calories

This library provides functions to estimate energy expenditure in calories. The simpleCalories function uses MET values, body weight in kilograms, and time. Advanced models process GPS coordinate arrays: pandolfCalories (with terrain and downhill correction), lcdaCalories (requires BMR parameters via Mifflin-St Jeor equation), and minimumMechanicsCalories (simpler alternative without terrain). The calorieEnsemble function runs all models for comparison. Additional features include listing available models, Koa middleware for browser use, and sample GEOJson GPS data. A dependency-free ES module for walking, hiking, and rucking activities.
