As a former anorexic – think Portia de Rossi – I am 5'6″ and at one time I weighed 86 pounds and I exercised to excess. Don't emulate the 'big six'. Extremism, whether in diet or exercise or religion or politics is not good for your health. Yeah, in our secret hearts none of us measures up. Ignore the sneaky messages your secret heart sends to your brain and do your best to be healthy. Why does this stuff scare me? Why does it piss me off? Because I have two daughters, that's why. I don't want them influenced by this crap.
