I'd like to share an article with you. I really enjoyed the information in here from Backpacking Light - How to go light with your food and eat well. I am averaging about 680 grams a day. This is a little higher. For the metric people (the rest of us in the world!) an ounce equals 28.35 grams - Enjoy!
