OK, I just compared both boxes. SBD chocolate PB bars, and zone perfect bars.
Both have 15g protein
Each is within 1g fat content (SB bar 6g, Zone bar 7g)
Both have 21g carbs
Unfortunately the zone box dosn't give breakdown ie fiber, sugar, etc.
There is some fiber as I can see oat bran etc.
The biggest difference I can see is that the SB bars have sugar alcohols ,
and the zone bars use glucose-fructose (sugar) and no suagr alcohols. From what I've read a long time ago, sugar alcohols are partially absorbed as carbs, but n ot fully. So, in fact, the realized carb content of the SB bars may be slightly less.
The small amount of glucose /fructose in the zone bars does not make me crave; it's extremely filling and satisfying. I really hope they don't end up being what's giving me the stall as I have a trip to Toronto planned along with a conference and they would be so handy on the trip!!! But like I say, I am doing a personal experiment this week; if the scale still refuses to budge, I WILL cut them out next week to see what happens!
Thanks!

Update: down 2lbs! wooooo-hooo! So I am going to continue to watch calories along with SBD principles and see what happens. Hopefully I`ll continue this downward trend
