Q. I've heard that weight loss methods vary by constitution. How is a Sasang Constitution diet different from a conventional diet?
Unlike conventional diets that focus solely on calorie restriction, Sasang Constitution dieting analyzes your unique physical traits and the relative strengths and weaknesses of your internal organs to provide a personalized prescription that supplements deficient functions.
📝 Detailed Answer
Most people think of dieting simply as 'eating less and moving more.' However, blindly fasting often leads to a loss of vitality and can even cause the body to swell. Therefore, Traditional Korean Medicine focuses on the Sasang Constitution (四象體質), which refers to the innate strength and weakness of one's internal organs.
Energy metabolism efficiency varies from person to person. Some individuals have a strong digestive system but weak excretory function, while others are the opposite. Applying the same standardized diet to everyone can cause the body to react negatively.
- Taeeumin (Greater Yin Type): These individuals have a strong absorptive capacity and are prone to weight gain and the accumulation of metabolic waste, known as Damjeok (痰積).
- Soyangin (Lesser Yang Type): Characterized by excessive internal heat, they often struggle with appetite control and are prone to lower-body edema due to heat rising to the upper body.
- Soeumin (Lesser Yin Type): Frequently experience Bi-heo (脾虛), or spleen deficiency, meaning their digestive function is weak. Excessive fasting can further lower their metabolic rate.
- Taeyangin (Greater Yang Type): Their energy tends to surge upward, making it crucial to establish stability and grounding in the lower body.
💡 Treatment Goal
The goal is not simply to reduce weight, but to supplement the weaknesses of each constitution, normalize the basal metabolic rate, and create a bodily state that is less prone to the yo-yo effect.
