How is my energy balance calculated?
Last updated March 11, 2025
BODYSIM implements the most sophisticated energy balance estimation of any app on the market. BODYSIM’s estimate of your energy balance accounts for large and important sources of information and error, including:
- Scale weight, including their bias and noise
- Scale body fat, including their bias and noise
- Fitness trackers, including their bias and noise
- Your anthropometrics (frame size, etc.)
- Your food logging data
- Your DEXA scans
Because BODYSIM implements a detailed scientific model of human metabolism and physiology, it can triangulate the truth about your basal metabolic rate (BMR) and energy balance by considering how all of these noisy observations must come together and evolve in your body through time. Building muscle requires a certain amount of protein, extra energy and resistance training.
