If there were time...

Well, being back online is one thing. Having the time to actually do any posting appears to be quite another... At the moment I'm actually sleeping until 6am, well after the time I'm usually writing posts. Life is exceedingly busy with life type things, especially the house, garden, work and emergency patching up of our elderly Miata. As life settles down I'll get back to posting again but for the next few weeks it's just not a practical proposition!

Thanks to all for the comments about the family on the last post and for links emailed.

Just wondering if you have any opinions regarding the CKD diet?

'Cyclic Ketogenic Diet'

Is there anything to the idea that if you are working out that there should be a period of carb loading? Recommendations are for a specific amount of carbs to be eaten over a 24-30 hour period at the end of the week.

Peter we missed you today at AHS but we were all thinking of you. Get settled and come out with a vengence......we need you voice and value your brain.

"If there was time..."

should be "If there were time..."

Actually, either could apply, simply because English evolves and new usages happen spontaneously all the time.

@Pierre,
a cyclic ketogenic diet seems extremely silly and quite unhealthy. The body has no ability to adapt to such rapid changes. These diets are popular with bodybuilders,

Body builders are generally narcissistic morons with latent homosexual tendencies. Totally ignore anything they say or do.

Pierre said...

hehe...thanks for the response blogblog. My bodybuilding days never were and never will be considering the shape my shoulders are in, rotator cuff issues. But after losing 30 pounds it has been a lot of fun to push hard to get in shape. Thank you for the response.

Peter,

Really curious on your take about Stephan's current post - http://wholehealthsource.blogspot.com/2011/08/carbohydrate-hypothesis-of-obesity.html

As Aravind posted:

I too am curious about your thoughts on Stephen and Paul's recent posts. (I think Paul's is more reasonable...)

Based on my personal experiences, I am more in line with yours and Stan's thoughts on things.

Aravind said...

In Peter's potato post, he wrote the following - "Ultimately the ability to live on varied macronutrient ratios comes down to how broken you are, especially your liver".

I have never intrepreted Peter as being "anti carb" as such. But as he also wrote "none of us are Kitavans" and that avoiding carbs side steps a host of problems once metabolically deranged and/or years of SAD.

Anyway, Peter's input is eagerly awaited :-)

Aravind said...

So I guess the pivotal point - cause of metabolic derangement vs remediation once deranged. The former is the issue at hand, not so much the latter.

@Aravind,

Really curious on your take about Stephan's current post - http://wholehealthsource.blogspot.com/2011/08/carbohydrate-hypothesis-of-obesity.html

Unfortunately Stephan is afflicted with both youthful arrogance and ignorance. He has a very limited understanding of the lifestyle context of the societies mentioned or the role of physical activity in obesity.

The fact is that you will always stay thin or lose weight on a very high carbohydrate diet if you do enough hard physical activity. That is why most Tour de France riders lose weight despite 6000Cal/day diets comprised mostly of refined carbohydrates.

Societies typically start to become obese around 20 years after physical labout is greatly reduced and cars and motorcycles become common. Sugar was cheap and abundant by the 1840s yet obesity didn't become common in Western countries until the mid-late 20th century. The public health textbook Food and Nutrition in Australia showed that total sugar consumption in Australia was at least as high in the early 20th century as the 1980s. Caloric intake in Australia was much higher 100 years ago than now.

SG Argument: the Taiwanese, Chinese and Japanese were thin on a white rice diet.

Fact: Most people in these societies lived in state of perpetual near-starvation combined with constant hard physical labour. They were thin not healthy.

SG Arguument: Kitiva Studies.

Fact: More like third rate epidemiology.
- no birth or death records.
- no post mortems or death certificates.
- very superficial medical examinations [resting ECG]
- it is well understood in academic anthropology that people in "primitive" societies are notorious for making blatantly false claims about their superiority. These claims typically include extreme longevity, outstanding health, incredible sexual stamina etc. It is also true that observation always subtly changes behaviour is tesr subjects.

There is also the claim that Kitivan spend about the same amount of time in physical activity as Swedes. However it is intensity - not time - that counts. eg A person walking barefoot on soft soil at 8km/h (Kitivan) uses 4-6x as much energy per hour as person walking at 4km/h on a footpath (Swede). In fact it is quite possble to exercise a world class athlete to failure in as little as 10-20 seconds.

Aravind and Melodie,

Stephan wrote:

"I'd like to begin by emphasizing that carbohydrate restriction has helped many people lose body fat and improve their metabolic health."

and

"However, once overweight or obesity is established, carbohydrate restriction can aid fat loss in some people."

Broken people require carbohydrate restriction to live with their broken-ness. They probably need it years before obesity is established.

As came through on the more sensible comments on Stephan's posts, there is a difference between a broken and an unbroken human being. My grandmother was a type two diabetic. My X chromosome and many of my mitochondria may well have come from her. I personally appear to benefit from carbohydrate restriction.

What you can eat as a 20 year old athlete and what you can eat as a 55 year old clinician may not be the same if your grandmother was a type 2 diabetic.

Perhaps the reward hypothesis explains the small spontaneous weight loss observed in the study headed by Barnard using broken people labeled as having type 2 diabetes. Using a reduced reward carbohydrate based diet to lower body fat set point is clearly utterly useless for improving health in these people, as judged by HbA1c.

I would like to follow Stephan's references to see if they can convince me that hyperinsulinaemia is irrelevant to weight gain/loss. I'm not holding my breath. I quite like this quote:

"The growth of knowledge depends entirely on disagreement"


Ultimately I need to do some reading, a luxury I am currently deprived of.

There is a rumour of a locum to support the current skeleton veterinary staff at work and even of the unwell vet returning gradually to work. I may get time to read. Currently my life consists of performing a mean ovariohysterectomy or two on a busy theatre list and consulting until rather late in the evenings...

Peter,

Looking forward to your astute analysis and comments on the debate between Stephan and Taubes. The comments from the sweet potato cult on Stephan's blog forgot to mention those of us who are metabolically broken and don't process carbs well. Thanks for addressing the age issue as it is related to metabolism.

@STG
there have been many claims of (near) vegetarian societies which have supposedly extraordinary health and longevity eg Okinawa, Hunza and Crete.

Without exception these claims have proven false when extensively investigated.
