"I've spent years studying nutrition, but the second a client says, 'My favorite influencer said seed oils/carbs/dairy are toxic,'
I feel like I'm suddenly on trial. I know the science, but in that moment, I'm terrified that if I can't dismantle their 30-second TikTok video on the spot, they'll think I don't know what I'm doing."
"Clients come in showing me a meal plan ChatGPT generated in 5 seconds. It's frustrating because Al sounds so confident, but it has zero clinical context or safety testing.
How do I show them that free instant answers aren't the same as personalised care?"
"Whenever a client arrives convinced that a viral detox or juice fast will cure them, I freeze. If I tell them it's a fad, they feel judged and shut down. If I dump a bunch of research papers on them, they get overwhelmed. I'm stuck trying to correct dangerous trends without losing their trust."
"It feels like the loudest, most extreme voices online get all the engagement, while those of us with actual qualifications are left trying to explain quiet, scientific nuance. I want to build
credibility without having to become a loud social media creator or give black-and-white advice just to be heard."
"When a client challenges my recommendations with something they read on Google, my natural reaction is to start over-explaining the science just to prove my credentials"

This program should be part of the curriculum for medical students... I am looking forward to branching out into serving clients from the Nutrition Skills I am learning through the Clinical Nutrition Program!"
Discover how you can grow bigger with your learning, earnings, savings, and impact in 2027 with the CEO of The Health Sciences Academy, Maurice Castelijn.
How to challenge misinformation without losing their trust
How Impostor Syndrome holds back your nutrition career and ways to overcome it
The specialisations where opportunities are growing with you
And how to become the obvious choice
How to set your fees without underselling yourself
Even when a client knows what they want, reads about what to do, pays to learn how to do it, asks ChatGPT to put together a meal plan - this know-how alone may not result in any change whatsoever.
Your client may be super excited in the beginning, but then life happens. And if we don't prepare for those situations, we'll be taken by surprise.
So our goal is to help you understand how to adapt what you know to different clients, situations, and behaviours - and help make change happen.
