Thinking of a treadmill shows you already have the will to diet. However, many people push themselves too hard—increasing speed or time out of eagerness—and end up with sore knees or breathlessness, giving up within one to two weeks. I experienced that myself initially. In Korean medicine, obesity is not simply a matter of being overweight but is understood as Spleen deficiency (Biheo), where the Spleen's function is weakened, causing fluids and nutrients to accumulate instead of circulating properly. If Phlegm-fluid (Dameum) also develops, you may feel easily fatigued and prone to edema. In such cases, excessive running can further deplete Qi and lead to rebound weight gain. Therefore, treat the first 1–2 weeks as a 'metabolic adaptation period.' Focus on walking 20–30 minutes daily, maintaining a heart rate where you can talk but feel slightly breathless (about 110–130 bpm). From weeks 3–4, add a 3–5° incline and slightly increase speed, mixing intervals (1 minute fast + 2 minutes moderate) for 30–40 minutes to activate fat burning. After about a month, you will feel lighter as Blood stasis (Eohyeol)—i.e., circulation disorders—improves. The key is consistency: exercising every other day works better for long-term adherence than daily sessions. In a Korean medicine clinic, we assess your pulse and tongue diagnosis to confirm the degree of Spleen deficiency and Phlegm-fluid, then may prescribe herbal formulas like Bojungikgi-tang to support your exercise routine. Do not overdo it alone; listen to your body's signals and build your strength gradually.
