To investigate whether appetite response to a high-protein test meal varies inversely with habitual protein intake, the satiating influence of dietary protein was investigated in 14 subjects. Subjects were divided into two groups on the basis of habitual protein intake: means of 1.0 g/kg/day (LP) and 1.4 g/kg/day (HP). Appetite was assessed in each group following high protein meals (test a). A 13-day period of dietary manipulation increased differences in protein intake between groups to a mean of 0.75 g/kg/day (LP) and 1.96 g/kg/day (HP) and a second satiety test (b) was performed. A third lest (c) was performed in the HP group after protein intakes were reduced for 2 days to a mean of 0.85 g/kg/day. Differences in satiety were most marked, with significant correlations between satiety after the three meals and daily protein intake (r = -0.36). LP satiety was significantly greater than HP after test b (p = 0.025), and approached significance when satiety response during LPb was compared with HPc (p = 0.07). Results support the hypothesis that the satiating effect of dietary protein varies inversely with habitual protein intake. (C) 2000 Academic Press.
