🧠 Why Protein Needs Fibre: The Gut-Smart Combo Backed by Science

Feeling bloated after a protein shake? You’re not alone.

Protein is essential — for muscle, metabolism, and keeping you full.
But when it’s not paired with enough fibre, it can do more harm than good.

At Yeppoonie Smoothie, we combine protein with real-food fibre in every blend — and here’s why that matters.

1. 💥 Too Much Protein, Not Enough Fibre = Digestive Chaos

If you’ve ever felt bloated, backed up, or heavy after a high-protein meal or shake, it’s not in your head.

📖 A clinical review in the American Journal of Clinical Nutrition found that high-protein, low-fibre diets are commonly linked to constipation and sluggish digestion — especially in athletes or those trying to lose weight.

“Protein-heavy diets lacking fibre can impair regular bowel function.”
— Lambert et al., 2004

2. 🧬 Fibre + Protein = Appetite Control & Hormonal Support

When fibre and protein are consumed together, they work as a team to keep you full and balanced.

📖 A 2016 study in Nutrients showed that this combo stimulates GLP-1 and PYY, your body’s natural fullness hormones — the same ones targeted by GLP-1 medications like Ozempic.

“Protein and fibre together stimulate satiety hormones more effectively than either alone.”
— Solah et al., 2016

3. 🌿 Fibre Supports Hormone Balance (Especially in Women)

For those navigating hormone shifts — like perimenopause or stubborn belly fat — fibre plays a powerful behind-the-scenes role.

📖 A landmark study in Journal of the National Cancer Institute found that fibre helps eliminate excess estrogen through digestion, improving hormonal balance.

“Fibre enhances fecal excretion of estrogen, supporting hormone regulation.”
— Goldin et al., 1982

4. 🔄 Fibre Slows Digestion and Prevents Blood Sugar Spikes

Not all fullness is equal. Protein fills you — but fibre slows it down, giving you stable energy without the crash.

📖 A review in Nutrition Reviews concluded that soluble fibre slows digestion, reduces cravings, and improves energy regulation.

“Fibre increases satiety and helps regulate glucose absorption.”
— Clark & Slavin, 2013
