Kids burn more fat, and need more fat, than adults

Hogwash.

"Children burn more body fat day-to-day than adults do, underscoring their need for a little extra fat in their diets, according to researchers."

There is zero need to feed kids "a little extra fat in their diets" if they are already extra fat in their bodies.

If they need fat, they will use the stored stuff.

If they are not already too fat, it is most likely that the body fat they have will suffice.

The advice of these researcher is dangerous, IMHO and further underscores the need to shut out the noise of the experts.
