– How can I avoid the
keto flu when beginning a low carb high fat lifestyle? – For most people the key
to this is just making sure that they are getting enough sodium. So when you start a ketogenic lifestyle you actually diurese,
which means you get rid of excess water. Because when you’re eating
a lot of carbohydrates, believe it or not, our
kidneys hold on to sodium. And when we decrease those carbohydrates, our kidneys will excrete excess sodium. And that can actually cause people to become sodium depleted. And so it’s important for
people to increase the sodium, especially early on, in a ketogenic diet to ensure that this does not happen. Because as you excrete too much sodium, it can cause you to feel tired, it can even give some people headaches. And so again, increasing the
sodium intake is important. Now if you’re someone with a
history of high blood pressure, this is something that you want to talk to your physician about. Of course the goal with a ketogenic diet for many people who come and
start with high blood pressure is to be able to improve
that blood pressure enough to be able to get off
blood pressure medications, and that happens very frequently. Many trials have shown this, including our large clinical trial. But again, physician supervision, and making sure that you’re
getting enough sodium intake especially early on. – And hydration, so fluids to go along
– Hydration, that’s right. – with the sodium, that balance.
– Fluid to go along.
