The yo-yo effect isn't a failure of willpower—it's your body's instinctive survival response, which is why it keeps repeating. When you suddenly reduce calories, your body enters 'starvation mode,' lowering energy expenditure and preparing to store calories rapidly when you eat again. Extreme crash diets cause initial weight loss from water and muscle, which actually decreases your basal metabolic rate. This means when you revert even slightly, most weight returns as fat. In TKM, spleen deficiency (비허) is viewed as a primary cause—when spleen function weakens, energy transformation and metabolism slow, and dampness accumulates, leading to edema and weight gain. When combined with blood stasis (어혈), circulation worsens, causing cold extremities while heat accumulates centrally, creating an upper heat-lower cold (상열하허) pattern. Rather than simply saying 'don't eat,' the approach first considers: whether you've done extreme diets recently (requiring metabolic reset time), if you had a concrete maintenance plan, whether emotional eating patterns exist, and if circulation issues (cold hands/feet with flushed face) are present. Body shaping requires more focus on maintenance than initial weight loss. Our clinic analyzes obesity causes through constitution, lifestyle habits, and emotional patterns to provide personalized management. For those with repeated diet failures, understanding why the cycle continues is the essential first step.
