1. Values are mean ± SDs or medians (IQRs). BC was the consumption of a standardised breakfast for seven consecutive days; BO was the abstinence from all energy-providing nutrients until at least 10:30 for seven consecutive days. PA, physical activity; VAS, visual analogue scale; NO, non-overweight; OW, overweight; OB, obese; RMR, resting metabolic rate. 2. BMI classification according to the International Obesity Task Force [33]. 3. Five stages of breast and pubic hair development described by Tanner [36].4. Less than 50 kcal consumed before 10:30.
