Feeding the Fat Burning Fire

 

In today’s weight conscious society, we are constantly searching for ways to both enhance and expedite fat loss.  Over the last decade or so, the popularity of “thermogenic” supplements has risen to the point of virtual obsession.  But do these supplements actually work, and are they safe?

Thermo, meaning “heat”, and genesis, meaning “creation of”, basically means that the body responds to certain substance by increasing its metabolism, thereby burning more calories  Different foods contain different substances that create this reaction through various internal avenues (hot peppers, coffee, tea, etc…).  Thermogenics are used to activate the body’s fat burning machinery, thus increasing the use of fat as a fuel source.

Perhaps the most widely known thermogenic aid is “ephedrine”, which is the synthetic equivalent of the natural herb, “ephedra”, an extract from the Ma Huang plant.  You may see Ma Huang, sida cordfolia, or E. gerardiana listed as ingredients in any given thermogenic supplement, and are all essentially the same thing with a different name.  Basically, ephedra and its derivatives stimulate the release of substances in the body that act on certain cell receptors that trigger the release of fat from cells into the bloodstream to be used for energy.

Caffeine is another common ingredient in thermogenic aids, and for good reason.  It is a central nervous system stimulant (increasing awareness and alertness), and stimulates the release of epinephrine (adrenaline), which serves to improve muscular contraction and the use of fat as a fuel source. 

The combination of both ephedrine and caffeine in one thermogenic supplement has proven to be very effective in shedding body weight, both with or without exercise.  As with any “magic pill”, there are potential adverse side effects associated with its use.  Individuals with existing high blood pressure, thyroid disease, depression, diabetes, prostate enlargement, peptic ulcers, or taking MAO inhibitors, should not use any supplement containing ephedrine.  Caffeine itself is a diuretic, which may cause excessive fluid and electrolyte loss, resulting in dehydration and impaired exercise ability.  Anyone thinking of taking a thermogenic aid should consult with their physician prior to doing so.

Research shows that consuming no more than 30mg of an ephedra-based compound, and about 200mg of caffeine within 2-hours prior to exercise, will enhance fat burning, without many of the negative side effects associated with higher intakes.  These side effects may include dizziness, headaches, insomnia, nervousness, blood pressure changes, and potential risk for stroke and heart attack.

It is imperative that physician’s clearance is given before taking a thermogenic aid, and to remain cognizant of the potential risks involved.  It appears that, if taken in the amounts listed above, a combination of ephedra and caffeine may aid in that “battle of the bulge”!
