Nutritional value of body fat

Posts: 3 Member
edited November 2024 in Health and Weight Loss
A survival expert I know said if you're lost in the bush, don't bother looking for food--the average North American can survive without food for 3 months and come out in better health than when s/he went in. He said you'd increase your chances of survival by spending your time and energy looking for water and shelter and planning your rescue instead. Also, one would probably burn more calories looking for/hunting/gathering food than one would gain eating the harvest. My question is, does body fat contain any nutrients that are released when we burn it? Would we survive without food fine for 3 months as far as calories go but have problems due to vitamin and/or mineral deficiencies? Lack of protein or carbs?

    Not eating for 3 months? Somehow I don't think that's going to work out... the muscle wastage alone would have you a ragdoll.

    So are we gathering and hunting for our food here or are we fasting? I'm confused.

    I wouldn't, I get grouchy after 8 hours sometimes!

    Three months is extreme. Three weeks - yeah, doable. But three months and you're coming out a wreck....

    To answer the original question - it would have been a pretty serious design flaw if our bodies evolved an energy storage system that didn't also include storage of a few key nutrients.

    Ummmmmm, no. For the survival expert part. And these extremes (21 days) depend on proper hydration and laying still to preserve energy.

    There are some micronutrients that are only stored in fat. Vitamins A, E, D and K are stored in the fat. Fat stores convert very nicely in to the glycogen we need and if we need protein, the body will (un)happily pirate from other muscles. Hopefully not from the heart muscle.

    I believe the point was the person could survive the 3 months without eating at all, would burn more looking for food than eating it so there was no point, and would magically be better off for not eating for that whole 3 months. W.T.F.

    You know how many medical problems you'd have if you didn't eat for 3 months!?
  • Posts: 14,464 Member
    I'd think the lost North American would be better off knowing about all the edibles surrounding him or her.

    Sure.

    And as long as we're doing the hindsight thing, they'd also be better off not getting lost in the first place.

    LOL. It can happen in this part of the world, despite the best-laid plans. Let's say the bush plane crashes, for instance.

    Better health? I think not. Your body will break down your lean muscle when you aren't eating protein or any other nutrients. if your potassium levels get too low, your heart will go into arrhythmia and you will die of cardiac arrest.

    So...is this the newest diet fad?

    Survive? Yes. Thrive? No.

    Survive? Yes. Thrive? No.

    Risky to say yes, since the question is "would we survive for 3 months without food?". Depends on the starting weight and health of the person, doesn't it?

    I assume that's where the "average American" (ie, obese) bit from the OP kicks in.

    I'm going to go out on a limb and guess that he hasn't illustrated his point by doing this himself.

    Poor brain would be mush after 3 months. Who'd want to "survive" that? Better off living off sushi and Sapporo. I'm staying amongst civilization.

    This thread title honestly sounds like someone is attempting to calculate the nutrients found in human fat for the purposes of cannibalism..

    completely what I was expecting this thread to be about.

    A morbidly obese person would probably have a better chance of surviving than a skinny underweight person. Possibly??

    I'm attempting to calculate the nutritional value of human liver with fava beans and a nice Chianti. Asking for a friend....

    the Chianti is what gets you. Only 3 ounces per serving!
