The Cause of Obesity

Professor Robert H. Lustig, MD, is an expert on obesity and an internet rock star. Just one of his many lectures has over TWO MILLION views on YouTube.

Here professor Lustig describes why we get fat and what to do about it. It's not what most people think.

This guy is fat - why would I listen to anything he had to say if I wanted to loose weight ?

[perfectdiversion]

insulin this insulin that... blah blah. its simple insulin is the hormone to lower blood sugar... people are never educated on other factors that raise blood sugar (glucagon, cortisol) all the time because of peoples diets where blood sugar isnt regulated throughout the day through ratios of macro nutrients that work for them

[BroccoliBeefed]

None of these high-falutin western medicine doctors never address the fact that the USA's food supply is poisoned. The main problem is processed foods and lack of exercise. Butter is not naturally white, neither is flour or cane sugar. Cows should not be eating each other or corn or junk food. Many of them are not fed live grass or grass at all, so they are not getting all the Omega 3 acids they used to get. What a hot mess. It's sad.

I see you didn't make it past the abstract; several clinical studies have demonstrated that increased blood lipid content reduces the efficacy of a given amount of insulin to remove glucose from the bloodstream. And nobody in the nutrition world propagates bad science worse than Lustig and Taubes; well, except maybe T. Colin Campbell.

I definitely didn't "listen;" I read it. And I looked through that Giacco study. Know how he came to that conclusion? The same way those idiots in America did back in the 1950s (Ancel Keys & company)...by taking observational/epidemiological data and throwing scientific causal analysis to the wind. He did exactly what I predicted he did, which is simply look at populus-wide fat intake levels on a chart and say it caused the diseases it corresponded to. You've got to watch out for bad science.

[Beavis1260]

Ohh, now I realize why this back-and-forth. I said "unrefined" in my original comment way down there, and I meant "refined." Oops, brain fart. I'm sure you'll agree there is plenty of evidence and logic beyond a reasonable doubt that refined carbs help promote hyperinsulinemia.

[MacGamut15]

Did I ever deny that insulin makes people gain weight? No, I did not. I said in my first comment "High insulin does promote weight gain." That study shows that insulin is not, however, the only hormone which regulates body weight.

You're a waste of time, Beavis. How many times have I pressured you for evidence that unrefined carbs promote hyperinsulinemia and you couldn't provide it?

[Eli S]

You didn't listen to what I said; elevated blood lipid content (especially from saturated fat intake) reduces the efficacy of a given amount of insulin to remove glucose from the blood stream. Any macronutrient that isn't metabolized, is stored as fat. There are many, many studies that demonstrate this. Riccardi G, Giacco R, Rivellese AA. "Dietary fat, insulin sensitivity and the metabolic syndrome". Clin Nutr. 2004 Aug;23(4):447-56.

Ok, I have read it now. My question is, have you? That study does not contradict my points; if anything, it reinforces them. It's perfectly logical that if the blood is full of fatty acids, the fat tissue would not release its own FFAs, because your cells are already being fed by what you've just eaten. Furthermore, it said insulin "is important for reesterification of fatty acids in adipose tissue," i.e. putting it back into storage. Now it is my turn to LOL.
