Need some reassurance with no weight loss

Thanks for all your input. I guess my main question is once you set your cals/day, how long does it take to see any results. I have been stuck on 210-211 for more than a few weeks. I find it hard to eat 1890cals per day and if I change to 20% then that would mean eating more calories.

Does it seem odd that I am eating at or near my BMR? (1833)

Do you agree that I should use the custom setting for goals instead of letting MFP calculate?

If I eat below 1800 calls will I go into starvation mode?

20% deficit would be ~2100 calories. I do understand that appetite can decrease with age, so you might find that eating calorie-dense foods will work well for you. Most people find that eating a large volume of food keeps them fuller even if they aren't eating more calories. So if you've been eating low/no-fat versions of things, you could try the regular kind and see how that works for you. I 2nd logging more consistently so you can truly see your eating patterns and how they correlate to hunger and progress. I would recommend going up to 2100, that way you will have an easier time reducing your intake while still fueling your body as much as possible.

After a few weeks of daily logging (if it's easier, try pre-logging foods you know you tend to eat every day, or even pre-log an entire day - I do this sometimes when I am going to be pressed for time) and eating close to your target each time, assess your progress. Scale isn't the only measure to use, how clothes fit and how you feel also are worth noting. I don't remember if I lost much the first few weeks back when I first started years ago, this time around I think I saw results because I wasn't eating enough. But you need some consistency before being able to figure out what is and isn't working! If you eat 2100 daily and you are not noticing any changes in weight, clothing comfort, or any other potential signs, go down to 2050 or 2000 and monitor for a few weeks. Keep this cycle going until you start getting regular results.

Just a thought after seeing the water retention comments, you might want to try drinking a bit more water even. 6-8 glasses for me is not at all enough, my urine winds up being very yellow still. My goal is drink until urine is pretty clear, and not drinking enough water can affect water retention levels. especially if eating a lot of sodium; I didn't take note of whether you're tracking sodium and how much you intake, but if you're regularly over your goals then that might be what is causing most of your lack of results. Although any TDEE estimation is just a best guess, so you need to adjust up/down as you monitor your progress!
