On a ketogenic diet, CGM traces usually show a lower, flatter 24‑hour glucose curve, while a rare high‑carb meal can cause a higher peak and slower return to baseline because fat adaptation temporarily downshifts rapid glucose disposal (“reverse metabolic inflexibility”) rather than proving true insulin resistance. Learn how to interpret trends despite interstitial‑fluid lag and ...

Between ages 30 and 70, mitochondrial function in skeletal muscle can drop by 25–30%, lowering ATP production and slowing repair, fat metabolism, and hormone output—changes many researchers consider a core driver of aging. The good news is that mitochondria can respond to the right signals, and this guide shows how to recognize dysfunction and rebuild ...

Caffeine-free energy drinks can boost focus without a “crash” by supporting real cellular energy—ATP production in the mitochondria (Krebs cycle) and oxygen/nutrient delivery—rather than blocking brain adenosine receptors, which masks fatigue while adenosine continues to accumulate. Here’s how ingredients like B-vitamins, amino acids, and electrolytes aim to power performance without triggering the cortisol-and-adrenaline stress spike. ...
