A series of studies are proposed to develop an intervention to increase sleep duration and study the effects on eating, exercise, and weight control. The hypothesis is that increasing sleep duration will help improve weight loss and maintenance.
Study 1 is conducted in a sleep laboratory. Participants sleep short duration (approximately four hours per night) on one weekend and long duration (approximately nine hours per night) on another weekend. Study 2 is examining ways to increase sleep duration in overweight individuals with short sleep and examining the effects on short term weight loss. Study 3 is comparing a standard weight loss program with a novel Sleep+Weight Loss intervention.

Sleep Duration
Participants with verified short sleep are taught to increase their sleep either gradually or immediately. These two groups are compared to a control group who makes no changes in their sleep. The primary outcome is sleep duration per night as determined by actigraphy.
Time frame: 4 weeks
Eating Behavior
24-hour recalls are used to estimate dietary intake at baseline and after 4 weeks of sleep intervention.
Time frame: 4 weeks
Physical Activity
Objective measures of physical activity are obtained before and after the 4-week sleep intervention.
Time frame: 4 weeks
