A pound of fat is about 3,500 calories of overeating. Real hard to do that much in one sitting for someone who doesn't do it constantly.

3,500 calories of fat, or 30% extra of carbs or protein. protein is also insulinogenic so eating too much fat along with similar amounts of protein will make someone balloon (i.e fried chicken)

Yes but how much of those calories are you burning off every day ? - you would need 3,500 above your daily burn rate

That's what I meant by "overeating": whatever is beyond what you need to sustain.
