Energy Intake, Exercise and Energy Replacement

Does Energy Replacement Modify Post-exercise Energy Intake in Adolescents With Obesity?

The aim of the present study is to compare the effect of an exercise alone versus. An exercise followed by the ingestion of an energy replacement snack on the following energy intake, food reward and appetite feelings in adolescents with obesity.

The present study will compare the nutritional response to the realisation of an acute exercise with and without an energy replacement snack on the following energy intake 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 during the morning; iii) one session with the same exercise followed by a snack covering the exercise-induced energy expenditure. Their ad libitum energy intake will be assessed at the following meal 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.
