Brief summary
The purpose of this research is to test how eating a meal containing beans impacts how participants' bodies use food for energy.
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.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Acute effects of consuming processed pulse-based food products on substrate utilization | 5 hours after meal consumption | The effect of consuming whole beans or bean-derived flour on the use of fat, carbohydrate, and protein for energy will be determine using whole room calorimetry. Fat, carbohydrate, and protein oxidation will be calculated as an absolute amount of grams per day and as a percentage of energy expenditure. |
