I also struggled in my youth eating only chicken breast and sweet potatoes. At first it seemed to work, but eventually I felt lethargic and dizzy. The human body isn't that simple. In Korean medicine, we help through these steps: 1. **Digestive function evaluation**: Those with spleen deficiency (pi xu) cannot digest high-protein diets well, leading to toxin accumulation. So we check digestive strength first. 2. **Removal of waste products**: We first eliminate accumulated phlegm-fluid (dameum) and blood stasis (eohyeol) from the body to restore metabolism. This allows you to burn calories efficiently even with the same intake. 3. **Custom herbal prescription**: We use herbs tailored to your constitution to boost basal metabolic rate. Rather than forced fasting, we help your body naturally utilize energy. 4. **Gradual diet expansion**: We move away from restrictive chicken breast-only diet and find a balanced point your body can handle. This prevents yo-yo dieting and maintains health. The real key is not 'what you eat' but 'how your body accepts it.' Let's work together to find the right path for your body.
