Your Muscles Stopped Listening to Insulin—Here's Why | Building Muscle and Losing Weight After 40
Do you feel like your metabolism hit a wall the moment you turned 40? You are eating the exact same foods you ate in your 20s, but suddenly the scale is moving in the wrong direction. According to Dr. Gundry, this isn't in your head—it is a biological shift involving your muscles, your insulin, and a "Thrifty Gene" we inherited from great apes. In this episode, we uncover why the "health foods" you rely on—specifically protein powders and modern fruit—might be the primary drivers of your midlife weight gain. Dr. Gundry explains why your muscles stop "buying" what insulin is selling as you age, and why rapid-absorbing proteins are turned instantly into fat rather than muscle. Plus, we break down the simple "Sugar Math" equation you need to use on every nutrition label to uncover hidden weight-gain triggers. In this episode, you will learn: The "Muscle Math": Why losing 3% of your muscle mass per year is destroying your calorie-burning engine. The Protein Powder Trap: Why liquid protein hits your mitochondria too fast and stores as fat. The "Thrifty Gene": How a 10-million-year-old mutation turns fruit directly into belly fat. The Label Hack: The exact formula to calculate how many teaspoons of sugar are actually in your food. The Longevity fat: Why you should be consuming a liter of this oil every year.
