You got guys that are both 5'10" 130 lbs. They both have the same exact genetic capacity.
One guy eats steak, eggs, chicken all day friggin long. Will eat junk every now and then, but keeps downing that protein. He drinks his water He gets his 1.5g/lb + per day. Only problem is he will not stimulate his muscles. He doesn't work out.
Then you got his twin who works out like a beast. Squats, deadlifts, rows, bench press, repeat. But he will eat his typical American diet. Might get about 100 g of protein for the day max.
Now a year from now, they meet each other. Who got bigger?
