I would say the energy can be satisfied by any fuel except protein. Fat or carb, plus the necessary katalyzing enzymes and coenzymes. Of course protein also acts as fuel as glucose or pyruvate or AcetylCoA, depending on which amino acid. Many here in the list think that protein energy is even better utilizable (slower digested, most not resulting in glucose, and meat is always accompanied with some vitamins at least). But if the excretion of the split-off nitrogen part of protein is the problem of course anything more must be avoided. But that's theory. I think there are few places on earth where someone could tell the real answer by testing it. But here on the list are people who can. Many are on a ketogenic diet. Some (I recall Philip Thrift) has reported about suchalike intoxication. So if someone on a ketogenic diet would try to eat from 240g up to 300 grams of protein *whitout* much fat or carb (rabbits or other wild game), he could tell. Maybe Ray, who's eating rabbits. What happens if you eat 3 lbs of rabbit per day? Did you try? Btw: I don't think that adding fat (or carb) would help against the intoxication. It would just give more energy. Disclaimer: I don't think it's wise to try this, so please don't blame me for the effects if someone tries it. Maybe someone already *has* tried it and could tell more about. Btw: 300g or 240g protein may be a ceiling- for a healthy person. Maybe only for a trained person (with enlarged kidneys). It looks like long before this point a antipaty against more protein comes or even nausea. That was even so for the expert Stephansson (18% protein). If you recall what I said about vegetarians and meat-eaters and how they eat energy. Meat eaters can come along eating zero-protein energy (sugar), because the meat already had much protein. As far as theres a effect of nausea or antipathy to add more protein (after the 270g meat) that would even be a urge to eat zero protein energy. Increasing "my" effect. >If it can be >only satisfied using fats, then I would tend to call >it fat-hunger. I think this fat-hunger could occur independently, either in very low-fat diets or in very high fat diets, when the SFA and MUFA part is very high and so the EFA's are displaced in some functions. regards Amadeus
