Quinton Jackson Says He Has A Thyroid Problem

In an interview with MMA Fighting, Quinton “Rampage” Jackson revealed he was diagnosed with an underactive thyroid (hypothyroidism), which makes him gain weight faster than normal. Here are highlights:

On the diagnosis: “I’ve been dealing with this for like a year. I’ve been keeping it kind of to myself. It kind of bummed me out. If I don’t stay on top of it, I gain weight really fast. That’s what’s been going on. I’ve been noticing after my fights I’ve just been gaining more weight fast, I didn’t know what was going on.”

On making 205: “I think I’ve gotta change my lifestyle, change the way I eat and stuff like that. Then maybe I can make 205.”

On fighting at heavyweight: “I don’t really want to fight the real big boys, because I noticed that I tried to pick Ishii up at the end of the fight, I was trying to go for a slam and I was like, ‘This dude is too big’. He felt like he had put some bricks in his ass or something. I don’t know if it’s his judo background or what. I was like man, maybe I do need to take my ugly ass back down to 205.”
