Physical and Biochemical Characteristics of Subjects at baseline and in response to 7-days of overfeeding1.

1All values are mean ± SE. Homeostasis model assessment of insulin resistance (HOMA-IR) and of B cell function (HOMA-β); NA, not applicable. Subjects were classifed based on adiposity recommendations by Bray as normal weight (8–20.9%), overweight (21–25.9%), or obese (>26%). Obesity status and overfeeding response were analyzed by 2-factor mixed-model ANOVA for repeated measures (IBM SPSS Statistics 19).2Significant difference between normal weight, overweight, and obese subjects at baseline, P3Significant difference between normal weight and obese subjects at baseline, P4Significant difference between obese and normal weight and obese and overweight, at baseline, P5Significant difference due to overfeeding, P6Significant overfeeding x adiposity status interaction, P
