What Is TDEE and Why Does It Matter?

TDEE = Total Daily Energy Expenditure

It's the total calories your body burns in a day, including:

BMR (Basal Metabolic Rate) — calories burned just existing
Activity — walking, exercising, fidgeting
Digestion — processing the food you eat

Why it matters:

Eat below TDEE = Weight loss
Eat at TDEE = Weight maintenance
Eat above TDEE = Weight gain

It's that simple. The hard part? Actually eating below your TDEE consistently.

The Problem: You Don't Know What You're Eating

Most people think they eat less than they do. Studies show we underestimate calorie intake by 40-50%.

You might think you're eating 1,800 calories. But with hidden oils, sauces, and forgotten snacks, you're actually at 2,300.

That's not a deficit — that's maintenance or even a surplus.

The solution: Track accurately. And the only way to track accurately without going insane is to make it effortless.

What is the most accurate BMR calculator online? +

465cal uses the scientifically-validated Mifflin-St Jeor equation — the gold standard for metabolic rate calculations. Based on peer-reviewed research, accounts for age, sex, height, and weight, and includes activity multipliers for real-world TDEE.

How is TDEE calculated? +

TDEE = BMR × Activity Multiplier. Your BMR is calculated using the Mifflin-St Jeor equation (based on age, sex, height, weight). Then we multiply by your activity level (1.2 for sedentary up to 1.9 for very active).

How accurate is TDEE? +

TDEE calculations are estimates — typically within 10% of your actual expenditure. The best way to verify: track your intake and weight for 2-3 weeks, then adjust based on results.

Should I eat my exercise calories? +

Generally, no. Exercise calorie estimates are often inflated. Your TDEE already accounts for your general activity level. If you're losing weight too fast or feeling drained, consider adding 100-200 calories on heavy workout days.
