Adherence
Obese individuals selectively underreport high-calorie, 'bad' foods (cakes, snacks, sodas) while reporting low-calorie, 'good' foods (vegetables, fruits) with similar accuracy to lean individuals.
When tracking your diet, you are likely omitting snacks, sodas, and high-fat foods because you view them negatively. To get an accurate picture, you must record these items honestly, even if you feel they are 'bad'.
GoodSupportsHIGH confidence
It has become clearer that low-energy reporters often fail to report those foods that have a 'bad' or even 'sinful' connotation (20)... In a large U.S. survey... the following were among the foods less likely to be reported: cakes/pie, savory snacks, cheese, white potatoes, meat mixtures, regular soft drinks, fat-type spreads, and condiments (21).
Why this rating
Supported by specific survey data (references 21, 22) comparing reporters vs. non-reporters.

- Obese individuals systematically and significantly underreport their energy intake compared to lean individuals, with underestimation ranging from 30% to 47%.Good
- The multiple-pass 24-hour recall is the recommended method for estimating energy intake during obesity treatment because it minimizes underreporting compared to other traditional methods.Good
