Sure, but gross labor share of GDP is 60% in the US (salaried employees earn 60% of GDP in total) so it doesn't change the consideration that much.
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.
