    Great article.
    I was wondering about obesity and overweight as its always been a confusion. My personal BMI is actually always around 26 meaning overweight but I am actually not in terms of physical image. I did try and go down to the normal BMI but seriously I looked anorexic and people asked if I was ill.
    A very interesting article and certainly one everyone should read – just for the health benefits of having a good weight alone!
