  1. 1 m ean ± SEM, VLCARB = very low carbohydrate (n = 24) VLF= very low fat (n = 22) HUF = high unsaturated fat (n = 21)
  2. MUFA = monounsaturated fat, PUFA = polyunsaturated fat
  3. 2 Three days (2 week days and 1 weekend day) of dietary data were analysed at weeks 2, 4, 6 and 8 during the weight loss period and at weeks 10 and 12 during the maintenance period. No significant differences were found between the four diet records in the weight loss period or between the two records for the maintenance period, so data for recordings in each period were averaged.
  4. 3 Significant main effect of diet using one way ANOVA with all diets significantly different from each other (P < 0.01)
  5. 4 Significant main effect of diet using one way ANOVA; VLF vs HUF (p = 0.126) and VLCARB different to VLF and HUF (P < 0.01)
  6. 5 Significant main effect of diet using one way ANOVA; VLF different to VLCARB and HUF (P < 0.05)
