Q. Should I exercise while on a herbal medicine diet, or can I lose weight with just the herbal medicine?

Yes, many patients have similar concerns. I myself, as an early-career Korean medicine doctor, wondered, 'Can herbal medicine really be enough alone?' To give a conclusion first, weight loss is certainly possible with herbal medicine alone. However, combining exercise makes the results more stable. In Traditional Korean Medicine, the causes of obesity are seen as Spleen Deficiency (脾虛, biheo), Phlegm-Fluid (痰飮, dameum), and Blood Stasis (瘀血, eohyeol). Spleen Deficiency refers to weak spleen function leading to poor water metabolism, while Phlegm-Fluid is an accumulation of metabolic waste. Herbal medicine excels at treating these root causes to fundamentally change your constitution. So even with just herbal medicine, you can experience weight loss and a lighter feeling. On the other hand, adding exercise brings clearer benefits: it promotes Gi and Blood circulation, enhances herbal absorption, resolves Blood Stasis, and helps maintain muscle mass. Particularly to prevent rebound weight gain, raising basal metabolic rate is important, and without exercise, herbal medicine alone may lead to muscle loss, which is a disadvantage. Relying solely on herbal medicine can also result in slower weight loss or plateaus. Conversely, if you only exercise without addressing constitutional imbalances through herbal medicine, you may regain weight easily. Ultimately, the approach depends on your situation. If you are a busy office worker with limited time, focus mainly on herbal medicine and try to incorporate at least light walking. If you have more time, combining aerobic and strength training is ideal. The key is consistency without overexertion.
