Herbal extract rich in plant flavonoids curbs weight gain in mice through gut bacteria

Medicinal Plants
The flavonoids that give many medicinal herbs and colorful garden plants their pigments and bitterness may work partly by feeding the gut bacteria that help your body burn fat.
Researchers gave mice a plant extract packed with flavonoids while feeding them a fatty diet. The mice ate the same amount but gained less weight and handled blood sugar better. The extract boosted friendly gut bacteria, and those bacteria made a compound that helped turn fat-storing tissue into fat-burning tissue. This was tested in mice only, so human benefits are unproven.
Key Findings
Daily oral extract significantly reduced high-fat-diet weight gain (P < 0.05) and fat accumulation without changing food intake or causing liver injury
Treated mice showed higher oxygen consumption, carbon dioxide production, and heat output (P < 0.01), indicating increased whole-body energy expenditure
The extract increased Lactobacillus, Akkermansia, and Bifidobacterium, raising propionate levels that promoted browning of inguinal white fat and thermogenic gene activity
chevron_right Technical Summary
A flavonoid-rich herbal extract kept mice on a high-fat diet from gaining as much weight and improved their blood sugar control, without changing how much they ate. The extract fed helpful gut bacteria, which produced a fatty acid that switched on fat-burning in the animals' body fat.

A flavonoid-rich medicinal herb extract ameliorates high-fat diet-induced obesity and insulin resistance in mice.
Obesity has emerged as a critical global health challenge, contributing to severe metabolic and neoplastic complications. However, most existing anti-obesity drugs exhibit significant adverse effec...

The plant microbiome consists of the microbial communities—bacteria, fungi, and archaea—that live within plant tissues and in the rhizosphere soil environment, functionally analogous to animal gut microbiota. These microbial communities are crucial to plant science because they directly enhance
