Errors in reporting habitual energy intake.
Seventy-six subjects of a long-term epidemiologic study were selected by random sampling to represent the range of energy intakes and retrained in keeping weighed food records. Their energy intake was measured concurrently with doubly labeled water. For over half the group, errors in reported intake exceeded 20% as compared with the doubly labeled water measurements.
