My fat mom too! "Oh I just eat all the insides of the pie, not the crust so it's healthy", or, "Peanut M&M's are ok (by the bagful) for diabetic people because the peanuts cancel out the blah blah blah".  And then she'll come to me desperate for tips on how to lose weight, I tell her to count her calories, and she always goes, "no." I think she keeps expecting me to give her a different answer, an easier one, but that doesn't exist. I literally cannot even, guise.
