Hi there. I just read through your log and I can feel your frustration with lack of weight loss. I think it's a great idea for you to go back up to "maintenance" level for a couple weeks. The NROL4W workouts are very metabolically taxing, especially if you're also doing HIIT. You're putting yourself at a pretty good sized deficit if you're eating only 1600-1800 calories.
How many complete rest days are you taking a week? See how your weight goes at the higher calorie level. If you still stay the same weight you may even consider upping calories a bit to see if it truly is your maintenance level. If you are carrying as much lean mass as you suspect, your maintenance level is higher than the average woman and you are possibly putting your body into too deep a deficit for it to let go of the fat. Keep experimenting, you'll find your sweet spot.
Oh, speaking of sweets...calories are calories. If you eat some Peanut Butter Puff Cereal w/protein powder while staying within your calorie range...it's all good.
