Why am I so hungry?

Ok I am trying to take a look at my eating to see where I am going wrong. I am either eating too much or not enough.

Well last night and all day today I have been very hungry. I ate my oatmeal this morning hoping that it would help my stomach but before I even got to work my tummy was rumbling for more. (This is usually what I eat..... so I am clueless!)

I had my snack and my normal lunch and then another snack for the end of the day..... and I am still hungry! I did have an intense workout yesterday (cycling class for 60 min.) and my dinner consisted of capn' crunch cereal. So that is probably why I was so hungry in the morning...... But why is it carrying on all day?

What is up with my body?!?!?!? Any ideas?
