Q. I've heard that roasted vegetables are recommended for weight loss. What exactly is this, and why does it help with losing weight?

A.

Roasted vegetables are prepared by grilling or roasting in an oven or pan rather than eating them raw or steamed. Heat processing reduces the volume of vegetables and softens the dietary fiber, allowing for higher intake and better nutrient absorption. From a Traditional Korean Medicine perspective, this protects 'Spleen and Stomach (Pi-Wei)' function, reducing digestive strain and activating metabolism to help the body process nutrients more efficiently.

📝 Detailed Answer

Many people insist on eating only raw salads during a diet, but this often leads to a 'cold' interior, resulting in chills and low energy. From a Western nutritional perspective, roasting vegetables removes excess water, increasing nutrient density and making it easier to consume a larger volume of vegetables without the bloating or gas often caused by raw fiber. In Traditional Korean Medicine (TKM), this approach is explained through the concept of 'Warm Yang (On-Yang).' For patients with 'Spleen Deficiency (Bi-Heo),' where digestive function is weakened, the cold nature of raw vegetables can be detrimental. When the stomach becomes too cold, metabolism slows down, leading to the accumulation of 'Phlegm-Fluid (Dam-Eum),' which are abnormal fluid stagnations in the body. Consuming roasted, warm vegetables revitalizes gastrointestinal motility. This creates the ideal internal environment to flush out 'Blood Stasis (Eo-Hyeol)' and 'Phlegm-Fluid,' which are the metabolic wastes that hinder weight loss. I believe that 'how' you eat is just as important as 'what' you eat. To sustain a diet without burnout, you must provide nutrition in a form your digestive capacity can handle. If you are curious about which vegetables and cooking methods best suit your current digestive state, please visit the clinic for a personalized consultation.
