Q. Doctor, there are so many diet-friendly foods at Costco these days. From a Traditional Korean Medicine perspective, are there any specific items you would recommend?

It is common to feel motivated at Costco and fill your cart with salads and chicken breasts, though many patients find it difficult to consume them all before they spoil. From a TKM perspective, while bulk items like grass-fed beef and pre-cut vegetables are excellent for consistent protein and fiber intake, one must be cautious of their energetic nature. Many popular diet foods are 'cold' in nature. Over-relying on frozen fruits or raw salads can lead to 'Biheo' (Spleen Qi Deficiency), where the digestive system weakens, often resulting in bloating and edema. In TKM, when food is not properly transformed into energy, it turns into 'Dameum' (Phlegm-fluid), a metabolic waste that can actually make your body more resistant to weight loss. The key is matching food to your constitution: individuals with a 'cold' constitution should prioritize cooked or steamed vegetables, while those with excess 'heat' can benefit more from fresh, raw greens. To achieve a sustainable diet without the yo-yo effect, I recommend first identifying your body’s energy balance before your next shopping trip.
