Fig. 1. Glucose responses (mmol/L) of men (___) and women (_ _ _) to glucose alone ({blacklozenge}) 1 g/kg body weight, or with glucose + 0.08 (low •), 0.17 (medium {blacktriangleup}), and 0.33 g/kg body weight (high {blacksquare}) of Z-trim. Least-squares means, SEM 0.37. Time: p < 0.0001, gender: p = 0.02, time*fiber p < 0.0001, time*gender*fiber: p = 0.04.

Fig. 2. Insulin responses (pmol/L) of men and women combined (___) to glucose alone ({blacklozenge}) 1 g/kg body weight) or glucose + (low •) 0.08, (medium {blacktriangleup}) 0.17, and (high {blacksquare}) 0.33 g/kg body weight of Z-trim. Least-squares means, SEM 75, n = 24, time p < 0.0001, time*fiber: p < 0.0001.

Fig. 3. Glucagon responses (ng/L) of men (___) and women (_ _ _) to glucose alone ({blacklozenge}) 1 g/kg body weight) or glucose + (low •) 0.08, (medium {blacktriangleup}) 0.17, and (high {blacksquare}) 0.33 g/kg body weight of Z-trim.
