I'm 254 days into switching to a ketogenic diet (complete with at home instant ketone finger prick blood tests using the very affordable keto mojo), and can't believe I waited so long. I was roughly surfing sugar highs for 39 years. Would highly recommend looking into this if you are a sugar/carb addict like I was.
My biggest problem with Keto is that is that one bad meal and your out. I found it was just such a pain in the as for other as much as it was for me. Every meal at someone elses house I had to make my specific nutritional requirements available to the host, which then puts them out.
Until you deplete the sugar stores. So like fast 24h and you're back in.
