For lifting? Stay at a weight you can do with good form, but try to progress with either weight, reps, or less rest time over time. It’s the relative progress that will make a difference, not the absolute numbers, if that makes sense. I just wouldn’t go crazy and add two hours of cardio or 90 sets of anything or something - you can’t do that forever.
In terms of food quality, I think you’re right on point, and quantity has you losing almost 2 lbs a week - which is on the high end of what’s realistic, especially since your weight had already somewhat stabilized, so I think you’re right on track. I admit I didn’t do the math to see where we land with calories, but yours ain’t broke so we don’t need to fix it. If we really stall and don’t lose anything for 2-3 weeks, let’s take another look.
For myself, I tend to have one night every week or two where I’ll trade my calories for something lower quality - so instead of chicken and rice it will be a burger (so not a 1:1 trade, but not a full-blown eat whatever I want). I also have a few drinks with my wife once a week or so. These are just for sanity! Don’t feel like you have to do that stuff until you want to, but don’t be afraid to have a “normal” evening when you want it either - I think people with stress (you know: parents with jobs!) have to find a medium; activity and diet you can live with, no earth-shattering cheats, but some grown-up relax time.
Anyway, sorry for the ramble, but I think you’re right on track. There’s plenty of folks much smarter than me to help when you do actually get stuck. I would suggest the training log forum as well. You don’t have to write everything you do (or you can), but it’s just a spot for you to write what’s going on and a lot of really experienced folks can either reassure you that you’re on the path, as you are right now, or help you with minor tweaks you might need in the future.
