Hi Windrider,
I don't know whether you checked Ben's profile, but I noticed he is a chef by occupation. In general, I don't think of chef's as those most prone to popping into the nearby gas station for jerky or eating pre-packaged meat and fish products as staples whilst attempting to lose weight. Although I agree his diet didn't sound balanced, the lack of fruit and veggie content does not equate to hidden starches (to me at least). Perhaps he will jump back in and provide us more details, otherwise your conclusions seem a bit of a leap.
A chef with a weight issue doesn't lead me to conclude.. 'something is amiss in how his body transfers food into flesh' ...when a simpler answer might suffice?
