Is there anything to worry about?
Yes there is. In fact, if you abuse the use of fat burners then there is certainly a lot to be worried about. You would be preparing yourself for side-effects which could be short-term, long-term, reversible or irreversible. Sounds horrifying? It is intended to be so because unless you use these things under proper guidance of an expert or medical practitioner, you are making a good case of what not to do. There have been cases in the past when people go to extremes in their desperation and suffer from side-effects. It is generally not the product that has to be blamed but the greed of the user for overnight success.
A: When protein is digested it is broken down into amino acids. The amino acids that are converted to blood sugar leave behind waste in the form of ammonia, uric acid and urea. Naturally ammonia build-up would be deadly and does occur. Uric acid and ammonia both are highly toxic to kidneys. Urea is the major metabolic fate of these waste compounds and it excreted from the body in urine. Normal urea excretion in a 24 hour period is 6-17 grams. Many high protein diets can push urea waste into the 40 gram range but has not been shown to have an adverse effect upon the kidneys during the common periods high protein diets are maintained. HumaPro® is 100% predigested providing the corrected EAA and Semi-Essential ratios for only 1% waste as compared to most proteins being 68-84% waste.
