Changes in fasting acylated ghrelin and GLP-1 concentrations of participants exercising to expend 1,500 or 3,000 kcal/wk for 12 wk

	Baseline	Week 12	Adjusted Difference (95% CI)
GLP-1, pM	59.2 ± 4.1	52.6 ± 3.5	−6.7 (−11.6, −1.8)*
Acylated ghrelin, pg/ml	842.6 ± 65.0	909.1 ± 64.3	66.5 (8.6, 124.4)*
Peptide-YY, pg/ml	202.8 ± 14.0	189.9 ± 14.1	−13.1 (−35.8, 9.7)*
Myostatin, mg/l	41.0 ± 1.4	42.3 ± 1.4	1.0 (−0.8, 2.7)
Irisin, µg/ml	9.0 ± 0.5	8.8 ± 0.6	−0.3 (−1.1, 0.43)
Insulin, mIU/l	9.0 ± 1.0	8.2 ± 0.9	−0.9 (−2.4, 0.69)
Glucose, mg/dl	94.5 ± 1.4	93.9 ± 1.4	−0.6 (−3.3, 2.0)

Values are means ± SE. GLP-1, glucagon-like peptide 1; CI, confidence interval.
