Peter Miller has watched Rodtang “The Iron Man” Jitmuangnon through the highs of a five-year reign and the lows that followed. Heading into the biggest test of his comeback, the nutritionist insists the Thai megastar has never looked better.
The 29-year-old former ONE Flyweight Muay Thai World Champion finally meets Nong-O Hama in a quarterfinal of the ONE Flyweight Muay Thai World Grand Prix at The Inner Circle 38 on Friday, November 13, at Bangkok’s Lumpinee Stadium. Their original showdown at ONE 173 in November 2025 collapsed when Rodtang fell ill shortly after making weight and passing hydration.

It has been a turbulent stretch. Rodtang lost his crown after missing weight for his November 2024 bout with Jacob Smith, then suffered a fifth-round TKO against Takeru Segawa this past April.
Miller, the man behind Condition Nutrition, has seen a very different athlete during this camp. Rodtang has followed every part of the plan without fail.
“He’s trained really hard. I couldn’t be happier with the discipline and motivation he’s had. He’s been following his diet plan, he’s been following his training plan 100 percent. So, it makes my job really easy,” Miller said.
“He’s very motivated, and I can see that in him. His mood and enthusiasm for this fight are probably the best I’ve seen, so I’m very happy.”
That shift in attitude matters against an opponent like Nong-O. The former ONE Bantamweight Muay Thai World Champion defended his belt seven times before dropping to flyweight, and a win would push Rodtang a step closer to reigning king Asadula Imangazaliev.

Miller has built a close bond with the Thai over the years, which makes this version of Rodtang especially satisfying for him to witness.
“This time, it’s like a new Rodtang. He’s motivated. It’s like a new beginning for him, and it’s really happy to see because I’ve got a really good relationship with him,” he said.
Thai fans have long adored Rodtang’s aggression and durability. Miller believes they are about to see the best of both on November 13.
“I think the Thai fans are expecting a new motivated Rodtang now. A new start, a new beginning, a happy Rodtang in a good place physically and mentally,” Miller said.
“He’s coming for the knockouts, and I am pretty confident he’s going to do that.”
