Chris kicked off the outing after letting fans know about his extreme weight loss secrets.
The Virgin Radio breakfast presenter has admitted he sometimes fasts for up to 16 hours to lose weight.
On his show, the host opened up about his extreme technique after a member of his team gave him a brownie cookie.
He said: “I did it for 12 hours fast and I never talked about it on the radio.
“But I don't eat for 12 hours a day because it improves everything. 16 hours is even better, but 12 is easy, especially if you do the breakfast show.

Chris revealed last month he was down to twelve stone after “changing his life” with a “super tip” to avoid alcohol with meals.
The star explained that he was down to twelve stone by avoiding alcohol with his meals.
He said on his show: “I've been doing this since Saturday and it has changed my life. Fluids, especially water, interfere with your digestion.
Forty-five minutes after a meal you really want to drink, and if you eat four or five hours apart, you drink water in between, which keeps you feeling full.
‘It helps with your digestion and weight loss. We encourage our kids to drink a glass of water with dinner, but it's actually the wrong thing to do.
After he lost weight, Chris revealed he wanted to freeze his ‘moobs'.
After chatting with Dr Ranj, he jokingly decided to undergo the surgery as he complained that he was still carrying a heavy weight on his chest.
Chris told Dr Ranj that he is currently measuring his testosterone levels in an attempt to increase them and that despite his great shape, he is still struggling to shift weight in the chest area.

He added: “I was watching villains this morning. I ran a marathon ten days ago and my emotions are in full swing.
‘That must be estrogen, no? What's going on here?'
Ranj then explained: “It doesn't have to be just estrogen. But you know what, you can fix them. You can freeze them if you want.
But Chris seemed to agree with the idea, replying: “It's cold in here, I just froze my ass off this morning.”
