Brand of Protein: 0 grams of carbs?

[javaguru]

When your body needs glucose it can convert it from amino acids, fats are NOT turned into glucose! A by product of fat metabolism (ketones) can be used by the brain for fuel but fats are burned directly as energy and cannot be used by the human brain. The brain is a massive glucose hog that requires a steady supply of glucose as fuel, I've read citations indicating upwards of 100g of CHO per day just for brain function.

The flux of aminos caused by the rapid absorption of whey creates a large excess of aminos your body readily converts into glucose. The fasted state is important because your brain/body is starving for glucose and makes the study relevant to what has been observed in keto dieters relying on whey as a primary protein source. The keto diet used medically is a high fat, low carb and low protein diet. The low protein content limits the chance of excess aminos being converted into glucose; The typical ratio is 3g fat for every gram of combined carbs and protein. Personally, I'm not a fan of keto diets for bodybuilders and think a diet of more moderate CHO consumption is more appropriate, approximately 1g CHO per pound. But hey, if it works for then keep doing it!

See this is why you should not listen to certain people. These peope do NOT know what they are talking about . The first sentance tells me that javaguru needs more study and need to listen to dieticians.

If fats are not turned into glucose then how does one lose stored body fat in the first place???

Please , all the bad advice needs to end

LMAO, you need to work on your reading comprehension! Those links are about proteins/glucose being turned into fat. The first is also blatantly wrong on several points; I didn't intend this to become a biochem lesson but only three things can be used for neoglucogenesis(creating glucose from non CHO sources); Those are lactate, glycerol and amino acids. Most fatty acids cannot be turned into glucose unless the glyoxylate cycle is used, the exception being odd-chain fatty acids which can yield propionyl CoA, a precursor for oxaloacetate.

FYI, Fatty acids are transported to the cellular mitiochondria to be burned. Here is a link to a simple explanation of the process used to burn fat.

No , you need to work on your readin comprehension...

excerpt from http://www.answerbag.com/q_view.php/16001

But ALL glucose IS carbohydrate. And your liver does convert stored fat into glucose. Your body has very little use for fat. Cholesterol is a fatty alcohol and hormones are made from fat. However, there is very little else your body does with fat besides store it. Everything else uses carbohydrates and proteins and it's your liver that converts stored fat to carbohydrates.

Also excerpt from http://home.howstuffworks.com/fat-cell3.htm

Insulin
When you eat a candy bar or a meal, the presence of glucose, amino acids or fatty acids in the intestine stimulates the pancreas to secrete a hormone called insulin. Insulin acts on many cells in your body, especially those in the liver, muscle and fat tissue. Insulin tells the cells to do the following:

* Absorb glucose, fatty acids and amino acids
* Stop breaking down:
o glucose, fatty acids and amino acids
o glycogen into glucose
o fats into fatty acids and glycerol
o proteins into amino acids
* Start building:
o glycogen from glucose
o fats (triglycerides) from glycerol and fatty acids
o proteins from amino acids

Yes fats , although inefficient, do get converted to glucose

And please read your own link

High protein, low fat, low carbohydrate diets.

High protein, low fat, low carbohydrate diets offer a mechanism for fat reduction. The amino acids in the diet provide the oxaloacetate required for gluconeogenesis. Body fat and the amino acids provide ATP.

An example of such a diet would be a diet based around fish meat. The suitability of such a diet for fat reduction is probably not a straight forward matter as other complications may arise.

I am skipping the conclusion just after this because atkins works

Also let's define the term gluconeogenesis
http://www.elmhurst.edu/~chm/vchembook/604glycogenesis.html

Gluconeogenesis is the process of synthesizing glucose from non-carbohydrate sources. The starting point of gluconeogenesis is pyruvic acid, although oxaloacetic acid and dihydroxyacetone phosphate also provide entry points. Lactic acid, some amino acids from protein and glycerol from fat can be converted into glucose. Gluconeogenesis is similar but not the exact reverse of glycolysis, some of the steps are the identical in reverse direction and three of them are new ones. Without going into detail, the general gluconeogenesis sequence is given in the graphic on the left.

If you're going to post a reference link, please use a credible scientific/academic source, Answerbag hardly qualifies.

Glycerol, as I stated, can be converted via gluconeogenesis but it's not a fatty acid.
Most fatty acids cannot be turned into glucose unless the glyoxylate cycle is used, the exception being odd-chain fatty acids which can yield propionyl CoA, a precursor for oxaloacetate. Stored fat is released as fatty acids and glycerol. The fatty acids convert to AcetylCoA which then converts to citric acid and begins the TCA cycle for creation of ATP; It does not convert to glucose at any point in this cycle.

The last link you posted just confirms what I have already posted and you seem to be trying to argue things that are irrelevant or undisputed? The insulin post is simply superfluous. You're just proving my point by referencing my link with the High Protein, Low Carb, Low fat diet. See where the fatty acids enter the equation? Finally, if your body actually converted signifigant amounts of glucose from fats the human brain wouldn't need to use ketones, it would simply use it's preferred energy source (glucose), and that is simply not the case!

The analysis of someone who doesn't know what they are talking about is what hardly qualifies as a credible source...

1. noone said that glycerol is a fatty acid except you...
2. You are oversimplifying the mechanisms of the liver with some "college" education on metabolic processes.
3. You need to post information about the human brain using ketones. I never entered this arena. My point was that fats can be converted into glucose OR ketones

What are ketones?

Ketones are a normal and efficient source of fuel and energy for the human body. They are produced by the liver from fatty acids, which result from the breakdown of body fat in response to the absence of glucose/sugar. In a ketogenic diet, such as Atkins ... or diets used for treating epilepsy in children, the tiny amounts of glucose required for some select functions can be met by consuming a minimum amount of carbs - or can be manufactured in the liver from PROTEIN. When your body is producing ketones, and using them for fuel, this is called "ketosis".

Jesus , what in the blue hell was I typing???

I think you are correct about certain things , but this got too argumentative
Anyway no sob stores from me just accept my apologies
