If I were you and feeling this way I might stop making bullet proof coffee and stick to some cream and not add the extra fat. If you want your body to use your fat for fuel push it in that direction and give it less additional dietary fat.
Also, you can’t get clear answers because there are many variables and everyone can experience things differently and on different timelines. You said you don’t want to start exercise but maybe just walking would jump start weight loss. I have personally not lost more than about 10 lbs in four months but today I got myself into a size 14 pants and I started at an 18-20.
