Energy Intake - Steady State & Change Over Time

Measure Definition:

This measurement provides an estimate of the changes in energy intake over time. The method requires baseline information about sex, age, and height along with repeated body weight data and optional physical activity data (e.g., from an accelerometer). The method calculates the changes in energy intake over time that correspond to the measured body weight changes using a mathematical model of adult human energy balance dynamics.
