Maximuscle. Noob ?.

Jeff I really can't see where you're going with this. What point are you trying to make? Please correct me if i'm wrong but i get the feeling that you don't fully understand deamination. If i am wrong then please could you explain your point of view fully and stop with this drip feeding of information which IMHO you're doing to make yourself appear more knowledgeable on the subject than you really are. I'll lay my cards on the table and say I know nothing more that what i have read on pages dragged up by google but if you've got some further experience that means you can teach us something then do it, enlighten us, don't frustrate us ;)

WRT to my point....

You asked me whether I concede that excess protein is turned in to glucose and/or fat. Of course i do but that was never the counter argument to my original point. My point was that protein shakes = fat is a myth. OK that's not a very clear explanation of my position so allow me to elaborate. The OP asked if he drinks a maximuscle shake and doesn't exercise will he maintain or slow the rate of his muscle loss. The classic internet answer is "my mate used protein shakes and just got fat" (See this thread for evidence ;) Mass Monster). Well if the OP had asked if I eat a cream cake everyday will i maintain my physique then common sense says no, if he asked about eating an extra bowl of pasta or rice then again the answer would be no.

Too many people think that whey protein (protein shakes) are some kind of magical foodstuff that will turn you from zero to hero in a matter of weeks. Now that's not entirely surprising considering the amount of marketing BS that gets pumped out of various companies *ahem* Maxi-muscle *ahem* but the point is that excess of calories be they from fats, carbs or protein will lead to the storage of glucose and fat. That's just the way we're made.

Furthermore.........(this is turning into a bit of an epic post ;))

We need to define "excess" protein. When planning a diet the starting point is always the total number of calories needed per day. The next step is usually to set a total number of grams of protein needed per day. I know that Jeff likes a figure of 1-1.5gms per pound body weight, while others go higher at 2gms or more. Given that protein is, as Phnom_Penh points out, 4Kcals per gram (according to the USDA National Nutrient Database) then we can estimate how much of our total daily cals will come from protein. The remaining cals can be split between fats and carbs.

Keeping this in mind, I really don't see (subject to Jeffs clarification of the topic) how any protein in the diet that isn't needed for repair can be such a controversial topic. Surely using deamination the body can just break down the aminos in to glucose and fat and burn it as fuel (leaving aside the topic of efficiency)?

I'm going to try and pre-empt your reply. I guess that you're worried that a by product of the break down of aminos is ammonia that is then converted to urea and passed out the body in the urine (you mention this in your replay to Phnom_Penh). Again i'm going to add the caveat that subject to your further explanation, it is the job of the kidneys to remove these toxins. As i've stated previously, unless you are predisposed to having kidney problems this isn't an issue.

Thanks for listening, you've been a great audience, thank you and goodnight :D ;)
 
Firstly, MTA, thanks for clearing a few things up :)

No i don't want to "appear" more knowledgable than anyone, hence why i've tried to encourage ppl do their own research.

Have a read :)

Everybody already knows that excess calories will make you fat, but thats hardly learning anybody anything new, is it? I'm just trying to point out (as was kirkster before ppl jumped on him) that guzzling protein shakes is needless when you are getting plenty of protein from solid food sources, and can contribute to increased body fat.

I've read both those articles and I offer the following opinions

Re: KarlLoren.com - This is written for people on a low carb Atkins style diet. Up to the point where the section headings "The Horror Story", "Protein Converts To Carbohydrates!" and "What to do" were used it was a nice, noob friendly explanation (complete with pronunciation suggestions :rolleyes: ) of the body's need for protein and how it deals with it. After that point its scaremongery for those trying to limit carb intake. I'm not sure what part of this article appealed to you and why you cited it as a source. If it was to further reinforce the fact that protein can be processed in to glucose then you just wasted 15mins of my life :) Once i'd seen the chemical equations laid out in detail in another link I believed it was possible.

Did you think i'd gloss over or even miss altogether this comment?

"We must eat protein, or suffer the consequences of lost muscle mass or worse, but how much protein do we need?

There have been many studies. None of them are terribly conclusive, but we have to start somewhere.

Which brings me nicely onto link number two...:D

This time a slightly more concise explanation.

http://www.feinberg.northwestern.edu/nutrition/factsheets/protein.html said:
Negative nitrogen balance may result from consumption of insufficient quantity of high biological protein, consumption of poor quality dietary protein of any quantity, or consumption of intermediate quality protein sources that are not appropriately mixed because the quantities of essential amino acids consumed will not be sufficient to support demand for synthesis of vital proteins. In addition to appropriate quantity and quality of protein consumed, sufficient energy must also be consumed to support protein metabolism or negative nitrogen balance will develop regardless of the quality or quantity of protein consumed.

So we need to make sure sufficient energy is available to power the bio-chemical processes that lead to the breakdown of proteins.

Dietary protein consumed in excess of requirements is not stored, but is deaminated followed by oxidation of the carbon skeleton through pathways of glucose or fat metabolism, or its storage as glycogen or fat, depending upon the specific amino acid and the energy balance at the time. The nitrogen waste generated is excreted in the urine as either urea or ammonia.

This links back to my comment above and my previous post. When planning a diet total daily calories are always calculated first and the contribution of any protein ingested factored into that total.

This final quote is possibly the one you're actually wanting me to read and take notice of.

The effect of exercise on protein requirements is not as much as commonly believed. Endurance athletes actually have a higher requirement than body-builders due to catabolic losses of lean body mass following aerobic exercise. Nevertheless, this increased requirement can be readily met without supplementation when the high energy intakes required by athletes are consumed. Use of amino acid supplements may actually interferes with synthesis of body protein by creating imbalances. Since amino acids compete for absorption, presentation of large quantities of free amino acids to the intestinal mucosal surface reduces the amount that can be absorbed from the available supply.

Now i've not read that study so i don't know the sample size, the details of the subjects, the time period of the study etc. and most importantly who paid for the work to be carried out ;) but i guess you haven't either. On the basis that they only reference a single study and also keeping in mind what was said in the first article, I don't find this a particularly compelling piece of evidence. Especially not when i've yet to see any negative implications to protein being used as a fuel source.

It might seem that i'm dragging this out a bit (hey its more fun that work :p ) but i'm still not sure what your point about deamination is.

Jeff your point of view is usually less blunt than Kirksters original comment that "All this protein shake stuff is ******** and it'll just make you fat/overwork your kidneys." which started this whole episode. I think most of the regulars round here would agree that you can meet all your protein requirements (and possibly more) from solid food but as has been pointed out to you before, whey is used a supplement when real life gets in the way (be it family, work, money, time) of a solid food diet. As a "user" ;o) you've got to see where we're coming from. Using words like guzzling suggests you see whey as a negative thing.

Notice i edited your post when i quoted. That addition bold (was that even needed?) statement is a half-truth as it implies that its something specific to protein. This, as we all know, is incorrect.
 
Simple fact is in my mind, whatever the specifics, that considering any food to be NOT conducive to weight gain is retarded. Its like the way a lot of people look at fruit and salads, healthy foods so no calories. Of course thats not the case, it just seems to be because its hard for someone to imagine a tomato or an apple as turning into fat, its another case of common sense contradicting knowledge.

Fact is, if your drinking shakes and not factoring those calories into a sensible program/regime then your a fool and probably will gain weight and will never be a particularly good body builder.

I still maintain that the whole 'protein shakes make you fat" thing comes from the old Weight gainer supps of the 80's and onward. They showed on the front a massive bodybuilder, ripped to shreds, but they were 1000kcal per scoop super bulkers for ectomorphs. They equally didnt make people fat per sey, they just led people to believe that there was more magic to muscle gain than hard work, calorie intake and exercise
