Warning: If you're not paying attention to this one hormone, there is a good chance it's causing you to burn muscle and build fat.
You read that right. There's one hormone that is the antithesis of all things health and fitness.
This one hormone has the power to undermine all your efforts in your workouts and your nutrition if you're not careful.
And here's the thing...
It's addictive...
It's deceptive...
And it's excellent at making you fatter, weaker, and less happy.
What hormone am I talking about?
I'm talking about cortisol.
You've probably heard of it. It's most commonly known as the "stress hormone." And that's a pretty good description.
But to truly understand why this stress hormone is so damaging to your health and fitness, you have to understand one critical thing first.
Hormones are the decision-makers in your body.
You can eat healthily, and your body can turn that food into muscle...
Or it can turn it into fat.
Your body makes that decision based on...
You guessed it, hormones.
Hormones are the 'decision makers' in your body.
Every time I hear someone say, "maybe it's my hormones," my first thought goes to their cortisol levels.
You can think of cortisol as the anti-testosterone.
You probably know that testosterone causes your body to burn fat and build muscle.
Simply put, testosterone is good, and cortisol is not. (This is a bit over-generalized, but you get the idea)
In fact, cortisol suppresses testosterone.
Put another way, cortisol suppresses your ability to burn fat and build muscle.
But it actually gets worse because cortisol also causes your body to build fat and burn muscle.
And to make matters even worse than that, according to Mayo Clinic, chronically elevated cortisol has been linked with a whole host of other problems as well.
Problems like:
And that's just scratching the surface.
By now, you're starting to see why cortisol is so damaging to your health and fitness goals.
Like I said before, cortisol makes you fatter, weaker, and less happy.
Stress.
That's it.
Every type of stress you can think of elevates cortisol.
A little stress is good for you, but chronically elevated stress levels really start to create a severe problem.
Remember, cortisol and causes you to build fat, muscle and be less happy in general.
You might be thinking, I need to eliminate all this stress in my life!
But let's be real, that's impossible. It's just not going to happen.
Plus, stress challenges you to grow and improve, so eliminating stress wouldn't be a great idea anyway.
The key is not to eliminate stress. It's to learn how to manage it effectively.
So here are a few simple things that I do and that I recommend to all my clients.
If you're like me and you like things to be more objective than subjective, then I have good news for you. You can get an extremely accurate measure of your body's stress using Heart Rate Variability (HRV).
HRV is what NASA uses to measure the stress on astronauts during training and in space. I'll save the details and science for a future blog.
For now, all you need to do is download the app Welltory, and it will give you all the information you need on how it works and how to use it.
Bottom Line
If you're putting in the work but find yourself in a continual plateau. There's a good chance the stressors in your life and lifestyle are causing your body to burn muscle and build fat instead of burn fat and build muscle.
You can use HRV to get a scientific measure and then adapt your day to your body's needs using any of the suggestions I gave above. A little bit of self-care to destress can go a long way toward making you happier and healthier.
Which is something you both need and deserve, right?
