Good points there and the link looks good something I'd like to learn more about I love my food!!!

I've done some nutrition at diploma level and the books I researched say the body does not store protein and cannot store protein. Protein is used for building/repair tissues like muscle etc but when there is an excess of protein it can be used for energy, thus sparing carbs the body would have used for energy and storing the carbs as fat. At least that is the way I understand it. does anyone here employ the metabolic type nutrition plan as a giude or blood type nutrition?

The muscle mags and muscle forums have a lot to answer for, the forums have a rank system were the more you post the higher rank you are and more credibility you have at least to new comers. So it really doesn't matter what you post on these forums! how can people get quality information when a forum is scoring on quantity of information? rant over! (bit of a change in direction there sorry)

I wish I could link the lecture series that my professor presented, but alas I cannot. It is true that the body cannot store free amino acids, so excess is broken down in various organs (kidney, intestine, liver). The carbon backbone is used in gluconeogenesis and the nitrogen is incorporated into urea to be excreted in the urine.

As for carb sparing, its a little complicated on that front since it becomes a carbohydrate, but I can see what you're saying since you're adding to the carbohydrate pool. The way I always hear it is that you spare glycogen, which is still a carbohydrate, but the amino acid derived glucose is adding to the labile pool, sparing the stored carbohydrate. As for the spared carbohydrate becoming fat, thats the link I wish I could provide covered.

The relevant lecture involved a study that was about 2000 nurses given a diet of about 70% carbohydrates, 10-15% protein, and the remainder fat, isocaloric to their normal diets. Over the long term their serum triglyceride levels raised slightly, but they all lost about 2-4kg. The point of that study was to show that a high carb diet would illicit weight loss versus lipogensis as typically thought with a high carbohydrate diet. The topic for that lecture was that while some carbohydrate derived lipogensis does occur, its typically very small/negligible on the scheme of weight loss. The lesson was that intake of carbohydrates stops lipolysis, causes the body to burn exogenous carbohydrates and store incoming dietary fat, which is probably why the high intake of carbohydrates (typically as HFC in the western diet) + high fat intake was contributing to the obesity epidemic. And that was entirely off topic..

On topic, the excessive amount of protein that most bodybuilding websites preach is to ensure that the body gets enough raw materials for protein synthesis. The g/lb ratio just seems to keep increasing despite the information given by dietitians and nutritional scientists that the body's natural potential for growth doesn't require that much protein. However, with steroids, I have no ground to speak on because of my inexperience in that area. For anecdotal evidence (barring individual metabolism, genetics, etc), I've been steadily gaining weight with about 1.1gprotein/kg, no supplements, modest strength routine, interval training, and maintaining 5% bf. And I don't exactly come from a lineage known for being large (chinese, dad-130lb, mom-120lb)
