    I know it is technically not a food - but how about gum? Especially the way I chew it (pretty intensely and probably not too attractively) - I'm fairly sure I'm burning some calories - LOL.

    But do you log it as exercise calories?

    I'm sure my friends would disown me:

    Nutmegoreo burned 5 calories -including gum chewing, vigorous

    Okay, I actually laughed out loud at this.

    It probably depends what you define as "food". If you ate a piece of tree bark you would get pretty close to zero calories out of it, and it would definitely burn some energy to break it down and expel it. But why would you be eating it?

    Mostly I think we define "food" as something we can get usable energy from. It's like saying "is there any fuel you could put in a fire that wouldn't produce any heat?" There are lots of things you can put in a fire that won't produce heat, such as rocks or teaspoons, but none of these things would count as "fuel" and you would have to ask why you were doing it in the first place. Even necessary zero-calorie nutrients, like water, salt, calcium, vitamin C, are not usually called "food" in their own right.

    Good to know that if I go big or go home, I can keep at least a few of my friends who are impressionable :laugh:
