In the UK, over 60 percent of people are overweight. Medical experts say that obesity is a leading cause of preventable deaths which costs the health service almost $8bn every year.
Should people who refuse to stop smoking, another leading cause of diseases in the country, or who are grossly overweight receive medical support?
That is a question being asked increasingly in the UK, where the National Health Service is struggling to cope.
