Body image and obesity is a personal issue. I am obese but mine is not due to over eating as I have been told to eat more by medical professionals. Mine is due to depression and mental health issues. I have had years of people 'poking the bear' as Piers would say, but it makes things worse. I have tried and tried to lose weight but the bullying still continues and you can feel worthless. But there are people out there that celebrate their bigger size and good on them. Confidence is taken away from you with constant 'poking'. Piers and his brothers may find this works for them but Piers has to remember that what works for one doesn't work for another. He can have his views but don't push them on others.
Fat shamming is an issue and visa versa with saying people are too thin. Everyone is individual and maybe we should all remember that .
