  1. EI, energy intake; N/A, not available; pBMR, predicted basal metabolic rate. Energy intake conversion factor:1 kJ = 0.239 kcal
  2. Participants included all those who had completed the dietary record. All continuous values are presented as mean (standard deviation). Body mass index was calculated as body weight (kg) divided by height squared (m2)
