ScienceNews - Certain Carbs Boost Fat Burning
Building on research that showed that a lot of fat burning happened on an empty stomach (e.g. before breakfast), researchers hypothesized that eating carbohydrates that don't readily break down might also result in burning more calories. Researchers took (only) 8 women who weren't overweight but had little structured exercise in their lifestyles and had them repeatedly come into the lab for a day to eat breakfast, rest, exercise, eat lunch, then have their calorie-burning monitored into the afternoon. On different days, researchers altered the carbohydrate portion of the breakfast to be either fast-burning or slow-burning carbs, those with a high glycemic index and those with a low GI. Other than that, the caloric intake and carb-fat-protein proportions stayed the same. The women with the slow-burning carbohydrate breakfast burned 2-3x more fat during the afternoon than those with the fast-burning ones.

No comment. I believe it. the only thing that sounds weird is them thinking that slow burning carbs would be the same as a fasting state. i would think that the body would take into account the hormones secreted by the digestive system signaling that there is fuel being processed and thus it can burn calories at a higher rate, I'm not sure how the fasting state is mimicked here.
You're right to be suspicious-- I was being too loose with language. I should have put that this study shared similarities with the findings of earlier ones that had participants with empty stomachs.
