There was a temporary allowance for compounding it due to sustained manufacturer shortages but that is in the process of expiring.

Your linked article says: Obesity adds between $147 billion and $210 billion to annual U.S. health-care expenses, increasing an average adult's medical costs by 42 percent — an estimated $200,000 over a lifetime.
Since annual GDP per person in the US is roughly 80k USD and average life expectancy is also roughly 80 so roughly 6.4m USD GDP per person lifetime. 200,000 USD over 6.4m would imply over 3% of GDP, which seems more reasonable.
The US is spending roughly 15% of the GDP on health. If 1% of GDP is due to obesity then this is 'just' 1/15th of the overall health spending. If 3% of GDP is due to obesity then this is 20% (3/15th) of the overall health cost in the US.
