Sleep restriction leads to increased activation of brain regions sensitive to food stimuli.

ABSTRACT:

Background

Epidemiologic evidence shows an increase in obesity concurrent with a reduction in average sleep duration among Americans. Although clinical studies propose that restricted sleep affects hormones related to appetite, neuronal activity in response to food stimuli after restricted and habitual sleep has not been investigated.

Objective

The objective of this study was to determine the effects of partial sleep restriction on neuronal activation in response to food stimuli.

Design

Thirty healthy, normal-weight [BMI (in kg/m²): 22-26] men and women were recruited (26 completed) to participate in a 2-phase inpatient crossover study in which they spent either 4 h/night (restricted sleep) or 9 h/night (habitual sleep) in bed. Each phase lasted 6 d, and functional ma
