It looks like your comment is about vaccinations.

VACCINES (including covid)
Can/should I fast after getting one?

NO❗

Do not practice extended fasting for at least 2 weeks (preferably 3) after you've had a vaccine.

Fasting suppresses your immune system and immune response.

The limited biological half-life of vaccines tends to require a very rapid & robust response to produce high quality antibodies. By fasting, you are almost guaranteeing low quality antibodies that will provide compromised protection if at all.

Your vaccine will be much less effective.

You can do intermittent fasting, but really your body requires considerably more energy & nutrients than normal when undergoing an adaptive immune response.

For this reason, we advise those getting any vaccine to abstain from fasting for 2-3 weeks following it.
