I only used the bread on occasion. I happen to just like the simple ground flaxseed off a spoon (better than metamucil

).
I wasn't allowed restricted items while on IP phase 1, ever!, so, for me, I waited until my sixth or seventh month just as I was starting phase 2 and just made sure my other IP packets were the lowest possible on those days. I was really just making sure my net carbs were about 25 to 30 a day. I figured if it fit in that day I would have it.
I wasn't worried about the added protein from the egg, I need a bit more. I also didn't worry about the added fat. I was told to increase my fat and was still losing so, on days with the slice of bread, I would just go back to the more normal olive oil guideline.
I didn't not let it replace a packet, there just isn't enough protein in this to make that exchange. I also used it with a meal, usually in the middle of the day.
Again, I didn't do this everyday, I was using the ground flax seed by itself more regularly but, the bread was a treat on a very occasional basis for me.
Other people used it much more regularly but, I can't say how they did it or what they traded off.
