The fastest way to strip a woman of her power is to put her at odds with her body.
Tell her lies about her softness being weakness, Her intuition being untrustworthy, Her appetite - dangerous.
Tell her she needs to follow an external authority over her internal knowing. To question her needs and deny her wantings. How she feels is not as important as how she looks.
Tell her starving herself is strength, Taking up less space is power, Being looked at is more important than being heard.
So society gave women dieting.
