Q. I keep gaining back weight after dieting. How can I prevent the yo-yo effect?

In Traditional Korean Medicine, the yo-yo effect often stems from ignoring one's constitution and relying on extreme fasting or drugs, which makes the body perceive a 'state of emergency' and store more fat. This is viewed as spleen deficiency (pi xu)—weak spleen function disrupts fluid metabolism and accumulates phlegm-fluid (tanyin) and blood stasis (yu xue), making weight loss difficult. To prevent rebound, first identify your constitution: for example, Taiyin types have weak liver function and tend to store fat, while Shaoyang types have sensitive digestion and react poorly to severe dietary restrictions. Key steps include: 1) Constitutional diagnosis via pulse and tongue examination to tailor lifestyle habits. 2) Strengthen the spleen with herbs like atractylodes (baizhu) and ginseng to normalize digestion and prevent fat storage. 3) Remove accumulated phlegm-fluid and blood stasis with herbal medicine to improve metabolism and circulation. 4) Engage in constitution-appropriate light activity—moderate aerobic exercise for Taiyin types, gentle stretching for Shaoyang types—rather than intense workouts. Herbal medicine and acupuncture support this process, but consistent lifestyle management is crucial. Avoiding impatience and gradually transforming your constitution is the key to sustainable weight management without yo-yo effect.
