1. **Get a constitutional diagnosis.** Constitution is not simply about genetics but involves a comprehensive assessment of digestive function (spleen-stomach), sweat and cold-heat responses, and bowel movements. For example, Soeumin often have a tendency toward spleen deficiency and weak digestion, while Taeeumin tend to have a lower basal metabolic rate. I used to think, 'Is constitution really that important?' But after some trial and error in clinical practice, I found that starting without a diagnosis makes it easy to regain weight. 2. **Adjust your diet and lifestyle according to your constitution.** Soyangin tend to have more heat and may benefit from cold foods, while Taeeumin may do well with a high-protein, low-carb diet. The key is to gradually switch to ingredients that suit your body rather than extreme restrictions. For those with phlegm-fluid retention or blood stasis, we may add detox-supporting foods. 3. **Use herbal medicine and acupuncture to support constitutional improvement.** For spleen deficiency, formulas like Bojungikgi-tang (補中益氣湯) can enhance digestive function; for excessive phlegm-fluid, Ijin-tang (二陳湯) is prescribed based on pattern differentiation. Acupuncture helps balance the flow of meridians to correct constitutional imbalances. However, I cannot guarantee the same effect for everyone. 4. **Conduct regular reassessments to keep the direction on track.** Constitution is not fixed; it changes with lifestyle and age. I recommend consultations every one to two months to adjust the diet or treatment plan. I explain to patients that it's not about being perfect but about a process of discovering together. Rather than forcing or frightening them, I think it's important to observe the body's changing signals together.
