I once tried eating nothing but boiled cabbage myself, driven by sheer motivation. Within three days, I felt drained and dizzy. Let me share some practical insights I gained from that experience. Cabbage certainly has clear benefits. It is packed with dietary fiber to aid bowel movements, and Vitamin U provides robust protection for the gastric mucosa—truly like medicine for those experiencing heartburn during a diet. However, one must not overlook its 'cold nature.' If you have Spleen Qi Deficiency (脾虛), characterized by cold hands and feet or frequent diarrhea, you must be cautious. Excessive consumption can cause gas, lead to the accumulation of Phlegm-rheum (痰飮), and ultimately slow down your metabolism. For working professionals in their 30s to 50s, maintaining muscle mass is vital. Relying solely on cabbage will quickly lead to burnout. I recommend using cabbage as a 'reliable supporting character' rather than the protagonist. Be sure to pair it with warm-natured proteins like beef or chicken. In Korean Medicine, we focus on resolving chronic Blood Stasis (瘀血) to improve the circulation of Qi and Blood, creating a body that naturally burns energy efficiently. Please remember that a diet tailored to your specific digestive capacity and constitution is the real key to preventing the yo-yo effect.
