You are not alone.  I know of other people who have problems with a diet
that derives more than 40 or 45% of calories from fat.  It doesn't matter
the source---fat from grassfed meat, oily fish, olive oil, flax oil, nuts,
seeds.  I've met others who experienced the same symptoms you describe,
progresing to severe liver and gall bladder distress (signs of fat
indigestion, nausea, bloating and tenderness around the liver, oily stools,
a feeling of malaise, pain, etc.).  It may be that when you go too low in
carbs and too high in fat and/or protein (people appear to differ in their
tolerance to fats, protein, and carbs), the liver may have difficulty
metabolizing them, converting protein into glucose, dealing with the by
products of excess protein, etc.
