Default Can a low carb/high protein diet cause elevated liver enzymes?

My husband has been on the RFL diet for the past three weeks. He just wanted to lose about 15lbs and then move into a more moderate diet. He did well with losing the weight but I think there might have been some consequences along with the diet.

About a week ago, he went to get some tests done (Echo, LFT, KFT, etc). His doctor called him a few days ago with high liver readings (both AST & ALT).

I got a little nervous hearing the results, so I told the doctor that he was on a low carb/high protein diet and also mentioned some of the supplements he was taking. She said the best thing to do now is to recheck the liver labs off the diet and supplements at the next visit.

Quick note: 36 years old, Weight: 175lbs, 19% BF, does not drink any alcohol, and does not smoke. He did not use EC either. Just took the basic supplements.

Any idea if the diet or supplements could have promoted this?

Thanks in advance.

I think there was a thread about this once before and the conclusion was that the elevated liver enzymes were a result of the strain on the liver during weight loss... I could be remembering completely wrong though... Best to do a search.

here we go: http://forums.lylemcdonald.com/showt...=liver+enzymes
that's the thread i was thinking of

High protein and/or routinely weight lifting intensely could lead to elevated liver enzymes. If that was the case it should be fine.

I did forget to mention that he does not perform any kind of training (unfortunately).

Is there a guidance to how much protein one should consume under these circumstances?

Gluconeogenesis occurs in the liver..on a crash diet like RFL the liver is put under enormous strain i.e digesting all that protein, making what ever little glucose needed out of protein and fat.

Those liver enzymes are one of the signs of liver damage..usually it resolves in 2-3 weeks when liver is put to rest(stopping alcohol,or a hepatotoxic drug, in your husbands case adding carbs back)..

Thank you for your reply Natural. He started adding carbs back after speaking with the doctor. His next visit to get retested is in about 3 weeks, so we hope it will improve his liver condition.
