What about just cutting down the amount of fat and continue at that pace? When I stalled on my weight loss I added back some carbs (sweet potato mostly). Also added some simple High intensity sprints a few times a week and went to a 16 hour break** between dinner - brunch. Some people stall because they don't consume enough calories and starvation mode kicks in. Really just requires trial and error on your part.
** I didn't say Intermittent Fast because everyone then jumps in and says it isn't for the ladies.
