Detailed description
The present study will compare the nutritional response to the realisation of an acute exercise right before or right after lunch in adolescents with obesity. 18 adolescents with obesity will be asked to randomly complete three experimental sessions: i) one control session (rest); ii) one session with an acute exercise realized right before lunch; iii) one session with an acute exercise realized right after lunch. Their ad libitum energy intake will be assessed during lunch as well as at dinner time. Appetite feelings will be assessed at regular intervals and their food reward in response to the lunch will also be assessed.
