Gary Taubes gave a lecture entitled "Truth and Lies About Fats and Obesity" at Berkely and then repeated the lecture at a few other venues. Food Renegade embedded the video from Severins in this post:
His book, Good Calories, Bad Calories, is excellent, but some people don't have the inclination to read a 400 page book with 200 pages of references and footnotes. I admit, it's intimidating.
It's also THOROUGH. When you are trying to reverse a nation-wide dogma 50 years in the making, it's good to have basically all the evidence on your side. But most people who read this book already have an open mind about it, or they'd put it down after the introduction, so sometimes there is such a thing as TOO MUCH evidence.
So for those intimidated or uninterested in a 640 page tome, he's managed to condense most of it into an hour long presentation (with pictures!). He addresses the diet-cholesterol-heart hypothesis which is the subject of his book, and he also addresses the energy balance (calories in, calories out) hypothesis. It's a great lecture, but then again, I'm a sucker for a well-presented, clear, logical argument.
Set aside some time to watch it and let me know what you think.
