Tracking what you eat is only useful if the guidance powering it is accurate and reliable. Cal AI's goal calculations, nutrition targets, macro recommendations, and dietary guidance is supported by research, detailed here by our registered dietitians. As the app evolves, we'll keep this page updated.
