First, for a one-month diet, it is important to set a direction that suits your constitution rather than pursuing drastic changes. I once tried only fasting or exercise, but after some trial and error, I realized that without knowing my constitution, yo-yo effects occur. 1. Constitutional diagnosis – A Korean medicine clinic uses pulse diagnosis and tongue diagnosis to identify your sasang constitution (e.g., Taeumin, Soyangin). Since metabolism and digestive ability differ by constitution, the same diet can have different effects. For those with spleen qi deficiency (biheo), the digestive function is weak, so it is better to start with easily digestible teas (e.g., ginger tea) rather than excessive protein intake. 2. Diet correction – Since one month is a short period, focus on 'meal timing' and 'food properties' rather than extreme low-calorie intake. Cold drinks, flour, and oily foods can create phlegm-fluid retention (dameum), increasing internal dampness (seup) and causing bloating. I recommend switching to warm-natured foods (e.g., yam, chicken breast, vegetables). 3. Exercise and sleep – Moderate walking or stretching for 30 minutes daily is more effective than high-intensity exercise. Sleeping before midnight supports liver function and fat metabolism. For those with blood stasis (eohyeol), light whole-body exercises that promote blood circulation are essential. 4. Herbal medicine – Taking constitution-specific herbal formulas (e.g., Yigibohye-tang for Taeumin, Bojungikgi-tang for Soeumin) can lead to noticeable changes within a month. Although individual results vary, you will feel improved overall condition, not just weight loss. It is safe to receive a prescription after consultation at a Korean medicine clinic. In summary, treat this one month not as a time for miracles but as a period to understand your body and constitution and take the first step. Instead of following dizzying diet tips, consult a Korean medicine doctor for a reliable approach.
