📝 Detailed Answer
Many people attempt extreme diets by fasting or restricting themselves to a few specific foods, but this often leads to dizziness and a stubborn weight-loss plateau. There is a biological and holistic reason for this.
Biologically, extreme low-calorie diets trigger the body's survival instinct. When energy intake is too low, the body may lower thyroid hormone levels to slow down the metabolic rate. Consequently, your body transforms into a constitution that resists weight loss even when you eat very little.
From the perspective of Traditional Korean Medicine (TKM), this is viewed as Spleen Deficiency (Bi-heo, 脾虛). The Spleen is the core organ responsible for transforming food into energy. When its function is compromised, nutrients are not absorbed efficiently, leaving behind metabolic residues known as 'Phlegm-Fluid' (Dameum, 痰飮). This accumulation of unnecessary fluids and waste is precisely why your body feels heavy and lethargic.
Furthermore, if stress is added to this state, it can lead to 'Blood Stasis' (Eohyeol, 瘀血), further obstructing circulation and decreasing metabolic efficiency. Rather than focusing on simple calorie counting, the priority should be restarting your body's digestive function and 'metabolic switch.' Sustainable weight management is only possible by increasing your metabolic rate according to your specific physical constitution.
