Within-subject relationships between energy intake [results of suppression of ad libitum energy intake after the intraduodenally infused whey-protein loads have been published previously [31]] and area under the curve (AUC 0–60 min) of total, essential amino acids (histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine), branched chain amino acids (isoleucine, leucine, and valine), and individual amino acids in healthy older and younger men combined (n = 20; n = 19 for histidine), younger men (n = 10; n = 9 for histidine), and older men (n = 10), ranked in order of the strongest to weakest R square in the combined group. Within-subject correlations were determined using a general linear model with fixed slope and random intercept. Statistical significance was accepted at p < 0.05.* p < 0.05, ** p < 0.005, *** p < 0.001.
