日记：
Today is supposed to be my binge day, and that means I can eat whatever I want without worrying about my belly fat. But I don't think it works out for me since I just feel too guilty to even have a tiny bit of a cupcake. Besides, I don't think the fitness fanatic will have an appetite for any high-calorie snack either, especially when they've just finished a session and sweat like a pig. At that point, the last thing you want to do is to break your fitness streak over something as dumb as this. So I decide I will stop having a binge day and just keep up the good work.
