Probably not the best wording. It's a personal health risk, and if the UK is like Canada, more and more people are becoming overweight, which leads to increased chances of developing problems from weakened immune systems, high cholesterol, high blood pressure etc etc, which leads to strokes, cancer.......etc.

Not sure how healthcare works in the UK specifically, but in Canada it's all covered by the government. Health complications coming from an increasing overweight populations here are costing the government millions and millions a year. It really is a quite serious problem.
