If they have a relationship with a food that is out of control and eat it to excess... it's not the food.
That person should avoid that food. Not really try and tell everyone that THAT specific food is fattening because "I can't control myself around it."
This is a YMMV situation if ever there was one.
Lots of people use coconut butter in moderation.
Even just on rare occasion like I do.
I don't find it fattening at all.
