So I did a quick number crunch on this: To get to about 75kg of protein per day, let's say you only eat lean turkey and drink protein shakes, you'd need 200kg of turkey and 200L of protein shake.
You could probably make this intake more efficient, but however it goes in, I don't think my body would like me eating 370,000 calories per day.
They might be referencing the rough math for daily protein consumption. It works out to about 1 gram of protein per pound of body weight for men and half a gram per pound for women.
A gram per pound is overshooting it quite a bit unless you're a vegan not minding your protein quality intake. The maximum effective protein intake is ~1.6g/kg (0.72g/lbs), more than that will just go to "waste" (energy/energy storage). If you're steroids the limit is higher, but there's currently no exact number on it.
