Primary Outcome Measures

Name	Time	Method
Change in body weight by weight scale	Baseline to 52 weeks	Participant body weights will be measured on a kg scale

Secondary Outcome Measures

Name	Time	Method
Change in T2D diagnosis criteria	Baseline to 52 weeks.	T2D diagnosis will be determined according to American Diabetes Association criteria, which includes fasting glucose \<126 mg/dL or hemoglobin A1c \<6.5%.
Change in % fat free mass (FFM)	Baseline to 16 weeks.	Participant FFM will be measured by dual x-ray absorptiometry (DXA), which is the gold standard for measuring body composition.
Change in % FFM	Baseline to 52 weeks.	Participant FFM will be measured by dual x-ray absorptiometry (DXA), which is the gold standard for measuring body composition.
Change in % body fat	Baseline to 52 weeks.	Participant body fat will be measured by dual x-ray absorptiometry (DXA), which is the gold standard for measuring body composition.
