A new study of 1,800 pairs of twins found that even if you're genetically predisposed to being overweight, there is one easy thing you can do to put yourself in control of how much weight you gain.

 As reported by CNN, researchers found that genes accounted for 70 percent of the differences in body mass index (BMI) in those who slept less than seven hours per night. Environmental factors, such as diet and exercise, accounted for just four percent of the differences. But in twins who slept nine or more hours per night, environmental factors shot up to 51 percent, and genetic influences dipped to 32 percent. So, sleep deprivation appears to have a significant influence over your genetic expression.

 According to CNN Health1:
