Your DNA Thinks You’re Still Running From Something

  Why mornings might matter more than we want them to

I saw a meme the other day that said the reason some of us don’t lose weight, even with exercise, is because our DNA still thinks we’re medieval peasants trying to survive famine and invaders. 
“Ah. Emergency. Better hold onto the fat.”

I laughed… and then felt mildly seen. Because a lot of modern health advice sounds like it’s built around this same idea: your body is not a rational, email-checking adult. It’s an ancient biological system constantly asking one question:

“Are we safe?”

And apparently, how we wake up each morning answers that question loud and clear.

The Cortisol Thing (Yes, That One)

Cortisol isn’t evil. It’s a hormone that helps you wake up, focus, and respond to stress. We’re actually supposed to get a natural bump in cortisol in the morning. It’s called the cortisol awakening response — your body’s built-in “boot-up” sequence.

The problem isn’t cortisol existing.
The problem is when your body thinks it’s in chronic threat mode.

That’s when stress hormones stay elevated, sleep suffers, blood sugar regulation gets messy, and yes — the body tends to hold onto visceral fat, the deeper abdominal fat that’s closely tied to metabolic risk.

So now we enter the “they say” part of the story. You know. The wellness people. The ones who seem to have a two-hour sunrise ritual and no children, no commute, and no inbox.

“They say” you should see the sun first thing

This actually has solid biology behind it.

Morning light hitting your eyes (no sunglasses, no window glare) tells your brain, via the retina and your master clock in the brain, “It’s daytime. We’re on schedule.”

That helps regulate:

• Your cortisol rhythm

• Melatonin timing at night

• Sleep quality

• Metabolic signaling

Translation: your body feels less like it’s free-falling through time and more like it knows what’s going on. That alone is a nervous system win.

“They say” don’t start the day with your phone

This one hurts.

I convince myself, while reaching for the phone, that if I scroll through my email, it will help me plan for the morning. Of course, then I look at dumb memes, (like the one I saw that inspired this blog post).

Blue-enriched light from screens isn’t the same as full-spectrum daylight. But the bigger issue might be what you’re looking at. Email. News. Notifications. Problems.

Before your feet hit the floor, your brain is already triaging micro-threats. That mental load isn’t imaginary — your nervous system responds as if you’ve entered “something needs to be handled” mode. So, you have double-whammied yourself with the dopamine, AND caused yourself a little anxiety.

That’s not calm, regulated physiology. That’s low-grade stress before coffee. Oh. And did I mention, “they say” don’t slam coffee?

“They say” don’t slam coffee immediately

Here’s a science word: adenosine.

Adenosine builds up in your brain while you’re awake and makes you feel sleepy. Caffeine blocks adenosine receptors, so you feel more alert. That’s useful.

But right when you wake up, your cortisol is already rising naturally. Adding caffeine on top of that can feel like stacking stimulation on stimulation. For some people, that combination feels more like “wired and stressed” than “calm and focused.”

Waiting a bit before coffee may let your natural wake-up system do its job first.

So, what to do instead of coffee?

“They say” drink water with a pinch of salt

Overnight, we lose water through breathing and sweat. Even mild dehydration can nudge the body toward a stress response.

A glass of water — and for some people, a little sodium or electrolytes — helps restore fluid balance and blood volume. When the body senses adequate hydration, it doesn’t have to work as hard to maintain blood pressure and circulation.

Less physiological strain = fewer reasons for the body to shout, “Something’s wrong!”

“They say” move — but gently

A short walk. Some mobility. A few bodyweight movements.

Not: “Surprise body, It’s 6 a.m.. We have a SPIN class with an overly enthusiastic leader and some really loud music.”

Low-intensity movement increases circulation, warms muscles, and signals,
“We’re alive. We’re functional. This is normal activity, not survival panic.”

Intensity has its place. But for a body just coming out of sleep, a softer start can feel more like regulation than threat.

And here’s where I roll my eyes… a little

Because this all assumes you have time to:

• Gaze at the horizon like a Renaissance painting

• Sip artisanal salted water

• Breathe deeply

• Commune with your circadian rhythm

Meanwhile, many of us are already mentally at 10 a.m. before our feet hit the floor.

I used to think, This is ridiculous. I have a life.

But then I tried it. Not every day. Just… more than zero.

And I noticed that it didn’t make my morning hard. Or unbearable. And I didn’t really even feel that stupid about trying “all of this”…(I mean, really, it’s like four tiny things).The same 10–15 minutes I used to spend scrolling email could have gone toward telling my body, “We’re okay. No one is chasing us.”

If that message helps my physiology feel safe enough to let go of some of its “protective” fat storage? I’m on board.

So about that meme…

No, I am not actually fleeing invading forces at dawn. No one is chasing me across a muddy field with a pitchfork.And yes, the meme is funny…but also, I don’t think there were a lot of medieval people running for their lives who were…overweight. But, C’mon. It’s funny.

But I might be  convincing my ancient, overprotective biology that the famine is over, the village is safe, and we don’t need to stockpile abdominal provisions like winter is coming.

Morning light. Water. A little movement. A slower start.

Maybe my body will get the message,  “We’re okay!”

And if my nervous system believes that — even a little — maybe my body doesn’t have to guard every ounce of “just in case” fat like it’s defending the homeland.

So no, I’m not running from the enemy.

I’m just sweetly telling my brain:

You can stand down now.
We’re safe.
Let go of the fat for goodness sake!
