energy balance
Intake equals expenditure
Energy balance is the relationship between energy consumed and energy expended.
In nutrition and physiology, it determines whether body weight remains stable, increases, or decreases: To lose weight, you need a negative energy balance.
The concept applies broadly—ecosystems, buildings, and the planet itself have energy balances, with inputs and outputs that may or may not equilibrate.
