The aim of
the present work was to test
the reproducibility of a personalized in-laboratory
ad libitum buffet meal in assessing energy and macronutrient intake in obese adolescents.
Methods
Twelve 13.5 ± 1.5 years old obese adolescent girls were asked to complete three identical experimental sessions during which an ad libitum buffet meal was presented at lunch time. The buffet was personalized based on food preference questionnaires, presented usually consumed food items and excluded preferred foods. Total energy intake and the energy ingested derived from each macronutrient were assessed by investigators using the Bilnuts nutritional software.
Results
Mean body mass was 87.0 ± 13.7 kg and mean BMI was 32.2 ± 4.9 kg/m2. Mean FM percentage was 39.1 ± 4.4% and FFM was 50.6 ± 7.7 kg. There was no significant difference between total energy intake, the percentage of intake related to fat, protein or Carbohydrates (CHO) between the three sessions. The Intraclass Correlations (ICC) observed for total energy intake was 0.99. ICC for Protein, Fat and CHO were 0.38; 0.96 and 0.81 respectively. The Bland & Altman visual analysis revealed an important agreement between meals.
Conclusion
The proposed personalized in-laboratory ad libitum test meal produces is a reproducible methods to assess energy and macronutrients intake in obese adolescent girls.
