Fat people are liars, too

A couple days ago I read this BBC report about a study showing that obese people tend to under-report their sugar consumption on food frequency questionnaires, which could have grave consequences on the validity of epidemiological studies of diet and health. Here’s a link to the actual study.
It just made me think about the OBESITY IS CONTAGIOUS brouhaha a while back and the instantly glad that the copy editors decided not to headline the story OBESE ARE LIARS ABOUT FOOD or something. I guess they learned something.
But seriously, why DO obese people under-report sugar intake? Unconscious wishful thinking? Ignorance about the foods they consume? Extra-bad estimations of portion size? It’s weird, because people in diet/food research know that EVERYONE is pretty bad at this kind of stuff. So it’s strange that they founds such an effect for obese people and not non-obese.

Do we know for sure that urine and plasma levels of sugar behave the same way in obese patients as in those of normal weight? In other words, is lying the only possible explanation? I’m a little skeptical, having seen some pretty badly reported articles about obesity lately.
Kristi - that’s totally what I was thinking, too. Obese often have insulin resistance, for one, and a whole host of other metabolism-based pathways could be very different.

fear of judgment, i think. knowledge that they’ve already been read as obese and trying to convince themselves and others that they still have healthy diets. embarrassment.
in health class, way back when, we had to go a week without eating sugar. it wasn’t designed very well, and most people failed it, but i lied and said that i was successful - because i didn’t want to be The Fat Kid who failed it.
also, finally, i think that in some cases obesity can grow out of a disconnect with food and a highly diet that doesn’t seem at first glance to people to include a lot of sugar, when it really does.
oh, politics of fatness.
