The protein leverage hypothesis (PLH) predicts that protein appetite will
stimulate excess energy intake, and consequently obesity, when the proportion of
protein in the diet is low. Experimental studies support the PLH, but whether protein
leverage can be used to understand socioeconomic (SES) variation in obesity is
unknown. The objective of this study was to test two hypotheses from the PLH under
non-experimental conditions. Consistent with the PLH, we expect that (1) absolute
protein intake will be similar across populations, here defined as SES groups and, (2)
the proportion of protein in the diet will be inversely associated with energy intake.
