"I had this idea that food was something that people didn't want me to have, so if I wanted to have more, I needed to do it privately, and it became something I was witholding from people," he said.
"I actually realised later in life that much of my binge eating came on my own. When I was a teenager I would go out to a nightclub with my friends, and never really felt comfortable eating in front of people, but on my way home I'd always find a 24 hour drive-through and eat three whole meals right before bed."
Suplee overhauled his diet, reducing his calorie intake by 20 per cent while including more filling, protein-rich foods such as turkey and non-fat greek yoghurt.
Meanwhile, in the gym, he now trains six times a week while following a push-pull-legs workout plan.
He hasn't just shed the kilos. In a recent Ask Me Anything on Instagram, Suplee revealed he can now bench 180kg, describing it as his "proudest lift."
