Schematic of the experimental protocol (A) and food intake data during habitual (H) or sleep restriction (SR) (B). The volunteers participated in a 4 day inpatient study where diet, sleep and food intake were controlled. Serial sampling of plasma occurred on day 4. Fasting samples were collected on morning of day 5 prior to individuals given the opportunity of food selection (Pre-FS) and on day 6 (Post-FS). The impact of sleep was assessed using a randomized crossover design; in the following panels short sleep data is shown with open symbols while habitual sleep data is shown with grey-shaded symbols. Also shown are the intakes of energy in the form of protein, carbohydrates or fat expressed as kcal (B) during habitual and sleep deprivation.
