Ik weet niet in hoeverre dit klopt, maar het onderstaande komt uit The Rapid Fat Loss Handbook van Lyle McDonald:
And then there’s yohimbe (or yohimbine HCL which is the drug form), a herb that helps with fat
mobilization, especially from stubborn fat areas like women’s hips and thighs. The mechanism of action
of yohimbe is slightly up to debate. Some research suggests that its effects are mediated through
inhibition of one of the hormone receptors on fat cells (the details of this system are in my Ketogenic Diet
book and The Ultimate Diet 2.0 book), other data suggest that it works by increasing hormone release
from the nerve terminals. In either event, yohimbe seems to particularly help with stubborn fat deposits
especially women’s hip and thigh fat. Men’s abdominal and low-back fat may also benefit. An
upcoming project of mine will deal in detail with getting rid of these stubborn fat depots.
But, before you run out and stock up on yohimbe, a couple of things. First is that if you’re not
already reasonably lean (I’d say dieting category 1 or maybe 2) to begin with, yohimbe won’t be of
much use to you. The body will take fat off from the most readily accessible areas first and stubborn fat
is stubborn for a reason.
Additionally, yohimbe, especially the herbal form, can cause all kinds of weird ass side-effects.
People often report a combination of sweats and chills along with a feeling that their heart is going to
come out of their chest when they exercise (yohimbe also improves blood flow to the genitals which
can lead to some potential embarrassment at the gym; it does not, contrary to popular belief, affect
testosterone levels). Finally, yohimbe is best used prior to aerobic activity (the aerobics are necessary
to burn off the now mobilized fatty acids) although it still might have an effect for a lean dieter doing the
crash diet without aerobics.
As one major caveat, you should never (NEVER) mix EC and yohimbe; in fact, you shouldn’t
take them within about 4 hours of one another. The reason is that the side effects of each will multiply
and both blood pressure and heart rate can really jump.If you decide to use yohimbe (again, the yohimbine HCL form is the better choice; less side
effects) the effective dose would be 0.2 mg yohimbe per kilogram of bodyweight or about .1 mg per
pound consumed with 100-200 mg of caffeine. This would be taken 30-60 minutes before lowintensity
aerobic activity (preferably first thing in the morning before eating). So a 150 lb dieter would
get just under 15 mg of yohimbe. As with EC it’s a good idea to start with a half-dose to assess your
tolerance. If you are also using the EC stack, your doses should be taken no closer than 4 hours to the
dose of yohimbe/caffeine. So you could do a yohimbe/caffeine combo at 7am prior to morning
aerobics and take EC at noon and 4 pm.
