He's best known for his radio segment with close mate Andy Lee, but Hamish Blake has recently taken the fitness industry by storm.
Following in the footsteps of other fitness influencers, the new dad posted about his body transformation on Instagram following the completion of his new #5minutefast challenge.
The 35-year-old captioned the before and after pictures: "Just completed the #5MinuteFast, an exciting health fitness trend I invented today! The goal being to see if you can do 5 minutes with zero food whatsoever, not even nibbles or snacks."
"I was excited to do it but after the initial thrill wore off I have to say I found the middle 200 seconds challenging, and had to dig deep and think about all the cleansing my body was doing, despite my raging hunger.
"With 30 seconds to go I just tried to hang on for dear life, and as you can see at the end, I was overjoyed. Felt a lot lighter, very clear headed and so proud of myself. Look forward to doing the #5MinuteFast again and not cheating next time! (Had a bag of chips at the 2 min mark, but I was feeling VERY faint). Try it yourself and let me know if you made it in comments!!"
Fans were taken back.
"Impossible," wrote @jordan_lea.
Another user, @adelaide_paternoster, commenter, "My type of hero."
@chelle1811 asked Hamish, "Are there any workouts you'd recommend to complement this regime? Excited to see everyone's before and after shots #5tothrive."
Although some questioned whether the method was realistic.
"I dunno if I can do it," wrote @chelsea.christina.
But we're willing to give this revolutionary diet a try.
