A demand for the average American to eat more meat would have to explain, as a baseline, why our already positive trend in meat consumption isn't yielding positive outcomes. There are potential explanations (you could argue increased processing offsets the purported benefits, for example), but those are left unstated by the website.

All of the protein recommendations I've seen were for lean mass. You don't feed fat.
1.2g/kg * 90kg (~200lbs-lean) = 108g of protein.
each person, on average, in the US would be eating one 16oz steak or 3-5 hamburgers every day.
"high scores: braised eye-of-round steak 40.62; broiled t-bone steak (porterhouse) 32.11; grilled lean steak 31.0 " numbers are grams per hundred grams or wiki also reports 25% as the average, thus your factor of 2 error in weight (400 instead of 200).
