Eating 500 calories and BMR .

Some simple science backed up with numbers.

At less than ~1200 net calories a day, your body will go into starvation mode. Your body thinks it is in a famine and you are starving. Bodily processes will start slowing down to conserve energy. Metabolism drops by approximately 40%. That's the important part. Let's see what this means.

Your BMR is approximately 2000. Probably a bit higher, but let's go with the lowest reasonable number. That means that your body burns about 2000 calories just by existing.

You're in starvation mode. Your metabolism is down by 40%. Before, you were burning 2000 calories just by existing. Now, you're only burning 60% of that due to the 40% drop in metabolism. Your body is burning 1200 calories instead of the 2000 it should be.

This means you can eat 800 more calories a day and lose weight at exactly the same rate. That's a lot of room for proper nutrition.

The 500 cal diet should last no more than three months apparently this starvation mode dosent occur for us larger people for quite a while then the calories will gradually be increased

According to what you posted before (and according to my calculations before) you've already lost 3.5lbs of non-fat while you lost 11.5 lbs of fat. So yeah, your body is already chewing up muscle at a rate of knots, even as a larger person.

This I think is the answer I have been looking for ..... Thank you

So two dozen people give the same answer--that you will lose more weight (and keep it off) long term by eating more than 500 calories net, but only one of them is the answer you were looking for?

You claim you need to lose weight fast for health reasons, yet what you are doing is far less healthy than staying fat. Honestly, if you're going to keep eating 500 calories/day net, it would be healthier to remain at 269 pounds, eat good healthy food and get more exercise. REALLY it would.

Meh.
