Calorie Definition

Farmers and Calories
- German farmers were the first to use calories to measure livestock feed efficiency.
- They tracked input calories versus output (meat/produce), realizing animals don't absorb all calories.
Bomb Calorimeter
- Wilbur Atwater pioneered using bomb calorimeters to measure food calories.
- A bomb calorimeter burns food in pressurized oxygen, measuring the released heat to calculate calories.
