What I thought too Arch. Rik: I am quite certain that any living body, human or animal builds fat reserves by consuming excess amounts of energy. Although eating plain fat off a roast may sound unsavory to some, one doesn't really get fat by directly consuming gobs of it. rather consuming more energy whether derived from plants, sugars, meat or fat and the surplus left over from daily requirements is stored as ones own body fat. Any doctors or nutritionists around to verify??
If you want to loose weight, eat less fuel than your body burns, simple really, in theory that is I read a book by Ranulph Fiennes (Sir Ranulph Twisleton-Wykeham-Fiennes, 3rd Baronet) about his Antarctic travels; his diet of pemmican (50% fat) was supplemented with extra butter, and the man still lost a dangerous amount of weight
Fat is ok, but here is a small reminder of the original topic of this thread , the virgins A colleague of mine found this unused Primus 210L when he looked through the belongings of his late father in law. My guess is that the first time it was out of it's box, was when we first opened it half a year ago. The stove is clearly marked as a Primus 210 but the observent reader will see that it looks more like an Optimus 00, including the threaded pump knob for the blinding cap. This tells me that the stove must have been made in 1962, or one of the following years. That year Optimus acquired the rights to produce and market the stoves under the Primus trademark from Bahco. Over a period of some years, Optimus made an "Optimus 00" marked and sold as Primus 210. As can be seen on this photo the stove was originaly priced $19.50 My colleague's father in law had a brother that emigrated from Norway to USA. This brother used to buy presents and send to his family in Norway. The price tag indicates that this stove most likely is one of these gifts. It's a nice stove. It has never been lit, and will probably never be. My colleague still has his hands on the stove, but I know on which shelf in his office it can be found 8)
When are you gonna flame it Arch?????? he he As for fat, I've never met a nutritionist who says we sould not eat fat. What's the debate all about? Regards, Alan
I would keep the box, the tin and the rest untouched, but the stove needs to fulfill its design criteria and be lit
This is an interesting read I found online "Many wild animals, especially small mammals have so little body fat that reliance solely on their meat for sustenance results in 'Rabbit starvation', a potentially fatal condition brought about by consuming a diet consisting almost entirely of protein. The most common historical example has been those attempting to rely entirely on rabbit meat. Rabbits are one of the easiest animals to trap and it is easy for someone who is catching large numbers of rabbits to assume that they are providing themselves with all the calories their body requires; but this is not the case. A person who eats nothing but rabbit meat will begin to experience headaches, fatigue, and discomfort. If they continue to consume nothing but rabbit their stomachs become distended and after a week they develop diarrhea, but no matter how much they eat they will be unable to satisfy their hunger, eventually they appear to starve to death even whilst continuing to consume large quantities of rabbit meat. This happens because rabbits have very little body fat, so the calories provided by their meat are almost entirely in the form of protein. For protein amino acids to be used as fuel they have to be converted into glucose by the liver in a process called gluconeogenesis, this metabolic process requires a large amount of energy in the form of adenosinetriphosphate (ATP). Six ATP molecules are used to convert the amino acids to glucose and a further four are required to convert the harmful Ammonia which is produced as a by product, into urea. The liver relies solely on aerobic metabolism to replace the ATP molecules that have been consumed. The liver obtains around 80% of its oxygen from the portal vein which because of its venous nature has a low oxygen partial pressure; this scarcity of oxygen limits production of ATP, thus limiting the production of glucose from amino acids. By determining the maximal rate of urea synthesis and therefore the point at which glucose production ceases, it has been calculated that the maximum capacity of the liver to produce glucose from amino acids in an 80kg individual is restricted to approximately 250 grams a day (1000cal), not nearly enough to support an active person. However this limitation of available calories is not sole cause of the symptoms described in those who have suffered and ultimately died from a protein exclusive diet, the true cause of the deaths resulting from this condition is far more insidious! The liver begins the process of turning protein amino acids into glucose by removing the A-amino group made up of nitrogen molecules (ammonia) from the amino acids so that the remaining carbon skeleton can be utilized, this ammonia is highly toxic so under normal circumstances the ammonia is immediately converted into urea which can be safely removed by the kidneys. however if the livers ATP supply is exhausted due to a lack of available oxygen it cannot convert the toxic ammonia into urea and is forced instead to release the ammonia into the bloodstream. The phenomenon of rabbit poisoning can now be explained as follows, an 80 kg person subsisting exclusively on protein can only provide their body with a maximum of 1,000 calories a day, because their liver is only capable of producing 250 grams of glucose from protein via gluconeogenesis regardless of how much protein they consume. Because of this lack of calories the individual is unable to satisfy their hunger through protein alone, but in a desperate attempt to ease their hunger with the only food source available to them they continue to consume protein unaware that the liver, unable to complete its breakdown of the amino acids into glucose due to a lack of oxygen is releasing highly toxic ammonia into the blood and the more protein they consume beyond the initial 250grams per day the more ammonia is building up in their blood where it damages the central nervous system. This damage manifests itself progressively as irritability, headaches, vomiting, somnolence, coma, and finally death as a result of cerebral edema. In summary, no matter how much protein you consume if you only eat protein you can only provide yourself with a maximum of 1,000 calories a day, the remaining calories must be provided in the form of fats and/or carbohydrates. If you attempt to consume more than 250 grams of protein a day in a diet consisting exclusively of protein you are simply poisoning yourself with ammonia and hastening your demise. - copyright 2006 Stuart P.

I Do not think you shoud light any of the virgins, Like spudz said ,"buy a used one the same ", I bought a unused Optimus 8R 1971 model still in it's box, ( I also like the big old style control knob), And I was thinking of using it, Then I saw a beat up old 8R on Ebay ,and bought that as well, And had a ball restoring my first campstove . OK, one more thing, if anyone knows where I can view, or downdoad a copy of instructions for a OPTIMUS 22 the Kerosene (Paraffin) model
Rik, interesting food reading. I attended a presentation by these people who spoke about a very long trip they did through Quebec. During the trip they ran out of food and had to hunt game. They generally were able to shoot birds, I believe it was Ptarmigans. They were able to eat enough to not be hungry, but they were slowly starving their bodies and came close to dying from starvation. They were able to get plenty of calories, but not calories with the proper balance to maintain their bodies. Each day they ate their fill and yet were slowly dying from starvation. Back to virgin stoves. I used to be of the mindset to light the stoves. Upon further contemplation, I've changed my mind to leaving the virgins alone, and use the ones that have some experience. Certainly easier in my limited exeperience.
Your right Alan, an interesting read. Your body does not make a lot in the way of fat, it tends to store fat from what you eat (vegans make more I believe?) I was in a biology lecture a couple of years ago, and the lecturer there said that an autopsy will show up your favorite meat in the fat stored in your body, chicken, beef, lamb fat etc
The rabbit/protein-thing Rik describes, here in the Netherlands was a widespread problem in then poorer parts of the country (e.g. sandy grounds in the south and east) before WW II, where wild rabbits were abundant and free for all - whilst cows, pigs and other fatty meat suppliers definitely were not.
