I have seen many patients who, like myself in the past, spent a significant amount on popular probiotics and supplements only to find themselves visiting the bathroom more often without actually losing body fat. Supplements are exactly that—'supplementary.' While they are accessible and effective at improving the gut microbiome and relieving diet-induced constipation, they lack the potency to drastically alter your basal metabolic rate. For individuals with constitutionally low metabolism, relying solely on these products can often be a waste of resources. In Traditional Korean Medicine, the root causes of weight gain are often identified as Spleen Deficiency (Biheo, 脾虛) and Phlegm-Fluid (Dameum, 痰飮). Spleen Deficiency is a state where the body's ability to transform and transport nutrients is impaired, leading to the accumulation of metabolic waste known as Phlegm-Fluid. While probiotics may assist in temporary intestinal clearance, they do not strengthen the Spleen or prevent the internal formation of Phlegm-Fluid. Therefore, rather than following market trends, I recommend first evaluating whether your body is effectively burning energy. We must assess your digestive health and whether you suffer from morning edema. If your body constantly feels heavy and swollen, focusing on boosting metabolic function through personalized treatment is far more efficient than taking general supplements. Since the best path depends on your unique constitution, let us consult together to find the most effective solution for your body.
