True! And, aside from people with chronic conditions like diabetics, who are forced to know how their glucose levels work, nobody uses those. So it certainly does change the cost, but I don't think it would be any more useful in the US.
To correct this, though. You can buy all those in the US as well. Holter and FirstBeat are selling clinically validated and FDA approved mutli-lead ECG, Derxcom is selling an over the counter CGM, as is Abbott with the Libre 2, and a Chinese company has recently joined there, too.
Low calorie meal replacements are all over the store, too.
If you're a member of this orthorexia/orthovivia crowd, you have the same access to tools as you do in the EU, often more so.
What was the potential harm that was greater than the reward?
It’s probably very low in the context of CGM and diabetes as the potentially harmful treatments require prescriptions.
Device prescription requirements are usually due to product labelling and the manufacturers application. There are OTC fingerstick glucometers and CGMs approved.
It's like, not being obese enough for your insurance company to pay for medical intervention doesn't mean that your weight is optimal enough to enjoy a long retirement.
