In Korean medicine, weight gain is not seen merely as a calorie issue but as an imbalance of Qi flow and organ function. Common causes include Spleen Deficiency (Spleen Qi Deficiency—impaired water metabolism leading to fluid retention), Phlegm-Dampness (accumulation of unmetabolized fluids), and Blood Stasis (blocked circulation). Treatment typically progresses in three stages. The first 1–2 weeks are an 'adaptation period' where herbs regulate the gut environment and promote Qi and blood circulation. Many patients experience improved digestion, increased bowel movements, abdominal comfort, and reduced facial or limb swelling—often feeling lighter before the scale changes. The next 2–4 weeks are the 'adjustment period,' with herbs that tonify the Spleen and Kidney to boost energy metabolism. Appetite stabilizes, intermittent hunger decreases, and weight gradually decreases (1–2 kg per week, though individual variation is significant). More important than scale weight is noticing changes in waistline or how clothes fit. From week 4 onward is the 'stabilization period.' The prescription is fine-tuned according to constitution; weight loss slows but sustained changes occur. Typically after 2–3 months, basal metabolic rate increases, and you find that eating the same amount no longer leads to weight gain as before. However, the effect lasts longer when combined with dietary patterns and light movement. I also learned from some trial and error that the saying 'when the body responds first, the mind follows' is really true.
