Liver Enzyme Levels - Protein Consumption

[jimmybro1]

Over the past 8 weeks I got my liver function blood tests done to see the influence protein consumption had on it for myself. The first four weeks I consumed 300g protein daily and the following four weeks I consumed 250g protein daily. The sources of protein were the same and so where the other macronutrients. The sources of protein were: eggs, milk proteins, beef, chicken, fish and nuts. 

The first blood test results gave a liver enzyme level of 157 and the later 121 both outside the reference range of 30-120. So in my case a 17% drop in protein consumption gave a 23% reduction in liver enzyme levels. Other liver function results where normal throughout. 

It might not be exactly the most valid expermental method but I found the results interesting. I will continue eating 250g protein a day.

too many other variables. also what liver enzyme are you talking about? either ALT or AST (cant remember offhand) is released by damaged muscle tissue as well as by damaged liver tissue.

Ah, now I had this explained to me a while ago.

I can't quite remember the details, but I think one of the things that affects those test results is simply a high protein diet - irrespective of any liver stress. Wikipedia isn't helping me back that up though. Has anyone else heard a similar explanation?

maybe youre thinking of urea or creatinine levels which are associated with kidney function?

Could be. I know creatine does raise creatinine levels (funny that!) but I thought excess protein intake skewed another test result too. But maybe I'm wrong.

I think it is to do with the amount of enzymes required to remove the phosphate group from the protein. Not sure how correct that is, read it somewhere and can't find the source again. 

Doctor the raise in this particular enzyme is putting more stress on the liver..

It is not unusual to find raised creatine levels in body builders.

ALP is an indication of liver damage, however you have just raised an interesting issue.

I have a raised ALP that has been so for a long period. While GP is concerned (enough so to want to send me to a specialist) I am perfectly well and show no symptoms symtomatic of liver damage. It would seen more likely that this is related to protein intake if what you are saying is correct.

It cost me $10.000 in private consultations with Imigration New Zealand specialists back in 2008 to prove a high protein diet, creatine supplementation and consistant heavy weight training show elevated levels of creatinine and ALT...

Not AIDS, not liver desease, not hepititis B or C....

Just food and regular training...
