"There's no free lunch. You have to put the work in. You know, I've never felt better than the times when I've sacrificed alcohol and bad food," Statham, who is dating 22-year-old Rosie Huntington-Whiteley, said.
"You give all that up and you train extremely hard. It releases so many good endorphins. You feel so clear and there is no substitute for that feeling. I don't know why everybody doesn't do that because it really is the best you could ever feel when you're eating clean, living clean and training hard," he added.
In his upcoming film 'Safe', Statham brings a gritty, haunted intensity to Luke Wright, a former New York Police Department officer-cum-second-rate cage fighter, whose wife has been murdered and his life destroyed by the Russian mob. The film releases May 4.
Statham says people should not forget about their health during festive season.
"Come Christmas time, that all goes away and you go 'Oh! It's Christmas and it's time for a celebration!' And then you gorge and indulge and you feel like crap. You need another catalyst to go, 'Right, clunk, that's it, I'm going to start fresh again.' People need to set a goal," he said.
