I’m naturally a size 6. I don’t really exercise beyond walking about 50% of the places I go and eat within my calories by making fresh meals for at least 2 of my 3 meals a day. Decades ago a lot of people could be that size naturally but the access to super processed foods has made people eat poorly and put on excessive weight.Do u think she doesnt? No one is naturally that skinny. There is no stretch of the imagination to link her current size to an ED.
