TDEE Calculator: Calculate Your Total Daily Energy Expenditure
Total Daily Energy Expenditure (TDEE) is the total number of calories you burn in a given day. It accounts for your Basal Metabolic Rate (BMR) as well as the calories burned through daily activities and exercise. Understanding your TDEE is the single most important metric for weight loss, muscle gain, or maintaining your current physique, especially when combined with intermittent fasting.

Why Your TDEE Matters for Weight Loss
To lose weight safely and sustainably, you need to maintain a calorie deficit. By subtracting 300-500 calories from your calculated TDEE, you can determine your optimal daily calorie goal. However, tracking calories manually can be tedious.

How to Use TDEE with Intermittent Fasting
Intermittent fasting (like the 16:8 or 20:4 method) naturally helps you eat fewer calories by restricting your eating window. However, knowing your TDEE ensures you are getting enough nutrition during your feeding phase without overeating. Focus on high-quality, whole foods and scan barcodes to ensure you aren’t breaking your fast with hidden sugars.
