Gaining weight, is it purely about the number of kcals?

Hi,

I have been browsing on some website and it seems if someone wants to gain 1lb per week, he/she needs to eat 500 kcal above his/her TDEE. Do you think it's as simple as that? Is there any morphology factor?

Some people eat like horses and never gain weight....
