Not that banner ads are known for their accurate depictions of truth and reality (typically they involve conning suckers into playing the easiest flash game ever created in an attempt to sell travel packages), but the specific banner ad seen above is just egregious.
What's with the before and after pics?
"4 weeks later I was bigger and buffer and — oh yeah — I also shaved my chest and got about a decade worth of tattoos all over my arms."
What was this guy thinking? Sleeves? All the fat must've gone from his stomach to his head. If you're going to show off your sexy new chest with a killer swastika tat on your left pec, that's one thing, but you can get sleeves even when you are a "fat slob." In fact, comparing the two pics, the arms are the one body party that doesn't even look that different. Screw the weight loss, you coulda just gone with the sleeves, man!
But that logic would assume that these two pics are the same person, and, they obviously aren't.
