In a survival situation, what are your sustenance needs while you await rescue and/or begin to address those needs other ways.
What if it takes you a week to get a result trapping or fishing or snaring. Is there a small 'sustenance' item that you can keep with you, that will act to keep the parts of you going that you need to continue to survive?

You could make it a week without eating anything. You'd be weak, probably suffering from a bad headache and fatigued (depending on the amount of fat on your body). But you'd live.
You'd die of dehydration and exposure long before you'd die of starvation.
Rule of 3's, dood:
3 minutes without air
3 hours without shelter
3 days without water
3 weeks without food
3 months without hope
Once your body goes into ketosis (I think that's the proper term for starvation mode) it begins feeding on fat stores, and some muscle. To keep muscle from being used you need protein.
Carbohydrates give you energy. Sugars go back into your blood and are stored by your pancreas to use when the level in the blood is low. Fats are burned for energy. Sodium is salt. A lot of processed foods is loaded with sodium to presevere it (think of it as a form of salt curing).
Water is used to aid in digestion of anything you eat. Anything high in fiber is harder for your body to digest and needs more water. Sodium/salt draws moisture out of anything, so anything high in sodium/salt will require more water and draw more out of your body-thus dehydrating you at a faster rate.
What are your sustenance needs if you're lost and have to rely on a food to save you?
Easy to digest.
Not killed in Sodium.
Protein for muscle.
Carbs for energy.
Fats for fuel.
Some sugar for the blood and such.
I always carry some Smucker's Natural Peanut Butter.
No water wasted to prepare it.
Dip your finger in it if you don't have anything else.
Makes a good trap bait.
Doesn't take up a lot of room.
The only down side is that you have to swish a little water around your mouth to get the peanut butter stickiness out of it.
