Many people mistakenly believe that eating only raw salads is the best way to lose weight, but this often leads to bloating and a drop in energy levels. From a physiological perspective, heating vegetables breaks down the tough cell walls (cellulose), allowing digestive enzymes to work more efficiently. This minimizes gastrointestinal stress and enhances the absorption of fat-soluble vitamins, effectively curing 'false hunger' by providing genuine nourishment. In Traditional Korean Medicine (TKM), this approach is seen as a way to improve 'Spleen Deficiency' (Bi-heo, 脾虛). When the Spleen function is weak, the body cannot tolerate the cold nature and coarse fibers of raw vegetables, which can lead to indigestion. Consuming warm, roasted vegetables raises the temperature of the gastrointestinal tract, thereby improving the circulation of Qi and Blood. Particularly for those with an accumulation of 'Phlegm-Fluid' (Dameum, 痰飮) or 'Blood Stasis' (Eohyeol, 瘀血)—metabolic waste products that often correlate with poor digestion—insisting on a raw food diet can actually slow down metabolism further. The key to healthy weight loss is protecting the stomach and boosting metabolism through warmly prepared vegetables.
