we all hear if you are fat you are out of shape ,
what if, lets say you have a 200 or 180 pound person, who eats healthy and has strenghend their body, just hasn't lost weight
you put that person in a survival situation, they are heavy, but have eaten healthy and conditioned their body
and you put a 120-130 pound person in the same situation with them, who has the same eating and excersise habits

they both have the same survival knowledge, and equipment, -If any-
lets make the situation in the mountains and its winter

who will last longer?
the person who is heavier? will the body burn through the fat before muscle ,? giving a week or more over the thinner person who doesn't have any fat on them?

will the heavier person stay warmer naturally?

who will last longer?

Heavier folks do tend to have greater resistance to cold as well as being stronger due to their larger mass. However actual traits can very greatly between to individuals of the same volume or the same weight. The heavier individual will likely last longer due to the greater amount of fuel their body can store. Of course that doesn't matter if they both freeze to death at night, as is quite likely in a winter mountain scenario.

Never been in a survival type situation like that. I have, however, been in the hospital for up to 2 weeks at a time without food. I was getting liquids via IV, but no food at all. So it might be somewhat applicable to the question?

At the halfway point, my friends were getting concerned about how I was noticeably losing mass. The body will naturally cannibalize itself - I've read that fat is "preferred" by the body (it's a higher energy storage device), but I know at the end, I had lost both muscle and fat. Since I wasn't moving, I wasn't maintaining my muscles at all, just laying in the hospital bed all day, so in a survival situation, that may be a bit different. Of course, moving would also use energy faster, so the body would cannibalize itself even more, possibly leading to even more muscle loss even with energy stored in fat tissue. By using the muscles, they should be maintained a bit better so the body would likely favor fat usage even more.

The other side, though, is that even if they have the same fitness habits, the heavier person will generally have more muscle mass to be able to move as easily as the lighter person.

The mountain aspect is the wild card. Even if both are fit, and the heavier person has more muscle mass in order to be able to move as easily, more mass does make breathing harder, so at altitude, they would be more susceptible to altitude sickness, and generally have more trouble moving around, finding food, etc.

Given all that, I'd say the heavier - but still fit - person would likely last longer. When lost in the wilds, they say the best strategy is to stay where you landed, more or less, so if both examples are staying still, the one with energy stored in fat would be able to stay still longer, more likely getting rescued.

That's a trick question since taller people can weigh more...................

...but 120-130 pounds. Hm That person couldn't be all that tall.

Sorry, should've included this.. why do you think that? I tried to include my thoughts before on why. And, I mean, if you're thinking of fat as an insulator, it's not all that great, but then again, even in the summer many mountains still have snow caps, so that would still seem to argue for the heavier person..

If they're both in decent shape, and have similar training, etc. I'd put my money on the heavier person lasting longer in a survival situation, they simply have more 'stuff' for their body to burn through before they starve.

If you took two people of about the same weight, one with more fat and the other with more muscle: the person with more fat will likely stay energetic (i.e. able to scavenge for food) for longer. The body prefers to burn fat: it's easier to break down for energy than muscle and muscle also serves a rather vital role in facilitating movement - it just isn't meant to be cannibalized for energy except in pretty dire circumstances.
