Mythology of Obesity, or of Gary Taubes? » Weightology


by James Kreiger - Weightlogy

Jun 232010

Extract:

In my last post on Gary Taubes and his book Good Calories, Bad Calories, I stated that I would do a chapter-by-chapter critique of the book, starting with Chapter 14, “The Mythology of Obesity”. In this chapter, Taubes begins to create a mystery that doesn’t actually exist. He does this through a combination of logical fallacies, selective quotation of out-dated scientific data, and leaving out existing data that conflicts with his statements.
Taubes opens the chapter with this sentence:
“Critical to the success of any scientific enterprise is the ability to make accurate and unbiased observations.”
He then goes on to say:
“…if the initial observations are incorrect or incomplete, then we will distort what it is we’re trying to explain.”
Taubes is correct in these statements. Unfortunately he doesn’t follow his own advice. [etc]

"Insulin spikes = fat gain" - more doubts expressed

My Carb Sane-Asylum: See? I Told You So!!

by Carbsane:

I've got to say, I about fell off my chair reading the following comment from Stephan Guyenet over at Whole Health Source blog as it flittered through my feed reader. In response to a comment by Thomas, basically asking if insulin surges or calories ultimately govern weight loss/gain, Stephan had this to say:
Yes, the excess calorie consumption is the key. Insulin spikes do not increase food intake unless they cause hypoglycemia. In fact, insulin is kind of like leptin's kid brother: it acts in the brain to constrain fat mass.
Also, insulin is co-secreted with amylin, which also constrains fat mass by increasing satiation and possibly leptin sensitivity.

All this postprandial insulin spikes = fat gain stuff is nonsense as far as I can tell. I still haven't seen a shred of convincing evidence to support it, and in fact, the evidence I've seen mostly supports the opposite hypothesis, that insulin spikes oppose fat gain. The idea that postprandial insulin causes fat gain is contradicted by the most basic empirical facts in both human and animal studies. As I said before, I don't know a single person who studies metabolism/endocrinology professionally who takes that idea seriously-- it is confined to the popular press and internet blogs/forums.
Been saying this and backing it up with citations galore for over a year now. I'm excited to see others finally setting the record straight publicly. First Stephan comes out as a not-so-closet potato eater. Now he's forthrightly rejected Taubes' insulin hypothesis. What next? Dancing with the Stars? Or perhaps the next institution of higher learning inclined to invite Gary Taubes to lecture their medical students might be better served inviting someone else.

Low carb - Gary Taubes on the evils of carbohydrates

nb: Scientists now saying carbs, not fat, are to blame for America's ills - latimes.com

below a short abc (US) feature introducing low carb proponent Gary Taubes (http://en.wikipedia.org/wiki/Gary_Taubes):



in 2002 Taubes first challenged traditional wisdom on the basis for obesity (ie: http://www.nytimes.com/2010/12/28/health/28zuger.html ) and provoked a lot of debate on accepted dogmas in the process.he advocates a high saturated fat dietary intake.

most recently he has written about the sugar-cancer connection (http://www.nytimes.com/2011/04/17/magazine/mag-17Sugar-t.html ), with parallels to the the Robert Lustig's disease/sugar thesis

some "Top Comments" from You Tube ( see all ):
  • Gary Taubes is what Galileo was to Copernicus. He has basically taken the discovery of scientists prior to him, who stated that insulin causes fat accumulation, and has made that ignored information known to the masses, and for his generosity, he is experiencing a backlash from those who uphold the prevailing orthodoxy of calories in vs. calories out. I guarantee you, that a generation from now, Taubes will be revered as a science revolutionary along with Atkins, Yudkin, and Lustig.
  • Taubes’s mention of General Mill’s donations to Harvard opened my eyes to the huge influence corporations can have on top research institutions. This is an unavoidable consequence of the fact that scientific endeavors require huge amounts of time and money. I am also surprised about the scientific validity of the Atkins diet and the examples Taubes used to counter popular conceptions of obesity e.g. the Fat Louisa paradox and early twentieth century research on adiposity.
