If you’re a 40+ guy paying at least casual attention to nutrition science, you know this: as we get older, our bodies naturally burn fewer calories.
Given this reality about “base metabolic rate” (BMR), our choices are: (1) Slowly gain weight; (2) Get more active, to counter-balance the BMR decline; or (3) Reduce calories consumed.
I flirted with the first path in my 30’s but ultimately chose to reject Outcome #1, do everything I can toward Outcome #2, and also accept that a bit of Outcome #3 will be needed over time.
Whatever choice you make (and you are making a choice, man), I want it to be an informed one. So please invest a few minutes to learn about your current calorie burn rate, how it’s changing, and how your activity level affects that trajectory. Preview: getting more active can more than offset BMR decline, for many years!
