Most people will need to supplement electrolytes when first going low-carb. You cut the carbs, dump your fluids, you're out of potassium and magnesium and your blood pressure drops. Definitely salt your food heavily for now, but eventually look into adding sweet potatoes, avocadoes or other good sources of potassium on a regular basis. I supplement magnesium from time to time if I'm not drinking much broth, etc., to make sure I'm getting enough.
Steak, eggs, potatoes - fruits, nuts, berries and forage. Coconut milk and potent herbs and spices. Tea instead of coffee now and teeny amounts of kelp daily. Let's see how this does! Not really had dairy much, and gut seems better for it.
