Didn’t mean to suggest that LC to HC is per-se a bad thing. Obviously a lot of folks around here swear by all-the-carbs, I just don’t subscribe. The post title (“…despite positive changes”) kind of implies that HC is innately the better choice, and that’s what prompted me to post. I just wanted to suggest the possibility that perhaps your health is more robust on lchf which led to better bike performance. I generally feel worse on carbs, but that’s me. It could of course be all-manner of other things in your case.
