Appetite and Glucose Responses
Conditions
Brief summary
The aim of this study is to determine the effects of bean physical form (whole versus blended) and Beano on postprandial responses. The postprandial responses the investigators will examine include blood glucose, appetite, metabolic rate, physical symptoms, and mood. To accomplish this aim the investigators will conduct a randomized, placebo-controlled trial in overweight and obese but otherwise healthy (non-diabetic) men and women
