We would like to address the sustainability issue first by saying our creator, God, put you and all human babies into ketosis. And if those human babies are exclusively breastfed . . . they will stay in ketosis. It is our opinion that we should take note of that God given fundamental, nutritional cue and stay in ketosis from cradle to grave.
We are not advocating drinking human breast milk into adulthood. That would surely get you arrested (Lol). Rather just keep flowing with the original plan and keep eating and drinking high fat low carb for life!
