For a 50lbs weight loss and at 163lbs the numbers don't look that bad. What is your Bench 2RM? If your hitting 205x5 you've gotta be able to hit 225x2 right?
What is your Squat 3RM?
The deadlift drop off is the only one that stands out to me.
Have you tried different eating and recovery strategies?
How much fat are you eating? How low exactly are you keeping carbs?
How long did you give these methods before you decided you'd made no gains?
What does your warm-up look like? Did a doctor diagnose the pec or did you? How many carbs are you eating on training days?
We need more specifics on your training. Sets, reps, frequency, etc...
What do you do on your deload?
Have you had any other tests done? Your thyroid for example.
