Ha ha, I'll bite (no pun intended). If you eat six 200 calorie brownies a day (and nothing else) and your daily calorie burn is 1700 calories you should, theoretically, and on average, lose one pound in a week. I won't say that the nutritional mix doesn't matter at all and I don't think it's a particularly healthy idea, but I'd guess (like the guy who ate Hostess desserts) one coiuld lose weight that way.
