Anything that has the lowest impact that you can stick to.
Why?
cuz your body has been fasting all night while you sleep ...so the first thing you should do when you wake up is get some protein in the system The body needs these essential nutrients
Without a breakfast you are running on empty....your body needs to refuel from the overnight fast
its better to skip dinner than breakfast
swimming...jogging...yoga...shadow boxingSpecifics would be nice breh
Not that hard to think of.... biking, swimming, rowing etc... pretty much anything that doesn't require running or anaerobic outputSpecifics would be nice breh
Bruh back in the stone age humans might not even eat at all for a whole day, let alone get a nice breakfast every morning. Running on empty is fine. My best cardio sessions are fasted
Now lifting fasted 
But just going to work or doing cardio.... it's not that serious.You are talking a bunch of bro science.... give it a try before you knock it. Not for a day, for like a week or two. I promise u won't die
Running on empty? Your body doesn't store energy?
Not great for your jointsWhy not running

It's something you have to ease yourself into & depends on the person's current back, knee & hip condition.
But I see no reason to completely steer away from it. Running outside is great & i really enjoy it. Plus it's a challenge every time I run.
Ultimately it depends on the end goal.
My view is that it's a good adjunct but not the best primary source of exercise.
I think it's thrown around to easily as a solution for weight loss when ultimately there are likely better methods.
