We live in a body-conscious society, so it's not surprising that every now and again we decide to do something to boost our confidence and help us feel in control.

But obsessing over food or becoming too concerned with our body image puts our physical and mental health at risk. For instance, in UK it is estimated that around 165,000 people are currently being treated for eating disorders, with many more remaining undiagnosed.

Anyone can develop an eating disorder. Women between 15 and 25 are most likely but a growing number of young men also suffer.
