Yes, one month is typically enough to start noticing that your body is gradually changing. At first, I thought, 'What can you really do in a month?' But once I actually tried it, I found that approaching it according to your constitution (體質, chejil) leads to clearer changes than expected. From a Korean medicine perspective, a diet program usually follows this sequence: 1. **Assess constitution and current condition**: We first determine whether you have spleen deficiency (脾虛, biheo), a constitution with excess phlegm-fluid (痰飮, dameum), or poor qi and blood circulation. I examine your pulse, abdominal palpation, facial color, and tongue condition to explain why your body is prone to gaining weight. 2. **Customized herbal prescription**: Based on the diagnosis, we use herbs to strengthen the spleen (脾臟, bijang) for better digestion and metabolism, or to resolve accumulated phlegm-fluid and blood stasis (瘀血, eohyeol). The prescription varies completely according to your constitution — not everyone gets the same formula. 3. **Lifestyle and dietary adjustments**: Rather than strict restrictions like 'avoid this food, eat at this time,' we identify specific issues in your current eating patterns. For example, if you have spleen deficiency, we advise warm tea over cold beverages — practical guidance like that. 4. **Regular feedback and fine-tuning**: You visit the clinic every one to two weeks during the month to check changes. Constitution is not fixed; it shifts with seasons and lifestyle changes. So we may slightly modify the herbal formula or add supplementary treatments like acupuncture or moxibustion as needed. 5. **Maintenance and preventing rebound**: After the first month, when you start to feel 'now I get it,' we focus on preventing yo-yo effect. The key is not rapid weight loss but helping your body find its own balance naturally. If the concept of constitution is unfamiliar, think of it as a framework that explains why some people gain weight easily while others don't, even with the same diet. One month is enough time to experience how your body responds within this framework.
