Even when I diet, I keep regaining weight. I'd like to know how to prevent yo-yo effect.
To prevent weight regain, start by identifying your constitution. Digestive and metabolic patterns vary by constitution, so the same diet may have different effects. 1) Establish a diet plan suited to your constitution through diagnosis. 2) Avoid drastic calorie restriction; instead, gradually adjust to prevent Spleen Deficiency (bi xu). 3) Strengthen the Spleen and Stomach (pi wei) with herbal medicine or dietary therapy to support gut function. 4) Maintain a regular daily rhythm to help avoid rebound weight gain.
Worried about yo-yo effect? I understand—I’ve been through it myself. In Traditional Korean Medicine, the key concepts are constitution (chejil) and Spleen Deficiency (bi xu).
1. **First, understand your constitution.** Each person’s digestive and metabolic processing differs. For example, the So-eum type often has weak digestion; extreme low-calorie diets worsen Spleen Deficiency, increasing rebound risk. A constitution diagnosis helps tailor your eating principles.
2. **Avoid drastic calorie cutting.** When you suddenly eat very little, the body perceives a famine state and lowers basal metabolic rate. In TKM, this is Spleen Deficiency: the spleen fails to absorb nutrients properly and instead stores fat. Gradually reduce calories by only 300–500 kcal per day.
3. **Focus on restoring gut function.** Post-diet issues like indigestion, constipation, and bloating often stem from accumulated Phlegm-fluid (dameum) or Dampness-phlegm (seupdam). Herbal medicine to tonify the Spleen and Stomach (pi wei) and resolve phlegm helps prevent weight regain. I recommend warming foods for the spleen.
4. **Keep a regular daily rhythm.** Irregular sleep and meal times disrupt hormone balance, especially raising cortisol, which promotes abdominal obesity. Consistent sleep/wake times and three regular meals greatly aid preventing yo-yo effect.
5. **Choose constitution-appropriate exercise.** Not all exercises suit everyone. Tae-yang types may be exhausted by intense exercise, while Tae-eum types benefit more from aerobic activity. Exercise within your limits based on constitution and stamina.
A TKM clinic can provide systematic guidance. Personalized prescriptions and lifestyle management—without promising specific weight loss numbers—can help you achieve healthy, sustainable weight control without rebound.
