Announcer Kasumi Mori Reveals How She Lost 7kg in 3 Months on a ‘Don’t Spike Your Blood Sugar’ Diet

Freelance announcer Kasumi Mori revealed on TBS Radio how she lost 7kg in three months. “There’s just no way I could do a starvation diet,” she said — the method she landed on was one that avoids spiking her blood sugar.

On 5ch, some users explained the mechanics of insulin and fat storage, while others speculated that a drug (Mounjaro) might be the real reason behind the weight loss, and skepticism toward extreme dieting also made the rounds.

Sun, 8/23, 4:14 PM

Freelance announcer Kasumi Mori (31) made a guest appearance on the August 22 broadcast of TBS Radio’s “Savorino presents My Reward Time” (Saturdays, 8:00 PM). She revealed how she lost 7kg in three months.

Making her second straight appearance on the show, Mori was asked by host Miki Fujimoto, “You’ve dieted before, right?” Mori explained what got her started: “Yeah, about a year after going freelance I put out a photo book, and around that time I did a body makeover. Then when I became an ambassador and model for a lingerie brand, I needed to slim down a bit more, and that’s when I lost about 7kg.”

Honestly, just not eating is the easiest way to lose weight.

That's pointless — you rebound too easily on that.

Blood sugar?
So basically… she's on Mounjaro?

Ah, that stuff exists now so of course it's easy.

You should just treat white rice as poison. Freshly cooked white rice especially. Can't say that on TV though.

Even a small amount of white rice or mochi (rice cake) spikes it shockingly fast.
Probably better for your body not to eat them at all.

Funny coincidence, I got flagged at my health checkup back in May too — I've gone from 71kg to 63kg since then.

The low-insulin diet, huh.
It had a moment a while back, but there were a lot of mishaps so I'd guess fewer people do it now.

Isn't insulin the hormone that lowers blood sugar?
31Anonymous2026/08/23(日) 16:56:21.46ID:onkTD4aJ0
"Lowers your blood sugar? As if some coffee could do that…"
like that one commercial.

Once you hit your mid-50s your metabolism tanks so hard that dieting barely does anything and the weight just won't come off.
My doctor keeps telling me to lose weight, but once I switched my goal to just maintaining, I felt a lot more at ease.
33Anonymous2026/08/23(日) 16:57:16.30ID:U30QXXQC0
She lost 7kg — so what was her starting weight?
35Anonymous2026/08/23(日) 17:01:18.94ID:aGFE2smX0
Cutting out snacks made me lose weight instantly, but that only worked up until my 40s…
37Anonymous2026/08/23(日) 17:03:45.60ID:os20vapZ0
Nah, if you walk 20km every single day you'll lose 5kg.

Depends on the person. If you're used to mountain climbing or hiking, you walk more efficiently, so even carrying a 15kg pack you won't lose that much.
46Anonymous2026/08/23(日) 17:18:22.04ID:p9P8r4430
While you're actually eating you want more, but if you stop at 80% full and wait a bit, you genuinely stop wanting it.
56Anonymous2026/08/23(日) 17:35:44.77ID:7UNArGfT0

80% full or even a bit before that is fine — the key is whether you can hold yourself back even when you still want more.
Once that becomes a habit, you really do start feeling satisfied on small portions. Honestly, I think everyone eats too much these days…
47Anonymous2026/08/23(日) 17:18:50.64ID:AhuNuMK10
Even if Kasumi had a sloppy body, I honestly wouldn't care.
54Anonymous2026/08/23(日) 17:30:49.59ID:XOaKBCEn0
It's Mounjaro, isn't it.
You can get scary skinny on that stuff no problem.

That photo has this weighty, Mona Lisa kind of presence to it.

Does steak even raise your blood sugar?
62Anonymous2026/08/23(日) 17:47:55.22ID:q/PQEZmA0

It doesn't, right?
Guess that's because people eat it together with bread or rice.
89Anonymous2026/08/23(日) 18:43:07.18ID:IV/Q7Hu40
Feel like there was a video yesterday debunking the "veggies first" method… guess I'll watch it later.
95Anonymous2026/08/23(日) 18:55:11.91ID:r7Fi5TXf0

Apparently you don't even need to eat vegetables first.

As long as it's not carbs.
90Anonymous2026/08/23(日) 18:45:01.31ID:qc1UtsBk0

That's why it's about eating in a way that doesn't trigger much insulin release — a diet that keeps sugar as low as possible.

Ah, got it, makes sense.
