What can we do to stop young girls from focusing on their body image > brain?

Change society. Society values body image & athletic prowess over mental & artistic capability. Until society changes its priorities, we will continue to struggle in raising our children to value their brain over their brawn. But for those of us w/children, we should make every attempt to praise their mental & artistic achievements and encourage more of the same but not at the expense of obesity. Balance is key!
Encourage, Teach. "encourage girls to develop their skills and interests in other areas. Educate them on the manipulations of the advertising industry. Teach them to love themselves and encourage a focus on internal standards of beauty.” source: psychologist dr.
