Correlation coefficients of food intake, FBS, and serum insulin with the expression of cardiac TNF-α and apoptotic proteins at the last week of the study.

	TNF-α/β-actin	FasL/β-actin	Cleaved caspase-9/procaspase-9	Cleaved caspase-8/procaspase-8	Cleaved caspase-3/procaspase-3
Food intake (week 13)	0.698∗	0.746∗	0.786∗	0.682∗	0.619∗
FBS	0.570∗	0.740∗	0.684∗	0.682∗	0.751∗
Serum insulin	-0.576∗	-0.755∗	-0.639∗	-0.759∗	-0.781∗

TNF-α: tumor necrosis factor-α; FasL: Fas ligand; BW: body weight; FI: food intake; FBS: fasting blood glucose. P based on the Pearson correlation test (n = 35). P < 0.05 was regarded as statistically significant. ^∗P < 0.001.
