Many gyms and apps still use BMR to calculate calories, but that method leads to poor results and slow progress. In this episode, Marcus and Andrew explain why BMR is the wrong metric and how TDEE gives a true picture of your daily energy needs. They break down the TDEE formula (BMR + NEAT + EAT + TEF), how body fat affects accuracy, and what to do if your metabolism has adapted from dieting too hard. Learn how to fix it with reverse dieting and how to use TDEE to plan fat loss or muscle gain the right way.
