Q. I heard swimming is great for weight loss and I'm thinking of starting. As a TKM doctor, do you really recommend swimming for dieting? Or is there a more effective method?

Swimming has many benefits, particularly its buoyancy which protects the knees and back of overweight individuals while boosting the basal metabolic rate. However, it has specific drawbacks for weight loss. When the body loses heat in cold water, it naturally increases appetite and tends to accumulate subcutaneous fat to maintain core temperature. From a Traditional Korean Medicine (TKM) perspective, individuals with Spleen Deficiency (脾虛, weak digestive function) or Qi Deficiency (氣虛, lack of vital energy) may experience stagnant circulation due to the cold, leading to the accumulation of 'Phlegm-Fluid' (痰飮, pathological metabolic waste), which often results in edema and weight gain. Conversely, for those with internal heat or 'Blood Stasis' (瘀血, stagnant blood), swimming is an effective way to cool the body and promote circulation. Rather than deciding if swimming is objectively good or bad, you must determine if your body is compatible with cold water. If swimming leaves you excessively hungry or causes your body to swell, brisk walking in the sun may be more effective for fat burning. I recommend a constitutional consultation to find the exercise that best suits your metabolic type.
