They were instructed to purchase as much as they could out of a possible 40 items, including 20 high‐caloric foods (>2 kcal/g) and 20 low‐caloric foods (<2 kcal/g). The prices of the high‐caloric foods were then varied (75%, 100% (reference price), and 125%) to determine if TSD affects the flexibility of food purchasing. Before the task, participants received a standardized breakfast, thereby minimizing the potential confound produced by hunger. In addition, morning plasma concentrations of the orexigenic hormone ghrelin were measured under fasting conditions.</p> </sec> <sec id="oby20579-sec-0003" sec-type="section"> <title>Results</title> <p>Independent of both type of food offered and price condition, sleep‐deprived men purchased significantly more calories (+9%) and grams (+18%) of food than they did after one night of sleep (both <italic>P</italic> < 0.05).
