aRate of weight loss expressed as percentage of starting body weight lost per week
bRefers to the percentage change in starting mass calculated as follows: ([start mass – end mass] ÷ start mass) ×100%
cEI: energy intake expressed as metabolisable energy (in kJ [Kcal]) per kg of metabolic body weight (BW0.75) per day
