How do commercial diet supplements and health foods actually work for weight loss? Also, why do the results seem so inconsistent for me?

I have personally tried many trendy diet supplements in the past. Even as a practitioner, I have spent a lot of time researching if they truly work, only to often end up with an upset stomach and a sense of futility. These experiences taught me a great deal about why a one-size-fits-all approach fails. Common products use Garcinia to block carbohydrate-to-fat synthesis or Catechins to generate heat. Western medicine typically focuses on 'blocking' or 'stimulating' specific metabolic pathways. However, the human body is not a machine that follows a rigid, linear script. Traditional Korean Medicine (TKM) identifies why reactions differ for each individual. First, we must examine Bi-heo (Spleen Deficiency). If the Spleen’s function of digesting and transporting energy is weakened, your body cannot convert even the most expensive ingredients into energy. Instead, undigested residue turns into Dam-eum (Phlegm-Fluid, thick internal waste), making the body bloated and heavy. Furthermore, if you have Eo-hyeol (Blood Stasis)—stagnant blood accumulated in the body—your circulatory pathways become clogged. It is like trying to fan a metabolic flame without providing sufficient oxygen. In this state, expensive supplements lose their way before ever reaching their destination. Pouring premium gasoline into a broken engine will not make the car move. The real answer to weight loss lies in identifying exactly where your body's natural flow is blocked.
