How "Heart-Healthy Whole Grains Make Us Fat" (gnolls.org)

Fascinating study results involving obese teenage boys. Feed them three different breakfasts, with identical caloric value, but composed of different food types (low, medium, and high Glycemic Index foods). Monitor blood chemistry and subjective hunger perception. Feed them the same meal for lunch. Let them eat anything they want after lunch. Measure how often and how much they ate. Monitor total caloric intake.

These results speak for themselves:

“Voluntary energy intake after the high-GI meal (5.8 megajoule [mJ]) was 53% greater than after the medium-GI meal (3.8 mJ), and 81% greater than after the low-GI meal (3.2 mJ).”
[...]
“In addition, mean time to the first meal request after lunch (2.6, 3.2, and 3.9 hours for the high-, medium-, and low-GI meals, respectively) differed between test meal groups (high GI vs low GI; P = .01; high GI vs medium GI, not significant).”

That’s not a misprint. People consumed 81% more calories during the five hours after eating instant oatmeal than after eating the same number of calories as an omelet and fruit—and 19% more calories after eating steel-cut oatmeal than after eating an omelet and fruit. (Note that the hunger curve for both kinds of oatmeal was rising precipitously at 5 hours, whereas the omelet + fruit curve flattened out. Do you ever have to work late? Is dinner always five hours after lunch?) Furthermore, the omelet-eaters took 50% longer to request any food at all.

So, according to the study, the modern "heart-healthy" oatmeal breakfasts that we keep hearing about, can make us hungrier, want to eat more often, and consume almost twice as many calories following the meal when compared to the shunned egg omelet.
