Improving your attitude to body image is possible. Sandra Comer suggests:
Stop weighing yourself. It can become compulsive and dictate the kind of day you have. Get rid of the scales.
Reject comments about your body. However well intentioned the comment - 'I see you've lost weight' - may be, it conveys the message that the speaker has been keeping an eye on your weight. Your body is your private concern.
Identify what triggers negative feelings about your body. It could be an argument with your partner or being ignored in a social situation.
Find physical activities you enjoy. Exercise for the sheer pleasure of your body moving.
Confront your own 'weightiest' attitudes and recognise the genetic diversity of body weight and shape. Be forgiving about other people's bodies. Try to find three attractive things in every woman you see.
