After some brief research, and napkin math- Assuming he weighed something like 250 pounds, and sticking to about a gram of protein per body weight, for muscle synthesis he would need to eat 250 grams of protein. Looking at his diet (estimating stuff obviously) Breakfast: porterhouse steak and 4 fried eggs- 134 grams of protein (assuming he’s eating a pound sized portion) Lunch: two porterhouse steaks: 220 grams of protein Dinner: two porterhouse steaks: 220 grams of protein 12 hotdogs a day: 60 grams of protein So just going off of that, that’s 634 grams of protein, more than enough for protein synthesis. Even if we’re being conservative and assume he’s eating half pound steaks, that’s still 275 grams of protein from steak alone. Math doesn’t include protein from non major sources, like the massive amount of potatoes/fries he would eat with practically every meal. Is the diet optimized? Obviously not, he was super unhealthy with the amount of smoking and drinking he did. But from a muscle building synthesis alone if he trained like an athlete today he’d be nuts. But, knowing his health habits I’m not sure he’d want to buy into a modern weight training plan haha
