Hmmmmmmmmm? I’m not dead yet but I figure if you think processed foods is healthy and nobody can figure out why everyone is dying of Alzheimer’s, diabetes, cancer and heart attacks etc. then maybe it is the quality of food being consumed not the ketogenic diet that is the long-term problem?
As far as sustainability is concerned, what brings death is not sustainable!
Eat drink and be merry for tomorrow we die? LITERALLY?
If all you were eating is unprocessed Whole Foods, you would be in ketosis (naturally, the way nature intended; spiking glucagon more often rather than insulin) without even trying, every piece of bread, pre-packaged laboratory grade chemically processed food and amount of refined sugars you consume takes years off the quality of your life at great speeds until it brings death and makes it that much harder to reverse diabetes or to get back to a healthy metabolic set point!
