I really like this Dr. Phinney quote. It emphasizes the long term overview:
“Health is defined by where you will be 1 year or 1 decade from now, not where you will be in 1 week or 1 month.” Stephen Phinney, MD
For me this involves the art of suspending disbelief and having lots of self-compassion, meaningful daily practices, contented intermittent fasting, feasting on savory fat/seasalt/spices/veggies/protein, and the n=1 adventures of joyful self-experimentation.
I have found it very helpful to suspend time and linear thinking whenever I can (as technically speaking, timelessness is the only reality that has been mathematically proven as inifinity, etc.) for life cycle processes and for arduous meditation training and certain kinds of meditative yoga & martial arts. To that end, ever since I learned various traditional healing insights, for chronic issues I give myself 4 seasons with new healing protocols before coming to final conclusions on efficacy.
It helps me to never count calories and to rarely if ever weigh myself, and to only measure myself every month or two. I mostly focus on delicious feasting and effortless fully fat-adapted (am 9 months in to keto now) 18-22 hour fasting a couple times a week, knowing that “now” is all I really have, and the “now” of today becomes the past of tomorrow, etc.
I really like some of historical perspectives on longevity & rejuvenation that keto researcher Christi Vlad Zot puts forth in his book Periodic Fasting: Repair your DNA, Grow Younger, and Learn to Appreciate your Food where he studies the fascinating lives of long-lived historical guys Upton Sinclair and Luigi Cornaro. Throughout ancient civilization history (which is just a brief time of just the last 8K years or so compared to 90% of human history which was aboriginal gatherer/hunter) there have been rejuvenation practices and longevity secrets in various places east and west, north and south. Common to judeo-christian cultures, in the Hebrew Bible there was Methuselah, who lived 969 years, longer than anyone else recorded in written history - though that’s not saying much as most of human history is oral history. His father was Enoch, of whom it is said passed at 365 years. And in Taoism and many eastern meditation and earth-based traditions, ‘immortality’ of unified outlook and self-cultivation/rejuvenation was woven into many beliefs - for a different perspective on chronological age and a life well lived.
Anyhoo, LCHF/keto/IF helps me live my best life regardless of outcome, more than ever!
