BMI and physical attractiveness Boy oh boy do i have a gem for you, a study on BMI and attractiveness, https://files.nyu.edu/dc66/public/smr_bmi.pdf  and the bias associated with it according to region,race,age and some other factors, move to page 21 for the full list, to put it simply column one is the people giving a socially desirable answer compared to those in column 2 answering truthfully, the difference in column 3 is the social desirability bias Some conclusions we can make with this study (keep in mind, to do this study they used 2 pictures of the same person, their normal picture and the digitally modified one, the difference is noticeable but not that big, if the difference was bigger we'd probably see much more interesting results) see page 13 for the comparison Long post and some conclusions might be wrong but i still find it a good study where you should be living to maximize that thin privelege
