I have lost 2 pounds

I have been on mfp probably years on and off and never took it serious how can I lose weight while still eating crisps every night! ( i love crisps) I have stuck to my goal and weighed everything properly I am soo happy right now to even lose 2 pounds as I have struggled with every other diet it just goes to show cico works I am going to stick with it this time I only need to lose 30 pounds I am 5'4 I am so impatient but I didnt put this weight on overnight so thankyou to all the posts I have read to keep people going! I feel now I shouldnt class "crisps" as a bad food and eat everything in moderation so thankyou everyone for the posts I have been reading to stick at it!!! Xx
