I have trouble with "moderation." I like to take it over the top here and there. Occasional gluttony in moderation.
I like getting my stuff from lectures from people that are top in their fields, who are quoting studies. Then, I often check out the studies.
Plenty of rest. Exercises, aerobic, just breathing hard once or twice a day, strength workout three plus per week. I try to get up and do movement every hour or so, I've failed this over and over. I keep at these better habits and I'm steadily adopting them. I got rid of my couch to live more Japanese on the floor. It makes a big difference.
The food and the fasting, I'm doing great. Whole plant based, fermented foods, fresh as can be, from the best of soils, cooked lightly, as close as live and living as I can, and as great of a daily/weekly variety as I can find, herbs and all. I eat lots of fun, new diverse foods and it is very fun, enjoyable, interesting. I have mastered the Devil's draw of pizza and ice cream. I am in a habit of staggering a very thoughtful regimen of supplements to augment and make up for age related needs. This is pretty simple and tons of research, biological and statistical support it. I feel the difference and observe changes. When I do manage to keep my moderate exercise disciplines and nutritional food together, the combination amazes me.
I fast three or four times a year for around five days. Lots of research. It isn't such an imposition when I feel the dramatic benefits.
Sauna, sweats, are difficult to keep at. The social and musical aspects have kept me more regular. It bores me otherwise. Three days per week at three rounds at 170F to 180F, fifteen to twenty minutes each are that goal, but I do manage at least one longer period each week. This is primarily from a the Finnish long term studies. The biology is well documented. A simpler life supports simple regimens.
Naked active in nature, often. It's worth the effort, every time.
I'm retired. My new job is my health. What better task for these years, but unlearn bad habits, improve good habits and extend my life of quality. I can see where a lack of change will give me the results that i see it doing to people's health all around me. We shall reap what we sow. Friends are looking and moving inflamed with pain, overweight in the same common ways, over doing and dying. I'm getting younger, as in better and better health, feeling it.
