Fig. 3. Changes in salivary cortisol levels in women after eating a high-protein meal (•, 32% energy as protein; 630 kcal) and an equicaloric low-protein meal (
, 5% energy as protein). Data are expressed as mean ± SE (N = 9). *Significantly greater than cortisol levels after the low-protein meal: at 30 minutes, t(8) = 2.30, at 60 minutes, t(8) = 2.59, p < .025, 1-tail. +Significantly less than baseline (12:30 PM) cortisol levels, t(8) = 3.92, p < .01. #Significantly greater than baseline cortisol levels, t(8) = 2.27, p < .05, 1-tail. (Note that time is give in European or military form.)
