totally agree with BtB and 5kg.
I was 175 lbs and had a spine surgery. dropped to 150 lbs. (was 5'11")
My body gained back the weight as fat within a month (and I wasn't eating heavy!).
Took me another year to re-comp to prior muscle and Body fat levels.
I have found recovery takes almost as long as you were out of commission.
i would set my goals at reasonable and balanced strength markers for bench, military press, row, squat and dead lift before worrying about anything else. That will take as long as it does depending on your training, background, etc.
