  Purpose

In this research study, investigators are interested in how certain dietary fibers in the diet affect certain hormones released from your intestine after eating and how these influence your appetite. The study hypothesis is that certain fibers will slow digestion and absorption of nutrients thereby optimizing fullness,reducing food intake and limiting insulin response in pre- and post-menopausal women.

Primary Outcome Measures:
  • To investigate the effects of viscous polysaccharide fibers on postprandial satiety and meal-associated metabolic response patterns. [ Time Frame: 0, 20, 40, 60, 90, 120, 150, 180, 210, 240 minutes ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • To characterize the subjective and behavioral satiety responses to study-specific preload meals varying in viscous fiber content as well as determine the relationship of these satiety responses to the preload-associated physiological responses. [ Time Frame: 0, 20, 40, 60, 90, 120, 150, 180, 210, 240 minutes ] [ Designated as safety issue: No ]

Enrollment: 22

Estimated Study Completion Date: March 2014
Estimated Primary Completion Date: March 2014 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Placebo Comparator: High GI low fiber meal
No fiber control meal
Dietary Supplement: No fiber

The High GI low fiber meal consists of 0 grams fiber with total kcal of 573 with 63% energy from carbohydrates, 24% energy from fat and 13% energy from protein.

Test meal consists of breakfast meals containing muffins and yogurt beverage/shake.

Active Comparator: Low GI high fiber viscous meal
80:20 ratio of viscous polysaccharide fiber to insoluble non-viscous producing fiber
Dietary Supplement: Low GI high fiber viscous meal

Test meal consists of 12 grams of fiber (9 grams soluble and 3 grams insoluble). The ratio is 80:20 ratio of viscous polysaccharide fiber source (psyllium husk) to insoluble non-viscous producing fiber source (cellulose).

Total kcal provided as 560 kcal with 63% energy from carbohydrates, 24% energy from fat and 13% energy from protein. Test meal consists of breakfast meals containing muffins and yogurt beverage/shake.

Active Comparator: Low GI high fiber non-viscous meal
20:80 ratio of viscous polysaccharide fiber source to insoluble non-viscous producing fiber
Dietary Supplement: Low GI high fiber non-viscous

Test meal consists of 11 grams of fiber (3 grams soluble and 8 grams insoluble). The ratio is 20:80 of viscous polysaccharide fiber source (psyllium husk) to insoluble non-viscous producing fiber source (cellulose).

Total kcal provided as 560 kcal with 63% energy from carbohydrates, 24% energy from fat and 13% energy from protein. Test meal consists of breakfast meals containing muffins and yogurt beverage/shake.
