I am not very fit, but I do walk a lot. However when I go up 3 flights of stairs I am out of breath. How come?

In a word: gravity. It is a strong force and the reason why we don’t have flying cars yet. Yeah, F—- you too, gravity.
In order to go up an incline, it requires our muscles to generate force to overcome gravity, which just doesn’t want to let go of us. Generating more force requires more energy, which builds up more fatigue quicker.
If you want to improve your body’s resistance to fatigue, you should do this more. You will feel better for it.
Everyone is right that on the flat you are matching the force of gravity, and on the hill you are doing that PLUS more to climb.
But theres probably another part here thats more human.. People have a weird habit of holding their breath while climbing stairs. I think its probably a concentration thing. So you are probably not getting any air to power your muscles while climbing them.

When you go upstairs you are converting the chemical energy of your body into potential energy. If you are 100kg, and each flight is about 3.3333m then you are increasing your potential energy by 10kJ. Your body is only about 25% efficient in energy conversion, so you are actually consuming around 40kJ (about enough energy to increase 4l of water 10C).
