Abstract

Purpose: This study was designed to establish which protein supplement resulted in the greatest dietary-induced thermic effect.

Methods: Ten (n = 10) male subjects (25 ±1.7 yrs) completed a randomized, doubleblind, crossover investigation involving three separate resting-and-reclining energy expenditure measurements taken before and after consumption of a protein shake. Resting-and-reclining metabolic gas-exchange measurements were taken for 20 min; subjects then drank 32 oz of water with protein powder, after which 4 hr of additional resting-and-reclining gas-exchange measurements were taken at 15 min intervals.
Results: Oxygen consumption increased to a greater extent during the WHEY and SOY trials compared to the EGG.
Conclusion: Results suggest that there was no significant difference found between the whey and soy protein supplements, which produced the greatest DIT when compared to egg. Whey and soy resulted in a higher DIT than egg.
