Animals fed control (CON), fish oil enriched (FO), or flaxseed oil enriched (FSO) diets had no differences in weekly food intake (A). Animals fed the enriched diets began to demonstrate heightened weight gain compared to control at week 5, an effect that continue through the study (p < 0.05 versus CON at week 5–6, p < 0.001 versus CON at week 7) (B). Animals fed FO and FSO enriched diets consumed a greater caloric load compared to CON (p < 0.01 and 0.001, respectively) (C). There were no notable or significant differences in plasma GLP-1 levels (D) or fasting blood glucose (E) in animals fed the n-3 enriched diets compared to control. * denotes p < 0.05, *** denotes p < 0.001 versus CON.
