Stupid advertising slogan

The one for Quorn, where Mo Farah is running a burger van has annoyed me for ages. The slogan is:

"When healthy food tastes great, you forget it's healthy"

This slogan makes more sense if you invert it completely:

"When unhealthy food tastes great, you forget it's unhealthy"

"When booze tastes great, you forget it will give you a hangover"

"When you're high on opioids, you forget that an overdose can kill you"

Etc etc etc.

Hang on a Mo'
