Deathly skinny would be my choice - I would not need to carry all this weight and would be less impaired in my personal mobility and keeping my personal hygiene easier for me especially. That would hopefully make me less socially isolated. Also just being deathly skinny is not associated with diseases like diabetes, syndrome x and so on for which I carry specific genetic risks. If not my deathly skinny-ness is caused by already existing consuming disease like cancer or infection that would also better chances to live longer with a higher quality of life. And - thinking of quality of life - I would not need to count my calorie intake like I have to do now…. I tend a bit to the heavy side and it is easier for me to gain weight than to loose weight so being deathly skinny is the lesser problem for me to solve.

But I have to confess that the morbidly obese persons I am thinking of are the extreme cases. I saw them during my clinical education and they already had resulting health problems of the severe kind and sometimes were too heavy for weighing on the normal hospitals scales.
