My heart rate has dropped after being on keto - what can I do?

The pulse rate, if it's low, really means that you need to increase your sodium especially in keto, as well as intermittent fasting. That's one thing that people don't consume enough of is sea salt. So start getting more salt in your body and see if your pulse rate doesn't come up. The other thing to look at is your adrenals. How are they? Are there other factors, stress-wise, that type of thing? But I would really recommend going with the sea salt.
