Health tools you can trust

GoLeanPro was created to make evidence-based fitness and nutrition tools free, fast and easy to understand. No paywalls, no sign-ups — just clear numbers and practical guidance.

Our methodology

• TDEE: Mifflin-St Jeor equation with standard activity multipliers.
• Body fat: U.S. Navy circumference method (Hodgdon & Beckett).
• BMI: WHO adult classification thresholds.
• Weight loss timeline: ~7,700 kcal per kg of body fat.

Editorial standards

Our guides are written from peer-reviewed research and reviewed for accuracy. Calculators provide estimates for healthy adults and are not a substitute for professional medical advice.
