All associations were analyzed using general linear models; β indicates the estimated increase/decrease of each food intake measures (i.e. kcal or g), attributable to one unit increase of anthropometric variables(i.e. 1 kg*m−2) or energy expenditure (i.e. 1 kcal); FFMI fat free mass index; FMI fat mass index; 24h EE 24 hour energy expenditure; All models are described in detail in the methods section;
