Burn more calories & bodyfat, get fitter, get slimmer & lose more visceral fat with Vitamin D.

Well, that got your attention! I just spent ages trawling through PubMed searching for Vitamin D studies from 2010 to present. I found 35 worth linking to. Here are the three relevant to the title:-

Diet induced thermogenesis, fat oxidation and food intake following sequential meals: influence of calcium and vitamin D.

Relation of vitamin D level to maximal oxygen uptake in adults.

Calcium and vitamin D supplementation is associated with decreased abdominal visceral adipose tissue in overweight and obese adults.

Vitamin D3 and the risk of CVD in overweight and obese women: a randomised controlled trial.

EDIT: I just had a thought. I find Vitamin D3 5,000iu/day very mentally stimulating.
I wonder if it's affecting
CART. That would explain its anorectic effect.

What are your thoughts on natural vit D vs supplements. Nevermind, I forgot you lived in England.

No, seriously, how do you consider vit D in a pill to vit D via the Sun? Is there relevant data for this? Of course for older people like you mother it is more difficult to synthesize vit D via the skin, especially if they don't get enough cholesterol in the diet.

Hi Sean. Sorry it took so long to moderate your post, but I can't log-in to Blogger from my Blackberry. There's a script problem or something. I was visiting mum.

Anyway, Vitamin D3 in a gel-cap is bio-identical to the Vitamin D3 that's synthesised in our skins. It's extracted from the lanolin on the wool sheared off sheep. They do the sunbathing, so we don't have to. Vitamin D3 5,000iu/day in gel-caps raised my serum 25(OH)D just fine.

I don't know why old people's skins are less efficient at synthesising Vitamin D3 than young people's. I don't think that cholesterol is the limiting factor.

I would guess that it is related to losing the "glossiness" in the skin as we age. Young people's skin is probably more translucent. Old people are often referred to as having papery skin, so a lot of the UV is being reflected in a diffuse manner.

Of course, as we age we get less efficient at doing everything except blogging.

Just before I go to visit mum...

There's that test where you pinch the skin on the back of your hand extremely hard, let go and see how long it takes to go flat. Mine takes about 4 seconds.

Supposedly, it means that I have the skin of a 40 year old. He's going to want it back!

I seem to have the brain of an 18 year old....

Nah, you've got the brain of a 30-year old - that of one of Allah's prophets.

Here is a quote I found in a Finance message thread.

"Andrew Lo, of MIT’s Sloan School of Management, was fond of pointing out that in the physical sciences three laws can explain 99% of behaviour, whereas in finance 99 laws can explain at best 3% of behaviour".

Substitute Dietetic for Finance and you have my view of so much that is blogged about.

Nothing to do with Vit D - thought it would be echoed by N N Taleb.

Hi, Nigel

I have a simple question. Do you acknowledge that Dr. Jeffrey Friedman is far more knowledgeable about obesity than either Lyle McDonald, CarbSane or Anthony Colpo?

Why would you not choose Dr. Friedman ( one of the most pioneering scientists in the world on this topic) over them for your obesity information? I cannot understand that?

The gurus information is not congruent with Dr. Friedman's.Dr. Friedman's information is the same as Dr. Douglas Coleman,and other top obesity scientists.

Dr. Stephan Guyenet is also far more knowledgeable than Lyle McDonald. Steohan would acknowledge Dr. Fridman is a top expert in the field.

Have you read "Modern Science Versus The Stigma Of Obesity?" a scientific publication by Dr Fridan. If so how could you possibly support the Internet salesman McDonald?

"Hi, Nigel

I have a simple answer. No! You're comparing apples with oranges, grapes & bananas.
McDonald is an expert at what he does (see his books).
CarbSane doesn't offer dietary advice. She debunks bullshit on the internet, as do I but not as well.
Colpo has a similar target audience to McDonald, but in a different country.
What does Friedman do, exactly? Is he a researcher, like Guyenet?

"Why would you not choose Dr. Friedman ( one of the most pioneering scientists in the world on this topic) over them for your obesity information? I cannot understand that?"
See above.

"The gurus information is not congruent with Dr. Friedman's.Dr. Friedman's information is the same as Dr. Douglas Coleman,and other top obesity scientists."
I prefer to not use terms like "guru".

"Dr. Stephan Guyenet is also far more knowledgeable than Lyle McDonald. Steohan would acknowledge Dr. Fridman is a top expert in the field."
Guyenet is an obesity researcher, so he does something different from McDonald et al.

"Have you read "Modern Science Versus The Stigma Of Obesity?" a scientific publication by Dr Fridan. If so how could you possibly support the Internet salesman McDonald?"
What, THIS? Friedman is defeatist e.g. "This simplistic notion is at odds with substantial scientific evidence illuminating a precise and powerful biologic system that maintains body weight within a relatively narrow range."
I completely and utterly disagree with him! This is why I don't follow him. McDonald & Colpo actually get results.
