Does
Metabolift Work
In order to
answer the question "Does Metabolift Work?" we need
to first understand how Metabolift (and
other fat burners) work.
Let's
take a look at Metabolift's two primary mechanisms of action within
the body: 1) Thermogenesis, and 2) Appetite suppression.
Our bodies have three broad heat modulators: the thyroid hormones,
the adrenergic hormones (epinephrine and the weaker norepinephrine),
and the prostaglandin hormones. Metabolift and other ephedrine/caffeine-based
fat burners seem to mimic and intensify the adrenergic hormones,
which mobilize fatty acids from your triglyceride stores and force
the skeletal muscles to use more fatty acids for heat production.
The ephedrine/caffeine stack can therefore be a good aid to weight
loss, but it can also cause side effects if not used with care.
(For more information about side effects associated with Metabolift,
see Metabolift side effects.)
Thermogenesis
Ephedrine
Ephedrine has been shown to increase the effectiveness of thermogenesis
(fat burning) in the body. It has powerful effects on the cellular
mechanisms that control fat release from fat cells. Some of these
effects include contributing to the release and blocking the re-uptake
of the neurotransmitter norepinephrine. This gives norepinephrine
the ability to continuously stimulate receptors in your body,
causing fat cell "flood gates" to open and facilitate
fat loss. The Chinese herb ma huang (Ephedra sinica) is the chief
natural source of the ephedrine family of compounds, although
there are other minor sources, such as Sida cordifolia.
Caffeine
The second key thermogenic ingredient – caffeine –
is a methylxanthine that stimulates hormone-induced fat burning.
The caffeine source in Metabolift is guarana. Caffeine works by
increasing free fatty-acid concentrations and adrenaline levels.
This results in greater lipolysis (oxidation of fats for energy),
which can drain your fat stores over time. This change in a muscle's
utilization of energy substrates can have a profound effect on
fat loss. Caffeine also heightens mental alertness, which can
positively affect your motivation to exercise and create the caloric
deficit needed to lose body fat.
Appetite Suppressant
The ephedrine/caffeine stack reduces appetite, which seems to
account for about three-quarters of the weight loss you might
experience. The other one-quarter is accounted for by increased
thermogenesis.
At fairly high doses, versions of this stack can cause a significant
increase in the number of calories burned each day. In one trial
published just this year, 50 mg of ephedrine was given to volunteers
three times per day. Under these controlled conditions and using
very precise monitors to measure energy expenditure, it was found
that 3.6% more energy was expended in a 24-hour period.
The
only way to really find out the answer to the question "Does
Metabolift Work" is to actually try it out for yourself.
