Most TDEE calculators just spit out a number and leave you guessing. I wanted one that shows the math behind every metric and explains what it actually means for your goals.
What it does:
- TDEE (Total Daily Energy Expenditure) with all 3 major formulas: Mifflin-St Jeor, Harris-Benedict, Katch-McArdle
- BMR, macro split, calorie deficit calculator, protein intake estimator
- Each result includes plain-English explanations, not just numbers
- 43 static pages covering every calculator variant
Why I built it: I was tracking my own calories and kept bouncing between 5 different calculators. None of them explained the why behind the numbers. So I built one that does.

All calorie formulas verified against published research. Built with Next.js, deployed on Cloudflare Pages.
