3 Signs You Need to Rebalance Your Gut – and 3 Simple Fixes

Dr. Shawn Talbott (Ph.D., CNS, LDN, FACSM, FACN, FAIS) has gone from triathlon struggler to gut-brain guru! With a Ph.D. in Nutritional Biochemistry, he's on a mission to boost everyday human performance through the power of natural solutions and the gut-brain axis.

Your gut is more than a dumb tube for digesting your food – it’s mission control for your mood, immunity, and even how much energy you have during the day. 

When the gut microbiome (the trillions of bacteria living in your intestines) falls out of balance, your whole system feels the effects.

Here are three signs your gut is crying out for a reset – along with 3 science-backed ways to bring it back into balance.

1. Digestive Distress Becomes the Norm

• Sign: Bloating, constipation, diarrhea, or inconsistent digestion are often the body’s first SOS signals.

• Solution: Fiber first.

Fiber feeds beneficial gut bacteria, helps regulate bowel movements, and creates short-chain fatty acids that calm inflammation.

• Aim for 30+ grams per day from sources like oats, beans, chia seeds, and vegetables.

• Bonus: Diverse fibers = diverse microbes, which equals better gut resilience.

2. Your Mood and Energy Swing Like a Yo-Yo

• Sign: Feeling irritable, anxious, low-energy, or experiencing brain fog.

• Solution: Fermented foods.

These are rich in “postbiotics” like oligosaccharides, SCFAs, peptides, and polyphenol metabolites that protect your gut microbiome and stabilize your gut-brain axis.

• Try a daily dose of kefir, sauerkraut, kimchi, miso, or unsweetened yogurt.

• Research shows that regular fermented food intake can reduce inflammatory markers and improve emotional well-being.

3. You Get Sick More Often Than You’d Like

• Sign: Frequent colds, allergies, or a sluggish immune system.

• Solution: Flavonoids.

These plant compounds act as microbial “trainers” – encouraging beneficial bacteria while suppressing the troublemakers.

• Found in berries, citrus, green tea, onions, and dark chocolate.

• Think of flavonoids as both antioxidants and prebiotic helpers for your microbiome and the important gut lining (aka prevents “leaky gut”).

The Gut Reset in Action

Fiber = foundation ? feeds microbes.

Fermented foods = reinforcements ? adds beneficial molecules.

Flavonoids = protectors ? shield against oxidative stress and bolsters the gut lining

Together, they create a gut ecosystem that supports digestion, mood, immunity, and whole-body vitality.
