I also tried extreme fasting when I was young, and I ended up gaining even more weight. It was really tough and I learned through trial and error that yo-yo dieting is your body's powerful homeostasis trying to return to its original weight. First, check your current condition. First, if you've significantly reduced food intake but still aren't losing weight or feel fatigued, you may have 'Spleen Deficiency (脾虛)'. When spleen function weakens, metabolic capacity decreases. In this case, the priority isn't eating less but improving digestive absorption to boost metabolism. Second, if stress causes binge eating and your body swells easily, you may have accumulated 'Phlegm-Dampness (痰飮)' and 'Blood Stasis (瘀血)'. Accumulated waste and stagnant blood disrupt circulation, making weight control difficult. This requires first clearing out the body's 'residue'. Ultimately, preventing yo-yo dieting comes down to 'reactivating your body's metabolic switch.' It's not just about losing weight but creating an environment where your body can maintain a sustainable, healthy weight. Let us help you identify your current state and create a personalized guide.
