Wait a minute... since when have women liked fat guys? I've found that women that
prefer heavier-set guys is much more rare than women that profess to like lean men.
Anyway, I'd probably place the most blame on sweets. Damn, some of those sweets are
really fucking good, but holy shit, they are really unhealthy! I look at some of the things that I used to eat such as Chewy Chips Ahoy!, and I pretty much look like this

when I read the nutrition labels. You know it's not good when they have maybe ~100-150 calories per serving and the serving size is only a few cookies. Those things are so small, I could eat rows of them. :$
It's not only sweets though. It's really easy to miss how unhealthy normal items are.
