YouTube - ‪The Battle of the Diets: Is Anyone Winning (At Losing?)‬‏
I really, really enjoyed watching this presentation. It's from 2007 and was uploaded in 2008, and I don't know why I found it only last weekend.
The main take-away message is: Low-Carb seems to work much better for people who are insulin resistant - determined by either fasting glucose levels or triglycerides/HDL ratio - while low-fat seems to work better for those who aren't.
Even though I don't think I eat high fat (not a fan of fat "slathering", well, sometimes when it's merited) I don't think perpetual low fat works for ANYBODY. Moderate fat, which is what I reckon you get when you don't purposely avoid fat, but don't seek it out at every turn (ie: me) is what has worked the best for me.
A constant low fat state would wreak havoc for me, and I bet it goes for most.
Low carb is good for the vast majority, especially overweight folks and sedentary folks. I "need" my starches for my workouts and because I love to eat them. I don't mind having one to three "low fat" days a week for that reason.
One other point made in the presentation was that people had a hard time adhering to either extreme diet (Atkins, Ornish). The latter is about as low-fat as you can get, but people ended up with almost 30% fat, if I remember correctly. If that's all healthy fat (little poly-unsaturated, no trans fats) I think it's quite possible for many people to do great on such a diet. Provided of course, as I mentioned above, that they're not prone to insulin resistance. If we further assume "clean" carbs (no wheat/gluten/lectins etc.) I think such a diet is even compatible with a true paleo or paleo-equivalent approach.
Maybe I just don't come out from my rock enough but I don't see that many paleo type folks advocating VLC (sub 50gr per day)....
It seems to my like people are desperately trying to paint paleo/primal as a zero carb cult despite the fact that most paleo folks aren't really VLC and don't think carbs are teh debil.

I still want to know what supports "low fat" for weight loss. Taubes perceived defects is not an reason to do the opposite thing.
Why "rather"? Certainly it would be interesting to know more about why some people's tolerance to carbohydrate is higher. It's most probably genetic variation. And, as it happens, I only just read Taubes's Good Calories: Bad Calories, and he's perfectly clear that there is a great deal of variation.Rather than focusing on carbs as the *cause* for obesity, we should try to find out what makes some people react worse to carbs than others.
