There is a trend toward increasing FM% with increasing dissatisfaction by excess. <...> Men and women differ in body composition characteristics associated to their body image satisfaction, women being more satisfi ed with a lower FM%. <...> Body image dissatisfaction by excess tends to be related to FM% excess in men, while in women it seems to be more <...>
