I'd go with "possibly real", there are so many deluded fat people proud of being fat, guys think theyre big as in powerlifter big, and girls think they're curvy as in Sophia Loren curves, and for the portion thing, 100% real, I'm a short girl and if I'm not exercising my TDEE is quite low, if I don't pay attention I could get to mini moon status real quick, I'm not restricting, I just eat reasonably, but I can't count the number of "omg u starving, u eat liek a birb, go eat sumthin" so yeah, definitely feasable
