Manuel is right! I would follow bulletproof coffee. Lots of people swear by it. You can check out the website at:
If you're interested in stuff like this then I would definitely look up the term "biohacking". I read various articles/listen to podcasts on health, quantified self, etc. If you really like science and enjoy learning about how your body works and why it does what it does, you should definitely check it out!
Take everything you read, see, or hear with a skeptic's viewpoint and make sure you do your research before you try anything, but I honestly think people who really want to improve their health will like it.
Btw if anyone wants some good resources I've found on this kind of stuff feel free to reach out. :)
