📝 Detailed Answer
The primary reason the cabbage diet seems effective is simply the severe reduction in calories; when energy intake drops suddenly, the body utilizes stored fat, causing rapid initial weight loss. However, from a Traditional Korean Medicine (TKM) perspective, this approach can easily lead to 'Bi-heo' (Spleen Deficiency). When the function of the Spleen—responsible for digestion and absorption—weakens, your overall energy levels drop, leading to chronic fatigue. For those with naturally weak digestive systems, consuming excessive cabbage can actually cause bloating and abdominal gas.
Furthermore, for individuals suffering from 'Dam-eum' (phlegm-fluid retention) or 'Eo-hyeol' (blood stasis), which obstruct the circulation of Qi and Blood, adopting an extreme starvation-style diet can further impair the body's natural detoxifying and self-healing abilities.
In clinical practice, I always emphasize that *how* you eat according to your body's capacity is far more important than *what* you avoid. The real key to sustainable weight loss without the 'yo-yo' effect is finding a nutritional balance that suits your specific constitution (Sasang typology). Before starting such a regimen, it is crucial to assess your current digestive health and overall energy levels.
