Yo-yo dieting isn't simply a willpower issue—it's a failure of the body's adaptive mechanisms. In TKM, when spleen deficiency (脾虛) occurs—that is, when spleen function weakens—the body cannot properly convert food into Qi and Blood, and instead accumulates these as phlegm-dampness (痰飮). In particular, extreme low-calorie diets further exhaust the spleen, perpetuating the yo-yo cycle. **Step 1: Assess Your Constitution and Current State** At a Korean medicine clinic, a simple pulse diagnosis and tongue inspection can determine your body type (e.g., So-yang type, Tae-eum type) and the extent of spleen deficiency. For example, if you tend to swell easily, feel fatigued, and are sensitive to cold, you may be a Tae-eum with spleen deficiency. **Step 2: Transition to a Constitution-Matched Diet** Avoid skipping meals entirely, and reduce cold beverages, refined flour, and fruit juices. For spleen deficiency, warm porridges and soups are ideal; for So-yang types, incorporating vegetables and seaweed reduces digestive burden. **Step 3: Directly Support Spleen Function with Treatment** Herbal formulas like Bu-pi-tang (補脾湯) or Tae-eum-jo-wi-tang (太陰調胃湯), combined with moxibustion or acupuncture at points such as Bi-su (BL20) and Jok-sam-li (ST36), improve digestive efficiency and relieve constipation and edema. After about one month of consistent treatment, you typically feel less bloated and lighter. **Step 4: Redesign Movement from a Qi-Blood Perspective** Intense exercise from the start actually depletes Qi. Begin with walking or light stretching; as Qi-blood circulation improves, activity levels naturally increase. **Step 5: Habit Formation and Self-Monitoring** Instead of obsessing over the scale, pay attention to bowel movements, post-meal fullness, and the temperature of your hands and feet. 'Less abdominal bloating' and 'less morning swelling' are signs that your spleen is recovering. I, too, once experienced repeated yo-yo through extreme diets before finding stability with this approach. While constitutional improvement takes time, if you want lasting results without rebound, this approach is more reliable.
