Stir-fried tofu is a fantastic 'cheat key' for weight management. Rich in plant-based protein, it is ideal for preserving muscle mass during fat loss. In Traditional Korean Medicine (TKM), we actively recommend tofu as a primary protein source for patients suffering from Spleen Deficiency (脾虛, Bi-heo), a state where vital energy is depleted. Its high satiety levels are particularly effective at suppressing the 'false hunger' often experienced by stressed professionals in their 30s to 50s. However, constitutional factors must be considered. Tofu inherently possesses a 'cool' (凉) property. If someone with a cold lower abdomen or weak digestion consumes it excessively, it can lead to abdominal distension. This happens because undigested food transforms into 'Phlegm-rheum' (痰飮, Dam-eum)—pathological waste products that obstruct the body's metabolic flow. To counteract this, I recommend stir-frying tofu with 'warm' ingredients like garlic, scallions, or chili peppers to balance its cool nature. Diversifying your protein sources according to your body type is the secret to a sustainable diet without the yo-yo effect.
