Effect of Kimchi Intake on Body Fat in Overweight Subjects: A Randomized, Double-blind, Placebo-Controlled Trial
Source: ClinicalTrials.gov · Last updated 10 Jul 2025
Brief summary (registry, in English)
Kimchi, a traditional Korean food, is prepared through the fermentation of various ingredients. It has been reported that kimchi contains beneficial nutrients from its raw materials, as well as lactic acid bacteria (LAB) and their byproducts produced during fermentation. LAB play an important role in the fermentation process, during which the dominant LAB species emerge and undergo a transition process. Depending on the species and strain of LAB, it has specific functions such as promoting weight loss, reducing inflammation, and lowering cholesterol levels. In this study, the effects of kimchi produced from traditional recipe or kimchi fermented with lactic acid bacteria, which have anti-obesity effects, on body composition changes and metabolic disease index will be investigated in subjects with a BMI of between 23\~30kg / m2.
