I don't completely agree, but see your point with this post. I just think this is meaning to say the bulk of your caloric content should come from more satisfying sources and fruits and other sugars should just complement them.
Sure - biologically it makes no sense to crave sugar 365 days a year, when the vast majority of the time fruit isn't around. I think that most people will stop craving sugar if they just stop eating sugar for a few weeks. That's certainly how it worked with me. I went from 7-10 soda cans a day to 0 - haven't had one in like 8 years or something and certainly don't spend all day craving sugar. I could go for some chicken right about now though. :)
