Q. I heard tomatoes are great for dieting. How exactly do they help with weight loss?

Many people stock up on tomatoes when starting a diet, but they are most effective when you understand their underlying principles. From a Western medical perspective, the fiber in tomatoes promotes beneficial gut bacteria and prevents blood sugar spikes. This stabilizes insulin levels, shifting the body's metabolism from storing fat to burning it. Additionally, the antioxidant lycopene is highly effective at discharging triglycerides from the body. In Traditional Korean Medicine (TKM), we prioritize addressing 'Stomach Heat' (Wi-yeol) when examining obesity. Excessive heat in the stomach can cause an abnormally high digestive drive known as 'Sik-da-seon-gi' (polyphagia), a condition where one feels persistent hunger even after eating. Tomatoes, which have a cooling nature, help extinguish this internal heat and replenish 'Body Fluids' (Jin-yeok), effectively calming an overactive appetite. For individuals who struggle to lose weight despite their efforts, metabolic waste such as 'Phlegm-fluid' (Dam-eum) or 'Blood Stasis' (Eo-hyeol) often hinders progress. The high water content and organic acids in tomatoes are excellent for reducing edema caused by 'Spleen Deficiency' (Bi-heo). However, if you have a 'Cold' constitution, consuming too many raw tomatoes may cause indigestion. In such cases, I recommend lightly cooking them; this not only aids digestion but also increases the absorption rate of lycopene by four to five times.
