Plan ahead by bringing really good choices. It doesn't take a lot of effort or planing to swing by the grocery store and pick up these 6 items:
1) Bag of organic apples - I love Pink Lady, Fuji, or Honey Crisp
2) Bunch of bananas
3) Bag of baby carrots
4) An orange
5) Bunch of grapes
6) Celery Stalks
Feel free to substitute any of the above with your favorite fruits or veggies.
Then, the next time you are feeling like you need something from the vending machine, grab your change, plunk it in your jar that you have secretly labeled "Paying myself to be thinner and happier" and enjoy whichever fruit or veggie sounds best to you. Does one make your mouth water?
