Leaving high school I was 6'5" and about 170. I also have always had a very high metabolism. At my biggest I have been 250 and 11% body fat. I have trained my body to accept more food over time. I would struggle to pack in the macros and force myself to eat, to the point of nausea. This is exactly what you are going to have to do. Just watch closely as you are learning more about your body to ensure you don't turn into a fat ass.
