Q. After dieting, I always experience the yo-yo effect. How can I prevent it?

Patients with recurring yo-yo effects typically fall into two patterns. Pattern A: those who lost weight rapidly through fasting or single-food diets. This weakens digestive function, leading to poor nutrient absorption while the body conserves energy—identified as Spleen Deficiency (脾虛), where the spleen's ability to transport nutrients declines. Recovery requires warm, easily digestible foods rather than further restriction. Pattern B: those who lost weight steadily but under strict dieting or stress. This can impair liver function, causing Qi Stagnation (氣滯) and increasing the risk of Blood Stasis (瘀血) or Phlegm-Fluid (痰飮). Treatment focuses on improving circulation and clearing accumulated waste. Ultimately, preventing the yo-yo effect relies not on how you lost weight but on your body's post-diet state. A constitutional diagnosis to determine whether the issue is Spleen Deficiency, Phlegm-Fluid, or Qi Stagnation is essential for a tailored approach.
