Sleep Restriction and Obesity


About this study

Insufficient sleep may be one of the most common, and most preventable, obesity risk factors. The investigators wish to determine whether 14 nights of modest sleep restriction results in increased energy balance, thus potentially increasing the risk of obesity. The investigators hypothesize that sleep restriction will result in increased energy balance.
