Same weight, lower BMI

[Simplyfiona]

My wt started to drop, but now my wt seems to remain te same, but my bmi is decreasing. I know that this means I am replacing fat with muscle, but it's still a little frustrating. My clothes are all looser, and after switching to a smaller pair of pants, I've had to add a belt. I would still like for my wt to go down. Has anyone had this problem? What did you do? I dropped 15 lb befor hitting this stage. My blood pressure has also gone down. I used to be borderline hypertensive. Now my bp is ideal.

Color me confused; how has your BMI gone down?  Given BMI is strictly a measurement of height versus weight, regardless of whether you're 10% fat or 45% fat at any given weight, your BMI will remain the same.

The above said, the BMI calculation can be so horribly incorrect as to render it utterly stupid and irrelevant, and should be completely ignored.

I have been doing the same thing on and off.  I don't know if this is the right answer but it was for me.  I stopped being over worried about what my weight was on the scale.  I am healthier, this I know.  I look good, people have started to comment as such,  Fat % is decreasing.  Once that is in a healthy range..  I am not as worried if the scale says I am over the issue about not being the number I wanted to be. 

I have gone down 6 pant sizes, dropped 40 lbs, have more engergy and more happy.  So what if the scale says 161 and the chart at the doctor's office says 130-159.  As long as my lean mass stays up.  I'm a happy girl.

Looks like you’re mixing up BMI and BF (body fat). If your weight remains the same, your BMI will also remain the same. I assume you are using a Fitbit Aria scale (or similar) that gives you an estimate of your BF %.

I think that you should congratulate yourself. You are now healthier than before. 

Your BMI goes down when your weight in relation to your height goes down. And, even though muscle is heavier than fat, if you've lost fat, your weight will be less, so your BMI will go down. This is a good thing! 

Now, to keep losing weight, you have to increase your movement by 5-10% and decrease your intake by 5-10%. Do this, and you'll lose more weight. Try the 5 and 5 approach for 2 weeks and see what happens. If you are still on a plateau, try a 10% reduction in your caloric intake and increase your caloric burn by 5%. If you keep increasing the increments by 5% and waiting for a couple of weeks, you'll soon see that one or the other will reflect lower weight on the scale. Just be sure you don't reduce your calories by too much, or your body will start to feed off your organs!

@Ukase, either that or leave the food the same and increase the activity.

I thought I mentioned that...if not, yeah, that works, too. (unless you're making errors on the calorie logging.)
