...mainly shown that very high doses of alcohol given to adolescent rats (those roughly 40 days old) affect those animals differently from the way alcohol affects adult rats. In typical studies, the rats are injected with 5 g of alcohol per 1,000 g of their body weight, often after the rodents have been deprived of food for 12 hours. Rats metabolize alcohol about 10 times as fast as humans, but in a typical rat, this 5 g/kg dose on an empty stomach still results in a monumentally high blood-alcohol concentration. "It's difficult to compare to humans...
...does not eliminate heart risks faced by heavy women. Assessing nearly 39,000 middle-aged women over a period of 11 years, researchers determined that the odds for developing heart disease were 54% higher in overweight active women and 87% higher in obese active women compared with normal-weight active women. Women who were normal weight but inactive faced only an 8% increase in risk. "If you're overweight or obese, you can't really get back to that lower risk entirely with physical activity alone," says lead author Dr. Amy Weinstein of Boston's Beth Israel Deaconess Medical Center...
...report, published last year in the New England Journal of Medicine, went further, comparing the medical records of 276,835 Danish citizens born between 1930 and 1976. In that data, scientists found a direct and linear correlation between a higher childhood weight and a greater chance of future heart disease. "Our study shows that even a few excess pounds can damage future health," says co-author Dr. Jennifer Baker of the Center for Health and Society at the Institute of Preventive Medicine in Copenhagen...

After gaining nearly 50 lb. following knee surgery, she could not lose the weight with exercise alone. So she turned to a longtime love, dancing. "Riding the elliptical just couldn't motivate me enough," she says. "Dancing was a way to trick myself into being active." Shortly after, Stroh answered a casting call for High School Musical, scoring her part over dozens of other actors. "I am not a size 2, never will be," she says. "I can just...
