The trainer went on to reveal exactly how the TV chef made the impressive changes - and it involved some hardcore training sessions.
"Manu and his wife Clarissa started with five x 45min DARC-based sessions a week. Each session combined functional resistance training (Kettlebells, Landmine, Dumbbells, Body Weight etc) with HIIT. He would do three to four strength exercises with me, then three to four intervals with Emilie, before head back to me," he said.
He also revealed how Manu changed his eating habits, ditching "all alcohol, processed sugars, and starchy carbs, while increasing his intake of green leafy vegetables and lean meats."
While he said Manu usually sticks to a simple eating plan, his MKR commitments sometimes got in the way.
"When he’s judging MKR he is required to taste every dish presented by the contestants. As you can imagine, these types of dishes were more often than not either quite rich, or particularly sweet etc," the celebrity trainer added.
Manu is clearly impressed with his results, and took to his Instagram on Wednesday to show fans his weight loss.
"MKR series 10 vs MKR series 11, no words needed," Manu captioned a side-by-side photo of his impressive results.
