sugar-added" is loaded with simple sugars or complex starches that pack on those sneaky pounds.
A diet that’s low in fat and carbohydrates can improve artery function, according to a 2012 study by Johns Hopkins researchers. After six months, those on the low-carb diet had lost more weight, and at a faster pace. But in both groups, when weight was lost—and especially when belly fat shrank—the arteries were able to expand better, allowing blood to travel more freely. The study shows that you don’t have to cut out all dietary fat to shrink belly fat. For heart health, simply losing weight and exercising seems to be key.

According to Mike Russell, MD: "If you weigh 180 pounds and your goal weight is 130 pounds, losing 20 pounds in one week—the right way—teeters on the brink of impossible. If you’re more like a Biggest Loser contestant, weighing 380 pounds, then losing 20 pounds in one week is plausible (especially considering a large amount of water weight you would lose during the first week)."
1. Bicycle Crunches are a great ab exercise and work the abs from every angle. It’s a combination of the regular crunch, a side-to-side motion that hits the oblique muscles and a reverse crunch that targets the lower abs. You can change the difficulty level by increasing or decreasing the range of motion used and the speed of movement as well as the intensity of the crunch by holding and squeezing.
Low-fat diets involve the reduction of the percentage of fat in one's diet. Calorie consumption is reduced because less fat is consumed. Diets of this type include NCEP Step I and II. A meta-analysis of 16 trials of 2–12 months' duration found that low-fat diets (without intentional restriction of caloric intake) resulted in average weight loss of 3.2 kg (7.1 lb) over habitual eating.
While it’s often assumed that bread is off-limits when you’re trying to lose belly fat, the right bread may actually expedite the process. Switching to sprouted bread can help out carb-lovers eager to get their fix without going up a belt size, thanks to the inulin content of sprouted grains. The results of a study published in Nutrition & Metabolism reveal that found that pre-diabetic study subjects whose diets were supplemented with inulin shaved off more belly fat and total weight than those whose meal plans didn’t pack this healthy prebiotic fiber.

Ranging from just-juice to just-tea cleanses, these typically short-term plans can be dangerous. “Detoxes and cleanses are usually low in calories, protein, and fiber, all nutrients that our bodies need to function,” says Alissa Rumsey, RD, who is in private practice in New York City. “These plans leave you feeling hungry and cranky, causing a rebound food binge once you stop the detox.”
Josh Axe, a doctor of natural medicine and clinical nutritionist, estimates that about 25% of people who try a ketogenic diet experience these symptoms, with fatigue being the most common. “That happens because your body runs out of sugar to burn for energy, and it has to start using fat,” he says. “That transition alone is enough to make your body feel tired for a few days.”
In 2008 between US$33 billion and $55 billion was spent annually in the US on weight-loss products and services, including medical procedures and pharmaceuticals, with weight-loss centers taking between 6 and 12 percent of total annual expenditure. Over $1.6 billion a year was spent on weight-loss supplements. About 70 percent of Americans' dieting attempts are of a self-help nature.
