The 80/20 principle and eating

I like to experiment with my dietary habits to see if can improve my health and well being. I like it even more when I find advice that is concise and looks plausible from a scientific perspective.  I've recently come across a couple of bits which I thought I'd log here:

First up, there's the wonderfully concise Michael Pollan:

Eat food. Not too much. Mostly plants.

and more recently, Rhonda Patrick on the Tim Ferris podcast:

• Cut out refined sugar
• Intermittent fasting
• Eat more vegetables
• Take Vitamin D (if needed)

PS. I am not a doctor, and don't pretend to be one. Do your own research, speak to your doctor etc.
