Why We Built CaloriePuls
Most modern calorie tracking apps are bloated with invasive ads, forced monthly subscriptions, paywalled barcode scanners, and aggressive telemetry tracking that sells your personal health data to brokers.
We believed there had to be a better way: a clean, fast, and beautiful tool where you can look up food calories, calculate your daily calorie needs for weight loss, and track your meals in total privacy.
Our Calculator Methodology
Our weight loss calculator uses three peer-reviewed clinical equations to estimate your Basal Metabolic Rate (BMR):
- Mifflin-St Jeor Equation (1990) — recommended by the Academy of Nutrition and Dietetics as the most accurate for healthy adults
- Revised Harris-Benedict Equation (1984) — the historical standard revised by Roza & Shizgal
- Katch-McArdle Formula — uses Lean Body Mass for greater precision when body fat percentage is known
TDEE is calculated by multiplying BMR by validated Physical Activity Level (PAL) multipliers. Calorie deficit recommendations follow clinical guidelines of 300–500 kcal/day for safe, sustainable weight loss.
Editorial Standards
