Three
capsules were taken three times daily, one-half hour
before meals (a total daily amount of 3.15 g of Irvingia
gabonensis seed extract) with a glass of warm water. Capsules
were identical in shape, colour and appearance, with
neither patients nor researchers knowing what capsule
they received. During the experimental period, subjects
were examined weekly, with their body weight, body fat,
waist and hip circumferences recorded each time. Subjective
findings such as increased or decreased appetite, feeling
of lightness and gastrointestinal pains were
individually noted. Side effects of the active extract, if any
were also solicited and noted during each visit. The subjects
were also interviewed about their physical activity
and food intake during the trial, and were instructed to eat
a low fat diet (1800 Kcal) as well as keep a record for seven
consecutive days (using household measurements).
