Daley said that his coach labelled him fat during his preparations for London 2012 earlier this year, a jibe which pushed him to a new level of dedication.
He told BBC Sport: "To see Alexei Evangulov, the national performance director happy now... at the beginning of the year he was telling me I was fat.
"I've lost seven-and-a-half kilos, I've had to make so many changes. Now I can't wait to go and eat what I like."
Evangulov also shared that he had a bet with the Team GB divers that he would shave his head if they won a medal at London 2012.
In his own words, Evangulov "will be bald tomorrow" thanks to a brilliant performance from Daley.
