TDEE Calculator
Calculate daily energy expenditure (TDEE) and basal metabolic rate (BMR). Plan precision calorie targets and macronutrient distributions for cutting, maintenance, or bulking.
Walking Calorie Calculator
Calculate calories burned walking based on body weight, distance, speed, steps, and incline. Powered by ACSM metabolic equations.
How ToolWingz Health Calculators Work
Every health calculation tool on ToolWingz is built on published clinical formulas, peer-reviewed physiology papers, and verified mathematical constants. We prioritize complete transparency: we never treat algorithms as proprietary black boxes, and we always explain the variables influencing your results.
Metabolism & Energy Expenditure
Energy balance dictates weight gain, weight loss, and athletic performance. Our Total Daily Energy Expenditure (TDEE) and Basal Metabolic Rate (BMR) models implement the Mifflin-St Jeor equation—considered the clinical gold standard by the Academy of Nutrition and Dietetics—alongside Katch-McArdle equations for individuals who know their body fat percentage. These calculations establish realistic, biologically safe calorie targets for sustainable body composition goals.
Anthropometry & Body Proportions
Body shape is defined by skeletal structure, muscle distribution, and adipose tissue patterns. Our Body Shape Calculator analyzes the mathematical relationships between bust, natural waist, high hip (illiac shelf), and lower hip circumferences. It integrates the World Health Organization (WHO) Waist-to-Hip Ratio (WHR) thresholds to evaluate abdominal fat distribution while providing actionable, proportion-flattering styling advice.
Alcohol Pharmacokinetics & Clearance
Blood Alcohol Concentration (BAC) depends on total body water volume, pure ethanol intake, and liver enzyme elimination over time. Our BAC Calculator applies the Swedish National Institute of Public Health updates to the Widmark equation, accounting for distinct biological sex differences in body water ratios and standard metabolic burnoff rates of approximately 0.015% BAC per hour.
Locomotion & Caloric Expenditure
Walking is one of the most accessible and effective forms of cardiovascular exercise. Our Walking Calorie Calculator implements the American College of Sports Medicine (ACSM) metabolic equations, factoring in body mass, speed, walking surface, and uphill incline grades. It also incorporates the Pandolf load carriage model to evaluate the energetic demands of weighted walking and rucking.
100% Client-Side Privacy Guarantee
Your physiological data, weight, age, personal measurements, and habits belong to you alone. Unlike many online health portals that record inputs in tracking databases, every ToolWingz calculation executes entirely on your device using JavaScript in your browser session. No personal numbers or inputs are sent to remote servers, stored in user profiles, or shared with third-party advertising brokers.
Educational & Informational Notice: All calculators, estimates, and data provided on ToolWingz are designed strictly for educational and informational purposes. They do not constitute clinical medical advice, formal diagnostic evaluation, or legal assessments. Always consult qualified healthcare professionals for medical decisions or personal nutrition guidance.

Upcoming Health & Physiology Utilities on Our Roadmap
Our engineering team is actively developing additional transparent calculation tools to address everyday health and lifestyle questions:
Track circulating adenosine receptor blockade across 5–7 hour metabolic elimination curves to protect restorative REM and deep sleep architectures.
Calculate baseline fluid turnover and sodium/potassium requirements based on ambient temperature, humidity, body surface area, and training load.
Target clinical protein targets (1.6–2.2 g/kg), essential fatty acid floors, and glycogen-replenishing complex carbohydrates matched to training volume.
