A Randomized Double‐Blind Crossover Study of the Antiobesity Effects of Etiocholanedione

Abstract
Etiocholanedione (ED), a natural metabolite of dehy‐droepiandrosterone, has antiobesity effects in animals when given orally and is nontoxic. We carried out a trial of oral ED in obese humans. In a 20‐week randomized double‐blind crossover study, 14 subjects lost significantly more weight and body fat during treatment with oral ED, 4 gm daily, than during placebo administration. Mean weight loss during ED administration was 2.8 ± 5.5 kilograms, which was equivalent to 0.53 k 0.91 kilograms per week per 100 kilograms of body fat; mean weight change during placebo administration was essentially zero: M.21 ± 4.2 kg, or 4.04 ± 0.74 kg/wk/100 kg body fat. The difference between the weight changes in the two periods was significant: for A kg, P.
