Q. Many people fail in dieting due to the yo-yo effect. How can I prevent it?

The yo-yo effect is not simply a matter of willpower; it is a physiological response that occurs when dieting disrupts the body's homeostasis. In Korean Medicine, obesity is broadly categorized into patterns such as Spleen Deficiency (脾虛), Phlegm (痰飮), Blood Stasis (瘀血), and Qi Stagnation (氣滯). Repeated dieting weakens the Spleen, which is responsible for transforming food into Qi and Blood. When Spleen function declines, metabolism slows down, and water and waste products accumulate easily, leading to weight regain and muscle loss. Therefore, the key to preventing yo-yo is to establish a sustainable metabolic balance without excessive strain. I recommend reviewing this checklist: 1) Is your diet method too restrictive? Fasting or mono-diets worsen Spleen Deficiency. 2) Do you feel bloated or gassy after meals? This may signal Spleen Deficiency-related indigestion. 3) Are your hands and feet cold, or do you tire easily? This often indicates concurrent Qi Deficiency (氣虛). 4) Do you emotionally binge-eat or enjoy late-night snacking? This may involve Qi Stagnation or stress-induced Liver Depression (肝鬱). 5) Is your sleep irregular or non-restorative? Disrupted circadian rhythms affect metabolic hormones. Based on these factors, a Korean Medicine practitioner can identify your pattern and recommend tailored treatments—such as tonifying the Spleen with herbal medicine, moxibustion, or acupuncture for Spleen Deficiency; or resolving Phlegm and regulating Qi for other patterns. Each treatment plan is individualized according to constitution and current state, so an in-person consultation allows for a more precise approach.
