Q. If I don't exercise at all and only take herbal medicine, will I still lose weight?

To give you a direct answer: taking only herbal medicine can lead to initial weight loss. In particular, when the root cause in Traditional Korean Medicine is spleen deficiency (pi xu) or phlegm and fluid retention (tan yin), herbal formulas can strengthen spleen-stomach function and eliminate excess dampness and phlegm, stabilizing appetite and making the body feel lighter. I have seen many such cases. However, there are downsides. First, relying solely on herbal medicine without exercise may reduce muscle mass and lower basal metabolic rate. Second, the effects of herbal medicine are relatively gradual, so those seeking rapid results may become frustrated. Third, if lifestyle habits remain unchanged, the risk of rebound weight gain after stopping the herbs is high. From my clinical experience, patients who combine exercise with herbal therapy maintain their results much longer. Ultimately, the answer depends on the individual’s situation. If your main goal is constitutional improvement and appetite regulation, herbal medicine alone can be sufficient. But if you aim to reduce body fat and reshape your figure, it is far wiser to incorporate at least light exercise. Herbal medicine cannot fully replace exercise. However, if you feel too heavy to start exercising or lack motivation, a good approach is to first build up your strength with herbal medicine and then add exercise later.
