Fig. 1. Glucose responses (mmol/L) of men (___) and women (_ _ _) to glucose alone () 1 g/kg body weight, or with glucose + 0.08 (low ), 0.17 (medium ), and 0.33 g/kg body weight (high ) 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 () 1 g/kg body weight) or glucose + (low ) 0.08, (medium ) 0.17, and (high ) 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 () 1 g/kg body weight) or glucose + (low ) 0.08, (medium ) 0.17, and (high ) 0.33 g/kg body weight of Z-trim. Least-squares means, SEM 3.5. Diet: p = 0.0013, time: p = 0.0018, gender: p = 0.0018, period*fiber: p = 0.0008, period*gender: p < 0.0001, period*time*gender: p = 0.0017.
