Q. I've often failed at diets because of the yo-yo effect. Is there a specific way to prevent the yo-yo effect?

Frequent yo-yo dieting often results from the body interpreting rapid weight loss as a crisis, leading to fat storage. In Traditional Korean Medicine, this is linked to spleen deficiency (biheo) and qi deficiency (giheo)—weakened digestive function that turns unused energy into phlegm-fluid (dameum) or dampness, making weight gain easier. To break the cycle, the focus is not on eating less but on restoring organ function according to one’s sasang constitution. Clinically, this involves six steps: 1) Constitutional diagnosis via pulse/tongue examination and questionnaires to determine digestive and metabolic type (e.g., Soeumin with weak digestion needs warm foods like yam and ginseng; Taeeumin benefits from low-fat, high-fiber vegetables). 2) Constitution-specific dietary adjustments. 3) Herbal medicine such as Bojungikgi-tang (補中益氣湯) to tonify spleen qi and enhance satiety and metabolism; concurrent treatment for phlegm or blood stasis if present. 4) Lifestyle corrections including adequate sleep, stress management, and constitution-appropriate exercise (e.g., cardio for Soyangin, strength training for Taeeumin), plus acupuncture or moxibustion to improve meridian circulation. 5) A stabilization period of 3–6 months after weight loss, gradually reducing herbs while solidifying habits—this is a crucial ‘relearning’ phase for the body. 6) Periodic reassessment every 3–6 months as seasonal or life changes may shift constitutional balance. The primary goal is not a specific weight but a sensation of bodily ease; improved spleen function manifests in better complexion and regular bowel movements, with weight loss following naturally. Individual variation is significant, so professional guidance is essential.
