简要总结
The aim of the present study is to compare the effect of iso-energetic energy deficits induced by energy restriction alone or exercise + dietary restriction (Mixed deficit) on energy intake and appetite feelings in adolescents with obesity.
详细描述
The present study will compare the nutritional response to an energy deficit of 500 kcal induced once by dietary restriction alone and once by a mixed deficit (50% by exercise and 50% by dietary restriction) (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 a dietary-induced energy deficit (Def-EI); iii) one session with a mixed deficit (50% by exercise and 50% by dietary restriction) (Def-Mixed).
Their ad libitum energy intake will be assessed at dinner time. Appetite feelings will be assessed at regular intervals and their food reward in response to the lunch will also be assessed.

结局指标
主要结局
Change from different intervention of energy intake measured during an ad libitum buffet meal (in kcal).
时间窗: day 1, day 8, day 15
food intake will be measured ad libitum during a dinner buffet. The adolescents will be offered an ad libitum buffet-type meal composed based on their food intake preferences. Their intake will be weighted using an electronic food scale by a member of the investigation team and then analysed using Bilnuts software.
次要结局
- Hunger feelings(day 1, day 8, day 15)
- Food reward(day 1, day 8, day 15)
