I don't think the professor (can you give us his name?) would argue that fasted cardio burns more fat. It is in the literature (i.e.
"Lipolytic suppression following carbohydrate ingestion limits fat oxidation during exercise."
Horowitz JF, Mora-Rodriguez R, Byerley LO, Coyle EF.
Am J Physiol. 1997 Oct;273(4 Pt 1):E768-75). However, you would have to ask him very specific questions about cardio. I doubt he would reccomend running sprints on on empty stomach, but walking is probably no big deal. I will say that there are some discrepancies between the forums and what the data show. For example, the cardio on an empty stomach in the am makes a significant difference, but the coefficents are small. I don't remember exactly, but either this article or one of the others in the references indicated that it would take 42 cardio days for the difference between the fasted and non-fasted groups to equal one pound. It still usually just comes down to having a calorie deficit. However, I don't think the scientific studies will ever change anyone's minds on the boards until some magazine does a feature on it that is copied in a bunch of the other mags. Look at glutamine supplementation. There is absolutely nill evidence that oral glutamine supplementation does anything in active/training adults, but it is still being pushed pretty heavily. The stretching before lifting technique was proven to be ineffective, but it took a long time for people to accept it. Half of the people I see in the gym are still stretching right before hitting heavy weights.
