Fig. 2. Effects of two identical high-protein midday meals on salivary cortisol levels, compared with a day on which no meal was served (Meal A ; Meal B •; No Meal ). Data are expressed as mean ± SE (N = 10). ab, -cortisol at this time differed significantly from No Meal for Meal A and for Meal B: Bonferroni t tests, t (9) = 3.44, p < .05; t(9) = 4.78, p < .01, respectively. For unit conversion, µg/dl = nmol/liter x .03625. (Note that time is given in the European or military form.)
