When would you start being concerned that someone’s fat intake is too low? Would 30g a day be ok if it fits the person’s preference? 20g? If bodyweight is relevant let’s say it’s a 200lb male. What about omega 3 intake being too low? Would that omega 3 answer change if the diet is vegan and has no source of EPA and DHA? ---

We don’t really know, as this is almost never seen in those from deliberate dietary restriction in those with a functioning GI system. I’m not suggesting you try. I’ll concede I don’t really know how low someone can go, as it will vary with the person and how long they’re going to be eating this way. I would never recommend 30g of fat a day for intake without medical supervision. It’s not sustainable anyway and I do think there’s some risk of nutrient deficiency at that level. Again, most people will not be able to do that for very long, so it’s sort of a self-correcting problem. Someone may be highly motivated to try however, so again I remind you that this is not something I would recommend.
