Men's Health interviewed and quoted me in an article titled "Reprogram Your Metabolism", written by Lou Schuler. Part of the article was related to the food reward concept. I'm glad to see the idea gradually reaching the mainstream.
Boing Boing recently covered an article by Dr. Hisham Ziauddeen and colleagues in Nature Reviews Neuroscience that questioned the idea that common obesity represents food addiction-- an idea that I often encounter in my reading. Maggie Koerth-Baker asked me if I wanted to respond. I sent her a response explaining that I agree with the authors' conclusions and I also doubt obesity is food addiction per se, as I have explained in the past, although a subset of obese people can be addicted to food. I explained that the conclusions of the paper are consistent with the idea that food reward influences fat mass. You can find my explanation here.
