Interesting article from Harvard:
"So the National Institutes of Health (NIH) funded a randomized, double-blind study of the hormone in slightly overweight adults between the ages of 65 and 78. Half of the 56 participants took 50 milligrams of DHEA daily — a fairly typical dose — while the other half took a placebo.
DHEA didn’t produce dramatic weight loss. People taking the hormone lost, on average, about 2 pounds, while those taking the placebo gained a little more than 1 pound. The results for abdominal fat were more notable. At the end of the six-month study, MRI images showed that the women taking the hormone had shed about 10% of their abdominal fat and the men lost about 7%. That may not seem like much, but the fat that accumulates around our middles is one of the main reasons why being heavy is so unhealthy.
Interestingly, the study also showed that DHEA increases the levels of testosterone in women, but not in men. Levels of estradiol, the most potent, naturally occurring estrogen, went up in both women and men. The hormone also increased the levels of insulin-like growth factor 1 (IGF-1), a protein with a wide range of effects on various tissues."
