Nurses tend to have terrible diets which is the main culprit of weight gain. I see all the high calorie sweets and fast food they eat and choose NOT to eat it. Bring your own food or eat healthy snacks throughout the day. I usually snack on carrots, greek yogurt, oranges, boiled eggs, edamame, string cheese, crackers, and nuts. Once you been eating healthy food for a while, u don't even want junk food anymore.
