Remember all that well-meaning guff about an Olympic ‘legacy’?

It was never clear how spending billions of pounds - money that could have been given to bailed-out bankers, say - on a herd of architectural white elephants would make even a single wheezing chubber less fat. But Lucozade Revive offers hope of a path.

Trade in the neon-orange hangover-killer that is GSK’s flagship glug for the sparkly green stuff magically wafting about here and you’ll be pirouetting like a pair of Bolshoi swingers in no time.

Even if it does make you look like a prat.
