I was drawn in hook line and sinker when my fellow foodie, breakfast partner and best friend suggested we transform our selvesinto Miranda Kerr-like beings with the 'Master Cleanse'.

We know celebrities shape our attitudes towards body image but they also affect the way we think about losing weight. And not in a good way.

Sometimes it's hard to be a celebrity. Yoyo dieting (a cycle of losing weight and then gaining it back) is very common, but it is of course much worse when it's played out in public.

Whatever changes you make need to be sustainable. You need to be willing to do them for the rest of your life. Make it easy, make it enjoyable. And be patient. Dawn French didn't lose her weight overnight, and you don't need to either.
