The yo-yo effect happens because dieting becomes a fight against your body. In Traditional Korean Medicine, when the Spleen-Stomach (Pi Wei) system weakens, water metabolism becomes blocked, generating Phlegm-Dampness (Tan Yin). Constitutionally, Soeumin and Taeumin types are especially vulnerable to extreme calorie restriction. 1) **Rest your stomach first.** Drastic diet changes worsen Spleen Qi Deficiency. Start with warm porridge or soup to reduce digestive strain. I also made the mistake of thinking 'just fasting will work'—it doesn't. 2) **Seek treatments that promote Qi and blood circulation.** Phlegm-Dampness from Spleen Deficiency doesn't easily clear with exercise alone. Acupuncture and herbal formulas like Bojungikgi-tang (補中益氣湯) can support Spleen function and enhance waste elimination. 3) **Find movement suited to your constitution.** Intense cardio isn't for everyone. Soyangin often benefit from light stretching, while Taeumin may respond better to strength training. 4) **Sleep and stress management are key.** Stress creates Liver Qi Stagnation (Gan Qi Yu Jie), disrupting appetite hormones. A 10-minute abdominal breathing practice before bed can make a big difference. Preventing the yo-yo effect isn't about 'not regaining weight'—it's about helping your body regulate itself. Don't aim for perfection at once; slowly learn to listen to your body's signals.
