Constantly catching colds?

Hello all!

I am eating normally - healthier than I have in about 2 years - but I feel like I'm catching colds now more than ever? Also, when I have a cold I get constantly hungry, even if I ate 20 minutes beforehand - does this happen to anyone else?

For the past 3 weeks I've felt like I was always catching a cold - I was constantly tired and run down and ready to go to sleep by 7.30pm (normally I'm not even remotely tired until 11.45). I would understand why this is happening if I were a) still eating below 800cals or b) it was winter. Since neither a nor b are correct, and I have been eating a healthy amount and have gained 3 pounds minumum (though I am far to afraid to check the scale recently) give or take some of it is muscle due to me finally being able to participate in dance without having a random relative pop in or what not, as well as gym class. So, it baffles me as to why I keep getting colds when I am probably healthier than a year ago, and as to why I am constantly hungry (eating good healthy fiber and protein filling foods at about 6 ''small-med'' meals a day and gaining) with a cold.

what is your current weight?

What is your fat intake and total calories?

I'm at 2,000 cals and working my way up to get to the 3,500 - even though i am gaining on 2,000 and I dont think its mere water weight, but thats what i am suppose to get up to apparently. I have around 30 grams of fat a day, at least?My current weight is, though i am too afraid to look at the scale, is probably around 85-86 at 5ft. While, yes this is still underweight and I should not be surprised that I feel constantly like I am catching a cold when I was 80pds and going off 500cals a day I dont ever recall getting sick so often - and on the few times I was sick, I was never hungry. (sorry for the late reply ><)
