I often suggest my patients use smart phone apps to help them with their diet, in particular Lose It! or MyFitnessPal. Both progams have the ability to scan a bar code of a food item, which will then show the amount of calories, protein, fat, carbohydrates, etc for a given portion size. Not having any food in my exam rooms, I grabbed the box of tissues to show how to scan the bar code. Lose It! identified it as Sesame Chicken!
Too funny :))
