Among the perils of a new school and entirely new environment lies the myth – or is it? – of the Freshman 15, those 15 or more extra pounds gained during the freshman year. Many factors cause weight gain in college – heavy drinking, all-you-can-eat dining plans, late-night binges, no more high school sports and a lack of Mom’s wholesome cooking all contribute. The situation isn’t as dire as imagined; a 2008 study found that female college students gained an average of only 7 pounds. But any weight gain can be unhealthy. So how can students give healthy living the old college try? Changing dining-hall and frat-house habits seem to be the best way. Students should try to eschew gorging themselves at the buffet. Stash a few pieces of whole fruit from the cafeteria for late-night snacks, instead of ordering that pizza at 2 a.m. Fill that bottomless plate with fresh greens and vegetables, and be sure to ask the staff how certain foods are prepared. Plenty of sleep is important for anyone trying to stick to a diet and exercise program, so limiting the late-night partying or cramming is important for students who want to avoid weight gain. Binge drinking is a harmful habit prevalent on many campuses. Alcohol consumption not only causes weight gain, but also puts students in dangerous situations. If you must drink, reduce your consumption. Try alternating glasses of water in between glasses of booze. And take heart – most students see their weight cycle back to pre-college numbers in their junior and senior years.
