Q. I've noticed perilla oil diets are trending lately; how exactly does it work to help with weight loss?

Many of us question whether trendy diets actually work, but the essence of the perilla oil diet is about changing the 'lubrication' of our body. From a modern medical perspective, alpha-linolenic acid (Omega-3) found in perilla oil reduces cellular membrane inflammation. When inflammation subsides, insulin functions more effectively and glucose metabolism improves, creating a physiological state conducive to weight management. In Traditional Korean Medicine (TKM), this process is similar to managing 'Dameum' (痰飮, phlegm-fluid retention). Dameum refers to the accumulation of metabolic waste and stagnant fluids in the body; resolving this stagnation is essential for restoring a body that loses weight efficiently. For those with 'Bi-heo' (脾虛, Spleen deficiency) or weakened digestive functions, incorporating healthy fats to boost vital energy is often more effective than extreme fasting. However, caution is required. Even healthy fats can lead to excessive caloric intake if overconsumed. For individuals with significant 'Eohyeol' (瘀血, blood stasis) who experience a heavy sensation in the body, an overly oily diet may actually be burdensome. The ultimate answer lies in finding the appropriate amount tailored to your specific constitution. I recommend first assessing whether your current metabolic state is prepared to efficiently process and burn these fats.
