结局指标
主要结局
Change in muscle protein synthesis from baseline to 16 weeks
时间窗: Measured at week 0 (baseline) and week 16
The investigators will determine the rate of incorporation of stable isotope amino acid tracers in skeletal muscle protein on average resting muscle protein synthesis rate (% new muscle protein per hour) and will be performed at baseline and 16 weeks after caloric restriction or control diet.
次要结局
- Change in insulin sensitivity from 0 (baseline) and 16 weeks(Measured at week 0 (baseline) and week 16)
