The yo-yo effect is not simply weight regain—it reflects the body increasing its energy storage efficiency. From a TKM perspective, excessive dieting weakens the Spleen (Spleen Deficiency, 脾虛), leading to accumulation of Dampness (濕) and Phlegm (痰), which can obstruct Qi and Blood flow and even cause Blood Stasis (瘀血). In this state, eating less fails to reduce weight; instead, water retention and bloating occur. At our clinic, Baekrokdam Korean Medicine Clinic, we use a phased approach to prevent yo-yo effects. Week 1 focuses on restoring Spleen-Stomach (脾胃) function with herbs that Tonify the Spleen (補脾) and regulating meal timing—patients notice improved digestion and relief from constipation or diarrhea rather than weight changes. Weeks 2–4 emphasize promoting Qi circulation and eliminating Damp-Phlegm (痰飮); the body shifts from 'storage mode' to 'consumption mode,' reducing facial and ankle swelling and prompting gradual weight loss of about 1–2 kg. After 1 month, we reinforce both Spleen and Kidney (脾腎) to raise the metabolic baseline; with consistent lifestyle habits, weight stabilizes without rebound. Rather than fixating on a single diet method, a slow, constitution-based approach is the faster path. Having experienced this myself, I understand the struggle. During a consultation, we can create a step-by-step plan tailored to your current condition.
