Below is a link to the latest article by Gary Taubes.
For those who haven't come across him before he is the author of a seminal book called 'Good Calories, Bad Calories' (The Diet Delusion' in this country)
His second book 'Why We Get Fat and What To Do About It' was aimed at the general public rather than the professionals his first book tried to reach. I have read both.
I'm posting the article as it is relevant to my postings on exercise and sugar.
The comments are interesting, especially the one by the overweight (despite his strenuous, energy expensive occupation) construction worker (Griff) who tried the low carb approach.
