Interesting, though to be honest I’m wary of any study using surrogate endpoints like this (especially bone studies). It’s not like they measured bone density (which isn’t evena good measure of bone strength), or show long term increased risk of fracture. I think the authors are pretty clear, though… this decides nothing, and rather suggests more research should be done to see if there actually is a bone risk. It could be these are totally normal changes based on what they were eating (and who knows what any of them were eating… there are really bad ways to do low-carb/keto just like any other diet).
