If you whip heavy cream long enough to you get watery butter. The "watery" is still the whey.

But yeah, the calories are an issue too.
5'0" female, 44 years old. Started Primal October 31, 2011, at a skinny fat 111.5 lbs. Low weight: 99.5 lb on a fast. Gained to 109 on sugar cheat. Reset with 85P / 90C / 90F. Currently weaning off fat to 85P / 90C / 60F.
MY PRIMAL: I (try to) follow by-the-book primal as advocated by Mark Sisson, except for whey powder and a bit of cream. I advocate a two-month strict adjustment for newbies. But everybody is different and other need to tweak Primal to their own needs.
