Being fat isn't a single bad choice. It is the result of countless, tiny, bad choices just like this  Exactly. I still read 1200isplenty on reddit. And that more than almost anything else really drives home that a lot of people on there were, or even still are, fat. One of the more common and annoying pieces of advice is that one day of excess won't make a difference. But people seldom seem to understand that it's seldom 'one' bad choice. Just totaling up every holiday or event in any given month can create a pretty intimidating total for even minor exceptions to the rule. Add in things like this and people's every now and then indulgence turns into a huge problem.
