Buy her Taubes book.....it chronicles over 125 yrs of solid data. If she does not get it after that forget it......

When people ask for the science...I send them that link, mind you thats after multiple conversations and explanations. Not sure it will help, but maybe if you compile the articles instead of giving her a blog, she might be more open minded?

Ketosis that the bariatric nurse was speaking of is when your lack of insulin causes a person's body to begin to eat its own muscle and fat. Rapid weight loss occurs along with high blood sugar. You will begin Eating as much as you can because you feel you are starving, but this does not remedy the hunger. After a few months of this, if you are very over weight, You will have lost about 80 pounds and you will find it hard to breathe. Upon entering the ER be told that you are minutes away from a massive heart attack. My best friend was there and I met her at the ER. The doctor grabbed me and told me that my friend was in very serious condition. They put her in intensive care. She is now type 1 diabetic. She had no insulin in her body to use what she was eating as fuel. She was peeing pure sugar and her body was cannibalizing itself to stay alive.

I use keto sticks to help me STAY in ketosis on a very controlled carb diet. This is entirely different from what that bariatric nurse was speaking of. This type of ketosis is not harmful. It is the state where I am not allowing my body to release insulin because I am over weight and I want to switch from storing fat to burning fat. My insulin resistance is such that I STORE every carb I eat as fat. My high insulin levels will not allow me to burn carbs as energy. I need to eat under 20 carbs a day to lose weight. I am hoping that some day I can add back some carbs like fruit and not gain weight back.I will do so when I am at the weight I need to be at. I will then experiment with how much I can add back if any. My father had a massive stoke at age 65. He has been on this type of diet for 18 years. His blood work is now perfect. My doctor says that in spite of the fact that half his body is not very mobile, my father is his healthiest patient. The addition of coconut oil has begun, even after 18 years, to help him speak again. He is not on any medication.

In response to Jay and this not being a religion: speaking in my case and for me, here is why I have counter-consensus views about carbs: I am obese, and have tried many, many diets, and have hurt my heart by exercise, and have had roux-en-y gastric bypass - in other words: even though I have no biochem or med credentials, I nevertheless am responsible for the body I am in, and must do my best to provide proper stewardship for it even though I don't happen to have a PhD in anything. And perhaps Butters is in a similar position: s/he has tried what the CW pontificates, and it didn't work, and at that point Butters began questioning the CW and its basis - EVEN THOUGH BUTTERS MAY NOT (AND I DO NOT) HAVE THE NECESSARY TECHNICAL BACKGROUND TO UNDERSTAND STUDIES THAT PRESUPPOSE CALCULUS AND INORGANIC CHEMISTRY AND BIOCHEMISTRY AND PHARMACOLOGY AND STATISTICS AND PHYSICS AND...ETC. I hope this explanation has clarified for you how people can have counter-consensus views while at the same time they have not seen (or understood) studies themselves. I find that one of the problems with CarbSane's comments, to further illustrate my point, is that she quotes highly technical studies in her posts but offers no "translation" in most of them, so laypeople come away from reading her stuff without a clear and jargon-free summation; and as a result the impression she leaves is of someone with an emotional ax to grind but with little ability to communicate to the great scientific unwashed. It doesn't make me doubt her scientific expertise, but it does make me want to avoid reading her posts. Not everyone in the world with an opinion about diet must base that opinion on highly technical peer-reviewed studies. Right?

NHS and FSA are completely CW. So no help there. Met an (overweight) NHS bariatric nurse last year.

She said going into ketosis (as indicated by ketostiks) was an illness to be avoided at all costs!

I'm not sure what nutrition profile you go for, but I know that Harvard suggests that 20% of diet to 42% of diet being from fat is acceptable (although this is at 25%mono, 10% poly, 7%sat). That is relatively high fat.

But for the most part CW likes low carb and paleo type for treating (reversing) diabetes in a way that whole grains do not accomplish. Here is a review of the last Taubes book at the Science-Based Medicine site: http://www.sciencebasedmedicine.org/?p=9841#comments

It is fairly critical of low carb, but then there are other doctors arguing about it in the comments. So low carb is somewhat supported, but its just not going to be officially backed by the AHA. One study that turned out fairly pro-low-carb (and was done to prove low carb was bad oddly enough) was the Stanford AtoZ diet experiment (good presentation on Youtube). In it they broke out the advantages of low carb on all health markers, and on how at least half of overweight people benefit more from being low carb due to insulin issues.

This isn't a religion. If you haven't seen studies yourself or very convincing discussion of them, why do you have any counter-consensus views about carbs?

nutrition and metabolism society has lots of published research studies that support our ideas.

Surprised no one has mentioned the new paleo paper.
It's linked in this post: http://wholehealthsource.blogspot.com/2011/03/new-ancestral-diet-review-paper.html

Fairly heavy-duty. but very legitimate & scientific (peer reviewed) paper on "The western diet and lifestyle and diseases of civilization" http://www.dovepress.com/the-western-diet-and-lifestyle-and-diseases-of-civilization-peer-reviewed-article-RRCC

I've not read the whole paper yet, but it was mentioned on today's Latest In Paleo podcast and seems to concur with many Paleo beliefs.
