The first row shows CHANYEOL during his bulking era, while the 2nd is him currently. A lot of people completely misunderstood his comments because they didn't realize he was talking specifically about the period right after his military discharge up until black out era.
When he used the term “bulking up disease” he wasn't talking about a real medical condition. It's just a common Korean slang expression that international fans are understandably unfamiliar with, it used to describe an obsession with overexercising and the mental fixation on getting as big as possible. This mindset can easily lead to extreme physical burnout & overeating during the bulk, which ends up hurting your health.

So when CHANYEOL said he “intervenes to stop the members from over-bulking” he just meant he doesn't want them to fall into that SAME TOXIC cycle of obsessive working out like he did. It has absolutely NOTHING to do with weight loss or dieting; it was purely coming from a place of concern and good intentions.
CHANYEOL is well-educated when it comes to nutrition and fitness. He maintains a perfect balance and a healthy lifestyle, and he has NEVER once promoted unhealthy habits. He knows exactly what’s best for him and how to take proper care of himself.
