    The same could be said of the logs here. Not everyone weighs all their food, not everyone logs correctly even if they do weigh things, not all food is exactly like the databased caloric values. It's all an estimate. Even if there was a lab-fed test group, it would still be an estimate. The '3500 calories to a pound' is an estimate, too. You don't need perfect accuracy for the info to be useful.

    Yes, and we have varying results here on MFP. If however a researcher is attempting to answer a fundamental question, for instance, if McDonalds is truly fuelling our obesity epidemic, I want to see a little more rigour.

    The data spread shows how little difference various diets make (Keto over HCLF for instance), and self reporting only makes the results more ambiguous.

    If there is a magic bullet, IMO, it won't be found with dietary self reporting.
