Health and Fitness learnings for February: “If I had to limit my advice on healthier living to just one tip, it would be simply to learn how to breathe better”

These are various health and fitness notes I accumulated in February 2025.

Please do not treat them as concrete science or proven fact. I’m just as susceptible to misinformation and fake news and health bias as the next always-online nerd. Below is simply what interests me

Cider vinegar. It’s better for you than Ozempic. It’s cheaper than Ozempic and it reduces your appetite. Have a shot of #cidervinegar every day.

“If I had to limit my advice on healthier living to just one tip, it would be simply to learn how to breathe better,” wrote Andrew Weil, the famed doctor.

Study shows you can improve your mental health by training the suppression of unwanted thoughts aka “you can just get over things”.
Also words are like spells, be very careful while labelling yourself as “traumatized” or “depressed”, they start to become real.

Breathing way less delivered the benefits of high-altitude training at 6,500 feet, but it could be used at sea level, or anywhere.

Did you know, from the moment you’re born, you slowly glycate — you slowly cook. Like a chicken in the oven. And when you’re fully cooked, you die. On the inside, you’re actually browning.
If you look at the cartilage of a baby, it’s white. If you look at the cartilage of somebody who’s 100 years old, it’s brown. It’s been glycated.
Glycation is cooking and it’s aging.
Every time you have a glucose spike, it accelerates glycation. Glucose causes this cooking, this glycation, this aging.
The more glucose spikes you have, the faster you age. It shows on your skin as wrinkles, and it also ages your organs within.

And the way the body loses weight isn’t through profusely sweating or “burning it off.” We lose weight through exhaled breath. For every ten pounds of fat lost in our bodies, eight and a half pounds of it comes out through the lungs; most of it is carbon dioxide mixed with a bit of water vapor

The most anabolic supplement: Sprinting
200% Growth Hormone increase

@hubermanlab: If you have a lousy nights sleep you’re better off exercising than not. It offsets some of the negative effects. But don’t make it a habit to get lousy sleep and use exercise as a means to compensate. Get what you need to feel rested. Sleep tool kit below (zero cost no signup).

Orange peel itself has 3x the vitamin C of orange flesh: https://x.com/Thepaththrough/status/1890515478537273801

But you CAN maintain and build mitochondrial and lactic capacity. And you should.
How to?
Get really strong at 20+ rep sets and 2-5 minute bursts of endurance

@AdamMGrant
Surprisingly, ignoring worries can improve mental health.
Evidence: After practice blocking out fears, people were less anxious—and less depressed 3 months later—especially if they had high anxiety or PTSD.
Not all concerns demand attention. Some thoughts are worth dismissing.

High dose creatine good for countering sleep deprivation: https://x.com/ntfabiano/status/1888934331592196280?s=46

if you’re eating out and serious about avoiding seed oils while maximizing collagen intake – pho is the only real option.
a proper pho broth isn’t some watered down stock, it’s a 48 hour extraction process that pulls gelatin, glycine, proline, and trace minerals straight from the marrow.

Sprinting is the greatest anti-depressant in the world.
Studies show it boosts GABA (the neurotransmitter that literally shuts off anxiety and overthinking) up to 20%.
Not to mention the insane boost of IGF-1 growth hormone and testosterone that comes with regular practice too.
I have been doing 5 sets of 95% effort for 25metres every week since January 1st and have noticed a significant increase in big dick energy.
Seriously try sprinting. You will feel unstoppable.

When you contract muscles, they secrete proteins into bloodstream — “hope molecules” — that are anti-depressants, trauma recovery
A pharmacy in your muscles
Walking, dancing, weightlifting, swimming — anything that requires muscle contraction

@WillManidis I’ve met many more people who turned their lives around by walking around aimlessly for a couple hours a day than I’ve met people who have had their lives improved at all by professional therapy

A lot of the inflammation we experience is in processed foods, even ones that are very mildly processed. Preservatives, food dies, stabilizers, a lot of these things can even end up in organic foods these days

This meta analysis of over 300,00 people showed that sunscreen has NO effect on reducing skin cancer.

Omega-3 plus vitamin D “slows biological aging by 3-4 months over 3 years, particularly when combined with exercise.”
https://x.com/davidasinclair/status/1886637035793866928?s=46

However, the new analysis of 226,889 people from 17 different studies around the world has shown that the more you walk, the greater the health benefits. 
The risk of dying from any cause or from cardiovascular disease decreases significantly with every 500 to 1000 extra steps you walk. 
An increase of 1000 steps a day was associated with a 15% reduction in the risk of dying from any cause, and an increase of 500 steps a day was associated with a 7% reduction in dying from cardiovascular disease

Health and Fitness learnings for January: “90 minutes strength training a week are 4 years younger at the molecular level”

These are various health and fitness notes I accumulated in January 2025.

Please do not treat them as concrete science or proven fact. I’m just as susceptible to misinformation and fake news and health bias as the next always-online nerd. Below is simply what interests me

A new study suggests that every ten minutes of strength training you do a week increases your telomeres (the caps on the end of chromosomes, associated with longevity) by 6.7 base pairs.

People who do 90 minutes strength training a week are 4 years younger at the molecular level than those who do none.

However, following exercise training the transcriptional signature of aging was markedly reversed back to that of younger levels for most genes that were affected by both age and exercise.

Soleus is called “the 2nd heart” because it pumps blood back to the heart. It is also responsible for handling the most force of any other muscle.
// do more soleus raises

The researchers…found that even if people walked as many as 20,000 steps a day, the health benefits continued to increase. They have not found an upper limit yet
// crazy finding

For pullups — pull bar to you, not pull up to it

Eat less. Caloric restriction, fasting, and keeping your system light throughout the day seem to have real benefits. Being a little hungry most of the time might actually be good for you.

New Foundation exercises for lower back and core strength:

When you inhale, your heart rate speeds up. When you exhale, it slows down. Breathing in for a count of four and out for a count of eight for just a few minutes can start to calm your nervous system. Remember: when you feel agitated, lengthen your exhales.

Spermidine’s strong link to longevity: https://x.com/davidasinclair/status/1881519444939416016?s=46
Great sources of spermidine: natto, broccoli, mushrooms, cheese, legumes

The more we learn about circadian rhythm, the more we realize that the amount, duration, and type of light you get has all sorts of signaling and hormonal effects on your body. The Sun is not toxic, but most sunscreen is carcinogenic.

Health and Fitness learnings for November & December: “babies are 3d printed from food”

It’s frankly astonishing. One of the big breakthrough realizations for me was our similarity to plants. It would seem the positive charge of the air vs the negative charge of the earth is indeed exceptionally important for plants, and also important for humans as well. Grounding / earthing starts to make a lot more sense, as does our need for sunlight to remain healthy. Surface life appears to effectively be a capacitor charged by differences in charge potential and sunlight.

For those taking higher doses of vinegar, depressive symptoms dropped by an average of 42 percent, compared to just 18 percent in the control group who took smaller amounts in pill form.

Calley Means notes:
If walking were a pill it would be most powerful one
target is 7k steps / day — 70% reduction in all cause mortality
“muscle contraction is medicine”
It’s more about all day movement then short periods of exercise
10m walk after meal is most high impact habit
Soleus pushups = body activation, signaling to body that you’re moving and staying active
“babies are 3d printed from food” (!)

Girl finds a paper from the 90s that suggests lactose intolerance is a skill issue (not enough enzymes to digest it). Spams skimmed milk for two weeks and her lactose intolerance symptoms completely resolved.

Our findings suggest that wearing an eye mask during overnight sleep can improve episodic encoding and alertness the next day

Health and Fitness learnings for October: “Walking is an incredible glucose disposal signal”

Why raw carrots are so good for gut health:
-antibacterial against pathogens
-can bind excess bile, estrogen

One hour on plane with window open = 20 minutes in a tanning bed
Always close window shades when flying — reduces UV exposure since most airplane windows are not properly UV filtering

People who regularly used saunas reduced:
-Sudden cardiac death by 63%
-All-cause mortality by 40%
-Dementia by 66%
-Alzheimer’s disease by 65%

When drinking, eat lots of saturated fat — meats, cheese, eggs, coconut, butter, milk

NAD (750mg IV loading dose; not absorbed well orally) works almost inexplicably to help go from a sick state to a well state very quickly; loading dose with 1x per month maintenance dose “If I had to pick one thing for people, engaging in NAD would be it.” – Craig Koniver

You will always feel young so long as you can run sprints, regardless of your age. Best anti-aging exercise you can do

This isn’t just about canned soup—the same principle likely applies to other canned products, including soda, sparkling water, and other canned foods. It’s important to recognize that many aluminum cans are lined with plastics containing chemicals like BPA.

Deep stretch lifts are usually best:
-Full ROM
-5-10% more muscle growth

Brown rice could be bad for you due to high arsenic levels

When muscles contract, they secrete chemicals into the bloodstream. Among these chemicals are myokines, which have been referred to as “hope molecules”. These small proteins travel to the brain, cross the blood-brain barrier, and act as an antidepressant

Lose up to 2L of water on 10h flight — medical recommendation is 8oz water per hour of flight (one glass per hour)

Leg strength = longevity
* Weak legs = less mobility
* Bones are mineral factory for brain
* Older adult injury = falling, strong legs help

As a general principle, just avoid fried foods including french fries (acrylamide)

Cider vinegar: It’s better for you than Ozempic. It’s cheaper than Ozempic and it reduces your appetite. Have a shot of #cidervinegar every day.

Literature strongly suggests that speed and strength are the primary levers to longevity.

“Dips are upper body squats”

“Dead Hangs: I think these might have been the transformer, as I’ve only been doing them a few months. Get a pull-up bar and hang.”

It’s been interesting to follow the recent research on how one’s body adapts to exercise. It tends to return to a baseline of how much calories it burns. Thus, it means that your body is both 1) getting better at using the energy it has to burn, and 2) it’s routing the energy from well-intentioned systems that are actually harmful (like your immune system having too much energy and thus resulting in remaining chronically inflamed).
