I wasn't sure if this topic belonged in long-term or just survival so I stuck it in survival. I was hoping to stir thoughts about this subject not only in regards to wilderness survival but also normal emergency food storage. People often don't have enough calories in their piles of canned foods.

Yes, most of us have emergency fat reserves convinently tucked away in not-so-secret compartments in our bodies but as some others have already mentioned, it takes a bit for that metabolic pathway to kick in and even when it's running we are not going to be feeling or working anywhere near the top of our game. A few days without food isn't going to kill us but it'll certainly make us miserable.

Desperado, your classroom awaits your arrival!
