Hi,
Wel come to HCM,
It is becoming fashion to take alcohol, what you have written is he is fit and going to Gym that is great but ,to take alcohol 2 pints on weekend is not justified so ideally he should stop completely, if possible it is definitely injurious to brain and liver also.
Both the amount and the duration of alcohol consumption are critical in the development of liver disease. Contrary to general opinion, the type of alcoholic beverage is not important. Thus, one drink (1 ounce, 30 ml) of liquor (whisky, gin, vodka) contains the same amount of
ethanol (13 grams) as one glass of wine (4 oz, 120 ml) or a can of beer (12 oz, 360 ml). There is no ‘threshold level’ of alcohol intake beyond which
liver damage must occur. Instead, there is a gradual transition of increasing liver
injury as the quantity increases
Again my advise would be stop alcohol,if not possible take in limited quantity.
Good luck to you.
