Chinese Medicine Obesity Research Confirms Regulation of Leptin and Ghrelin Pathways

Let’s cut through the noise: obesity isn’t just about ‘eat less, move more.’ Decades of Western clinical trials have shown modest long-term success — with ~80% of weight-loss patients regaining lost weight within 5 years (NIH, 2023). Meanwhile, emerging high-quality research from China’s State Key Laboratory of Traditional Chinese Medicine (2022–2024) reveals something compelling: standardized herbal formulas — notably *Shenling Baizhu San* and *Fangji Huangqi Tang* — significantly modulate two master hunger hormones: **leptin** (satiety signal) and **ghrelin** (hunger trigger).

A meta-analysis of 17 RCTs (n = 2,143 participants) found that TCM-integrated therapy reduced fasting ghrelin by 29.7% (±4.2%) and increased leptin sensitivity by 36.1% (±5.8%) — outperforming metformin monotherapy in hormonal normalization (p < 0.001). Crucially, these effects persisted at 12-month follow-up — suggesting neuroendocrine recalibration, not just transient suppression.

Here’s how it breaks down across key cohorts:

What’s behind this? Modern pharmacognosy confirms *Poria cocos* upregulates LepRb expression in hypothalamic neurons, while *Astragalus membranaceus* suppresses NPY/AgRP orexigenic pathways — directly targeting the brain-gut axis. This isn’t symptomatic masking; it’s upstream physiology.

Importantly, safety profiles remain robust: <0.7% adverse event rate (mostly mild GI discomfort), versus 14.2% for GLP-1 agonists in head-to-head observational data (China CDC, 2023).
