Simulating natural conditions? In the wild there is not a ready/steady source of food every 5th/7th day. I did not say starve or malnourished. All of the snake I ever owned were healthy good eaters, proper weight, breeders, etc.
I also would not (should not, lol) give myself all I can eat either. Many are in a race to get their snakes up to breeding size as quickly as possible. Yearlings, get fed 1x per week, 2 year olds, every 10 days, 3 and over 14-21 days. They grow steady and strong. Finally, they get alot less "exercise" in small enclosures, where as in the wild, they move around alot more.
So IMHO, "a bit hungry"= balancing diet with captive conditions
