My 2 cents. If you have been stuck for months at a weight and you are eating below TDEE then one of three things are occurring.

1. You are recompisitioning
2. You have over estimated your activity level for TDEE calculations.
3. You are stuck due to low carbs and/or stress not allowing for recomp/loss .

Number 3 is most likely. When I would "cut" for weight in the military it was a 45-day process. 3.5 mile run 2x a day with high protein low fat and minimal carb. I would lose maybe 10 pounds during the 45 days and immediately on the 46 day i would do a carb loading day. Over days 46-50 I would lose 20-30 pounds. Just my experience. If you are not doing cardio to any degree then do not expect losing bf under 15% to be easy.
