Diets causing more harm than good, says health psychologist
Diets are causing more harm than good, according to a health psychologist who says the Welsh government should stop advising people to lose weight.

Tim Rogers reports.
The full report will be on Week in Week Out on BBC One at 22:35 BST on Tuesday, 15 October.
