Listerine strips or Listerine mouthwash generally help. Also drinking more water helps as you're weeing out the ketones rather than breathing them out which is what the nasty ass smell is
i feel paranoid when i talk to ppl wondering if i smell lol, its really hard for me cause i have this obsession about peoples teeth and mouths lol im always brushing and using mouthwash and need to have perfect teeth lol, thats the first thing i look at in a man is his mouth lol, so having this nasty taste is really gettin to me :0
