Why exercise annoys me

I need to do some math. Bear with me.

Breakfast:
Berries   100
Yogurt   80
Milk   120

Snack:
Banana   90

Lunch:
Cottage Cheese   90
Banana   90
Toast w/ butter   110
Veggies   30
Hummus   100

Snack:
Piece of casserole   150??
Apple   70

Total so far:   1,130

So we went for another intense hike today and I had to eat more because I was so hungry afterwards. But how many calories do you burn on a 1.5 hour hike?? Not sure if I'm actually hungry or if my brain is lying to me. I broke down and had the casserole as an extra, but I'm still hungry and if I have any thing else extra I'll be way over my intake goal eeeek. I'm going to wait 15 minutes and see what happens. I'll let you know how it goes :s
