I guess it's trivial what you say about calorie deficit but the trick is how to not devour that tasty something that you know is there in your fridge when your plan to eat less for a few seconds is only your second priority.

I might be a bit extreme but I have no food in my fridge. I have flavored water (0 calories) and I drink that when I'm hungry. At noon I eat out. If I have food at home I eat too much so this is the only way that works for me :|
