Fat loss product for women

I've found Trainee Keto that I can't get below 9-10% body fat on diet alone (you can only reduce your calories so much, or you begin to eat up muscle)-I have to add in cardio if I want to continue losing. When I bulk, I usually end off around 14-15% body fat, and I can diet off the first 5% or so, but then I hit a plateau that only 3-4 days per week of cardio can cure (20-25 minutes per session). Then, the next plateau for me comes around 8%. If I want to go lower, I have to up my cardio to 4 days per week, for 30-40 minutes per session.
