There are many ways you can force your population or employees to be less fat.

Google could ban fatties from coming into the office incentivising fat loss, you could force fat people to self isolate or not allow them to travel, also to incentivise healthy loving and make it shameful to contribute to the obesity epidemic.

This is all ridiculous, but the moral logic would be similar. The same is true for driving and weapons, which are dangerous.
