Data presented as means and standard deviations of the raw data; all data analyzed with intention to treat, mixed effects regression analyses corrected for any effect of BMI, sex, and age.

^*Significantly different from baseline.

^†Significantly different from 3 months data.

^‡In Australia, the average full time work week equates to 37.5 hours per week or 7.5 hours per day.
