About
The goal of this proposed research is to test the hypothesis that long-term mild sleep restriction (SR), as occurs frequently in adults and adolescents, leads to a positive energy balance and weight gain.
Aim 1. To determine the effects of SR, relative to habitual sleep (HS), on food choice and energy intake (EI) in adults at risk of obesity.
Aim 2. To determine the effects of SR, relative to HS, on energy expenditure (EE) via independent and complementary approaches.
Aim 3. To determine whether SR alters body weight and adiposity relative to HS.
Full description
There is an association between short sleep duration (SSD) and obesity. Moreover, short sleepers (<7 hours sleep/night) gain more weight over time than normal sleepers (7-8 hours sleep/night). These relationships are increasingly supported by clinical data showing that restricting sleep duration in healthy, normal weight adults, increases energy intake (EI).
