So far it has worked; I'm down 18lbs: This misconception arises from the fact that one must undergo a period of induction into ketosis approximately days in which the body adjusts itself fully to a ketogenic metabolism. I've found your work in compiling this information enormously helpful and highly commendable. I fear that I may have already lost a little bit of muscle mass but that could be to the caloric restriction and depletion these past few days so I'm not worried. I have returned the favor.
There are plenty of fly-by-night products around(pretty much all of the ones in local stores) that only offer a very subpar purity. Often times such supplements(like ones sold at WalMart) only contain 20 or less HCA- even when they are marked as higher(this was the conclusion of a recent study). Such low-grade products(like the ones from GNC usually) are basically scams, replete with fillers and additives and dont do much to give you the true benefits of the natural extract.
One of the biggest advantages of GC is its ability to prevent carbs from becoming fatty acids once inside the body- which is a result of the HCAs effects. Remember to take the dosage that is recommended on the bottle and do not deviate from it.
