Usually a deficit of about -500 calories/day is recommended. So if AMR = 2500, try eating 2000. 3500 cal = 1 lb fat so that is 1 lb/week loss. In practice, AMR is only an estimate, calorie and activity logging can be wrong, everyone's metabolism is different, and nothing ever works linearly, so at best that's an average trend to shoot for.
