Energy balance

The absolute stated energy contents of restaurant foods were not significantly different from the absolute measured energy contents overall, with a difference of 10 kcal/portion (95% CI, -15 to 34 kcal/portion; P = .52).

Practitioners can generally trust the stated energy contents of restaurant foods, as they align closely with measured values.
