It is true that commercial diet products are convenient and efficient. However, because they contain standardized ingredients, some individuals may experience side effects such as heart palpitations or insomnia. Through my own clinical experience and studies, I have found that the ultimate solution lies in 'personalization.' In Traditional Korean Medicine, weight gain is not viewed solely as a calorie issue; we examine internal waste and diminished organ function. For instance, if you have Blood Stasis (Eo-hyeol, 瘀血)—where blood circulation is blocked—or Phlegm-Fluid (Dam-eum, 痰飮)—where metabolic waste accumulates—your body may become a constitution that resists weight loss regardless of fasting. Furthermore, for those with a Spleen Deficiency (Bi-heo, 脾虛) constitution and weak digestive systems, restrictive dieting can actually be harmful. Here is a comparison of the two approaches: | Category | Diet Supplements/Products | TKM Customized Diet | | :--- | :--- | :--- | | Approach | Metabolism boost via universal ingredients | Diagnosis of individual constitution and cause | | Primary Goal | Assistance in weight reduction | Improving body environment and restoring balance | | Considerations | General effects of ingredients | Removing individual blockages (Blood Stasis, Phlegm) | | Diet Management | Standardized meal guides | Diets considering digestive function (e.g., Spleen Deficiency) | | Sustainability | High dependence on products | Strengthening self-recovery through constitutional improvement | Rather than stating one is definitively better, it is more important to first understand your current bodily state. I encourage you to identify where the blockages in your system are before deciding on a method.
