No I think judy meant not high fat dairy.

I have changed over (with Judy's assistance) and it's been an easy transistion, and it seemed really daunting at first.
I can only talk from experience but I have changed from atkins to SB and lost 13lbs in a month.
Obviously your milage may vary!!

If you're interested then like judy says you should look at the link in her signature, it's a really good simple way to understand what you can have on SB.
