⁽¹⁾CON: control; HFD: high fat diet; HFD + PO5%: high fat diet + 5% P. oleracea powder; HFD + PO10%: high fat diet + 10% P. oleracea powder. ⁽²⁾FER (food efficiency ratio) = body weight gain/food intake per week. ⁽³⁾Values are the mean ± SE (n = 8/group). ^(a–c)Values with a different superscript in the same row are significantly different at by Duncan’s multiple range test. NS: not significant.
