Energy Intake, Exercise and Constitutional Leanness (Nutrilean)

February 8, 2024 updated by: University Hospital, Clermont-Ferrand

Identification of the Physical and Dietary Profile on Constitutionally Lean People: the NUTRILEAN Study

The aim of this study will be to identify the physical and dietary profile of adult women presenting constitutional leanness (CL), comparatively with normal-weight peers and BMI-matched women with anorexia nervosa. After an evaluation of their daily energy intake, physical activity level, body composition, aerobic capacities and muscle strength, women from the normal weight and CL groups will be asked to realized laboratory sessions to evaluate their energy intake and appetite feelings responses to acute exercise

Study Overview

Detailed Description

Body composition (using X-ray absorptiometry), muscle strength (biodex), daily energy intake (dietary record), food preferences (Leeds Food Preference Questionnaire) and physical activity level (GT3X accelerometers) will be assessed among women with constitutional leanness normal weight women and women with anorexia nervosa. The CT and NW groups will then be asked to randomly realized three experimental session: i) a rest session with an fixed lunch meal; a rest session with an ad libitum meal ; iii) an exercise session with an ad libitum meal. Their ad libitum energy intake will be assessed during the two last sessions. Appetite feelings will be assessed at regular intervals and their food reward in response to the lunch will also be assessed.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Constitutional leanness
condition without exercise / rest condition. The participants will be asked to remain quiet and at rest during the morning and will receive a fixed meal at lunch. Their food reward will be assessed before and after lunch. Their appetite feelings will be assessed at regular intervals.
condition without exercise / rest condition. The participants will be asked to remain quiet and at rest during the morning and will receive an ad libitum meal at lunch. Their food reward will be assessed before and after lunch. Their appetite feelings will be assessed at regular intervals.
condition with an acute exercise set 30 minutes before the lunch meal that will be served ad libitum This will be a 30-minute exercise set at 65% of their capacities (cycling), 30 minutes before lunch.
Experimental: Normal weight

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change in energy intake measured during the ad libitum buffet meal (in kcal).
Time Frame: day 1 , day 8
food intake will be measured ad libitum during a lunch buffet. The participants 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.
day 1 , day 8

Time Frame: day 1
the percentage of body fat and the quantity of fat mass will be assessed using X-ray absorptiometry (DXA)
day 1
Physical activity level
