Abstract Functional foods, such as fermented bamboo shoots, have a long history of consumption among the ethnic communities in northeast India. These locally fermented bamboo shoots contain a wealth of beneficial microbes and metabolites that can help combat metabolic syndromes like obesity. However, the precise effects and mechanism behind fermented bamboo shoot products and their anti‐obesity properties remain unknown. This study aims to explore the different types of fermented bamboo shoot products to determine their potential anti‐obesity effects as well as to analyze their microbial diversity and metabolite profiles. Using both culture‐dependent and culture‐independent methods, we found a high abundance of lactic acid bacteria from the Firmicutes and Proteobacteria phyla in the sample. Gas chromatography–mass spectrometry (GC–MS) based untargeted metabolite profiling detected several aroma‐active compounds, bioactive metabolites, short‐chain fatty acids, and essential amino acids in the samples. The water extract derived from a particular type of fermented bamboo shoot, Melye‐amiley, was found to significantly reduce intracellular lipid accumulation in cultured 3T3‐L1 cells. In addition, this extract increased the expression of lipolytic (hormone‐sensitive lipase, lipoprotein lipase, and adipose triglyceride lipase) and browning regulator genes (uncoupling protein [UCP1], PRDM16, and PGC1‐alpha). By activating the AMPK signaling pathway, the water extract from Melye‐amiley also upregulated thermogenic protein expression and promoted mitochondrial biogenesis and fatty acid β‐oxidation. These findings suggest that fermented bamboo shoot extract has promising anti‐obesity effects by boosting energy expenditure in white adipocytes. Future research is necessary to identify the active ingredient(s) that may lead to new therapies to treat obesity. |
