What A Waste

[satchboogie]

mmm... very interesting but i'm not yet convinced.

i'll bump for some experts' opinions.

I like using 2 tablespoons EFA's (about 24g of essential fats) in all my shakes (2 a day usually). But I do use lactose free milk, or I'd have a serious protein blast out my ass

protein and fat together good
protein and carbs together good

Limit amounts of carbs and fats together.

Protein can not be absorbed without the presense of fat. Without fat, most of the protein will just be converted to glucose in minutes, so that suposedly super anabolic cocktail you think you're drinking is little more than a blast of sugar.

Please post your sources for this information.

Protein (in the form of amino acids and polypeptides) is perfectly capable of crossing the intestinal barrier without the presence of fat.

Once in the bloodstream and tissue cells, protein can be converted to sugar, if blood sugar is low. (Anyone can do a google search with the keywords "deamination" and "gluconeogenesis" for more info.) However, if there is ample blood sugar, why would the body want to convert amino acids to glucose via an inefficient-at-best process? This would upset the blood-sugar homeostasis the body tries to maintain.

If your claim was correct, even orally administered amino acids such as L-Tryptophan, which has a mountain of evidence regarding its efficacy, would never even work, as they would be "converted to glucose in minutes".


If you can produce valid sources for your claims, I will gladly stand corrected. As of now though, I respectfullly disagree with you.

I don't disagree with your whole post but I will say that I believe it is chemically impossible for proteins (made up of amino acids) to be converted into glucose (a carbohydrate). They are entirely different classes of compounds.

This process does exist in the body. Per my above post, just do a search on "deamination" and "gluconeogenesis". Basically, the amine-group is stripped from the amino acid molecule, and the remaining structure is converted to glucose.

Still though, this isn't a 'cost-effective' process, and the body will not use it unless absolutely necessary.

I also have never read anywhere that protein absorbtion in lipid dependant. Where are you getting this information?

mabye instead of milk i will just eat some peanut butter yum

DOH! I stand corrected . Brain Fart!! I forgot about gluconeogenesis.

Amen Nelson--exactly--when i was younger i had to learn the hard way--much money spent on protein but i mixed it with water and it had absolutely no effect at all--no weight no strength--then a guy said i was an idiot for mixing it with water si i tried whole milk and boom more weight and more growth......nelsons right on this one

Nelson, from your previous posts you seem to be very knowledgeable and I mean no disrespect, but my understanding of protein metabolism is that protein will be utilized if needed in the absence of lipids. Amino acids must first be broken into acetyl co A from where they can be modified into glucose via gluconeogenesis as fogg88 stated, but this will occur in case of energy deficit and is not the preferred metabolic pathway.
