Good post crikey, and I understand and agree.
However my post was really meant to say that whilst many people don't take responsibility, many do and STILL fail. Many people have genuinely tried and failed to overcome their vices and habits of a lifetime. It can be really very difficult.
Rather than castigating those who have failed, which is what the "just ELMM fatso it's easy" message does, it's better to help people help themselves. Dietary advice will do this if it can be put across. So will intelligent legislation.
