Objective To describe energy intake reporting by gender, weight status, and interview sequence and to compare reported intakes to the Estimated Energy Requirement at different levels of physical activity. Methods Energy intake was self‐reported by 24‐hour recall on two occasions (day 1 and day 2), approximately 10 days apart. Weight status was calculated from measured height and weight. EER was calculated for each individual based on 4 physical activity scenarios, and differences in intake – EER and % of EER were calculated using a sedentary activity level. Means and differences were derived using SAS PROC SURVEY. Results On average, reported day 1 energy intake was 100–300 kcal higher than day 2. Comparing intake to EER calculated using a default physical activity level of “sedentary”, we see that overweight and obese groups tend to report intakes for both day 1 and day 2 that are below the calculated EER. Healthy and underweight groups tend to report intakes that are greater than the calculated EER for both days. This could be a result of dieting in the obese and overweight groups, or an increased tendency to under report intakes as BMI increases.
