Dr Micheal Mosely is known for his fat-shedding diets, but some may not realise that part of his inspiration to create these weight loss plans come from his own struggle with type 2 diabetes.
The doctor has had many careers, starting out as an investment banker, then retraining in medicine at the Royal Free Hospital in London before finally working at the BBC for more than two decades.
He began as a trainee assistant producer at the broadcaster and became an experienced medical journalist over the years with many of his own series.
