It should also be noted that the boost in fat burning is relatively small. In a typical cardio session burning 20% more fat is almost negligible. For fat loss most studies support weight lifting being superior as it may increase metabolism for as much as 72hrs after training where metabolism boost from cardio is more contained with in the time you're training.

The information is true or at least there is more information saying it's true than not but it's probably not a significant enough protocol to be worried about.
