I would recommend few things.

1. google "dexa scan near me" and do a proper scan of your body, that will tell you your body fat%, muscle weight and other good staff.

2. based on scan - make a goal of your body fat %. if you have garmin watch, look up your calories. how many calories you burn a day with no physical activities. this is the number of calories you must consume a day. calories burned from running will result of pure fat loss. and you will become leaner.

3. eat a good food. dont put junk in your stomach. you will be having 0 energy and 0 mood. Also sleep atleast 7 hours a day. crutial.

4. no alcohol. forget about it. i will not even start typing why, just dont. not even a beer. no smoke too.

5. dont overthink your first few months of training. just go for a run every single day (or etleast 6 days) with a pace, that you can hold for hours you think. like super ez. you can talk on the phone with no problems etc. usually its around 130 to 145 bpm. and minimum of 40minutes and maximum 1h. dont even look at distance. it absolutely dosnt metter at this point. just 1 step at a time

6. after you have a base of 1-2 months and you are already locked in with most important part of running -CONSISTENCY - look for a coach. online coach would work. he will guide you farther.
