This episode made me think about permaculture and how it could relate to the ketogenic diet. Permaculture principles would include raising livestock in a way that is renewing to the soil, increasing nutrients that improve the quality of what the animals graze on. The people have healthier meat, milk, eggs etc. to eat. I personally would be interested in a meeting of the minds between you dudes and Geoff Lawton there in Australia, an international permaculture expert. I think he would appreciate how eating keto tends to reduce waste, and the emphasis on nutrient-rich food sources. He would be interested in how it is a sustainable way of eating.
