Detailed Description
The objective of this project is to test whether consuming a whole food that naturally contains resistant starch (RS), such as pulses, increases fat oxidation. The primary hypothesis is that consuming a RS-rich meal in which the RS is derived from a whole food (i.e., pinto beans, pinto bean flour) will increase postprandial fat oxidation to a greater extent than consuming a meal low in RS but containing the same amount of energy and macronutrient content.

Outcome Measures
Primary Outcome Measures
- Fat, carbohydrate, and protein utilization [5 hours after meal consumption]
