How Your Microbiome Shapes Cravings & Energy
When Maria (not her real name) was first diagnosed with prediabetes, she thought it was all about sugar. Eat less of it, walk more, and things would be fine. But soon she noticed something else no one had warned her about: her digestion was off. Bloating, discomfort, unpredictable cravings; it felt like her body was fighting her at every step.
I’ve seen many clients with prediabetes share this exact frustration — they expected to manage blood sugar, but gut issues like bloating or cravings threw them off track. Once we started simple gut-supportive steps, their energy improved in just a few weeks.
“Could this be my gut?” she wondered. She’d seen influencers online raving about kombucha and probiotic gummies, but the advice seemed confusing and expensive.
If you’ve ever felt that same overwhelm, you’re not alone. Gut health has become a buzzword, but it’s also one of the most important and overlooked foundations for blood sugar balance.
Why Gut Health Matters for Prediabetes
Recent research from the American Diabetes Association (2022) highlights how gut imbalances can reduce insulin sensitivity, making blood sugar harder to manage.
Your gut isn’t just where food gets digested. It’s home to trillions of bacteria (your gut microbiome) that interact with nearly every system in your body. For those with prediabetes, the microbiome plays a direct role in:
- Blood sugar regulation: Certain gut bacteria influence how sensitive your cells are to insulin.
- Cravings: An imbalanced gut often “asks” for fast fuel — hello, sugar cravings.
- Nutrient absorption: If your gut isn’t working properly, your body struggles to use the vitamins and minerals it needs for stable energy.
Researchers have even found that people with insulin resistance often show a different gut microbiome composition compared to those without it.
While we’re still learning how deep the connection goes, the evidence is clear: taking care of your gut supports your blood sugar.
Busting the Myths
With so much noise online, it’s easy to get lost. Let’s clear up a few myths:
- ❌ You don’t need a cleanse or detox tea.
- ❌ You don’t need to spend hundreds on supplements.
- ❌ You don’t need to eliminate all carbs.
Now I can confirm that Gut health thrives on simple, consistent habits. Doesn’t have to be complicated or expensive.
Prebiotics vs. Probiotics (Explained Simply)
There are lots of scientific explanations and terms out there to explain this, but I will break it down in simple terms. Think of your gut like a garden:
- Probiotics = the good bugs (the plants in your garden).
- Prebiotics = the food that helps them grow (the fertilizer).
Probiotic foods:
- Yogurt (look for “live and active cultures”)
- Kefir
- Sauerkraut & kimchi
- Miso
Prebiotic foods:
- Onions
- Garlic
- Bananas
- Asparagus
- Oats
When you combine the two, your gut bacteria flourish and so does your blood sugar stability.
What Happens When Gut Balance Is Disrupted?
Sometimes, despite our best efforts, gut health gets disrupted.
- Antibiotics: While lifesaving, they wipe out not only the “bad” bacteria but also the beneficial ones that support digestion and blood sugar regulation. This can leave your gut like a garden after a storm — stripped and needing to be replanted.
- IBS (Irritable Bowel Syndrome): Whether IBS-C (constipation) or IBS-D (diarrhea), both often go hand in hand with gut imbalances. Symptoms can flare when the microbiome is out of balance.
- Stress, poor sleep, and restrictive diets: These also shift gut bacteria in ways that increase cravings and worsen blood sugar control.
A Functional Medicine Approach 👉 Functional medicine often uses a framework called the “4R Protocol” to bring balance back:
- Remove triggers (like processed foods, excessive sugar, or food intolerances).
- Replace digestive support (such as enzymes or stomach acid support, if needed).
- Reinoculate with probiotics and prebiotics.
- Repair the gut lining with nutrients like zinc, glutamine, and omega-3s.
You don’t have to go “all in” on a strict protocol, but the takeaway is this: if you’ve had repeated antibiotics, digestive struggles, or ongoing IBS, your gut may need extra support and it’s always wise to work with a healthcare professional to personalize your plan.
Medications and Gut Health: Metformin & GLP-1s
If you’re on metformin or GLP-1 medications , you may already be experiencing the gut-related side effects: bloating, gas, diarrhea, constipation, or nausea.
Here’s how to support your gut naturally while on these medications that are typically used to manage diabetes, prediabetes and in some cases PCOS:
- Start small with fiber → Gradually add beans, veggies, or whole grains. Jumping in too quickly can make symptoms worse.
- Pair meds with food (if your doctor allows) → Helps reduce nausea.
- Eat smaller, frequent meals → Less stress on digestion.
- Hydrate often → Keeps things moving and eases constipation.
- Choose probiotic-rich foods → Yogurt, kefir, kimchi are gentle options.
👉 For those times when food isn’t enough, I recommend choosing high-quality supplements from trusted sources. I use Fullscript for professional-grade options that I trust with my own clients.
How to Support Gut Health Naturally
Beyond meds, everyone can benefit from these everyday gut-friendly habits:
- Load your plate with fiber: Half veggies, a quarter lean protein, a quarter high-fiber carbs.
- Move after meals: Even a 10-minute walk lowers post-meal glucose and aids digestion.
- Stress less, sleep more: Poor sleep and chronic stress disrupt gut bacteria and blood sugar alike.
It doesn’t have to be complicated. In fact, it’s often the smallest shifts that create the biggest changes.
From Gut to Plate
Here’s the good news: taking care of your gut doesn’t mean buying into the latest trends. It often looks like eating real food, getting movement, and supporting your body in small but meaningful ways.
And when your gut feels better, your energy stabilizes, your cravings calm down, and managing prediabetes feels more doable.
