Energy balance
Metabolizable energy intake can be predicted, but this prediction is unlikely to be accurate and precise unless the subject is in approximate energy balance.
Practitioners should be cautious when predicting metabolizable energy intake, especially if energy balance is not confirmed.
StrongQualifiesmedium confidence
Metabolizable energy intake can also be predicted, as the sum of total energy expenditure plus an estimate for the change in body energy stores during the measurement, but this prediction is unlikely to be accurate and precise unless the subject is in approximate energy balance.
Why this rating
Based on the method's limitations as stated in the abstract.
