Not true. A nonfat item with 4 gms of fiber can have up to 110 calories and
be one point. A high fat item, with no fiber, can have a little as 30
calories and be a point.

I have the WW official thing here on my desk. My average calories per point
is 60, because I tend to prefer high fiber foods by choice.

..

Technically that is true, but for all practical purposes it is basically
50
calories per point. I've seen the equation (it's a copyrighted equation,
so
it's listed with the government in a publicly accessible area!). No matter
how little fat a serving of food has, or how much fiber, the points never
vary much from basically 50 calories per point.
