Summary

Are you focusing on the wrong thing when trying to boost your metabolism? I want to show you why building and protecting muscle is the single most important thing you can do for your metabolism after 40. In this episode, I explain how muscle serves as your "metabolic spanx" and a "sugar sponge," ensuring carbohydrates are used for fuel rather than stored as belly fat. We will dive into how you can shift away from the "eat less, cardio more" trap and instead use consistent resistance training to turn your body into a fat-burning, health-promoting machine. What you’ll learn: (00:00) Why boosting metabolism isn’t the real solution and muscle is the priority. (02:46) How muscle acts as a metabolic booster, sugar sponge, and hormone messenger. (04:21) What happens to your body when muscle declines with age and menopause. (05:45) Why eating less and doing more cardio can worsen metabolic health. (07:17) How JJ’s personal journey shaped her philosophy on strength training. (09:52) How quickly muscle loss and insulin resistance can occur without activity. (14:14) Why just two strength sessions per week can transform your body. (18:50) How strength training preserves independence, energy, and long-term health. Love the podcast?
