Which Candy Bar Is Isner’s Lucky Charm At Wimbledon?

John Isner, the reigning Miami Open presented by Itau champion, has made the best Grand Slam run of his career by reaching the Wimbledon semi-finals, where he will face eighth seed Kevin Anderson. And while winning all 95 of his service games has certainly helped at the All England Club, one sweet treat might be the secret to his success, and it’s not an amino acid, a power bar, or anything you might guess.

“I just had a Kit Kat before I came in here. That’s the truth,” Isner told reporters with a smile after his quarter-final victory against Milos Raonic on Wednesday. “I had a little bit of a sugar craving. That’s not a normal occurrence for me. I think after each win throughout these 10 days, I’ve had a Kit Kat. I’m not going to change that now.”

The American hopes that on Friday he’ll be able to continue that streak. And while he has been indulging himself this fortnight, the 33-year-old says he has generally been careful with his diet.

“Especially when I started learning more and more about how important nutrition and diet is, I’ve always eaten very well,” Isner said. “I still eat a lot. I have such a big frame. But for the most part I know what to eat. I don’t eat much pasta. I never eat pizza. I don’t eat much unhealthy stuff. For me, in large part, I’m putting really good fuel in my body.”

The one irony of this story is that Kit Kat’s slogan is, “Have a break, have a Kit Kat’. Isner will be doing his best to ensure that, for the sixth consecutive match this fortnight, there won’t be any breaks – of his serve – against Anderson.
