The number of food items eaten was not associated with
participant BMI (mean 24.81; SD ¼ 3.30; r ¼ 0.06; P > 0.61);
number of daily supplements taken (mean 0.69; SD ¼ 0.60; r ¼
0.11; P > 0.34); or age (r ¼ 0.03; P > 0.82). The data on food
items eaten was submitted to a 2 (manipulation: weight loss
versus placebo) 2 (food items: healthy versus less healthy)
mixed-factorial analysis of covariance, treating the time since
last meal as a covariate. Importantly, a main effect of supplement
manipulation revealed that, on average, participants presumably
taking weight loss supplements ate a greater number of
food items than did control subjects [F(1, 67) ¼ 12.07; P < 0.001;
partial h2 ¼ 0.15] (Table 1). This finding suggests that individuals
may be susceptible to the risk for excessive food intake after
