🔥 Understanding TDEE
TDEE (Total Daily Energy Expenditure) is the total number of calories you burn each day, including your Basal Metabolic Rate (BMR) and activity level. Knowing your TDEE helps you set accurate calorie targets for your fitness goals.
📊 How It Works
We use the Mifflin-St Jeor equation, the most accurate formula for calculating BMR. Your BMR is then multiplied by your activity level to get your TDEE. From there, we adjust calories based on your goal (deficit for weight loss, surplus for weight gain).
💡 Pro Tips
- Start conservative: It's easier to lower calories than to increase them
- Track consistently: Monitor your weight weekly and adjust as needed
- Focus on protein: Aim for 0.7-1g per pound of body weight
- Be patient: Sustainable changes take time, typically 1-2 lbs per week
