Aha.. hier is het stukje van Lyle over de 30g /maaltijd!
Dat over de verh vet:KH staat niet in het interview maar in het hele boek plus in die voornoemde webstek van Petrizzi.
Wannabebig: So how much protein can the body use for growth?
Lyle M: In terms of supporting optimal growth, an interesting discrepancy actually occurs here between the studies on our ancestral diet and the protein needs of athletes, but nobody has an explanation yet. Good studies by Peter Lemon, Mark Tarnopolsky, etc. support a maximum protein requirement for natural lifters of about 1.8 g/kg (a little less than the 1 g/lb that bodybuilders have used for years). But studies of our ancestral diet suggest protein intakes as high as 2.5-3 g/kg. Nobody is quite sure if this protein intake was simply a side effect of the diet our ancestors followed, or if it had some actual benefit.
Finally, I think the whole 30 g/meal (or whatever) thing can't possibly apply to everyone. I mean, at the low end, figure a 210 lb lifter is eating 210 grams of protein per day. If he's limited to 30 grams/ meal, that means seven meals minimum per day. Obviously, if there is some limit to protein absorption/assimilation/digestion/utilization (and I don't honestly think that there is) it's going to be related to body mass: a larger individual needs more protein and would be able to utilize protein in larger amounts than a smaller person. Ultimately, my hunch is that the whole '30 grams per meal' (or whatever) thing came from one of two places:
Early supplement companies trying to convince lifters why their protein product (containing 30 grams) was better than others. I remember one company pulling a scheme like this, when their product contained like 37 grams of protein, they wrote that 37 grams was the maximum that could be absorbed. When they bumped it to 42 grams of protein per serving, 42 became the magic number. Ah, advertising.
Bodybuilders rationalizing what they had already decided to do. That is, you frequently see bodybuilders and other athletes finding a strategy that works (i.e. eat protein at intervals throughout the day) and then making up physiological rationalizations afterwards. It wouldn't really surprise me if that weren't the case here. Of course, if anybody has a single piece of peer-reviewed research supporting this 30 grams myth (everybody seems to claim to have seen it but nobody seems to ever have it; it's like those friend of a friend stories), they can feel free to send it to me care of
