Historical exposure to famine does not appear to have been an important factor driving the link between fatness and attractiveness.Dr Lobke Vaanholt, who organised the University of Aberdeen component of the study, said: “Although most people will not be surprised that extreme thinness was perceived as the most attractive body type, since this prevails so heavily in media, culture and fashion, the important advance is that now we have an evolutionary understanding of why this is the case.”Professor John Speakman added: “I am delighted to have been involved in this international collaboration that has revealed evolutionary aspects of what people regard as attractive across diverse cultures. credit by exam that is accepted by over 1,500 colleges and universities. One idea about how we rate physical attractiveness is based on the impact that different aspects of our bodies (like body fatness) have on evolutionary fitness.

If they’re no longer reproducing then they are no longer evolutionarily fit. For example, we know that above a certain body fatness females have greater risks of chronic diseases like diabetes and heart disease, and lower fertility, which might make fatter subjects less attractive.
