What are you grateful for today?

This Thanksgiving, remember that gratitude is more than just a nice tradition, it’s a physiological superpower.

-Gratitude activates the vagus nerve, the key communicator between your brain and gut. This nerve stimulates digestion by promoting the release of digestive enzymes and regulating gut motility.
-It reduces cortisol (stress hormone) levels, which can otherwise impair proper digestion and nutrient absorption.
-A calm, grateful state shifts your body into ‘rest and digest’ mode, optimizing your digestive system for the feast ahead.

Gratitude helps your body function better.

So before enjoying your meal, take a moment to be truly thankful. Happy Thanksgiving! 🙏

Success doesn’t have to mean pushing your body to its limit.

For a lot of people, it’s having enough energy to get through the day, digesting your food without issues, waking up rested, and not feeling wired or depleted all the time.

Those aren’t small things. They’re signs your biology is working the way it’s supposed to.

And the basics matter more than people think.
Consistent whole foods instead of ultra processed ones.
Protein at each meal.
Stable blood sugar.
Regular movement.
A predictable sleep-wake rhythm.

None of that looks “ambitious” from the outside, but it’s what creates real metabolic stability and long term health.

You don’t need a complicated plan or a long list of hacks.
You need habits that actually support your physiology.

Sometimes the most meaningful change is choosing what keeps your system steady instead of what looks impressive.

Gratitude rewires your brain for resilience.

New research published in Frontiers in Psychology confirms what many ancient traditions and modern healing practices have long known: Gratitude has a profound impact on our mental, emotional, and even physical health. 🧘🏽

The study looked at over 1,200 adults and found that higher levels of gratitude were directly linked to greater psychological resilience, lower symptoms of anxiety and depression, and enhanced emotional regulation.

Here’s what’s happening under the hood:
- Gratitude activates regions of the brain tied to reward, empathy, and emotion regulation, including the medial prefrontal cortex and anterior cingulate cortex.
-These areas are key for buffering stress, recovering from setbacks, and staying grounded in uncertainty.

Every cell, every hormone, every pathway in your body is listening and responding in real time to your inputs.

That means you aren’t stuck with the way you feel!

Inflammation, brain fog, low energy, anxiety, mood issues - these aren’t random. They’re biological responses to the signals you’re sending your body.

When you change the inputs, your biology changes with it. Often in a matter of days.

Better food.
Better sleep.
Less stress.
More movement.
Cleaner environment.
A calmer nervous system.

These aren’t small things, they turn on your body’s innate healing systems.

If you want to kick start feeling better, I recommend starting with your food first. Here is some more information: drhyman.com/pages/10-day-detox

YOU have the power to change how you feel!

Did you know this?

The field of sociogenomics reveals how positive relationships influence gene expression, turning on genes that repair cells and turning off genes associated with inflammation and disease.

When you experience love and connection, your body releases hormones like oxytocin and endorphins, which calm the nervous system, lower cortisol levels (the stress hormone), and promote anti-inflammatory pathways.

These hormonal shifts signal your genes to activate cellular repair and longevity mechanisms. Even physical touch, like cuddling, can boost oxytocin and enhance your immune system.

On the flip side, chronic stress, isolation, or conflict triggers the expression of pro-inflammatory genes, accelerating aging and increasing your risk of chronic illness.

Love and connection are powerful for health and longevity.

Walking is one of the most underrated yet profoundly impactful things you can do for your health. Love this post by @ tjpower on IG🚶🏼

Here's what happens when you make walking a daily habit: Your cardiovascular system gets stronger, blood pressure drops, and circulation improves. Blood sugar stabilizes, especially after meals.

It also works wonders for your brain and mood. Walking lowers cortisol, boosts dopamine and endorphins, sharpens focus, sparks creativity, and even helps prevent cognitive decline.

And when you take your walk outside, the benefits multiply—lower stress, better sleep, and a deeper sense of connection to nature.

Aim for 30 minutes a day and mix it up - brisk walks for your heart, post-meal walks for blood sugar, or nature walks for stress relief. Which one will you do today?

Sitting for hours at a time doesn’t just affect your energy, it can seriously disrupt blood sugar control.

A recent study reveals that interrupting prolonged sitting with short bursts of movement can significantly improve glycemic control.

In the study, participants who performed 3 minutes of walking or 10 bodyweight squats every 45 minutes had better blood sugar regulation compared to those who stayed seated or even those who took a single 30-minute walk.

These frequent, targeted bursts of activity were shown to activate key muscle groups like the quadriceps and glutes, leading to better glucose management throughout the day.

This is proof that you don’t need to spend hours in the gym to support your metabolic health.

What you do in private always shows in public, and this is such good news.

Your diet shows in your energy. Your diet shows in your skin. Your diet shows in your confidence. Your diet shows in your results.

The whole foods you eat when no one's watching…the vegetables, the healthy fats, the clean proteins, they don't just disappear. They become the clarity you feel at 2pm instead of brain fog. They become the natural glow people notice. They become steady energy that lasts all day, not the crash-and-burn cycle of processed foods and sugar.

You can't fake real nourishment. Your body tells the truth. Feed it real food, and it shows. Skip the nutrients it needs, and that shows too.

You are what you cultivate when no one is watching. And every single meal is either building you up or breaking you down. Choose foods that serve you.
