Introduction
I’ve had a few questions recently about the carnivore diet — and I’ve also seen several patients in clinic who are following it. So here’s my take on it: the good points and the drawbacks.

Q&A
Why do people feel better on the carnivore diet?
Many people report less bloating and cramping when they remove fibre. Plant fibre can irritate an inflamed or sensitive gut lining. A meat-only diet is simple — fewer variables, fewer reactions — so symptoms often calm down quickly.
What are the main drawbacks?
When fibre disappears, gut bacteria that rely on it lose their food supply. This can shift the microbiome within days. High-meat diets also increase bile, favouring bile-tolerant bacteria and reducing butyrate-producing species that support the gut lining.
Is it dangerous or unsafe?
Not necessarily. Some people tolerate it well short-term. But long-term, reduced intake of vitamin C, folate, and antioxidants can become an issue, and the long-term microbiome impact remains under study.
What do you recommend instead?
Introduce the diet gradually. Listen to your symptoms. Consider checking nutrient levels and microbiome if you stay on it. The goal is not total elimination forever — but finding a sustainable balance.
