aha! what great news, jen. Doin' the happy dance for you! Now you can stay calm about the weight/BF, keep eating as you know makes you feel best, exercise as you know makes you feel best, and forget worrying about all the numbers.

I had a similar experience with PP BF measurements and calipers/BIA--not quite as dramatic a difference as 33%/19% tho! That's a pretty stunning discrepency.
Amazingly enough, I had a very accurate BF measurement last summer from my trainer, who just looked at me and told me my LBM--and now I see he was correct. The "very experienced eye" isn't ever listed as an accurate BF testing device, but in this case, it was dead on.
