Many people experience fatigue and dizziness when blindly following trendy diets because shakes alone cannot fundamentally improve metabolic efficiency. In a TKM clinic, we take a more systemic approach. First, we assess your digestive function to see if you are in a state of 'Spleen Deficiency' (Bi-heo, 脾虛). If your absorption capacity is low, relying solely on shakes can further deplete your energy. Next, we focus on clearing 'Phlegm-fluid' (Dameum, 痰飮) and 'Blood Stasis' (Eohyeol, 瘀血)—metabolic waste products that obstruct circulation. Just as a traffic jam slows down cars, these blockages must be cleared to maximize the efficiency of weight loss. We then prescribe customized herbal medicine to quell 'false hunger' signals in the brain and ensure a smooth metabolic flow. In this framework, shakes are used only as a supplementary tool as you gradually transition back to balanced whole foods. This approach allows you to settle into your body's 'ideal weight' and minimize the risk of the yo-yo effect. True sustainability comes from restoring the body's internal balance rather than simply restricting calories.
