Many people experience extreme fatigue or dizziness after a binge following a strict fast; this happens because the body is highly vulnerable to sudden overeating. In Traditional Korean Medicine, we prioritize assessing the state of 'Bi-heo' (脾虛), which refers to a deficiency in the Spleen function resulting in weakened digestion. If you consume greasy or heavy foods while in this state, it can lead to the formation of 'Dam-eum' (痰飮)—the accumulation of metabolic waste and phlegm—which makes the body feel heavy and sluggish. Therefore, I recommend the following structured approach: 1. Preparation: Drink more water the day before to ensure a smooth metabolic flow. 2. Prioritize Protein and Vegetables: Start your meal with salads or proteins to prevent a blood sugar spike. 3. Moderate Your Favorites: Choose the foods you crave most, but limit the portion to about 80% of your usual amount. 4. Finish with Warm Tea: Drink ginger or plum tea after the meal to prevent the stagnation of 'Eo-hyeol' (瘀血, blood stasis) and waste products. 5. Light Walking: Walk for about 20 minutes after eating to promote the circulation of Qi and Blood. The true purpose of a cheating day is to satisfy psychological hunger and break through weight-loss plateaus. A smart cheating day tailored to your digestive capacity is the key to a sustainable diet.
