Chocolate as a slippery slope?

A new study reports that allowing one indulgence, such as a chocolate truffle, can lower one’s willpower and lead to a desire to eat more.

I think it’s an attitudinal thing – you can eat one truffle and think, “Well, I’ve already ruined my diet, so I may as well have more and eat well another day.” Or you can eat one truffle and think, “That was a delicious treat that, in moderation, can be included in any diet. Because chocolate should be special, I’ll stop at one and allow myself another tomorrow.”

Well, maybe not verbatim, but you get the idea.
