It's a slippery slope, cutting calories. Since we are about the same stats age/weight wise I feel I'm qualified to give you some advice. I went from 250 to 165 over 2 years. The last 20lbs went off waaaay slower than the first 50. When you lose weight, your caloric need decreases. You have to continually titrate your calories down as you go. Luckily this is usually automatic as hunger signals improve and your metabolism gets to working right again. Occasional over-feedings are burned off if everything is working right, but continual overfeedings make you fat.
The best way I found (for me), eat without counting calories, but kind of track what you eat. If you are not losing like you want, ditch something or cut down on portion sizes. ie. less (or no) coconut oil, IF til lunch every day, etc... Eventually you will start losing again, but it will be very slow towards the end.
The ramifications of not taking in enough calories are that you will be constantly hungry and prone to eating something you shouldn't or just feeling plain miserable. Your body will adapt but your brain might not. I have found counting calories to be a very bad way to judge food intake. Food labels are wildly misleading and often just plain wrong. I have found much more joy in counting nutrients using the free nutrient calculator on FitDay - Free Weight Loss and Diet Journal I plan out sample menus and see where that puts me for calories/nutrients for the day. Sometimes something as simple as a handful of almonds or a can of smoked oysters will put you over for all tracked nutrients for the day. In my mind, it's way more important to hit the majority of micronutrients than macros.
