To Stay Slim, Try Nuts, Wine, Sleep New studies address weight issues By Matt Cantor, Newser User Posted Apr 13, 2012 12:14 PM CDT Updated Apr 15, 2012 2:23 PM CDT 21 comments Comments Nuts may help fight obesity. (Shutterstock) (Newser) – A wealth of findings offer some new tips to keep off the pounds. Looks like tree nuts, red wine, and plenty of sleep can all help you stay fit. Researchers found that nut eaters weighed less and had a lower waist circumference and BMI than those who don't eat nuts, the Daily Mail reports. The snacks may also help fight heart disease. Meanwhile, scientists have spotted a compound in red wine that battles obesity by slowing the growth of fat cells. The compound, piceatannol, may also fight neurodegenerative diseases and cancer, the Mail notes. Sleep habits can also have an effect on your weight: Research subjects who got less than five and a half hours burned some 120 fewer calories a day, leading to a 12.5 pound weight gain over a year. (Another study finds that those who sleep less also consume more calories.) Lastly, some news for diet soda fanatics: What you eat is apparently more important than what you drink. Some 32% of diet soda drinkers who ate a "Western" diet of meats, fried food, and sugars developed metabolic syndrome over two decades, compared to 20% of diet soda fans who ate a "prudent" diet of fruits and veggies, fish, and whole grains. The lowest risk, at 17.8%? Those who followed a "prudent" diet and drank no soda, NPR reports.
