Abstract
Objective: To examine the effects of ghrelin on appetite and energy expenditure in lean, obese and postgastrectomy subjects. Design: A randomized, double-blind, placebo-controlled study. Patients: Nine lean subjects (mean body mass index (BMI) 23.5±3 kg/m2) and nine morbidly obese subjects (mean BMI 51.4±10 kg/m2) and eight postgastrectomy subjects (mean BMI 22.4±1.0 kg/m2). Interventions: Subjects were infused with either intravenous ghrelin (5 pmol kg-1 min -1) or saline over 270 min. They were given a fixed energy breakfast followed by a free buffet lunch towards the end of the infusion. Main outcome measures: Visual analogue scales were used to record hunger and energy expenditure was measured by indirect calorimetry. Results: Ghrelin increased energy intake at the buffet lunch in lean subjects (a 41% increase, P
