This is what Jooheon really said during the SBS R-Powertime interview about his secret to dieting (watch HERE around 32:00).

When he said “you just have to starve,” he was actually referring to the late night snacking that he gave up in order for him to lose weight.

So whoever screen cap the previous caps really took it out of context, to make it seem like Jooheon doesn’t eat at all. He just doesn’t eat late night snacks like ramen. There is no way in hell the members would let Jooheon starve.
