A thought occured to me this morning (okay, I read about this on another site) about how to add calories to a long distance diet. How about using a body-building or weight gain supplement like you can buy from GNC, etc? I'm thinking of those cans with pictures of muscle bound models on the front that promise to bulk you up. It started me thinking about tossing a bag of this stuff in to a few resupply boxes. Has any one tried this, either while hiking or for working out?
