322. improve your health
There is an entire industry devoted toward biohacking. Much of the time it serves as a distraction from focusing on the fundamentals of improving health. Rather than getting overwhelmed with all the opinions centered around hacking different aspects of your biology, just work on the basics. You could spend thousands of hours researching the best bio hacks and not come up with a better recommendation to improve your health than to eat whole, unprocessed foods, get outside in the sun, move a lot, sleep like you’re on vacation, surround yourself with loving relationships, and practice a bit of gratitude for everything you experience. You can put all the money you save on gadgets and expensive supplements into building a life that lets you live and capture health how you’re supposed to.
Carbs make you fat, change my mind…
Whenever anyone makes a claim, ALWAYS ask if it makes sense from an evolutionary perspective.
Most living things time their days with an internal clock that is synchronized by external cues (e.g., light and dark cycles). The sun is one constant that has been around forever, therefore our circadian rhythms developed to coincide with these light and dark cycles. This means that our biology is a product of the cyclical nature of the sun. This is evidenced by the light-sensitive receptors built into the cells of our eyes, skin, blood, and bones.
Who cares?
WELL, because our biology is indelibly linked to the sun, it would also be fair to reason that it plays a role in our health as well. And that’s all I really care about here.
Before industrialized society, we had always been at the whim of nature and the environment that the seasonal orbit and rotation of the sun provided; AKA seasons. We had always “feasted” in the summertime to endure the “famine” that always followed. Your body instinctually know that the long days of summer are going to be followed by the cold days of winter, and that means no food. Summertime means carbs are plentiful, as they literally grow on trees. Your body craves them so you can store fat to keep you alive for the impending winter where food is scarce.
Here’s how it works:
Long hours of light signal summertime
Summertime means carbohydrates are plentiful and should be eaten to excess
Eaten to excess causes accumulation of fat (and lowers freezing temperature of cellular structures) so that you can survive the winter
Fun fact: Types 2 Diabetes is a survival mechanism, but in a world where winter never comes it becomes a disease. The never-ending artificial light, coupled with chronic stress jacks up our hormonal cascade and registers as the long days of summer.
In the context of modernity, the effects of constant stress and artificial light adds up pretty quickly. We live in a fear-based 24-hour news cycle that creates an environment where we live under constant threat of war, rape, pandemic, getting fat, etc. This stress is heralded by cortisol which drives us to consume carbohydrates so we can attempt to reach homeostasis by balancing our cortisol with the insulin response. All the while, our circadian rhythmicity becomes disrupted because we’re staring at blue-lit screens all day, telling our brain that it’s daytime, signaling the long days of summer. And because summer comes before winter, our body’s “know” we need to eat so that we can have enough energy storage to survive the winter. BUT WINTER NEVER COMES because everything in our environment is signaling that it is summertime and we need to eat.
While living in endless summer may seem like a great thing in theory, it completely throws off our biology. There is no day without night, there is no ying without yang. Life is about balance, without it comes dis- ease.
