I just don't get it

So as of today's date I have lost 18 pounds. Thursday I learn about how many inches I have lost. I feel better, I and working out, and I have not given up yet. Today I worked my ass off with the GHF and then afterward I came home and wanted to devour everything in sight. FUUUUCCCCKKK! It drives me crazy. Why on earth would I risk undoing the work of the work out. It's hard work, I push my boundaries and yet I want to eat every carb in the house. I just don't get it....
