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.
StrongSupportsmedium confidence
The absolute stated energy contents were not significantly different from the absolute measured energy contents overall (difference of 10 kcal/portion; 95% confidence interval [CI], -15 to 34 kcal/portion; P = .52).
Why this rating
Based on the use of a validated bomb calorimetry technique and a substantial sample size.
