Tu cuerpo no es una calculadora: La verdad sobre las calorías y el rendimiento real

Do you train hard but feel stuck or constantly tired? Discover what energy budgeting is and why your body prioritizes survival over performance. Many athletes mistakenly believe that energy is simply a matter of calories burned (CICO). However, human physiology is much more complex. In this video, we explore how your body manages its resources and what happens when your "budget" is insufficient: from RED-S (Relative Energy Deficit in Sport) to hormonal imbalances in testosterone, the menstrual cycle, and thyroid function. Learn to identify the red flags of chronic fatigue and how a comprehensive blood test (ferritin, cortisol, free T3) can be the key to unlocking your true performance. It's not about pushing yourself harder, but about giving your body the budget it needs to repair, adapt, and build. 📖 MY FIRST BOOK: "Hormones, Metabolism, and Performance" https://amzn.to/3QNPjnq ✍️ You help me a lot by leaving a review on Amazon.
