Never shop when you are hunger. Most importantly though is shop ON THE OUTSIDE TRACK. The center isles are packed full of processed foods which normally carry the most calories, chemicals, fillers, etc. Using a TRACK & FIELD term, do your warm-up laps around the outside where you will find the fresh meats, fish, poultry, vegetables, and fruits. You will find that you will cut down drastically on the processed products with very little effort because once you fill your grocery cart with these items and your food budget will not allow for what I call the JUNK or Processed foods.
