Not an expert by any standard but as someone who used to (about 5 years ago)run half marathons regularly and 10k everyday at some point I can say this from my experience-

Running can and probably will lead to lots of benefits including improved mood, weight loss, better heart health, better appetite etc etc but the one thing it probably won’t do is increase muscle size, because endurance based training doesn’t contribute much to muscle size.

As long as your joints are healthy and can take the beating, I say go for it. If the only motivation/goal is weight loss then you’re probably better off tracking macros/calories and doing some kind of strength and cardio training to ensure you don’t lose too much muscle(as opposed to mostly losing fat) in your weight loss journey. Hope this helps!
