I just wanted to add something about the treats.
I used to be of the same mindset as dietnlose. At the start of my lifestyle change, I simply could not trust myself to buy a bag of hershey's kisses and not eat them all at once.
That has since changed. At first I cut all treats out of my diet but slowly let them back in and now I have willpower.
There has been a large bag of Peanut M&M's in my fridge for 4 days now and I have yet to open them.
I still have some York Peppermint Patties in my candy bowl that I bought a month ago.
You can do it. Maybe not at first as temptation may be too great but eventually you'll be able to have treats and enjoy them for what they are, treats
