I went low carb as opposed to Keto. I also mixed in a bit of intermittent fasting. So far I am having greater success than my friends who are trying to do full Keto. I can also throw in a cheat day every week or two and not worry about it messing things up. I did start off going high fat; now I just do low fat if I can.
I would recommend anybody looking at this check out Dr. Jason Fung. He has this paid website, but all I did was watch his free stuff- both there and on Youtube.
