You can have /r/technology and /r/tech and /r/technews etc…
It’s a problem that resolves itself. One community or the other will “win”.
And if not, whatever. On Reddit, my home city has two subreddits. The content between them is slightly different (different mod teams) and the comments on duplicate posts are different. I subscribed to both to see slightly different opinions and avoid echo chamber.
I’ve been counting calories for the last few months, and that was my big realization as well. I could have easily put down a single meal at a restaurant which is my entire (or more) daily intake now.
More than anything it’s just awareness.
