While parts of the body do operate according to the golden ratio, do we have reason to believe that making your body conform to it makes you more appealing? As the second link makes clear: the golden ratio showing up in our bodies is cool, but these ratios are not directly related to what we find attractive in the opposite sex.
If there were an ideal shape based on the golden ratio, wouldn't both males and females be attracted to the same body shape in their lust for the same ideal ratio?
