A total of 18 adolescents with obesity, aged 12-16 years olds will complete three experimental sessions in a randomized order: i) low energy turnover; ii) Moderate energy turnover and ; iii) High energy turnover. Their ad libitum energy intake at dinner will be assessed through an ad libitum buffet-type meal, their food reward assessed right before the dinner meal and their appetite sensation at regular intervals during the day.
The aim of the study is to compare the effect of a low versus moderate versus high energy turnover on energy intake, appetite and food reward, in adolescents with obesity. 18 adolescents with obesity will then complete three experimental sessions in a randomized order: low, high and moderate Energy turnover.
