Methods: This study was performed according to a double-blind, randomized,
placebo-controlled, parallel-group design. Subjects aged 20 to 65 years
with a visceral fat area 90 cm2 were enrolled. Subjects were randomly assigned
to receive treatment for 12 weeks with G cambogia (containing 1000 mg of HCA
per day) or placebo. At the end of the treatment period, both groups were
administered placebo for 4 weeks to assess any rebound effect. Each subject
underwent a computed tomography scan at the umbilical level at –2, 0, 12, and
16 weeks.
