Everyone will be different especially due to the amount of muscle you have. Some will do best at close to zero carbs and other can get away with more than 50g of carbs a day maybe even 75 and still be in keto. As a general rule of thumb you would subtract the fiber from the overall carb count, however anecdotally i have found my best results came with nearly zero carbs. Another thing to consider is goals, because it is far from optimal to train without carbs. The anerobic system thrives on carbs. I have and will continue to use keto as a tool, especially for mini cuts, but I have found out after a lot of trial and error that it is not optimal for anerobic work. The short of it is that you should try to see if you stay in keto while including that bread. If you need a crutch while transitioning into keto from a carb filled diet, things like low carb breads and wraps can be very helpful. Also every now and then if your craving meals with breads, these things can help a lot.
