Hey. I am new here, so I am not sure if I am posting this in the correct forum, but I thought you guys could help me out. I am a 18 year old female runner. I run about 50 miles a week with some cross training and weight lifting. I generally count calories and have been aiming for 2000-2200. I am 5'5'' and 112lb. and have been staying this weight on this amount of calories. However, some people have told me it is too low. So, I was wondering if I could increase my calories without gaining and if so to what amount. Thanks for any advice and sorry this is so long.
