Keto vs not keto...

I think there's always the potential for people to take things 'too far' with guidelines that are completely black and white but yeah. It's not rocket science. There's a reason some cultures/countries have longer lives than others. Healthcare is part of it but there's no denying the role of food and the relationship people have to it. The U.S. is way down the list of life expectancy and moving in the wrong direction.

Your fish need keto
