For my height 1.7 m I would have 10 weigh 115 kg to have a BMI of 40. Bloody hell, I count myself as overweight at the 74 kg I weigh now, BMI 26. Just can't imagine carrying an extra 41 kg!
Doesn't surprise me at all that it would shorten my life. Never mind that but the life one has must be worse as well.
I just did that same calculation. My god. Would I even want to go 10 more years weighing 300 lbs?
I know BMI isn't 'perfect'. I think once you reach a certain weight class it becomes more and more relevant. There's no way more than a few fringe cases of people are 6'+ and 350+lbs of primarily muscle. Even NFL linemen are on average 6'4" and around 300lbs.
Edit: That linked article is incredible. It shows the primary driver of the increased mortality is from heart disease and diabetes. 5x more deaths from diabetes, 3x from heart disease, and 2x from digestive neoplasms, 16x lower respiratory, 5x liver disease. I'm going to continue my good exercise and dieting...
>My god. Would I even want to go 10 more years weighing 300 lbs?
As someone who's dropped from 430 to 330 (6'3" 31). This is always a difficult question. The struggle is real, but even trying to hit the "healthy" weight for my height according to BMI is another 140lb away.
You're going the right way and that is something to be very proud of for yourself. It didn't happen overnight so it won't go away overnight.
Seriously, you should be very proud and I truly commend you. I was 133 pounds when I stopped running track and field. I went up to 200 pounds with some ease. It's been a struggle to return to 150 pounds.
Here's a journal article:

but to summarize BMI vs years lost:
