Retuning the radio from a channel we listen to everyday helps us get rid of our bad habits - and could even lead to weightloss.

Psychologist Professor Ben Fletcher says:

"Deeply engrained habits of thinking and behaviour keep us doing things that are bad for us, like smoking, eating and drinking too much or becoming stuck in negative thought patterns, all of which impacts on our health.

"We can make our lives so much better by making very small changes."
