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.
