Forget about the different 'anti-aging' theories. But I have some idea about the sort of lifestyle which keeps me *feeling* young at 60yrs.
Regardless of body weight:
EATING
1 Cut out seed oils
2 Cut out refined carbs and sugars
3 Reduce cereals/grains - pasta, bread,etc
4 Eat meat, seafood, eggs, some non-starchy fruit and veg
5 Don't drink calories (apart from animal blood) - just coffee, tea, water, red wine
6 Take megadose Vit C, (maybe Vit A & D3) as soon as an infection strikes
7 Cycle creatine (optional)
8 Calorie restriction – slight
9 No more than two meals a day
10 Time restricted feeding (18/6)
11 Intermittent Fasting - 24hrs once every 2/3 weeks
12 Intermittent ‘overeating’ - one or twice a week
PHYSICAL ACTIVITY
1 Resistance training – weights, circuits, and calisthenics
2 Intervals - short to long (anaerobic/lactic/aerobic)
3 Daily low-level activity
4 Occasional 'mega' challenges (once/twice a year)
5 Necessary aerobic base (ability to run a fast mile comfortably)
6 No chronic long distance running
7 (V.important) Retain the ability to generate/tolerate 'extremes' and high HR
9 Retain dynamic ability and fast movement capability 10 Retain muscle mass - combat dynapenia/sarcopenia i.e. keep strong esp. in lower limbs
10 SLEEP WELL
1 Get out in Nature
2 Get out of the City as much as possible
3 Get the Sun and fresh air
4 Keep in touch with good friends and family
5 Eliminate the sh*t from your life (things which harm you)
[Jensen’s Inequality & Convexity] - if there’s a nonlinear relationship between an input (calories) & an output (effect), if we look at the output for two different inputs, the average of the outputs is not equal to what we would find for the output from the average of the inputs
Is there's a 'sweetspot' for neurogenesis from Fasting?
This study was every other day fasting. Is there a better (whilst still adherable) way. Would there be benefits from 18/6 routine? IS there any additional effect from reduced total calories -if so, how much?
Aging decreases the ability to deal with variation - also the ability to generate variation; the two are intrinsically related. They are two sides of the same coin.
The fragility of the coffee cup is fixed whereas a 20yr old can cope with a jump...
...from 20ft, but at 70yrs cannot cope with a jump from 10ft. Fragility in increasing.
The aging body is like a badly run business, it can't adapt to environmental challenges, randomness, and variation.
The body no longer has the system to deal with it; more precisely the system is working within a reduced range, it has degraded.
This is why as one ages, to slow down the downward spiral, it is *essential* to keep working the 'tails', the extremes...
The single most important quality to retain is the ability to generate and tolerate extremes. If all you do is “take it easy”, eventually all you’ll be able to do is take it easy.
1 Hyper-palatable food
2 Too abundant - all the time
3 Don't need to exercise to get it
Obesity will never be resolved in this environment of abundance. Humans are hardwired to expend as little energy as possible to get food.
This is why exercise is hard for many people. Expending energy for no reason is the opposite of how we evolved. A fundamental driver of human activity has been taken out of the equation by human ingenuity
Ease of access to food allows us to eat as much as we like, whenever we like. We have no environmental constraints. We’ve got what we wished for – easy calories for less and less effort (supermarkets, apps, home deliveries,) and little danger in getting it.
