Always Tired After Breakfast? It’s Not You — It’s Blood Sugar, Cortisol, and Undereating
If you’re dragging by mid-morning, snapping by mid-afternoon, and wondering why your energy feels nonexistent even though you’re “eating healthy,” I want you to hear this clearly:

You’re not lazy.
You’re not broken.
And you definitely don’t need more willpower.

Most women I work with are underfed, overloaded, and running on fumes—trying to do it all with a smile and a metabolism that’s honestly confused as hell.

Let’s zoom out for a second and talk about what’s actually happening in your body.

Why You’re Exhausted After Breakfast (Even When You’re Eating “Healthy”)

A granola bar and iced coffee might feel like breakfast… but to your body, it often registers as stress.

Here’s why.

Blood Sugar Swings Trigger Cortisol

When you eat a low-protein, low-fiber breakfast (or skip breakfast altogether), your blood sugar spikes and crashes quickly. Your body responds by releasing cortisol, your primary stress hormone.

Research shows that:
  • Irregular blood sugar patterns increase cortisol production and worsen hormonal imbalances, especially in women
  • Cortisol dysregulation is linked to fatigue, mood swings, poor sleep, and increased cravings—particularly during the luteal phase of your cycle
So when that “healthy” breakfast leaves you shaky, tired, or ravenous an hour later, your body isn’t failing you. It’s protecting you.

What High Cortisol Actually Feels Like Day to Day

When blood sugar crashes and cortisol rises, it can look like:
⚠️ Sudden energy dips
⚠️ Intense cravings (especially for sugar or carbs)
⚠️ Brain fog and poor focus
⚠️ Irritability and mood swings
⚠️ Feeling wired but exhausted
⚠️ Disrupted sleep
⚠️ A cycle that feels unpredictable or harder than usual

And then - because we’ve been taught to - we blame ourselves.
“Maybe I just need more discipline.”
“Maybe I should eat less.”
“Maybe my body just doesn’t work right.”

But the truth is simpler (and kinder).

You probably just need breakfast.

And protein.

And fiber.

And honestly? Maybe a good cry too.

The Real Fix for Steady Energy (Without Another Rigid Food Plan)

This is the part most women are shocked by:

The solution isn’t cutting more food.

It isn’t tracking every bite.

And it definitely isn’t adding 47 new food rules to an already full mental load.

The fix is learning how to feed your body like it actually matters.

Because it does.

Start Here (Keep It Simple)

You don’t need to overhaul your entire diet today. Just do this:
✅ Add protein to your next meal
✅ Add fiber (fruit, veggies, seeds, or whole foods)
✅ Eat within a reasonable window after waking
✅ Notice how your energy shifts

That’s it. Let that be enough for today.

This one change alone can:
  • Stabilize blood sugar
  • Reduce cortisol output
  • Improve focus and mood
  • Support hormone balance
  • Help you feel like yourself again
If You’ve Been Googling These Questions… Read This

  • If you’ve ever searched:
  • “Why am I always tired after breakfast?”
  • “How to balance hormones with food”
  • “What to eat for steady energy”
  • “Why am I exhausted even though I eat healthy?”
Please know this: you’re not imagining it, and you’re not failing.

Your body is responding exactly how it was designed to respond when it’s underfed, overstimulated, and asked to keep pushing anyway.

This isn’t a willpower issue.

It’s a nourishment issue.

And the most powerful place to start doesn’t require perfection, restriction, or a total overhaul.

Start with one meal.

Add protein.

Add fiber.

Eat earlier than you think you “need” to.

Then notice how your energy shifts, how your focus steadies, how your mood softens just a bit.

That matters. And so do you.

You don’t need to do everything today.

You just need to give your body what it’s been quietly asking for.

One steady step at a time.

I am a bold, beautiful, sometimes timid, usually happy, essential oil, nutrition junkie. Although at 39 I feel as if I've had several careers over a lifetime (or at least sometimes when I look back at my resume that is what shines through). I've been a paralegal, an office manager, an administrative assistant, worked in commercial lending and have finally landed on nutrition.

My journey to nutrition started many years ago when my sister was diagnosed with celiac disease and food had to change for the family. From there, along my own health journey I’ve helped people not only figure out what to eat but how to do it so that it can work for them sustainably. For almost seven years I’ve been counseling people on their nutrition and weight loss journeys.

I am knowledgeable about what purpose food serves your body and I focus on finding sustainable options when it comes to food; this also led to my love of essential oils. I had the opportunity to attend a workshop where a registered dietitian spoke about using essential oils in her practice to help her patients. I was floored. I knew that #plantsheal but I didn't realize that others in the 'conventional' medical community thought that as well!! Learning that it was possible to incorporate these magical little bottles gave me a huge sense of hope.

As I learned more about these oils I was diagnosed with increased intestinal permeability or as many of us know it, leaky gut. Leaky gut has been around for quite awhile but many of us are just learning what this is or why this is even more common these days than ever before. Many issues can be related to leaky gut including autoimmune diseases. Receiving this diagnosis just led me down a path further to learn about nutrition and how to best serve my body and take care of myself.

Since birthing our sweet baby boy at home earlier this year I’ve been incredibly passionate about helping other women too who are pregnant and new mothers with their nutrition. Eating healthy for your pregnant body and your postpartum self is a game changer for both mother and baby.
