Not any kind of expert here, and while I am normally anti-conspiracy theory and respect educated expert opinion, in this case I'd side with the PT. Anecdotally, eliminating starchy carbs (combined with lots of exercise) was my key to losing weight. I went from the perspective of glycolic index and foods that didn't spike blood sugar and cravings.

As soon as your dietician says that doctors only have to take one course about nutrition, you've got to start questioning her objectivity. Doctors have to understand a lot more than just nutrition including basic biology and chemistry.

I have heard similar things about lobbying influencing the food guide and there may be something to it, but my own take comes from my own research and experience. I think the food guide is probably fine for those who aren't sensitive to blood sugar fluctuations AND who work at physically intensive occupations, but for those of us that sit at a desk, have a lot of stress, and may be more sensitive to glucose variations, the food guide is just not appropriate.
