Same here. I got lucky and discovered the Keto diet pretty much right before it took off into being the latest fad. So I got the benefit of missing all the “lose 100lbs in 10 minutes” nonsense and the commodified aspect of everyone selling you something.
And it worked fantastically and lead to complete lifestyle changes that have persisted and made a healthier me.
I still recommend it to people but always give heavy caveats to stay away from the fad part and go with the basics.
Or freetube, where it’s built in. Just gotta turn it on in settings.
