The Claim

Increasing protein intake from 0.59 g/kg/day to 1.5 g/kg/day from skim milk powder rapidly normalized elevated serum AST and ALT levels in young men, suggesting liver stress may be an early indicator of protein insufficiency.

Source: Human protein requirements: a long-term metabolic nitrogen balance study in young men to evaulate the 1973 FAO/WHO safe level of egg protein intake.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

Cause and effect
1 study reviewed
In plain English

When young men drank more skim milk powder to get more protein, their liver enzyme levels went back to normal quickly—this might mean that not getting enough protein can stress your liver early on.

    When these young men ate too little protein, their liver showed signs of stress, but when they ate more protein from milk powder, their liver stress went away — suggesting low protein might be the cause.
