Basically it says that your body can produce enough glocose from the protein in your diet so that it prevents you from going into even moderate ketosis.

After all the talk about the Ketogenic diet I decided to give it another go. What I found was pretty interesting. After 4 days on the diet I eventually went into slight ketosis. Two hours after that test I had a whey protein shake made with water and I also had a couple of table spoons of Olive oil. Two hours after that, using Keto sticks I tested myself and found I was completely out of ketosis.

I had been told before, that Whey rapidly converts to glucose in your liver and now this had proven it too me.

So I did a search for anything related to whey and it's conversion to glucose. I stumbled across this web page.

"high quality proteins such as whey have been demonstrated to be quickly oxidized for energy or converted into glocose by the body"

Basically the guy says that Whey is an expensive glucose source.

This would suggest that Whey would not be the ideal protein source for dieting, due to the ease with which it converts to glucose.

Therefore slow release proteins such as whole food sources and Casein would be a much better alternative for dieters.

But to say the diet doesn't work is not true. You just HAVE to limit your protein intake and eat plenty of fats. It is also not necessary (as ducchaine pointed out) to be in 'ketosis' for your body to make a shift to burning more fats for fuel and make the diet work.

she sounds wrong,plus she is very anti-protein and anti-atkins,she is not a vegetarian shes just very anti -protein,anyway i was telilng her about atkins and how it works,becaues i was pissed that she kept telling the class when u go on atkins u will lose all your muscles,but after trying to explain to her more than once,i just quit she really stuck it in about glucogenius in this weeks class,we were going over the test and side tracted for 10 min and said kept saying this is whats gonna happen if u go atkins diet,anyway i wasnt gonna raise my hand because i already had told her on more than one occasion that your body does not relly on muscle tissue for fuel while on atkins,but i think the more i say it the more she wants to stick it in peoples head that it does,so i didnt want to start controversy so i just kept it to myself, she also refers to it as once u go to sleep at night and starve ,what happens u go into glucognesis ( in her defeintion eats muscle) but theirs no way glycogen will run out one nights sleep, so again i kept comments to myself,one thing that i am not sure she also said egg protein has the highest biological value,and i wasnt sure of if whey did or not,becaues i wasnt sure i asked,what about whey protein where does it rank because its the most popular protein,she said its good but lower than egg and she knows shes seen in the muscle and fitness magiezine,is this true? also as i was saying it i said whey ,and she said something like oh thats from milk right,i said i heard its derived from cheese,she said its the same thing its from milk,but i swear it comes from cheese?
she also says too much protein is damgeing to your liver and kidneys,i rose my hand here becaues this would be my the first time i confronted her on this subject,anyway i said i have heard that in healty people your body can handle as much protein u put in it,then she changed her answer and said,well it puts unnecceasry stess,then i said but its not gonna hurt it will u,then she switched and said well for diabetics it is harmful and alot of us people are diabetics,then she also said about it lowering calcium retention,i didnt say anything because i am not sure of this,i think that real studies not epidermalogic do not show it to lose calicum but im not sure,can someone clear all this up for me

i feel like this class is starting to poison me,whenever she talks about atkins diet eating your muscles or other negative/false stuff ,some of the time she goes on it for 10 min on a certain topic like glucagensis,and its hard to shut it out of your mind, i want to ask her to show me studies ,but i feel like that would cause static and come across like im fightingm,dont get decieved by my tone,shes not a mean persons,shes a cool teacher,she knows alot,but she just has alot of anti-protein ,anti-atkins diet views,and she tends to keep talking about and making up /stretching things about protein intake,i just dont want to get the wrongs belives and then come out of this class at the end of the semester knowing less than i did at the start u know,

Several things to keep in mind when your teacher raises these points. The first one is the concept held by many nutritionists and much of the medical community that "ketosis" means "starvation". There are many studies that show both in diabetic ketoacidosis and a similar state that sets in after 3-7 days of starvation (in other words NO food intake) that the proteins in muscle provide some (but not all) of the precursors for gluconeogenesis to keep the brain alive. At this level of starvation the body will catabolize around 30 grams of muscle per day. But this is NOT necessarily true when there is a significant source of dietary amino acids. Your nutrition teacher also does not sound (from your description) to distinguish between 'ketogenic' diets and 'cyclical ketogenic' diets. In the first case (such as Atkins) protein tissue will probably be lost if the person is also undergoing heavy weight training (anaerobic). But they should otherwise burn mainly fat. In the second case (CKD) the timing of heavy weight training relative to carb intake is timed so that the muscles can take full advantage of muscle glycogen stores instead of relying on gluconeogenesis. This is why it is not advised to hit the weights heavy once you're in ketosis on a CKD. In other words CKD (unlike Atkin's) is designed specifically to help retain muscle while losing fat in ketosis.

As a side note, you may wish to point out to her that gluconeogenesis does not=burning muscle. In a ketogenic state if you have enough fat lying around over half of gluconeogenesis will come from the glycerol residues that result from oxidation of fatty acids.

As far as biological value, suffice it to say that this is a very controversial topic and is really only relevant if your protein intake is marginal to deficient. In your well fed American population it is nearly meaningless.

Ummmm what else? Whey is the fluid left over after you've curdled milk. It is a leftover by-product from cheese manufacture.

High protein diets can stress the liver and kidneys if you've got a pre-existing condition or don't drink enough water. How many of you have had older cats suffer from kidney failure??? Lots I'll bet. A high salt diet, lots of alcohol,many oral steroids or too much Tylenol can also cause this! So what? As long as you know there is a risk and how to avoid problems then there is no big prob with short term high protein diets.

i had brought up atkins diet quite a few times but i was not gonna raise my hand and confront her what she said anymore,because i didnt want to come off as a fight,but the first time (2nd week of class) ,that day she was saying on atkins diet your body totally runs out of glycogen and then your body starts feeding off your muscles and u have no energy etc,i told her that is why alot of people do a weekend carb up do replenish glyocgen for the week, but she belives that is not enough

the reason this atkins diet was brought up was in the first day of class someone asked about it,then people were asking about the zone diet too,then after that she kept using reference to the atkins diet or a high protein diet when talking about something else

This time I was just trying a high fat/protein low carb diet to lower my bodyfat for a modelling session, but seen the results, I'm thinking on going on load/unload Anabolic Diet's cycle, do you know a good book to read about? I want to grow, but this must be subordinated to definition.

Like an issue I was reading a couple of years ago where they had an article about squatting entitled "Rep to 100 and GROW!!"
