Read this article by Taubes. I actually strongly recommend his book.
From a scientific point of view, it’s getting very clear what is going on. Just like the “global warming scientists” (an oxymoron), the AHA and others have been tragically wrong. I think it was far more deliberate with the “global warming scientists,” but they both let their pre-conceived notions and strong “trendy” beliefs dictate what they saw, how they interpreted those observations, and how those results were reported.
I’m waiting for an apology, but I will wait forever. I’m not holding my breath (that would be exceedingly unwise).
Let me tell you a little story. For the last 20+ years I’ve struggled with weight. For years I was very faithful in working out, often getting up at around 4:30am to go do it. I worked hard and I was very dedicated. I did many bouts of semi-starvation. I gained and lost pounds many times (the same pounds). I was then diagnosed with Multiple Sclerosis and I found that physically I just couldn’t do that anymore. I could ride an exercise bike, but that was about it. And to do even that really strenuously would lead to significant symptoms. So I had to change.
After about six months with Taubes’ approach I lost just over 40 pounds. Only 10 or so more to go now. I still ride the exercise bike pretty regularly, and I think there is good evidence that frequent exercise changes the way energy is metabolized in beneficial ways. But it is quite clear to me that a high-carb, low-fat diet is a recipe for obesity.
