Data presented as mean ± SE. PROMOD denotes moderate protein condition; PROHIGH denotes high protein condition. Time-point 0 refers to resting concentrations pre-feeding; other time-points refer to corresponding time post-breakfast meal. * denotes significant differences to 0 time-point within condition only (p ≤ 0.036). a denotes overall difference to pre intervention responses (p = 0.015).
