Depends on how much body fat you want to have. Pro body builders, just before a competitive event are carrying a very low body fat %...around 4%...not really healthy, but ripped. 10,000 calories a day, mainly protein, good fats & a modest amount of vegetables...is quite common for them. They also may consume 10,000 calories or more per day.
Now the guy in the video is not primarily concerned with body fat, but rather strength. Compared with the bodybuilder, he trains differently ...usually lower reps and higher pounds per exercise. Compared with the bodybuilder he eats way more carbs...hence the greater % of body fat. I'd estimate he's carrying about 15-18% body fat. I prefer to be around 10%...not really ripped but no beer belly or love handles.
P.S. Not all bodybuilding contests, especially the lower level ones, permit steroids...and they test entrants.
