I just don't understand it. I'm a competitive college athlete, running the highest mileage of my life, and trying so hard to eat healthy all the time, and yet I just don't have the lean body type that runners normally do and am considerably over my racing weight. I'm female, 5'10", about 139lbs, and always felt that I ran best when I was around 130 or below, but no matter what I do my body seems to be unwilling to let go of the extra weight. It just doesn't make sense to me when I look around and see teammates who eat anything and everything in sight and yet can't GAIN weight, while I'm here running more mileage, eating less, putting a lot of effort into eating healthy, and still can't get down to racing weight. Or much less, seeing all these non-athlete college students who eat like crap, do very little to no exercise, and overall do not live in a health-conscious way at all, and yet never put on weight. And here I am running 65 miles a week, lifting weights regularly, and striving to eat healthy all the time! I've heard it said on here before that it should be very difficult to put on weight at this mileage level, but I have to work so hard just to maintain and am pretty sure I'd gain weight quickly if I ate what I wanted to. Do I just have a slow metabolism/bad genetics? How is this possible, and is there anything I can do about it?
Oh and just to be clear, I definitely do NOT have an eating disorder or any sort of history with eating issues; believe me, I love food too much;) I just know that at my current weight I could drop several pounds and run better for it, but this is seeming more and more impossible to do.
