Well it depends. Your goal is to lose 53lb in 23 weeks. That's about 2.3lb per week, which I think it's personally on the "highly dedicated, never cheating, no Christmas eating or beer drinking ever" category since that's about 1250calories in deficit per day.
The real question are:
1) What's your age, gender and height?
2) Why do you need to lose that specific amount of weight?
3) Is your work week 5 day or 6 day? If you are at work at 9AM, a 5 day 56/hour workweek will have you leave your work at 8PM. You could lift from 7:30AM to 8:30AM or 8:00PM to 10:00PM no problem. If it's a 6 day workweek, it's much easier.
4) Before you sign up for the gym, be sure to read the OP. Most people will recommend you to do Starting Strength and they wouldn't be wrong, but in order to do the program, you need to have access to a squat rack that is free weight, not on rails and a bench for bench pressing. Be sure the gym you sign up for has that stuff
