In a study of 91 teenagers, 54 of whom were categorized as "obese" according to the body mass index, researchers determined that obesity was related to the size of a brain region implicated in impulsive behavior and self-monitoring. Those regions were relatively bigger among leaner teenagers, and smaller in obese study participants. All the study participants were given questionnaires on their ...
(Oct. 27) -- For years, nutritionists and industry officials alike have considered the merits of high-fructose corn syrup with one key fact in mind: At a chemical level, it has nearly equal levels of fructose and glucose. As it turns out, that may not be true after all. A new study published in the journal Obesity measured the amounts of different types of sugars in 23 kinds of drinks sweetened with high-fructose corn syrup. And they found that several brands contained corn syrup made up of 65 percent fructose, not 55 percent, which has been the commonly cited statistic until now. The ...
(Oct. 12) -- Dick Cheney is back in the public eye, after months of recovery following major heart surgery in July. But there's now much less of Cheney to look at, as the former vice president has shed a reported 20 pounds from his frame. And that weight loss is accompanied by a disconcerting frailty, according to onlookers who watched Cheney partake in a Q&A at the Bakersfield Business Conference in California. Felix Adamo, The Bakersfield Californian / ZUMA Press A frail-looking Dick Cheney holds on to a chair as he takes the stage at the Bakersfield Business Conference on Saturday in ...
(Oct. 11) -- Nutritious food and adequate exercise can't entirely trump genetics where weight -- and where it ends up on your body -- is concerned. It's a reality that researchers have known for years, but one that's been reinforced by a new discovery of over 30 different genetic variations implicated in body composition and shape. What Are the Latest Findings? In a study published in Nature Genetics, an international team composed of 400 scientists runs down variations in DNA sequences that are tied to body weight. Some of the sequences seem to affect one's vulnerability to weight gain. ...
(Oct. 5) -- Logging adequate sleep might be a key component of losing unneeded fat, rather than valuable lean body mass. A small study on 10 overweight or obese adults, published in this week's Annals of Internal Medicine, suggests that diet and exercise are only part of the solution in attaining a healthy body mass and composition. Study participants were sequestered to a controlled environment for four weeks, with their meals, exercise routines and sleep schedules strictly monitored. Because self-reporting is often skewed, the approach makes the research all the more intriguing. Longer ...
(July 21) -- Some squirrels are getting a lot plumper than they used to be, but the root cause of their weight gain isn't what you might suspect (not saturated-fatty nuts, sorry!): It's global warming. That's the conclusion drawn in a three-decade-long study on the yellow-bellied marmots -- large ground squirrels also known as rock chucks -- that inhabit the Upper East River Valley in Colorado, the results of which are in the latest issue of the journal Nature. It's reportedly the first time that climate change has been linked to physical changes in an animal population. A yellow-bellied ...
(July 14) -- Bad news for older women: Carrying a extra few pounds could mean something a lot worse than unflattering clothes. According to experts at Northwestern University, it could mean memory problems too. In a study published today in the Journal of the American Geriatric Society, researchers took a group of 8,745 women aged 65-79 and gave them a 100-point memory test. The results showed that for every one-point increase in a woman's body mass index (BMI), her memory score dropped one point. Northwestern University This illustration shows the difference between women's body shapes ...
Clothes look good on thin bodies. But thin bodies naked? Not so much. Naked full bodies is another matter. Or near-naked, a la actress Christina Hendricks in a corset on the cover of New York Magazine. Hendricks, a breakout star of AMC's hit show "Mad Men," is undeniably beautiful. She's also a different body type than we're used to seeing in the glamor factories of Los Angeles and New York. But then "Mad Men" is a period drama, set half a century ago. It may be relevant that most fashion designers are gay men. Thin women look more male than their voluptuous counterparts in the general ...
(Feb. 9) -- It's easy to see why Michelle Obama has launched a campaign to prevent America's children from putting on too much weight. Just look around the nation's schools and malls. Or, more to point of the first lady's Let's Move program, look at the kids sitting motionless in the glow of video screens from coast to coast. The chart below illustrates the dramatic increase in childhood obesity during the past three decades. Statistics collected by the Centers for Disease Control and Prevention from a variety of studies over the years show the percentage of school-age children (6-19) ...
