Obesity disease mongering?

Obesity concerns may be just another example of medicalization according to Dr Hamish Meldrum, head of the British Medical Association. According to This is London:

Obese people are often simply greedy and should not always be treated with pills, the head of the British Medical Association has said. Dr Hamish Meldrum believes an obsession with medical labels may be stopping overweight people addressing their own problems. He said the obesity epidemic is being mistakenly targeted with medical treatments and doctors' appointments.
