My1 year old's eating habits...?

I see most people asking why their child isn't eating enough. My son will eat anything put in front of him!!! He has been 25-27 pounds since he was 7 months old he is now 13 months and it hasn't gone up or down in his weight. But he will eat or munch all day long if given the opportunity. He LOVES cheetohs or the equivalent in the gerber graduates lil munchies mild chedder he loves cheese. I don't feed him anything overly bad fat filled or sweet only on occasion. But if we eating he wants to try it if he doesn't get to have a piece he throws a fit he has a regular meal schedule breakfast lunch and dinner but if I give him food he will eat it. He is very active with mobility to so I am wondering if it is just because of how active he is. Even while teething which he has two molars coming in right now I had no idea about until he bit down on my finger doesn't even seem to bother him. Is it healthy how hearty his appetite is or too much he never seems to have a tummy ache either not allergic to anything and never been sick. I am just dumbfounded and surprised by how hearty the appetite is could it be hereditary to because I have a hearty appetite as well and not picky about anything or allergic to anything.
