I do have to say, that after I pretty much spent the first 5 days trying to avoid starvation (the dig quests saved me, thanks for the tip, I normally don't bother with missions at all) that I enjoy this version more than most, just due to being stuck in the stone age for much longer. A bit of a challenge at last, really.
Also, it took me a while to get a farm running, I just couldn't find seeds anywhere and I hadn't even come across a corn field until week 2. It does give me bit of a sense of purpose, hunting for seeds.
Of course, once one has a farm going and is able to craft enough meat stews, the food is no longer an issue.
Anyway, it seems I had made a mistake trying to loot all the kitchens at first. That's not where the food is. There's much more food to be had in the food piles throughout the POIs.
Conclusion: Yeah, the food consumption is a bit out of whack, but I like it.
