Find a pic of yourself at your heaviest, put it on the fridge door to remind you why you are doing it!
Think of the benefits you will get, more energy, less medication, longer life, less aches & pains, I could go on.........
Write a weekly menu, keep a daily diary & only buy the ingredients for the meals you are having each week, remember you can have "treets" just remember to allow for the syns in your planning. I have small amounts of chocolate, measure it out with the syn value & ONLY have a portion at a time!
From time to time you can cheat & enjoy yourself, you have the rest of the week to recover!
Good luck.
