Unless you have a rare specific medical condition, no. In fact, you may even find that you need to add more salt.

Interestingly enough, the recommendation that people limit their salt intake isn’t based on good science – much like the recommendation to limit saturated fats and to limit dietary cholesterol. New data and studies show that the most likely problem you’ll encounter from salt consumption is **too little salt**! There’s a lot more data about all of this on these several sites:

Above and beyond all of that, on a keto diet, you need a LOT of sodium. Failure to get sufficient salt will leave you with an electrolyte deficiency commonly referred to as “keto flu” – many people find they feel better supplementing above and beyond the sodium that Keto Chow has.

The really short version is: when your insulin is high it tells your kidneys that they need to hold on to a higher amount of salt than “normal” (sadly, high insulin is now the new “normal”), reducing your need for consuming salt. When your insulin is low, your kidneys do not go through the process of putting as much salt back into your blood (it takes it out regardless and has to put it back in which requires a lot of energy and work) – having higher levels of salt is actually a nice bit of rest for your kidneys when you are on an ultra-low carbohydrate diet.
