When low hunger debuffs are active, there seems to be ice on the player model

What version of Minecraft is this and what mods are you running?

Version: 1.12.2
I am also having an issue with the Well Fed effect not working. I ended up disabling it since i have health regen disabled in my pack.

Pack: https://minecraft.curseforge.com/projects/primal

@Krhymez What is wrong with the well fed potion?

It just does not take effect when eating. It works in its own instance but in the pack, i just does not seem to work. I thought i may be because animania has food buffs, but even if i disable those... it still does not work. I tried to trouble shoot it, but it is on my end. Like i said, if i use the mod with no other mod it works but not in the pack.

@alexbegt I can not figure this out, now the "nausea" effect does not active when low health. It says nausea, but no swirls happen. I know it may be a conflict in the pack, but if you have any insight on this, i would appreciate it.

Sorry I know this is a year old, but I figured I'd shed a little light on what's happening, at least with the first issue.

@Krhymez That pack you have/had is having experiencing potion id conflicts. That ice effect on the player is a potion from Twilight Forest. Adding something that will extend potion ids and/or manually adjusting potion ids in the various configs will solve the problem.

The second problem of the nausea effect not working is a separate issue, which seems that alexbegt has fixed it: 182
