Can a naturally occurring hormone that promotes growth and development
be a dieter's dream come true? The quest for an easier weight loss
solution has some people taking human growth hormone (HGH) in pills,
powders, and injections.
A few small studies have linked HGH powder, human growth hormone powder, gh powder
injections with fat loss and muscle gain. But the changes seen were
minimal -- just a few pounds -- while the risks and potential side
effects are not. And experts warn that HGH is not approved by the Food
and Drug Administration (FDA) for weight loss.
HGH is produced by the pituitary gland to fuel growth and development in
children. It also maintains some bodily functions, like tissue repair,
muscle growth, brain function, energy, and metabolism, throughout life.
HGH production peaks during the teenage years and slowly declines with
age. Studies have shown that obese adults have lower levels than
normal-weight adults. And these lower levels of HGH have some people
wondering whether a boost of HGH could enhance weight loss, especially
in the obese.
HGH has also gained a reputation as a muscle builder, and its use is
banned in the Olympics and other sports. However, there is little solid
evidence that it can boost athletic performance.
Early Study Sparks Interest in HGH
Interest in using HGH for weight loss stems from a 1990 New England
Journal of Medicine study that showed injections of synthetic HGH
resulted in 8.8% gain in muscle mass and 14% loss in body fat without
any change in diet or exercise. Although this study appeared to be
promising, many later studies have shown no such benefit.
In March 2003, the New England Journal of Medicine took the unusual step
of denouncing misuse of the 1990 study, pointing out that subsequent
reports provide no reason to be optimistic.When adults with an HGH
deficiency resulting from pituitary disease are given HGH replacement,
it improves body composition -- increasing bone mass and muscle mass and
decreasing fat stores.
