Lorcaserin decreased EI and appetite. At d 56, lorcaserin
decreased EI by 264 kcal over lunch and dinner compared
with placebo as a result of significantly larger reductions
in self-reported appetite and hunger. Even over
7 d during imposed weight stability, lorcaserin treatment
significantly reduced EI by 286 kcal over lunch and dinner.
Assumptions are required to extrapolate change in EI to
weight change (e.g. 7700 kcal/kg), and these calculations
are problematic because weight change was integrated
over 56 d and food intake was quantified only at lunch and
dinner on 2 d after the baseline measurement. Nonetheless,
differences in food intake change between the placebo
and lorcaserin group could explain approximately 80% of
the difference in weight loss between the groups. Additionally,
reductions in food intake were associated with
reductions in body weight, as expected. The food intake
results from this human trial are inconsistent with rodent
