Not as hard as you may think. Soft tacos for lunch would get me over 100g alone. Eggs, hamburger, protein shakes, beans, lots of things offer protein easily enough. I would generally go for 250-300g a day myself, but again, was not doing 20k/day, about half that. So makes sense. Eggs are easiest scrambled, so maybe 8 of those generally, add some bacon to that also, about 6, who am I kidding, 10 slices, lol, and toss in some toast with butter, and hash browns, that'd be fine for breakfast. You're talking probbay 75, 100g protien there. For lunch, tacos, or burgers, probably 5 1/4 lb burgers, fries and a coke, maybe 75g there, dinner a xl combo meat pizza, about 125g. All relatively easy to stomach actually. So on a average day, about 275g at least. I say that's light on the count also because there's also snacks, a bag of chips, drinks, 1/4 gallon milk, maybe a 2nd pizza, trail bar, maybe a protein shake - never really liked them. It all adds up and you just eat what your body needs. Spent way too much money eating when I was working out like that.
