• Move calmly through the ketosis milestone, the twenty-four to thirty-six hour window where the body shifts from burning sugar to burning fat, so the first signal you feel becomes your first victory.
• Choose and prepare the right water, and understand why Dr. Group fasts on distilled water alone and drinks half his body weight in ounces of it every day, so every glass you drink is supporting the rest of the fast.
• Prepare your body and your surroundings in the two or three days beforehand, so your fast can put everything it has into healing.
• Break a fast the right way, using the quarter-of-the-length rule and the gentle return to living food, so the regeneration continues for months after the fast itself has ended.

He will also show you the shorter practices, the ones that fit an ordinary week. The evening meal set aside. The single fruit in the morning. The half-meal. One quiet day a month. Gandhi fasted one day a week and nine to twelve days a year, and at sixty-four, on the tenth day of a fast, his physicians described him as being as healthy as a man of forty.

This is what Dr. Group, DC means by simplicity. You take one practice, live it until it feels natural, and then reach for the next. That is the whole method, and every part of it is free.

And here is what he has watched happen for thirty years. When the load lifts, energy comes back. And underneath the energy, capacity comes back. The attention that has been going into getting through the day comes free, and it goes somewhere. That is the part worth staying for.

It is also how aging well actually happens. Not in one decision, but in a practice kept for years, with dignity, and with the body treated as the gift it is.
