How to Improve Gut Health: 4 Keys to Lasting Wellness Through Functional Nutrition

The truth is, most medical doctors receive little to no training in nutrition, the microbiome, or the role of micronutrients — yet these are the foundations of true, lasting health. That’s where I come in.

I’m Meg Marie O’Rourke, a registered dietitian and functional nutritionist with over 20 years of experience. At Harmony with Food, I help people overcome stubborn issues like weight loss resistance, digestive discomfort, fatigue, and inflammation by addressing the root causes — starting with the gut.

If you’ve been dismissed by conventional medicine, told your labs are “normal,” or heard that food has nothing to do with it, you’re not alone. It’s time to take a proactive approach. We say, “Test, don’t guess.” Through functional nutrition and advanced gut microbiome testing, we identify what’s missing and help your body heal from within.

1. Heal Your Gut — Everything Starts in the Microbiome

Your gut is home to trillions of microorganisms — including bacteria, viruses, and fungi — that impact nearly every aspect of your wellness, from digestion and metabolism to your immune system and mood. This complex environment, known as the gut microbiome, needs balance and diversity to function well.

Even one round of antibiotics or years of a low-fiber, processed diet can disrupt this fragile ecosystem, leading to symptoms like bloating, constipation, brain fog, joint pain, and even weight gain.

Using functional testing, we assess your gut flora, detect imbalances, and guide you on how to improve gut health with personalized strategies — including targeted probiotics, prebiotics, and whole foods like vegetables, fruits, legumes, and grains.

2. Reduce Inflammation and Support the Immune System

Chronic inflammation is at the root of many conditions, including arthritis, depression, fatigue, and digestive disorders like inflammatory bowel disease. Standard blood work often misses key markers, but functional nutrition goes deeper.

We evaluate your oxidative stress levels, immune response, and nutrient absorption — then create a plan to reduce gut inflammation through healing foods, hydration, anti-inflammatory lifestyle practices, and supplements only when needed.

Improving your gut health naturally supports the immune system, helping your body fight off harmful pathogens and maintain microbial balance.

3. Overcome Weight Loss Resistance and Balance Blood Sugar

If you're eating clean, exercising regularly, and still not losing weight, your gut could be part of the problem. Poor digestion, imbalanced gut bacteria, or insulin resistance may be interfering with your metabolism.

Through functional nutrition, we use diet, micronutrient testing, and lifestyle changes to stabilize blood sugar, regulate hunger hormones, and reduce cravings — all without restrictive dieting.

High-fiber foods, whole grains, and plant-based nutrients can restore balance in the digestive tract and reduce the risk of metabolic disorders.

4. Restore Energy and Improve Mitochondrial Function

When your cells aren’t functioning properly, neither do you. Low energy, poor sleep, and persistent fatigue can all be signs that your gut and mitochondria need support.

We address nutrient deficiencies, encourage restorative sleep, manage stress, and support mitochondrial health through a combination of enzymes, vitamins, and healing foods. The result? Better digestion, sharper focus, and the energy to live your life to the fullest.

The Bigger Picture: Gut Health, Longevity, and Wellness

These four pillars — inflammation, blood sugar balance, mitochondrial function, and a healthy gut microbiome — are the foundation of long-term health. When your digestive system is working as it should, everything else improves: your mood, your metabolism, your immune function, and your overall sense of well-being.

At Harmony with Food, I don’t believe in endlessly adding more supplements. I believe in using the right ones — and getting most of your healing from whole foods, the right nutrients, and lifestyle strategies backed by science.
