Q. How does weight loss work step by step from a Traditional Korean Medicine perspective?

Many people wonder how herbal medicine can aid weight loss. In TKM, weight loss is not about simply eating less and moving more; it's about helping the body regain its metabolic balance naturally. The process is divided into three stages: **Stage 1 (Weeks 1–4): Emptying** – This stage focuses on restoring the function of the spleen-stomach (pi wei). Most individuals with stubborn weight gain have spleen deficiency (pi xu) combined with dampness-phlegm (shi tan). A weak spleen cannot properly digest and absorb food, leading to accumulation of waste and swelling. Herbs in this phase promote digestion and expel turbid qi. After about 2 weeks, bowel movements change, bloating decreases, and many lose 2–3 kg (individual variation applies). **Stage 2 (Weeks 5–8): Regulating** – Once the initial 'emptying' is underway, the focus shifts to clearing phlegm-fluid (tan yin) and blood stasis (yu xue). The herbal formula changes to include herbs that smooth qi flow and promote blood circulation, which helps prevent fat accumulation and increase energy expenditure. During this phase, appetite stabilizes, and patients often notice a subjective feeling of fat breakdown, reduced waist circumference, and less breathlessness during exercise. **Stage 3 (Weeks 9–12): Consolidating** – The final stage strengthens the spleen-stomach and kidney (shen) function to prevent rebound weight gain. After weight loss, the body tends to shift into a low-energy conservation mode; herbs here support basal metabolic capacity. The frequency of herbal intake is reduced, and counseling focuses on embedding diet and exercise routines into daily life. Weight may decrease by an additional 1–2 kg or stabilize, but the key goal is improved body composition: maintaining or increasing muscle mass while reducing body fat percentage. Individual constitution and lifestyle affect the timeline, but the emphasis is on gradual, sustainable change rather than rapid loss. Overly aggressive approaches almost always lead to rebound. Therefore, proceeding step by step, allowing the body time to adapt, is essential.
