Life-changing moments
that matter

"13 days into the new year, and this is how it’s looking £23.7k cash collected I wanted to say a massive thank you to Jake Carter & Katarina Popovic, and everyone in this community. If I hadn’t have levelled up my knowledge, I’d probably not been able to close clients left, right and centre. I’ve had all types of clients come to me who have worked with other coaches, Drs and even other holistic health coaches. But no one has ever experienced the way I conduct my consultations, and that wouldn’t have happened if I’d never joined the institute. “It’s more important to understand the patient, than the disease the patient has.”"

"My client found no evidence of PCOS after her scan! Last week I had a review scan of my pelvis and everything was clear!! I couldn’t believe it and I was so stoked to find no evidence of PCOS in my scan. My rosacea/eczema is as clear as daylight. I’ve never been happier mentally and physically, and confident about my body again. So, to Coach Dan, I would like to say you have no idea how much I appreciate you for turning my health around. I can’t imagine life without a plan anymore. I don’t think I’ll ever be done with my health and it’s just become a way of life”"

"Ran a simple ‘Christmas Comes Early’ offer for my in-person clients before shifting my focus fully online. I sent a single message using the PDF framework from the treasure chest — and banked £17,000 with a 100% uptake on the offer! This system works, and it works fast."

"In just 10 months, I’ve reduced the time I spend working in my business from 37.5 hours a week to only 8.5 hours — all thanks to what I’ve learned from this amazing team. It’s been such a game changer that I’ve started mapping out exactly how I got here to refine my systems even more. Total freedom, finally!"

“My client transformed his life — blood glucose dropped from 9.6 to optimal, blood pressure went from 162/110 to 113/68, and he completely healed his gut, eliminating reflux and bloating. He lost 29 kg, tripled his strength, and is now managing his autoimmune condition with minimal pain and no medication. Most importantly, he lifted himself out of depression and regained his confidence — inside and out.”

What does an Integrative Nutritional Therapist do?
Plus icon, svg, dark

An Integrative Nutritional Therapist utilises the latest evidence-based research to create an integrative approach to optimising each client’s health and wellbeing.

They design bio-individual nutrition plans, personalise supplementation where appropriate, and interpret functional laboratory data, including blood work, to gain deeper insights, achieve better accuracy and tailor every intervention to the individual.

How is functional medicine different from conventional medicine?
Plus icon, svg, dark

Conventional medicine often waits until a disease is clearly present before intervention begins. Treatment is focused on managing or suppressing a diagnosed condition.

Functional medicine looks upstream. It assesses the early drivers of dysfunction and works to prevent disease from developing in the first place, or restore balance in the body. It uses a whole-systems view of the body, then applies personalised, preventative nutrition and lifestyle interventions to support long-term health rather than only reacting once things have gone wrong.

What will be my scope of practice after completing this certification?
