Outcome

Type	Measure	Description	Time frame	Safety issue
Other	Mood	Mood will be assessed using the Profile of Mood States (POMS) questionnaire. The POMS measures six different dimensions of mood swings over a period of time. These include: Tension or Anxiety, Anger or Hostility, Vigor or Activity, Fatigue or Inertia, Depression or Dejection, Confusion or Bewilderment. A five-point scale ranging from "not at all" to "extremely" is used to assess participant mood states.	Change in sleep quality from baseline (day 0) to 16 weeks.
Other	Strength	Strength will be assessed using a standard hand-grip dynamometer .	On day 1 and day 112 (final day of 16-week intervention) of study.
Other	Glucose	Intravenous blood samples will be collected and glucose measured using a commercial kit.	On day 1 and day 112 (final day of 16-week intervention) of study.
Other	Insulin	Intravenous blood samples will be collected and insulin measured using a commercial kit.	On day 1 and day 112 (final day of 16-week intervention) of study.
Other	Blood lipids	Intravenous blood samples will be collected and blood lipids measured using a commercial kit.	On day 1 and day 112 (final day of 16-week intervention) of study.
Primary	Sleep Quality	Pittsburgh Sleep Quality Index (PSQI) will assess sleep quality and disturbance. This is a elf-rated questionnaire which assesses sleep quality and disturbances over a 1-month time interval. Nineteen individual items generate seven "component" scores: subjective sleep quality, sleep latency, sleep duration, habitual sleep efficiency, sleep disturbances, use of sleeping medication, and daytime dysfunction. The sum of scores for these seven components yields one global score. Each item is weighted on a 0-3 interval scale. The global PSQI score is then calculated by totaling the seven component scores, providing an overall score ranging from 0 to 21, where lower scores denote a healthier sleep quality.	Change in sleep quality from baseline (day 0) to 16 weeks.
Secondary	Dietary intake	Dietary intake will be measured using 3-day, weighed food records.	Change in dietary intake from baseline (day 0) to 16 weeks.
Secondary	Sleep Quantity	Sleep duration will be measured using Actigraph monitors worn on the wrist.	Change in sleep quantity from baseline (day 0) to 16 weeks.
Secondary	Body composition	Body composition will be measured using dual x-ray absorptiometry (DEXA).	On day 1 and day 112 (final day of 16-week intervention) of study.
Secondary	Resting energy expenditure (REE)	REE will be measured using indirect calorimetry.	On day 1 and day 112 (final day of 16-week intervention) of study.
Secondary	Orexin	Intravenous blood samples will be collected and orexin measured using a commercial kit.	On day 1 and day 112 (final day of 16-week intervention) of study.
