It is truly remarkable how medical science has evolved. In the past, weight loss often relied on extreme fasting or stimulants that suppressed sleep; now, the mainstream approach is to regulate hormones to 'trick' the brain. However, this artificial regulation is not the optimal solution for everyone. In Traditional Korean Medicine (TKM), rather than simply focusing on 'eating less,' we concentrate on 'why energy is accumulating.' For instance, if there is an accumulation of Phlegm-Fluid (Dameum, 痰飮)—metabolic waste products—or Blood Stasis (Eohyeol, 瘀血) hindering circulation, metabolic efficiency drops significantly. In such cases, you may feel heavy and struggle to lose weight even while eating less than others. Particularly for those with a Spleen Deficiency (Biheo, 脾虛) type, where digestive function is inherently weak, these potent medications can overly slow gastrointestinal motility, exacerbating side effects like dizziness or nausea. Having experienced the distress of severe indigestion while focusing solely on appetite suppression, I deeply empathize with this struggle. Ultimately, the priority should be restoring your body's innate metabolic capacity. Rather than indiscriminate suppression, the healthiest path to avoid the 'yo-yo effect' is to clear stagnant Qi and Blood circulation and reinforce deficient organ functions to create a body that can 'burn energy on its own.' I suggest we examine your current physical constitution together to find the best approach.
