While I was never your size, I was at one point 280 pounds.
I can tell you from experience, assuming your metabolism remains constant (that is you are not comparing apples to chicken breasts) you always lose more weight eating less. My metabolic rate starting out must have been around 3k cal. Most days I would barely eat, because frankly I was so ketogenic my body was just shedding fat for energy like crazy, GNG was constant, and I had no need for fuel (diet). Quitting carbs allowed my insulin levels to drop and glucagon to rise enough so that my body was just like "what the HELL are we hording all this fat for? let's eat this, not food!!"
which is, probably the first time ever my body could "see" my fat AND wanted to make energy out of it.
As a result, I lost weight like crazy, and was the low 200s within a couple of months. I would have no appetite, eat maybe eggs for breakfast (if I could stomach it), a bit of meat for dinner and lunch, under 1000 cal no doubt... and lose weight very fast.
I did not do any of this "keeping my fat up", with swallowing oil, forcing myself to eat... because I discovered the less I ate, the faster I lost weight, and those people who were obsessed with forcing food and "keeping up fat" by pouring several tablespoons of oil on veggies often did not.
I know metabolism and weight loss is not a simple matter but
most of the time a stall is resolved by eating less. Most people who perceive themselves to be eating very low calories yet not losing weight, actually arent. Alternately, they count only some days, "relax" other days, therefore are not consistently making a deficit.
Calorie counting is a skill, it takes a long time to get good at it. Also, under eating to lose weight is something that must always be a priority. One cannot do it one day, then "relax" and expect it to work, because on the "relaxing" days you will eat a lot - the body doesn't like to lose at a rate we want it to.
I know you are taking coconut oil, several tablespoons a day... if I were you I would replace fats that already exist in my diet with the coconut oil (if you MUST take it you should replace fat calories with it, not add them in). See if that helps your stall.
