Why use PDFPremium.pro?
Every diet plan starts with one number: how many calories does your body actually need? This calculator uses Mifflin-St Jeor - the formula dieticians actually use - with your age, weight, height, and honest activity level, and gives four numbers: BMR, maintenance calories, a sensible weight-loss target (about half a kilo a week), and a gain target. No crash-diet nonsense, and a clear pointer to a professional for real diet plans. As with every tool here, it runs entirely inside your browser - no uploads, no sign-ups, no watermarks.
