I was under the impression that the insurance companies use advanced algorithms to determine what each individual should cost to insure. Since they are a for-profit company they want to make sure that in the long run they make a profit on each person they insure.
I would imagine lifestyle (which includes smoking and obesity) would be included in the algorithm along with family medical history, personal medical history, the area you live in, your race, gender, etc. An obese smoker with a family history of cancer would be more likely to cost the insurer more long-term than a person who has never smoked, is in the normal range for body fat, and who's family normally lives into their 90's. There will always be exceptions on both sides (the smoker who lives to 100 and the athlete that drops dead at 25) but they don't base these things on outliers.
I don't have a problem with your insurance cost being based on what the insurance companies expect to have to pay out based on their algorithms. If they want to give me a full medical and do blood work before insuring me go right ahead.
So what happens if you don't fall in the normal range for weight but have never yet made any health claims? Does that make it a bit cheaper like car insurance less payments for no claims.

I know what it means.
I just thought you meant that I was trying to excuse my choices by working an angle, so to speak, which I had already mentioned might just be the case.
