Kinetics of pleasure elicited by sweetness and the desire for other taste. The control (open circle) and obesity (OB) (closed circle) groups underwent 10 consecutive trials of tasting 24% w/v sucrose solution before and after weight loss by the OB group. The data corresponding to pleasure elicited by sweetness (A) and the desire for other tastes (B) are normalized to their baseline values at the first trial. Data are expressed as mean ± standard error. Asterisk indicates a simple main effect of significant difference of between-group comparison (* p < 0.05, ** p < 0.01).
