Q. I've heard that the perilla oil diet is trendy lately. How exactly does consuming oil help with weight loss?

From a biomedical perspective, the key lies in Alpha-Linolenic Acid (ALA), which accounts for over 60% of perilla oil's composition. Modern diets, especially for those who eat out frequently, are often excessively high in Omega-6 fatty acids, which can trigger chronic inflammation and impair insulin function. Consuming the Omega-3s found in perilla oil helps activate fat-burning genes and suppress inflammation, essentially laying the groundwork for a 'fat-burning metabolism.' In Traditional Korean Medicine (TKM), this mechanism is explained as the cleansing of 'Dameum' (phlegm-fluid) and 'Eo-hyeol' (blood stasis). When 'Dameum'—a form of sticky metabolic waste—accumulates, it obstructs the circulation of Qi and blood, making the body constitutionally prone to weight gain. Perilla oil possesses a 'warm nature' that facilitates smooth communication between the internal organs. It is particularly effective for individuals with 'Piheo' (Spleen Deficiency) who suffer from a sluggish metabolism. The high-quality oil lubricates the intestines and helps discharge toxins, effectively flipping the body's metabolic switch. It is important to remember that perilla oil is still a fat and contains significant calories. Rather than simply increasing your total intake, the goal should be to replace 'bad' fats in your current diet with perilla oil. Because the optimal amount can vary depending on your specific constitution and metabolic state, I recommend having your physical condition professionally evaluated to determine the best approach for you.
