Are there any specific dietary changes in biohacking?

Hello all. To cut a long story short, I've been struggling with extra weight for a while, and my neighbour told me I should try biohacking. I don't really know much about it, but she gave me some blog articles to read through.

Nevertheless, I wanted to ask if there is like a biohacking food list of things I should avoid, if that makes sense? Do you perhaps know where I could find some biohacking recipes I could try? Thanks
