9 Evidence-Based Ways to Improve Your Gut Microbiome

Your gut microbiome controls your metabolism, immune system, inflammation, mood, brain health, insulin sensitivity, and long-term disease risk — and in this video, Dr Alex explains 9 evidence-based ways to improve gut health, increase microbial diversity, and fix gut dysbiosis naturally, without supplements or extreme diets.

Most people think gut health is just about digestion. It isn’t.
Your gut bacteria quietly influence energy levels, blood sugar control, weight gain, cravings, inflammation, mental clarity, immune resilience, sleep quality, and ageing — often years before disease appears.

In this video, I break down exactly how to improve your gut microbiome using science-backed habits that actually work in the real world. No fads. No detoxes. No probiotics you don’t need. Just practical, evidence-based strategies that support microbial diversity, short-chain fatty acid production, and long-term metabolic health.

What you’ll learn in this video:
-What the gut microbiome really is (and why it functions like an organ)
-How gut bacteria affect inflammation, insulin resistance, immunity, mood, and ageing
-The 9 daily habits that reliably improve gut health
-Why fibre, diversity, sleep, stress, and movement matter more than supplements
-How ultra-processed foods quietly damage your microbiome
-Why consistency beats intensity for long-term gut repair and longevity
