Glucose 101: Why Blood Sugar Spikes May Be Harming You—And How to Fix Them
You’ve probably heard the word “glucose” tossed around in health podcasts or wellness articles.
Maybe, like many of us, you’ve associated it with something boring or only relevant if you have diabetes.
But best-selling author and biochemist Jessie Inchauspé, known to millions as The Glucose Goddess, is changing that narrative.
Her insights into blood sugar and how it affects everything from mood to metabolism have made glucose one of the most talked-about health topics of the year.
In this article, we’ll walk you through exactly what glucose is, how blood sugar spikes mess with your energy, cravings, hormones, skin, and long-term health—and most importantly, the science-backed hacks that can help you balance it all without giving up the foods you love.

Why You Should Care About Glucose (Even If You’re Not Diabetic)
Glucose is your body’s preferred source of energy.
Each cell in your body uses it to function, including your brain, muscles, and organs.
But here’s the catch: when too much glucose floods your system too quickly—what Inchauspé calls a “glucose spike”—it stresses your body.
“The more glucose spikes you have, the faster you die,” Inchauspé says bluntly in a recent interview.
While it sounds dramatic, the science supports her statement. Glucose spikes have been linked to:
- Cravings and constant hunger
- Energy crashes and brain fog
- Acne, inflammation, and premature aging
- Hormonal imbalances, infertility, and PCOS
- Increased risk for Alzheimer’s, type 2 diabetes, and cancer
And here’s the kicker: you don’t need to be diabetic to suffer from them.
Studies show that even people with healthy fasting glucose may experience dramatic spikes throughout the day depending on what and how they eat.
So, What Is Glucose Exactly?
Glucose is a type of sugar found in many of the foods we eat—especially carbohydrates like bread, rice, pasta, sweets, and even fruit.
Once digested, it enters the bloodstream and is used by the body’s cells for energy.
But when there’s too much of it at once, three major things happen:
1. Your mitochondria get overwhelmed
Mitochondria are the energy-producing engines in your cells.
When flooded with glucose, they can’t keep up and start producing stress molecules that contribute to fatigue and chronic inflammation.
2. You trigger glycation—the process that ages you faster
Excess glucose sticks to proteins in your body and damages them, a process called glycation.
On the outside, this shows up as wrinkles.
On the inside, it leads to stiff arteries, joint pain, and deteriorating organs.
3. Your body pumps out insulin to remove the glucose
Insulin is the hormone responsible for shuttling excess glucose out of your blood and into your cells—for storage in your liver, muscles, and fat.
Frequent spikes require frequent insulin releases, which over time can lead to insulin resistance, weight gain, and type 2 diabetes.
The Symptoms of Blood Sugar Spikes
Unless you’re tracking your glucose with a continuous glucose monitor (CGM), you might not realize your blood sugar is spiking dramatically.
But your body leaves clues—and they show up every day in subtle (and not-so-subtle) ways.
Short-Term Symptoms
- Sweet cravings, especially after meals
- Energy dips in the afternoons
- Brain fog and forgetfulness
- Acne, PMS, bloating
- Needing coffee or sugar to “feel awake”
Long-Term Consequences
- Insulin resistance and type 2 diabetes
- Weight gain and stubborn belly fat
- Hormonal imbalances and PCOS
- Dementia, heart disease, and cancer
- Accelerated skin aging and inflammation
“If you’re feeling unwell, tired all the time, or struggling with chronic health issues, glucose is the first thing to investigate,” says Inchauspé.
10 Glucose Hacks that Can Change Your Life
1. Eat your food in the right order
Always start with fiber-rich veggies, then eat your proteins and fats, and save starches and sugars for last.
Why? Fibers from veggies create a viscous mesh in your intestines that slows down how quickly glucose enters your bloodstream.
2. Never eat carbs naked
If you’re going to eat bread, pasta, or something sweet, pair it with protein, fat, or fiber.
This minimizes the glucose spike and its aftermath.
3. Go for savory over sweet at breakfast
Sweet breakfasts like cereal, juice, muffins, and granola kickstart a glucose roller coaster that lasts all day.
Switch to eggs, avocado toast, or Greek yogurt with chia seeds for sustained energy and fewer cravings.
4. Move after you eat
Even a 10-minute walk after a meal can cut glucose spikes significantly.
Alternatively, do squats or calf raises at your desk. Contracting muscles pull glucose from your blood like a sponge.
5. Use vinegar before meals
One tablespoon of vinegar in a tall glass of water before eating can reduce glucose spikes by up to 30%.
Apple cider vinegar or white wine vinegar both work well.
6. Eat whole fruit instead of juice
Fruit juice—yes, even fresh pressed—is essentially liquid sugar.
Whole fruit contains fiber that slows down glucose absorption, making them way healthier.
7. Don’t fear fat
Healthy fats like olive oil, nuts, seeds, and avocado help slow down the digestion of carbs, blunting spikes.
Contrary to outdated advice, these fats don’t make you fat—glucose spikes do.
8. Be mindful of caffeine on an empty stomach
Drinking coffee first thing can increase cortisol, which worsens glucose control and anxiety.
Have a savory breakfast first, then enjoy your coffee.
9. Save dessert for after meals—not mid-afternoon
It’s not about giving up your treats.
It’s about timing them when your bloodstream is already buffered by fiber, fat, and protein so the glucose hits slower.
10. Don’t count calories—balance glucose
Two meals with the same calories can have massively different effects on your metabolism based on how they regulate blood sugar.
Calorie counting is outdated. Focus on food quality and glucose impact instead.
How Jessie’s Personal Health Journey Led Her Here
This wasn’t just about biochemistry for Jessie Inchauspé—it was survival.
After a traumatic spinal injury at age 19 and a painful recovery, she began experiencing debilitating mental health symptoms including panic, depersonalization, and extreme fatigue.
Eventually, she discovered a key insight: her mental health crises intensified whenever her blood sugar spiked.
“That was my eureka moment,” she explains. “I could see the connection between a glucose spike and my mental state. It gave me hope.”
The Most Powerful Tool You’re Not Using—Yet
Balancing your glucose doesn’t mean cutting out carbs or never touching dessert again.
It means learning how to eat with simple science on your side, so your body works with you, not against you.
You’ll feel better, think clearer, and age slower. And you can still have the cookie.
“Learn the glucose hacks,” says Inchauspé, “then eat everything you love.”
