About

The aim of the present study is to compare the effect of iso-energetic energy deficits induced by exercise or dietary restriction on energy intake and appetite feelings in adolescents with obesity

Full description

The present study will compare the nutritional response to an energy deficit of 400 kcal induced once by realisation of an acute exercise set at moderate intensity and once by a dietary restriction imposed at lunch (compared with a control condition). 18 adolescents with obesity will be asked to randomly complete three experimental sessions: i) one control session (CON); ii) one session with an exercise-induced energy deficit (Def-EX); iii) one session with an energy restriction-induced energy deficit (Def-EI).

Their ad libitum energy intake will be assessed during dinner time. Appetite feelings will be assessed at regular intervals and their food reward in response to the lunch will also be assessed.
