📝 Detailed Answer
It is impressive that you are putting so much effort into healthy foods like tofu and cabbage. From a Traditional Korean Medicine (TKM) perspective, such diets have both pros and cons. The advantages include low calories and high fiber, which improve bowel movements and reduce edema by eliminating excess sugars.
However, long-term adherence can be problematic. A deficiency in proteins and essential fats can lead to 'Bi-heo' (Spleen Deficiency), where the digestive system's energy is depleted. When the body lacks vitality, it instinctively tries to conserve energy, creating an environment prone to the 'yo-yo effect.' Furthermore, if your body harbors 'Dam-eum' (phlegm-fluid retention) or 'Eo-hyeol' (blood stasis), you may hit a weight-loss plateau regardless of how little you eat.
The key lies in your current physiological state. Instead of blindly restricting intake, it is far more efficient to boost your metabolism using herbal medicine so that your body naturally consumes energy. By complementing your current diet with a prescription tailored to your specific constitution, you can manage your weight much more comfortably and sustainably.
