Unfortunately not. There are dozens of companies reselling "old" Libre 2 sensors for "fitness and health" applications. BG has joined HRV and other semi-bogus metrics as one of the numbers that drive a whole subculture of health data.
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.
