The Claim

A daily protein intake of 0.59 g/kg from egg protein leads to cumulative negative nitrogen balance and significant loss of total body potassium-40 in healthy young men over 50–89 days, indicating insufficiency for long-term nitrogen balance and maintenance of total body potassium.

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.

Cause and effect

In plain English

Eating just 0.59 grams of egg protein per kilogram of body weight every day isn't enough to keep your body in good balance over time—it can cause your body to lose muscle and potassium, even if you're young and healthy.

See the scientific wording

A daily protein intake of 0.59 g/kg from egg protein is insufficient for long-term nitrogen balance and maintenance of total body potassium in healthy young men, as evidenced by cumulative negative nitrogen balance and significant loss of total body 40K in four of six subjects over 50–89 days.

What the research says

1 study
  1. Study: 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.

    This study found that eating just enough egg protein to meet the old government recommendation wasn't enough to keep healthy young men's bodies in balance — they started losing muscle and potassium over time. So yes, that amount is too low.
