So fat people are ruining the UK because their lifestyle is costing the NHS millions (News Shopper, January 12).

Are they the only ones? What about drug takers, alcoholics and smokers?

Then, of course, there are the elderly, notorious for taking up beds in NHS hospitals, let alone the cost of their free prescriptions.

A healthy lifestyle can also clog up the system there are always plenty of sports injuries needing treatment.

Obesity is not always caused by fast food-scoffing couch potatoes but sometimes by prescription drugs which can cause weight gain.
