Changes in body weight and adiposity of rats on either a HFD or HFD supplemented with 10% barley flour or wheat bran. Body weight (A) and adiposity (B) of WB, BF, and HFD-fed rats. Week 12 total fat mass (C) and lean mass (D). 24-h metabolic cage data at week 3 of dietary intervention; energy intake (E), meal size (F), meal number (G), energy expenditure (H), and respiratory exchange ratio (RER) (I). Data presented as mean ± SEM (n = 9–10 per group); *p < 0.05 wheat group from HFD, #p < 0.05 barley group from HFD; different letters indicate a significant difference between groups p < 0.05
