Exploited singer Wattie Buchan is joining forces with ‘the establishment’ to promote Scottish government anti-obesity measures.

The frontman of the 80s punk act was among a number of football fans present at Hearts’ Tynecastle Stadium, to launch a drive to improve the nation’s diet.

Buchan, 60, is a member of the SPFL Trust’s Football Fans in Training (FFIT) which aims to crack down on the advertisement of foodstuffs which are high in fat, sugar and salt.

Buchan says he has lost four stone since joining the programme. In February 2014, the singer suffered a heart attack – his fifth – during a gig in Lisbon.

“I was miserable before. I’ve had five heart attacks, I’ve had a quadruple bypass. My life was terrible. This is the best I’ve felt in four years, I feel better within myself being fitter.”

“Twelve weeks ago I could hardly walk. I’ve been doing this for five weeks and now I walk a lot – even my dog has lost weight.

“It’s totally changed my life around. It’s made a massive difference to how I feel; I feel better mentally as well. It’s like night and day; I am loving it.”
