Honestly since a diabetic can be someone 175lbs to 375lbs I can't even guess what his blood work would tell about his health. Risk factors are risk factors, that being that the higher the bodyfat the higher chances of increased inflammation, high fasting insulin, insulin resistance, etc. Is someone with some fat on them going to live to 40? Sure most likely......50? 60? 70?....Quite possibly, especially if the person is active, doesn't have high stress levels, and not eating sugar but maybe just has excess calories causing weight gain...then who knows. Same reason a skinny person who doesn't exercise, has high stress and lives on Jolt Cola may not make it past 50.
Going back to the original topic about linemen and some of the sport guys...they eat like crap thinking they are getting away with it during their playing days...when it could just be a ticking time bomb waiting to go off. An overweight person on whole foods will outlive an overweight person on junk food and processed sugars....mostly due to the insulin resistance factor.
Hell there are some sumo wrestlers who can live well into their 80s....but most have to lose some weight after they are done and still try and keep active. But I find it ironic that most sumo wrestlers have decent blood work even when putting down 20,000 cal a day and working out for 4 hours. Of course they only eat one meal so there might be some sumo form of IF helping to combat insulin resistance. Most of their ill-health starts when they stop competing after 40 and then start eating 3-5x a day, probably because of the non stop insulin spikes and and lack of real exercise.
In the end...isn't life expectancy just a guessing game we play with the genetic factors we are dealt? All we can do is manage the risk factors we know that will decrease life expectancy. Only things we know for sure is that calorie restriction is the only proven way to extend animal life spans in a lab environment.....and high fasting insulin/blood sugar is going to lead to an early grave whenever that may be.....which is dependent on the individual.
