The accuracy of self-reported energy intake using the 24-hour daily recall method has been shown to be consistent across BMI levels:
"Accuracy of recall was not related to body mass index in that the obese men recalled food intake as accurately as the nonobese men." [1]
Accelerometers were used in the Chinese study to measure physical activity:
"No differences in PA [physical activity] and SB [sedentary behavior] were found across different BMI categories." [2]
A European study where the childrens' parents were doing the reporting rather than the subjects themselves concluded:
"The data suggest the belief that overweight children eat more than non-overweight children is not correct." [3]
Studies on identical twins showed that caloric intake didn't account for differences in weight between twins. Specific types of gut bacteria present in low-weight individuals were found to have a protective effect against obesity however. [4][5]
There is little difference between the energy intake of most overweight people and their normal weight counterparts. Factors like gut biology and intestinal absorption play a much more important role.
The Nutrition Science Initiative was developed to address the need for more clinical research in this area. [6]
