I am a 19 year old male currently attending college at a state
university. I am 6'3'' and I weigh 155 pounds. When I started college
I weighed around 165 and I was looking to gain around 20 pounds but
nothing I do has worked. I also look very pale and people often ask me
if I am sick. I get 14 meals a week at a buffet dining center that is
30 seconds from where I live and I also work there so I get another
free meal 6 days a week. I no longer regularly exercise, but I walk
around my extremely large campus for well over an hour each day going
to and from classes. No doctor has ever said anything about my low
weight even when I bring up my concern that I weigh 10 pounds less
than I did 6 months ago. Is this healthy? If not what can I do?
