It's not enough to have room in your diet for a full combo meal at McDonald's, oh no...they need to supersize it and get a milkshake in addition to soda.  And then an hour later they'll be eating candy bars.  They're too lazy to make dinner, so shocker they're calling out for pizza delivery..but you can't just get pizza.  There's a coupon for breadsticks and wings plus soda, it'd be a waste not to order it! And if you order it, you have to eat it of course.  It won't taste as good tomorrow. I typically leave half my calories for dinner, about 1200kcal.  I don't even know why, but I eat progressively more at each meal.  It's very easy for me to have a giant dinner, feel very full..and not even meet my calories for the day.  Your entire day can't be one buffet trip after another.  What's the shocker when they eat til they have meat sweats that it's too much?
