Appetite Response to Exercise- Versus Energy Restriction-induced Energy Deficit in Adolescents With Obesity.

Not Applicable

Completed

• Conditions: Pediatric Obesity

• Registration Number: NCT04739189
• Lead Sponsor: University Hospital, Clermont-Ferrand

Brief Summary

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

Detailed 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.

Primary Outcome Measures

Name	Time	Method
Change from different intervention of energy intake measured during an ad libitum buffet meal (in kcal)	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.

Secondary Outcome Measures

Name	Time	Method
Hunger feelings	day 1, day 8, day 15	hunger area under the curve will be assessed using visual analogue scale through a the day
Food reward	day 1, day 8, day 15	The participants will be asked to complete a validated computer-based procedure to measure food reward (Leeds Food Preference Questionnaire; LFPQ)
