The teenager, from Renfrew near Glasgow, is so worried about his appearance that he photoshops all of his online profile pictures.

Almost a third of 2,000 UK teenagers, polled for a body confidence campaign, avoid activities like PE because of fears about their looks.

The Be Real Campaign says schools have a key role in combating body anxiety.

Fears about they way they look are "having a profoundly negative effect on a significant number of young people in the UK", says the report.

The research has shown a strong connection between sleep deprivation and higher body weight, both in adults and in kids.

And perhaps the most striking connection is that the one may predict the other as a person ages: In fact, a new study in The Journal of Pediatrics finds that the later the bedtime in early childhood, the greater the risk for obesity in adolescence.
