The former Westlife singer was crowned the winner after spending three weeks in the celebrity camp and as well as taking on the role as camp chef, Kian also won twenty meals for his fellow campmates and was often the voice of reason when tensions were high.
But he told Phillip and Holly that while he thoroughly enjoyed his time in the jungle, there were a few days when he was just not himself.
"I did have two really down days in there," he admitted.
"The first day was about a week in and I was just at a point where the lack of food had gotten to me and I just didn't have enough energy but by the time the evening came I had kind of picked myself back up and I was back in it.
"But then with about a week to go I had a really bad day where every time I stood up I would get a head rush and I would have t sit back down and people would be quite concerned about me.
"So (the producers) called me up (to the Bush telegraph) and they asked me what was wrong and I told them I genuinely thought it was just a lack of food.
"My body was shutting down because we were only eating about 500 calories a day.
"So they gave me a herbal vitamin, or something like that, and by the next morning I was back to normal."
The star also explained that he would have only ever considered taking part in I'm A Celebrity because all the other reality shows were "not his thing".
"When it comes to the dancing shows or any of them other shows, it's not really my thing whereas (I'm A Celebrity) is my thing.
"The adventure, the jumping out of helicopters anything like that, none of that stuff really bothers me; it's all an adventure to me."
Kian also admitted that before heading to Australia he did try to get himself ready both mentally and physically for his jungle experience.
"I went to the gym and I tried to get physically fit and I tried to bring my food intake down... to try and shrink my stomach a bit, until the last week when I realised I was really going (into the jungle) and I was like "oh, there's a pizza, I'm not gonna have this for another few weeks so I'll have that".
"But I don't think there's anything you can really train for to actually do it."
