📝 Detailed Answer
Biologically, sugar substitutes provide a sweet taste without being absorbed into the bloodstream like actual sugar. This results in lower insulin levels—the hormone responsible for fat storage—making them helpful for short-term weight management.
However, Traditional Korean Medicine offers a different perspective. Constant intake of artificial ingredients can lead to 'Bi-heo' (脾虛), or Spleen Deficiency. In TKM, the Spleen is the central organ responsible for transforming food into energy. When its function is impaired, energy levels drop and the basal metabolic rate slows down. Furthermore, the body can be deceived by this 'fake sweetness,' potentially triggering a vicious cycle of cravings for actual sugar.
Additionally, this process can lead to the formation of 'Dam-eum' (痰飮), which are pathological fluid accumulations or metabolic waste. When Dam-eum builds up due to impaired fluid metabolism, it often manifests as a feeling of heaviness, bloating, or edema. Rather than simply switching your beverage, it is far more important to 'reset' your body's metabolic switch.
