Be advised, unless you plan to run something like a marathon, fat is 9 calories/g vs protein 4 calories/g. So if the steak is as @Bricktop
posted "fat content is insane" , say 25%+ fat, a 16 oz portion is going to be close to 2400+ calories not including some sort of beverage.
Somehow I don't think that "unbuckle your belt and jeans and watch some football or porn" is going to do it.
Wagyu beef can exceed 25% fat,
