It'll now cost a 65 year old couple $275,000 to cover their medical costs in retirement (in America)

If this was the case, it would be evident beyond America. For example, the UK has a very high obesity rate, smoke more and drink more than Norwegians. But still have far cheaper health care.

If obesity and lifestyle was a heavy driver of healthcare costs, you’d see it in the costs of other nations. But the only real correlations we see is that the US is high in both and Japan is low in both. Beyond that, its all over the map.

Intuitively, I agree it makes sense that poor lifestyle results in higher health care costs. Poor lifestyle = more health problems = more health care = higher health care costs.

But that doesn’t seem to be how it works in practice.

Putting aside the issue of foreign nations, just look at the difference between the states.

There are wide variances in the smoking rates and obesity rates by state.

Smoking rates by state.

Take a state like Arkansas or Kentucky. Above average obesity rates and above average smoking rates. Health care costs are less than some states with below average obesity and smoking rates like Montana. If there is a correlation between smoking rates, obesity and health care costs I’m not seeing it.

Some states like Vermont or NH with low obesity rates and smoking rates are more expensive in health care costs than other states with higher rates.

I’m not a health care economist, I don’t know what all the factors are. I’m not sure why the new england states are 9-11k per capita.

The closest thing I can find to an argument is that Utah has low medical costs, and low rates of obesity and smoking. But even with that, their medicare spending per beneficiary is about the same as Arkansas, which has far higher rates of obesity and smoking. Colorado has low rates of both smoking and obesity, but their health care costs are only 5% cheaper than Alabama with higher rates of both. Alabama has lower medical costs per capita than new england states which have lower obesity and smoking rates. Some new england states are urban (MA for example) some are rural (VT).

I have no idea what all that data means. But there doesn’t appear on the surface to be a connection between obesity rates and/or smoking with per capita health spending on a state level.

Generally, I suspect unhealthy lifestyle affects healthcare costs in the same way preventive medicine does.

I.e. medically, the most costly years of life are old age years. And unhealthy lifestyle people have significantly fewer of those. While they may be more expensive while alive, that does not necessarily mean more expensive in total. In the case of preventive medicine, I’ve seen studies saying it saves a bit, and studies saying it costs a bit. I’ve ended up feeling it pretty much cancels out.

Exactly this. This is why the system in the US will never be “fixed”. There is a vast amount of cash being syphoned off.

The best course of action is to hope that blue states and large cities implement meaningful health reform that actually lowers cost. If they do that successfully, it may eventually spread to the national level but there will likely be a 10-30 year delay.

But if CA, IL, NY, etc. pass meaningful health reform and show it can work, it could start the ball rolling.
