I've heard something about the benefits of fasting previously, but this was very comprehensive post and gave loads of new info. If you know anything about the disadvantages that fasting has when it comes to e.g. metabolism (the changes in energy levels etc.), it would be great to read about them!I agree with @annemariemay -I appreciate the informativeness of this post too.
Fun fact: my friend has tried fasting multiple times and I think his motto is "Cucumber and water makes you feel fucking great!" (He also drinks large amounts of Pepsi Max when his fasting, so I don't trust his expertise on this matter…)
