From IRC:

[14:19] so I am having an issue getting unger overhaul to play well with veinminer
[14:20] I set the lose food slowly over time to false becaue it was too fast for my skyblock style modpack as food is super scares and 14 deaths before getting first cobblestone is a bit much
[14:20] problem is when disabling lose food over time it also disabled losing food from veinmining somehow
[15:23] <+squeek> ecoay: HO assumes no hunger loss means hunger as a mechanic is effectively disabled and forces hunger to always be 1/2 bar from full
[15:24] <+squeek> that behavior was carried over from 1.6.4
[15:24] <+squeek> https://github.com/progwml6/HungerOverhaul/blob/master/src/main/java/iguanaman/hungeroverhaul/food/FoodEventHandler.java#L50-L59
[15:25] <+squeek> would probably be worth splitting that into a separate config setting
[15:25] <+squeek> will add an issue for it

Should add a neverLoseHunger config setting or something like that instead of using IguanaConfig.hungerLossRatePercentage == 0.
