>The rats fed HFCS for 24 hours per day, which should be expected to be fatter, were not. They weighed less (470 grams) than the rats fed sucrose for 12 hours per day. So these results are inconsistent.

I don't see why you would expect those to be fatter; the data point is completely separate. Common sense doesn't apply in biology - any number of factors could cause the results to reverse on a 24 hour feeding schedule.

Humans don't follow a 24 hour feeding schedule, as it happens.
