I understand the frustration of extreme fasting; the dizziness from hunger often leads to binge eating and a sense of defeat. To prevent the yo-yo effect, it is essential to reset your body's 'default setting.' At Baekrokdam Korean Medicine Clinic, we take a phased approach: 1. Constitution Analysis and Metabolic Assessment: We first examine whether your body is utilizing energy efficiently. We identify if you are in a state of 'Bi-heo' (Spleen Deficiency), where digestive functions are impaired, or if your 'Qi' (vital energy) is stagnated. 2. Removal of Waste and Toxins: We clear 'Dam-eum' (phlegm-fluid/metabolic waste) and 'Eo-hyeol' (blood stasis) accumulated in the body. Clearing these blockages is necessary for a smooth metabolism. 3. Restoration of Basal Metabolic Rate: We elevate metabolic functions that have dropped due to excessive calorie restriction. By restoring the functions of the Spleen and Stomach, we create a body that utilizes energy efficiently even with smaller portions. 4. Establishing a Weight Maintenance System: We provide a stabilization period to gradually lower the 'set point' remembered by the brain after rapid weight loss. During this time, constitution-specific herbal medicine is used to regulate appetite and soothe psychological hunger. Ultimately, the secret to preventing the yo-yo effect is losing weight at a pace your body can handle while compensating for constitutional weaknesses. Rather than struggling through trial and error alone, I recommend starting with an accurate understanding of your body's current state.
