Eating Three Servings of Kimchi Daily Linked to Lower Risk of Obesity

“This is an observational study, so it doesn’t show that eating kimchi causes a reduction in obesity risk,” Samantha Cassetty, MS, RD, nutrition and wellness expert and co-author of Sugar Shock. “But it suggests a link between the two, which raises the possibility. It’s in line with previous research with similar findings–that kimchi intake is associated with a lower risk of obesity and may help reduce body weight and waist size. That said, the study was limited to Korean participants, so the association between kimchi and protection against obesity might not hold up in other populations.”

Cassetty continued: “If you want to try this, it’s healthy for most people, however, kimchi is high in sodium, and most people are already overdoing. So, find ways to reduce the sodium in your diet by replacing ultra-processed foods with whole foods–especially plant foods, which contain potassium that helps counter the effects of sodium.”

It’s also notable that in this study, just eating more kimchi was not necessarily linked to a smaller waistline.

“The authors note this may be because of how kimchi is often eaten–with rice,” Cassetty stated. “So, higher intakes might come with eating more in general, particularly more ultra-processed foods, which are also linked with higher rates of obesity.”

Since this is an observational study, it’s hard to know the extent of the role kimchi played in weight loss. There are numerous factors to take into consideration including overall diet and lifestyle.

“Kimchi is made from pickled cabbage and cabbage is a healthy cruciferous vegetable that has fiber, Vitamin C and Vitamin K,” said Natalie Rizzo, MS, RD, author of Planted Performance. “Kimchi is made by fermenting cabbage, which means it has ‘good’ bacteria, or probiotics. The authors of this study hypothesize that the bacteria strains in kimchi aid in weight loss, but since it’s an [observational] study, there’s no way to know if the weight loss is from those bacteria strains or something else.”

Furthermore, “kimchi is a low-calorie food, and eating it may help you reduce your calorie intake and lead to weight loss. Since it’s rich in fiber, it may help keep you full without adding many calories to a meal,” Rizzo added.

Fermented foods like kimchi are rich in gut-nourishing bacteria that promote the growth of beneficial organisms in your gut microbiome. This ecosystem plays a part in regulating numerous bodily functions–from mood and weight to cholesterol and blood pressure levels to inflammation and immune functioning, Cassetty explained.

Eating kimchi can help create a healthy balance of gut bacteria, allowing the good bacteria thrive while getting rid of the bad bacteria.

“Because of its role in your gut microbiome, kimchi may promote better gut and heart health,” said Cassetty. “Kimchi is also being studied for its potential role in supporting brain health and preserving memory. Your enteric nervous system is located in the gut, so what’s good for the gut is also good for your brain. It’s all connected.”

Kimchi also has antioxidant properties that contribute to its health benefits.

“Antioxidants help stabilize damaged cells that initiate diseases like cancer and heart disease,” Cassetty noted. “So, upping your antioxidant status can help protect you from developing chronic conditions.”

The probiotic properties of kimchi might also help treat yeast infections.

“We also see that kimchi might help protect against obesity,” said Cassetty. “Besides contributing beneficial bacteria to your gut, kimchi is a low-calorie way to add spice to meals. When your meals are flavorful and enjoyable, and you eat mindfully, it’s easier to eat healthier portion sizes, which can help you manage your weight without feeling deprived.”

However, it’s also important to consider that kimchi is high in sodium, and most people are already overdoing this. So, if you’re thinking about adding kimchi to your diet, cut back on sodium elsewhere by choosing whole foods over heavily processed ones and limiting the use of salt in your kitchen, Cassetty added.

“Many people are unfamiliar with kimchi, but you don’t have to branch out of your comfort zone to try it,” Cassetty stated. “Kimchi is a great way to add a kick to familiar foods like turkey burgers, eggs, whole grain bowls (such as brown rice or quinoa bowls), and roasted veggies. You can also try it as a sandwich condiment.”

Rizzo recommends adding kimchi to any food that needs a little crunch. “Top a stir fry or grain bowl with kimchi. Add it to a sandwich for a spicy crunch. You can even top your eggs with kimchi to add texture and crunchiness,” she said.

Eating up to three servings of kimchi each day is linked to a reduced rate of obesity among men, according to a new study.

This study is observational so it’s difficult to measure kimchi’s direct effect on weight loss. Overall diet and lifestyle also play a role.

There are many health benefits of kimchi such as promoting gut health, lowering inflammation and improving immunity.

To add more kimchi to your diet, it can be used as a tasty topping for many meals.
