On September 13, Daisuke Motoki (54) posted a photo to Instagram taken during his appearance on Nippon TV’s “Sunday PUSH Sports.” His noticeably slimmer frame drew a wave of surprise and concern from fans, with comments like “Have you lost weight again?” He is said to have dropped 23kg from his playing days, and it was also reported that a doctor had previously told him he was “basically diabetic.” On 5ch, posters shared their own experiences losing weight on diabetes medication and debated how bodies change with age, with worried reactions mixing with more matter-of-fact takes.
On September 13, Daisuke Motoki (54) — a former professional baseball player and coach for the Yomiuri Giants who now works as a TV personality — updated his Instagram with a full-body shot from his appearance on “Sunday PUSH Sports” (Nippon TV).
Motoki wore an autumn-appropriate outfit — a dark brown zip-up jacket, beige pants, and sneakers — that showed off his noticeably slimmer frame. But fans who saw the photo responded with surprise and concern, with comments like “Have you lost weight again?”
Maybe if he took up yoga and became buddies with Tsurutaro Kataoka, nobody would worry about him. (Kataoka is a Japanese actor famous for his yoga practice and lean look well into his 60s.)

Looks like he's dieting without any exercise.

He dropped weight fast after Ohtani glared at him, didn't he?

I wonder if he actually got a diabetes diagnosis. If so, that's great news — it means insurance covers Mounjaro. I got diagnosed with type 2 diabetes myself and lost 25kg in six months on Mounjaro. People I haven't seen in a while are shocked when they see me. Sure, it might age your face a bit, but all my bad bloodwork numbers improved and my fatty liver cleared up, so health-wise it's a win. Looking older is a small price to pay for that.

Lately even his commentary sounds like his brain isn't keeping up, it's honestly a little scary to listen to.
He really needs to eat more.
20AnonymousSep 16, 2026 00:30
Looking older… well, he's 54, isn't that just normal?
This is about the right look for his age.

He looks like a 68-year-old grandpa.

He looks way too unhealthy for a 54-year-old.

Look at the fifty-somethings around you.

They look younger than that.

So even though he has a wife, he was the one eating however he wanted? If he were single, a messed-up diet would make more sense, but…

Re: #30
It's not like he's a salaryman — he probably doesn't eat at home that often.

His hairstyle always bugs me, it looks like something out of a Drifters comedy skit. (The Drifters were a legendary Japanese slapstick comedy troupe.)

My blood sugar's at 240 too, I guess I should follow his lead.
38AnonymousSep 16, 2026 00:43
He's on the thin side, but still within a normal weight range, so I don't see the problem.
45AnonymousSep 16, 2026 00:53
He got told he was pre-diabetic and lost weight because of it — if anything that's a good thing, no?
48AnonymousSep 16, 2026 00:56
Normally once you're past 50 your body settles down to about this.
Whether it's the Motoki pattern, some illness or surgical condition, or just eating less as you age.
It's the comedians who stay hugely overweight forever that are the weird ones.

The moment these guys retire from playing, their calorie intake massively overshoots.
58AnonymousSep 16, 2026 01:13
Lose too much weight and you just end up looking like a gaunt, wrinkly old man.
62AnonymousSep 16, 2026 01:19
Diabetes has nothing to do with me, but it really is bad enough for your body to cause weight loss this drastic.
I get why it ends up being the cause of death for so many people.
64AnonymousSep 16, 2026 01:24
Kiyohara's diabetic too, but he's stayed heavy, hasn't he? (Kazuhiro Kiyohara, another former pro baseball star.)
65AnonymousSep 16, 2026 01:24
Why not just say flat-out 'you have diabetes'? Why phrase it as 'basically diabetic'?
67AnonymousSep 16, 2026 01:25
Former 'ramen shop owner'
Did this guy have any other title besides that?

Re: #67
Apparently he used to be some kind of pro athlete
Sepak takraw, maybe? (a joking guess — sepak takraw is a Southeast Asian kick-volleyball sport)

Here you go
Background and Talking Points
The phrase “basically diabetic” appears to describe a “pre-diabetic” stage, where blood sugar or HbA1c levels are close to the diagnostic threshold — wording doctors often use to convey the situation without issuing a formal diagnosis. In recent years, rapid weight loss via GLP-1 receptor agonists (such as Mounjaro) has become a hot topic, and the thread included posts from users sharing their own treatment experiences. On the other hand, specific speculation about Motoki’s diet or personal relationships could not be confirmed in the original article and amounts to baseless conjecture, so it has been excluded here. Rapid weight loss can result from treating lifestyle-related disease, but it can also stem from other underlying conditions, so it’s worth noting that the cause can’t be determined from appearance alone.
