I truly think the problem with all the people offering us "just one won't hurt" is that in the back of their minds have the calorie mentality. If you eat just one you can make up for the extra calories tomorrow. They don't understand, or they don't know, that this woe is not about "a few more calories" but hormone/blood chemistry that may take days or weeks to get back to good levels after eating the "just one won't hurt".
