I am still having challenges with the days I have a treat/free meal as it sets me off on a quest to eat all the things I can't/choose not to eat during the rest of the week.
Interestingly, I don't overeat chocolate or icecream on my higher calorie days because I have it every day of the week.
I have now started incorporating my 'trigger' foods into my daily eating plan to de-sensitize me to their effects. I have swapped out my oat wrap for real bread [Wonder Performance Wholegrain which has 9.5g protein in 2 slices] and I am having a small packet (45g) of red rock deli honey soy chips every night. Both of these yummy treats have a low sugar content to prevent sugar overdose!
