My BMI went down in the last 2 weeks

2 weeks ago, my BMI was 43.8 since my weight was 271.2 on the doctors scale and as of yesterday when I weighed in on my household scale (naked) it read 266.6 so I realized today my BMI is now 43  I'm proud of myself. I also realize that with clothes on I am most likely going to weigh in about 268 on a scale, but that isn't too bad. I prefer to weigh without clothes on. I think I get a better idea on where my weight is at. 

Which do you all prefer and trust when you do your weigh in's?
