I agree that palatablility is a part of the equation and may explain why we started eating sugar, but it doesn't explain why I was attracted back to the half gallon of icecream when I had a cold & couldn't even taste it. And the spikes & troughs in my bloodsugar could be directly correlated with feeling hungry an hour or two later. Also, I find steak and bacon to be very palatable and can eat 2-3X more than necessary, but they don't make me fat and diabetic.
