What duping? Was he was duped, or does he dupe people?
Roughly 10 months ago, Robb Wolf posted the first installment on his "current" views about carbohydrates in the diet: Low Carb And Paleo: My Thoughts Part 1. In it, Robb describes his changing views on dietary composition and body composition through his personal prism of going from highly active, running a gym, etc. to a more sedentary lifestyle involving lots of writing time. As he relates:
I had a tough time remaining lean. I’d cut carbs…but to no effect on body composition. Slowly I realized, both by experimentation and by really looking at the literature: CALORIES MATTERED MORE THAN CARBS FOR BODY-COMP.
I have to say this was a pretty big shake-up for me. I’d assumed one could eat as much fat as one desired and STILL get leaner.
