Health Calculator API
A complete health & fitness calculator suite in one API: Body Mass Index with category and healthy-weight range, Basal Metabolic Rate (Mifflin-St Jeor and Harris-Benedict), Total Daily Energy Expenditure with weight-loss/gain calorie targets, macronutrient splits (balanced, low-carb, high-protein, keto, endurance) with fibre, U.S. Navy body-fat percentage, ideal body weight across four classic formulas (Devine, Robinson, Miller, Hamwi), and daily water intake. Every endpoint accepts GET query parameters or a JSON POST body and works in both metric and imperial units. All computation is done locally with established public-domain equations, so responses are instant and the service is always available. Ideal for fitness trackers, nutrition apps, telehealth and wellness dashboards.
