Doctors in the UK are getting plastic models of fat blobs to show their patients. (Yes, seriously).
When I was 10 or so, I recall my family doctor showing me one of these plastic models. It was very hurtful. I really don't understand how the message can be anything other than "This is disgusting. This is part of you. Thus, you are disgusting." I already wanted to lose weight; it had been my New Year's Resolution for years, and part of my daily life for even longer. This experience just added more shame and more pain to being a fat child.
Experiences like these with doctors are a big part of why I chose to study medicine. There are better ways to motivate people, and better ways to promote health. One of my dreams is to one day open a multidisciplinary primary care health clinic based around Health at Every Size principles. Fake fat won't be allowed on the premises. :-)
