Geez, I'm glad random diet dogmatists on Theads are here to educate me on clinical nutrition! 🙏🏽

Performative masculinity is such a joke 😂
I would hate to have to worry constantly about whether our sons or I are 'man enough'...
Live your f*$kin' life. Wear what you want. Be a he/she/they.
Just be a good person and try to leave the world in a better state than you entered it. 🤷🏽‍♂️

🎥 Member Resource Spotlight: The Importance of Co-qualification & Co-registration for Health Coaches

As we prepare for next week’s Ask the Expert: Understanding Scope of Practice & Co-Qualifications, now is the perfect time to revisit this valuable member resource presented by Dr Cliff Harvey.

In this short training video, Cliff explores:
- Why health coaching is not about prescribing
- What co-qualification and co-registration actually mean
- How additional qualifications can ethically expand your scope of practice
- Why professional standards, registration, and client safety matter
- The role of co-qualification in building trust and credibility as a health coach
This practical session provides important context for understanding scope of practice and professional representation — topics that will be explored further during our upcoming Ask the Expert panel.

📌 Available now in the HCANZA Member Resources area (login required).

🎓 A great refresher for experienced coaches and essential viewing for newer members looking to strengthen their understanding of professional standards.

Humans are adaptive omnivores.
There are no populations in human history that have completely eliminated either animal products or plants from their diets.

Despite the marketing buzz, pentadecanoic acid (C15:0) is not an essential fatty acid. 🙅🏽‍♂️
It might plausibly be considered one in the future IF it can be proven that we don't create enough within the body to avoid a universally accepted deficiency syndrome.
But at this stage, the 'essential' moniker is more marketing than science. 💸

"There is no essential carbohydrate" argument isn't the 'gotcha' that Keto zealots think....
Carbohydrates are not an essential nutrient...
However, just because something isn't essential doesn't mean it lacks utility.
People can thrive on low-carb, high-carb, and anything in between. 🤷🏽‍♂️

Just do your research!
The catchcry of the Google Illiterati...
FYI - I'm leading research on SNAS with AUT.
And no, a Vegan diet can't be recommended for people with SNAS...
Which isn't to say it's not a GREAT approach for many people! 🤷🏽‍♂️

Dietary dogmatism doesn't help anyone.

Vegan diets are great for many people...
But it's functionally impossible to follow a solely plant-based sorry if you have a systemic nickel allergy. 🤷🏽‍♂️

Sub-10 % body fat seems to be a 'must have' to be a 'man' 🙄, according to a lot of the alpha bros I see.
But, in reality, who gives a f**k?
I used to be ripped, and I was less healthy, more anxious, and generally less happy than I am now at ~15% body fat. 🤷🏽‍♂️
Of course, physique competitors and weight-restricted athletes might want to hold a lower BF%, but for people wanting to be healthy and strong, anything up to ~20% is fine.
