There's a YouTube video with almost identical ingredients. Honey rather than syrup (something needs to give the yeast its sugar kick) no flax seeds, and your choice of sweetener (I used Erythritol) but apart from that, identical (though the proportions might not be.)
I gave it a try, but my bread maker's belt decided to give out part way through, even though it had worked fine on a dry run. So I'm not sure it got kneaded properly, and it didn't rise as much as I expected. The result was a bit crumbly, but it tasted like bread. And, in theory at least, the few carbs you do get from the honey or syrup don't translate to net carbs because the yeast consumes them. Indeed the sweeteners are 100% pure carbohydrate, just of a sort that we can't digest, so they're 0 net carbs as far as we're concerned.
30 quid for all of the ingredients, some of which will last about 5 loaves, while others will probably do hundreds. I've finished the first loaf, but I'm still waiting for a replacement belt for my bread maker to arrive before I can make another. I'll be going into production and freezing a few, then.
