  1. Mean ± SD shown for pre and post values, with mean ± 95% confidence intervals used to express delta change scores. Differences between the two days were analysed by two-tailed, paired, Student’s t tests or non-parametric equivalent where data were non-normally distribution (Shapiro–Wilk’s p > 0.05), p-values shown.
  2. CI confidence intervals, L1-L4 central fat estimated between lumbar regions L1-L4 using DEXA, PAL physical activity level (total energy expenditure/basal metabolic rate), ALT alanine transaminase, HDL high-density lipoprotein, HOMA-IR homoeostasis model assessment for insulin resistance, LDL low-density lipoprotein, ND not determined, NEFA non-esterified fatty acids.
  3. aT-AUC for insulin and glucose and Matsuda-ISI represent n = 11 due to incomplete data. All blood measures are fasting samples unless otherwise stated.
