The Freshman 15 is no myth, and it turns out the changes in body composition over college tend to be pretty drastic. A new study followed more than 100 college students, and found that nearly three-quarters had gained weight by the time they graduated. The percentage who were overweight increased, too—from 18 to 31 percent!

Of course, college isn’t the only time that other aspects of life can get in the way of healthy living, so keep your eye on the prize, no matter what your age!
