Kimchi, a traditional fermented Korean food. Credit: World Institute of Kimchi (WiKim) Kimchi has been shown to reduce body fat and improve gut health, supporting its potential as a dietary strategy to address global obesity, based on various studies and clinical trials.
Obesity has become a global epidemic, with approximately 16% of the world’s population, or about 890 million people, suffering from this condition. The World Health Organization (WHO) has recognized obesity as a significant health issue, emphasizing its detrimental effects on individuals’ quality of life and overall health.
In response, the World Institute of Kimchi in South Korea has published a series of articles in international journals on the anti-obesity effects of kimchi. These articles, based on research studies on the subject, indicate that regular consumption of kimchi, a traditional Korean fermented food, effectively reduces body fat and may serve as a promising dietary strategy to combat obesity.

New research into the effects of kimchi on obesity has yielded compelling evidence supporting its efficacy. Notably, preclinical experiments in animal models of obesity revealed a substantial 31.8% reduction in body fat among those fed a kimchi diet.[1]
Additionally, an extensive analysis of data collected over 13 years from the Korea Genome and Epidemiology Study (KoGES), a large population-based study, found that appropriate kimchi intake is associated with a 15% reduction in body mass index (BMI) and a 12% decrease in obesity incidence among middle-aged males. This study was published in Food & Function[2] and BMJ Open[3] (a British medical journal published by a subsidiary of the British Medical Association).

Clinical Study Insights Continuing this line of inquiry, a study conducted by a team led by Dr. Sung-Wook Hong from the Kimchi Functionality Research Group at the World Institute of Kimchi, in collaboration with the Pusan National University Hospital, South Korea, focused on the anti-obesity effects of kimchi and its impact on gut microbiomes. This study investigated the changes in anthropometric measurements, blood biomarkers, and gut microbiomes of 55 overweight adults, comprising both males and females, with a BMI ranging from 23 to 30 kg/m2. The participants consumed 3 kimchi capsules per meal (60g of kimchi per day) for 3 months. The kimchi capsules contained kimchi powder produced by freeze-drying cabbage kimchi fermented at 4℃ for 2 weeks. The research team analyzed the changes in the body fat composition of the participants and found that the group that consumed kimchi showed a 2.6% decrease in body fat, but the control group that did not take the kimchi capsules exhibited a 4.7% increase in body fat, showing a statistically significant difference between the two groups.
Further, the analysis of the participants’ microbiomes revealed that kimchi consumption increased the abundance of the beneficial gut bacterium Akkermansia muciniphila and reduced the number of Proteobacteria, which are associated with obesity.
Akkermansia muciniphila is a species of gut bacterium that has been reported to reduce inflammation and improve the markers of metabolic syndrome and obesity through the production of short-chain fatty acids (SCFAs).
Global Impact and Future Research The successful completion of this clinical trial on the body fat-reducing effects of kimchi indicates that a steady consumption of kimchi is effective in alleviating obesity symptoms through the modulation of the gut microbiota.
Dr. Hae-Choon Chang, Director of the World Institute of Kimchi, said, “The results of a preclinical study and a clinical trial have systematically verified the anti-obesity effects of kimchi, and present scientific evidence that would help to make the excellent properties of kimchi widely known, thereby laying the foundation for the growth of kimchi as a health food well recognized around the world.” She also said, “We will continue to devote our time, effort, and resources towards scientific research to reinforce the health-functional properties of kimchi, in improving gastrointestinal health in addition to its immune-enhancing and anti-cancer effects, thus firmly establishing the role of kimchi as a global health food.”
The clinical trial on the anti-obesity effects of kimchi was published in the October 2024 issue of the Journal of Functional Foods.
Meanwhile, in Korea, the country where kimchi originated, November 22 was officially designated as a national commemorative day for kimchi and named Kimchi Day in 2020. Kimchi is the first Korean food to be recognized in this manner for its unique health properties. Since then, Kimchi Festivals have been celebrated on Kimchi Day in the U.S., U.K., Argentina, and Brazil on November 22.

Yes, I remember the scene. It’s one of the first things which came to mind when I read the article.

Yes, I’m sure for many it was the first time they ever heard of Kimchi.
Back when I ate in Oriental (I’m not saying “Asian”!) restaurants, they put a bowl of kimchi on the table when you sat down. I liked it, but never have gone looking for it.
I read your profile. Just to encourage you, there ARE ultra conservatives in your area. My cousin and her family are in Cohoes and are super MAGA. They work in Albany. So, they’re there; you just have to find them.
I have purchased it twice and it immediately went into the trash. The lids blew off each time. Thought it was rotten. Is it supposed to do that??
Heating it would kill off the bio buggies, wouldn’t it?
Should have read a couple posts down to find the answer. Cooking with it kills it.
They eat it straight, but they also cook it into other dishes.
Yummy, yummy, yummy....good for my tummy
You can get the same benefit from naturally fermented sour kraut.
And you don’t get the fish sauce and garlic.
That’s the best part!..................
It can but it has to be refrigerated. I’ve only found one good source. It was a lady from China who worked in Dining but she no longer sells it. The biggest issue is the use of large chunks of cabbage. I have to trim it when I get it.
I would guess...
Homebrew, yes.
Sterilized, no.
Have these people ever heard of the Cabbage Soup Diet? After a couple of bowls, I guarantee it will totally flush out your bowels!
...and the house...................
My ex-wife would have us “go on this Diet” a couple times a year even though she was well aware of the danger!
Sadly, yes. Korean youth have embraced western junk food. Obesity and diabetes are on the rise.
When my wife and I were stationed in Korea, a Kimchi refrigerator was part of every condo we looked at. Pro tip: It was good for storing beer as well.
“ From what I’ve been reading lately, any fermented food is good for gut health.”
How do you tell the difference between fermented and spoiled or rotten?
