"You aren't a dog--don't reward yourself with food"
A great quote that I recently read and this may be one of the main reasons many people fall off the weight loss wagon! Why you may ask? Because you are rewarding your healthy behavior with unhealthy!! You do NOT want to enforce positive behavior with negative treats! By all means if you want to have a "cheat" have it but only have one serving! This way you will never feel deprived or encouraged to eat those unhealthy foods.
For weight loss success positive rewards for me are:
-I allow myself to get some new clothes -I take a bubble bath -Read a book I've been wanting to read -relax without any interruptions! Things like that are very helpful for me!
