I used to weigh 25 stone, but the responsibility for the obesity crisis is as much yours as it is mine

I used to weigh 25 and a half stone. Thanks to weight loss surgery and the Slimming World programme, I am now around 13 stone – and aiming to make it to 10 and a half.

In my old life, I couldn’t walk 100 metres without crippling back pain. Last month I hiked 25km for charity, and up some pretty steep hills too. I have gone from being morbidly obese to obese. Soon, I hope, I will just be overweight.

And then, one day I will be a healthy weight.
