I think the reason we are all fatter is because there is sugar in everything, literally. It's in ketchup for crying out loud! Studies show that when given a choice, infants prefer sugared water to plain water, and so do we, as adults. Humans are rigged to go for the sweet taste. The food companies take full advantage of this fact. The next time you're in the grocery store, look at various labels- you will see sugar in everything, just everything. That's why I think we're all fatter!
