Possible to still lose?

Congrats on the progress. It took me about 18 months to lose 35 lbs. I personally don't think its good to be in a caloric deficit for an extended period of time ( for me that number was 12 weeks). Your body is very good at adapting to your current diet and exercise routine to maintain energy.

What worked for me is that I would focus on losing for 12 weeks or so and then for the next 4 weeks look to just maintain, allowed my body to reset and adjust to my new calories and workout level. I then would recacluate my macros for a small deficit and do it again for 3 months, and then another 4 weeks of just maintenance.

This seemed to work, everytime I reset and started up again, I would start to lose weight again. Also, refeeds helped a lot. Won't go in to the details, you can google it but it certainly helped and kept me sane. Goodluck!

12,000 is awesome! Maybe add a bodyweight program 2 or 3 times per week. Nerdfitness.com has a good one.
