This is my FINAL cutting post, I promise. So bear with me while I ask my last question.

All this cutting of mine has been a result of a big beach trip I have planned with my girlfriend that is now coming up in about two weeks. I´ve made some good progress but I´m not yet where I want to be. I need to drop several more lbs here before I see her. (I´m currently about 176 lbs).
I am travelling until then and I don´t have access to a gym so I´ve been doing pushups and ab work in the evenings.
How should I do these last two weeks? I´m thinking of dropping my calories really low - like 1500 per day or something- which I know might result in some muscle loss but I figured if I was doing pushups these might limit the muscle loss? What do you guys think? I´m willing to lose a bit of muscle if it makes me look a bit better leaner with my shirt off, so I figured that a very restrictive diet would be the best approach.
Is a very low cal (and low carb) diet the right approach? And how frequently should I be doing sets of pushups and ab work?
Please pardon my naivete on this one and I´d be very greatful for any advice. Thank you! Also, please refrain from making comments about how I should stop cutting or any other criticisms like this. This is my call, and it´s the right decision for me at this time.
