I've been on a similar quest to yourself (although my background is in law). I could not accept the health messages we were being fed (pardon the pun) without examining the evidence. At the end of a 4 year quest I became convinced that evidence overwhelmingly supported a conclusion that fructose (and the strange loopholes in our metabolism relating to it) was directly responsible for much that troubles the modern health systems of western countries.<BR/><BR/>I was lucky enough to have Penguin agree that it was a story worth telling in print form and the book hit the streets this week. You can read more about it at www.sweetpoison.com.au Try to ignore the populist spin, it really does get down to brass tacks as you get into it. I would love any feedback you would care to give and I intend to stay tuned to your posts from now on.<BR/><BR/>Cheers<BR/>David.David Gillespiehttps://www.blogger.com/profile/07052209917330423121noreply@blogger.comtag:blogger.com,1999:blog-7721098568390636553.post-71889448983522028742008-08-08T23:07:00.000-07:002008-08-08T23:07:00.000-07:00First, a quick correction: I slipped a decimal poi...First, a quick correction: I slipped a decimal point and calculated for a 10 g serving rather than a 100 g serving! My apologies. The ice cream serving will provide 58.2 kcal of cooling—more, but still not a lot, and most of it comes from the phase transition.<BR/><BR/>As to how energy can be excreted, it seems to me that there must be upper limits on how much food can be processed and how much energy can be stored in the period that processed food is resident in the digestive tract. Therefore, if you binge-eat or feast to consume more than this limit, then the excess should just pass all the way through the intestines and exit in the feces. It's just not clear how much gets excreted this way.<BR/><BR/>Without having done much research into this, we know that Ca intake can result in lipids being bound in the intestines and ultimately excreted without ever being absorbed. Same for soluble fiber—it interferes with formation of bile salt micelles and the resorption of these lipids (as well as some fat soluble vitamins probably), and is supposed to be the mechanism by which fiber lowers serum cholesterol (since bile salts are a form of cholesterol). <BR/><BR/>The postprandial thermogenesis shows a measureable dietary effect, but it's only about 0.2° F, and that's not going to result in a lot of additional energy loss even if the temperature remains elevated for a couple of hours. In fact the authors also show a post-prandial increase in resting energy expenditure of about 8 kcal/hr, which would clearly be lost in the noise of food quantities consumed. The authors claim a cumulative excess loss of about 90 kcal/day, roughly equivalent to about one extra "serving" of something, and still not enough to explain the observed difference in weight loss in my opinion. In this paper, both diets were 59% carbohydrates—I suspect that much more dramatic weight loss would be observed on a low carb diet!<BR/><BR/>This is not to say that we don't believe there could be dietary effects on energy balance, but it's not clear that people are looking at all the relevant factors yet.Drs.

You look at the nutritional label on your ice cream and find that it has, say, 250 Cal per 100 g serving. Then you say, well, I know that ice cream has a specific heat of about 1 cal/g-C plus I have to unfreeze it at about 540 cal/g. So to raise the ice cream from solid at -5 C to liquid in the body at +37 C requires about 582 cal/g or 5820 cal for our 100 g serving. Wow! a net loss of 5820 - 250 = 5570 cal. Let's all eat ice cream and lose weight!<BR/><BR/>The problem, of course, is that the big-C Calorie used in nutrition is actually a kilocalorie (1000 small-c calories), so the arithmetic wasn't quite right...<BR/><BR/>The point is that while heat transfer obviously contributes to overall energy balance, it is usually a small effect. The body has important mechanisms for preserving and shedding heat, but they're there mostly to keep your body temperature under control, and I doubt that they play a very significant role in overall energy balance. My suspicion is that the key mechanism for dealing with excess food energy beyond that that can reasonably be stored in the short term is very simple: you just excrete it. I don't know why most accounts leave out this important method of disposing of excess energy.<BR/><BR/>(See also <A HREF="http://ramblingoutsidethebox.blogspot.com/2008/07/more-on.html" REL="nofollow">our blog</A> on the same topic.)Drs.

No lame questions here.<BR/><BR/>Impairment of the regulatory system is what I believe causes obesity (and probably a lot of other problems as well). There are so many checks and balances in place that I find it very hard to believe that in healthy people consumption of minor caloric excesses leads to obesity. Going back to the water example, it's like saying that drinking an extra teaspoon of water every day ultimately leads to water poisoning. Any organism whose survival was that sensitive to a common environmental influence probably wouldn't last very long.<BR/><BR/>Hormones are a key part of the regulatory system. If the hormone levels are out of wack, or if the signals are not being received from the hormones, then the system is broken. Hormones also activate genes, so genetic issues can also arise, where the hormonal signal does not cause the desired effect.<BR/><BR/>I don't the answer to your question about hypertension. Some hypertension can be caused by blood vessels being constricted. This can be caused by chronic stress: one of the effects of stress hormones is to constrict blood vessels and increase blood pressure. That's a good thing if you're being chased by a lion, not so much if you get cut off in traffic. Does anybody else know if/how hypertension could be caused by impairment of water regulation?Davehttps://www.blogger.com/profile/18290594860469294453noreply@blogger.comtag:blogger.com,1999:blog-7721098568390636553.post-22869283121495619502008-07-22T22:29:00.000-07:002008-07-22T22:29:00.000-07:00Hi Mel.

About the only thing I can think of is the ambient temperature, in the sense that when it's warm, the body doesn't need to generate as much of it's own heat. I can't think of any way other than eating that we would get some source of energy that directly leads to energy molecules like ATP.

But that implies a pronounced lack of robustness in the regulatory system, one which is not observed, any more than it is in regulating water balance."<BR/><BR/>But can the regulatory system be impaired in some way where it plays a part in fat accumulation? Or is it the hormones influencing the regulatory system? In hypertension is the regulatory system not regulating water balance properly?<BR/><BR/>Sorry if questions are lame as I admit some of your post I didn't understand.Suehttps://www.blogger.com/profile/03181442844616803097noreply@blogger.com
