You could get the frame and size from it, and I’m saying this as someone who’s met Jeff, and he’s honestly not as big as it might seem online (lighting is better than roids for fitness content creators), but the leanness is what’s gonna be hard.
You could get lean enough to reach single digit fat percentages, but you’d end up looking very flat, as we cannot have our glycogen storage filled up naturally while on a caloric deficit, especially when trying to get that low in body fat.
