P.S. I always pack loads, sure you can carry less by knowing more and all that but I don't want to. i'm on a quest to bring choice to the masses with their kit. If you want to carry more, go for it, it's not a bad thing or some sort of taboo.
It's choice, i can quite happily carry my bergen fully loaded for miles and miles without it bothering me, sure I could travel a little faster with a lighter pack but i'm not in a race usually.
I'm all for more kit personally, I like kit.
In a true survival situation it could be one of your most useful assets!Abbe Osram said:I think the easily most underestimated and useless weight is the bush-crafters own body fat.
I got nearly 100 kg on the scale at one point and thought how stupid the whole thing is to carry the whole lot around hurting my knees. Its funny to see how sometimes people would choose one item over the other because it has 200 gram more weight but themselves they dont count in at all, the body fat they could spare. I got down to 85 in the first round and saved in that way 15 kg,which I dont have to carry all day around. Now.. after I stopped going my trap line I got up again to 89 kg.
But my plan is to get down to 80 kg as a standard and that would save me 20 kg I would not need to carry around all day.

The more important factor is body strength and flexibility.
If you really want to lose weight take an axe to the computer and walk out the door
What can I do... without?

I think there is a difference between survival situation and fitness. I don't say it is right to be overweightAbbe Osram said:I am doubtful if the human body fat is of any use at all, maybe if you fall into cold water but in getting you out of a survival situation I would be interested to see a test made between a group of heavily overweight people and a group of lean, light and fast moving guys. I was reading that the apache Indians could run through the wilderness 60 to 70 miles a day. These people where living from the land and wilderness indefinitely. See the pictures none of them is fat.
It would be very interesting to study if the human body fat actually has any usefulness in a survival situation at all. Lets think that we have two Bushcrafters A and B and lets assume both are equal but B´s body weight is 95 while that of his buddy A is 75. They will walk 100 km, rest for a day and walk again 100 km. Both have a backpack of 20 kg.
A will carry on his 100 km walk 95 kg forward through the wilderness
B will carry on his 100 km walk 115 kg forward through the wilderness
A will carry on his resting day while performing the daily duties like cooking or going to the toilette only 75 kg and B will have to carry 95 kg. I dont know how the counting would be if
Bushcrafter B would sleep and let Bushcrafter A do all the work, maybe than he would save energy but otherwise the fat Bushcrafter must use up more energy than his buddy A.
Understand me right here my friends I am not picking on fat bushcrafters I am myself overweight with a heavy 90 kg burden, .....today.![]()

Lets get down to basics. What follows is something that if you have not heard it before, you will hear it time and again so get used to it. It is called the rule of 3s. You can live 3 minutes without air, 3 hours with out shelter, 3 days without water and 3 weeks without food, unless you have a large supply of survival muscle (FAT) in which case you can probably make it for 6 weeks or more (One more hamburger please!)
I guess for most bushcrafters it is a weekend recreational event and avoiding obesity and remaining fit and 'healthy' is more important and being prepared for the survival situation.3.3. Evidence for the first postulate of the model: Survival time in relation to body composition
There is ample evidence to support the first postulate of the model; that obesity increases survival time during starvation uncomplicated by disease. For example, obesity in both mice and humans can prolong survival time several-fold (Table 3). The remarkable obese subject studied by STUART and FLEMING (1973) had an initial body weight of 207 kg, but after successfully starving for 382 days (no energy intake) he achieved a final weight of 81.6 kg and entered the Guinness Book of Records as the subject undergoing the longest 'total' fast. In 1966, THOMSON and his colleagues (Table 2) reported two other obese subjects who fasted 200-300 days, and several other authors have reported fasts in obese subjects which lasted between 100-200 days. In contrast, the reported survival time in lean subjects is less than 80 days. Nine of the 10 Northern Ireland festers (members of the Independent Republican Army), who died of starvation between May and August 1981, survived between 57-73 days (these results have been compiled from various newspaper reports). The remaining subject died after only 45 days of starvation but he had a prior gunshot wound, emphasising the important interaction between injury and starvation.
Various famine studies have also repeatedly noted that women withstand semi-starvation better than men (KEYS et al., 1950), and this can again be explained by the larger initial percent body fat in women.

Moonraker said:I think there is a difference between survival situation and fitness. I don't say it is right to be overweightBut that perhaps in a survival situation carrying an extra energy store (i.e. fat) will aid your survival. I am not talking obese totally unfit but in this type of situation you are aiming to conserve energy by moving around as much as possible or not venturing from the site of an accident for example.
If you had two people in a survival situation, assuming they had a source of water then the fatter guy would have the larger built in energy reserves and last longer. So for instance from:
http://www.survival.com/steve2.htm
Consider that a very basic human (and animal) survival instinct is to eat! Also it depends a lot on the sort of activities you would undertake.
If your survival depended on chasing wild animals in order to catch and eat them then being overweight would be a disadvantage. But if you had a plentiful supply of carbohydrate (such as cassava in the rainforest for instance) you could harvest from your immediate surroundings then it would be less important.
The reason why most of the people were not fat is because they used up a lot of energy in producing their food unlike us who just walks from the car to the supermarket and pays for it
I think in your scenario the fat walker would gradually use up his fat reserves and convert that into energy whilst the skinny guy will need to find the equivalent energy from elsewhere?
If you talk about two situations where body fat can help you survive, one is immersion in water and the other related to this in hypothermia i.e. the insulating properties of the fat.
There is an interesting web page which looks scientifically on body weight and survival under starvation situations. Basically a lean man of 70kg will burn 1,500kcal/day and last 64 days. An obese man of 140kg burns 2,000 - 2,500 kcal/day and lasts for 242-302 days.

I think in your test the mental strengths of the individuals regardless of weight would count for more in the end.

I agree with all of that, although I would add that exercising on fat alone is extremely impractical. Pure fat, eg butter (well 90%) has the highest energy to weight ratio, yielding 9kcal/gram as opposed to carbs and protein which are both about 4kcal/gram. But if you look at expedition rations, although they do have a lot of fat to keep the weight down, it is nowhere near 100% and at max. is likely to be little more than 60%. This is because fat is hell to break down in exercise - ask a marathon runner what it's like after the "wall". Although a fat person may survive longer, they will find it extremely hard to do any exercise after the 64 days or however long the thin person dies, as they will have no glycogen stores. This is fine if they're going to be rescued, but if they have to get themselves any distance they're at a distinct disadvantage, even disregarding the fact that they're lumping around extra weight.Moonraker said:I think there is a difference between survival situation and fitness.
