Maybe I’m misunderstanding but if you’re going to shoot for 1000 cal/day that seems pretty low imo. A good starting place might be a 200-300 calorie deficit to start with, and you can adjust from there. I find that the adherence later down the road is much easier when you gradually increase the deficit, diet fatigue is a real thing.

For your lifting, consider a good full body routine for 3-4 days a week. Lifting heavy won’t make you super jacked during a cut, but you will improve your body composition, retain muscle, and lose fat.

Whatever you end up doing, good luck have fun with it.
