Ive lost weight and am now skinny everywhere (even my shoulders) EXCEPT MY STOMACH!?

i think the reason i am not losing the last 2-3 kgs of fat thats left on my stomach is cos i kept breaking my diet with binges and this is the time where my diet needs to be extremely calculated in order to work? what do you think? ive made it very strict now to see the final results any tips that will help this process or maybe any advice
