I never snacked when I weighed 100lbs more, there are just too many damn calories in everything.

Jim you’re totally right. Our brains were wired for scarcity. We are not evolved to pass up sugars or deal with lookalike chemicals like opiates. The modern world asks a lot of our psychology to manage that.

Which is why I said "some". I know it's not the same set of problems for all of us ;)
