Is obesity ever actually a concern for male ball pythons?

[Lolo76]

My male Mojo Julius is somewhere around 2000g (haven't weighed him in a while), and at only 2 years old has already produced 11 beautiful babies. He's possibly a little chunky, but definitely not obese or unhealthy - just a big boy!! Btw, he feeds on 2-3 live adult mice weekly, and will occasionally take a f/t small rat instead.

I do have a corn snake who's obese, weighing in at a whopping 1190g last time I checked... normal weight for an adult female corn is 500-700g, FYI. She was already that size when I adopted her, and is probably around 14 years old now. So she's lived to a ripe old age, and aside from a fatty deposit near her cloaca, seems to be in decent health. I've had her on a diet for the last couple of years, but so far it's been futile (and pointless at her age).
