This study whether aspartame increases hunger. The study included groups of 10 male and 10 female subjects who chewed a gum containing one of four concentrations of aspartame (0.05%, 0.3%, 0.5%, or 1.0%) or unsweetened gum for 15 minutes, or were given nothing.
The study found:
(a) Relative to groups given nothing or unsweetened gum to chew, groups given the aspartame sweetened gum had increased hunger.
(b) The highest aspartame concentrations had a time-dependent, two-phase effect on appetite, producing a transient decrease followed by a sustained increase in hunger.
The results of the study show that aspartame increases hunger.
