Your prospects think all marketers are major jerks
Because they've become more sophisticated over time, as they’re exposed to same marketing promises/claims
So they no longer respond to any ad that looks like stuff they've seen before...
EG: If everyone is saying "Take X and lose weight"
.... and you say the same in your ad, your message will fall on deaf ears because that promise has been repeated over a million times.
EG: They're tired of hearing "take X and lose weight"
That's a MS-level.... and they've moved up to a level where they want to hear something fresh/new/different...
"Take X and lose weight"
You can say
"NEW health discovery reveals how to lose up to 38-pounds in 7 Short Weeks.... Without Giving up Ice-Cream and Shawarma"
Etc
The trick is to always differentiate your business from the rest.
