Q. What is the 'yo-yo effect,' and how does it differ from general dieting? Which approach is better?

The 'yo-yo effect' refers to the phenomenon where weight regained after a diet exceeds the initial weight. General dieting typically focuses on extreme calorie deficits or intensive cardio. While this produces rapid initial results, the body eventually enters a 'starvation mode,' leading to muscle loss and a drop in basal metabolic rate. Once normal eating resumes, the body stores fat more aggressively, triggering the yo-yo effect. Traditional Korean Medicine (TKM) addresses this by analyzing one's constitution and digestive function. For instance, 'Spleen Deficiency' (Bi-Heo) refers to a weakened digestive capacity where food is not efficiently converted into energy, leading to the accumulation of fluid and waste (phlegm/dam-eum) that manifests as weight gain. Rather than focusing solely on the number on the scale, TKM aims to strengthen a weak constitution and clear metabolic obstructions like Phlegm (Dam-eum) and Blood Stasis (Eo-hyeol). Of course, TKM is not a magic cure. Some patients may experience mild side effects such as indigestion or insomnia with herbal medicine, and the cost can be higher than self-directed dieting. General dieting offers the advantage of complete autonomy and low cost. However, if you have experienced repeated yo-yo cycles—especially if accompanied by chronic fatigue, digestive discomfort, or alternating constipation and diarrhea—a constitutional TKM approach may be more sustainable. Please refer to the comparison table for a detailed breakdown of these two methods.
