When I was a kid growing up in New York City in the 1980s, a new television star was making waves. Oprah Winfrey had burst onto the scene with her day time television talk show but much of the focus was on her weight.br br Oprah spent the next few decades openly sharing her struggles with weight loss as the world watched her go from diet to diet, going a few sizes down and then up again. Her body was being scrutinised all the time.
