Consistently eating very little
Hi, my name is Jack and I'm 19 years old and live in The Netherlands. As long as I can remember I've been on the thin side (not upto to the point where it's actually unhealthy, imho) and a very small eater. As it is right now, I'm roughly 137 lbs (62 kg) and 6'3''(1.87 m).
When I compare what I eat, how much I eat and how fast I eat to other people my age I seem to eat way, way less than they do. I don't know why, I certainly do not have an eating disorder, it's just always been like that. If I eat a lot I tend to feel bloated and/or get heartburn very fast and really, it's starting to **** me off.
Even when I live for weeks on nothing but protein and fat I can not seem to gain any weight at all, I've been at the same weight for roughly 3 years now. (Spare me the boohoo you can eat all you want comments, I don't complain about people overeating and gaining weight either.)
Is there any way to 'learn' how to eat more food?
