Wild hogs tend not to become overweight. Some in captivity may do, and it’s possible a hog recently released from hog care, for instance, may continue to eat more than it needs for a while, but will also have other distractions so it’s weight would hopefully regulate. An older hog may rely more on supplementary food than wild food, so be seeming to eat more than others may do.
The male hogs who may have spent a lot of time chasing the females, and so lost weight as a result (not always enough time to eat), will probably be wanting to put it on again now (pre-hibernation). So probably eat more.
But, hogs pretty much know what they need, so I would just keep offering as much as they eat.
