Q. I've heard that it's okay to eat hamburgers while on a diet, but why are some acceptable and others not?

To start with a modern medical perspective, the real issues with hamburgers aren't usually the patties, but rather 'refined sugars' and 'trans fats.' When white flour buns meet sugar-laden sauces, blood glucose levels spike, triggering an excess of insulin that rapidly stores remaining energy as fat. Over time, this can lead to a constitution prone to bloating and weight gain. In Traditional Korean Medicine (TKM), this phenomenon is viewed as the accumulation of 'Dam-eum' (痰飮), which refers to metabolic waste or pathological fluid accumulation caused by improper fluid metabolism. Greasy and irritating foods impair the function of the Spleen and Stomach (脾胃), creating more of these metabolic wastes. Specifically, if one has 'Spleen Deficiency' (脾虛), frequently consuming such foods leads to Qi stagnation, making the body feel heavy and sluggish. If this is combined with 'Eo-hyeol' (瘀血)—stagnant blood or blood stasis—metabolism slows down even further, meaning you may gain weight more easily than others even when eating the same amount. Ultimately, what matters most is your current physiological state. The recommended diet varies depending on whether your digestive power is weak or if waste has accumulated in your body. The fastest way to see results is to first assess your metabolic capacity and adjust your diet accordingly.
