Dean’s 3 Basic Dietary Principles

How to Eat Like a Grown-Up and Reclaim Your Health

In a world overflowing with fad diets, quick fixes, and conflicting advice, it’s easy to forget that your body doesn’t care about trends — it responds to biology.


If you’re tired of the noise and ready to get real about your health, these 3 foundational dietary principles cut through the nonsense. They are rooted in biology, clinical results, and common sense — but they require maturity, responsibility, and consistency. If you’re serious about transforming your energy, your body composition, your brain, and your long-term health trajectory, start here.


1. Minimise Sugar and Refined Carbs

Don’t be a baby about this. You need to grow up.


It’s not a treat. It’s a trap.


We now know with absolute clarity that added sugars and refined carbohydrates are central drivers of metabolic dysfunction — including obesity, type 2 diabetes, fatty liver, PCOS, cardiovascular disease, neurodegeneration, and even some cancers. These ultra-processed carbohydrates spike blood glucose and insulin, hijack your reward system, and trigger inflammation.


You can’t wish your way around this. You can’t “balance it out” with exercise. And you certainly can’t outsmart your biology with willpower alone.


This is not about becoming orthorexic or neurotic. It’s about recognising that childish eating habits — constant snacking, dessert after every meal, sweet drinks, breakfast cereals, energy bars, white bread, and pasta — are incompatible with a body and brain that function optimally.


So, what does it mean to grow up?

• Ditch the daily sugar hits.

• Stop pretending white toast or banana bread is breakfast.

• Get off the blood sugar rollercoaster.

• Start nourishing yourself like someone who respects their future.

2. Responsibly Manage Glycaemic Load, Total Calories, and Inflammatory Foods

Don’t be ignorant about this. You need to put in the critical thinking and intellectual effort.


Health is not an accident — it’s the consequence of choices. And many of those choices hinge on understanding the impact of what you eat.


Managing glycaemic load isn’t just about avoiding sugar — it’s about moderating total carbohydrate intake (even from wholefoods) to match your insulin sensitivity, metabolic health, and lifestyle. It’s about learning what YOUR body can tolerate and respond to well.


Similarly, total calorie intake matters, not because of some outdated “calories in, calories out” dogma, but because excess energy — especially in the context of nutrient-poor, ultra-processed foods — drives fat gain, inflammation, mitochondrial dysfunction, and hormonal disruption.


Add to this the compounding effect of pro-inflammatory foods: industrial seed oils, preservatives, artificial sweeteners, and synthetic additives — and you’ve got a perfect storm.


Time to step up:

• Understand your baseline: get proper testing, measure your insulin, HbA1c, and inflammation markers.

• Reduce reliance on processed food, even “health” food.

• Learn how to balance meals for blood sugar stability.

• Eat with intention, not impulse.

• Don’t outsource your thinking — own your understanding.

3. Prioritise High Biological Value Protein and Volume Mostly Via Vegetables from Above the Ground

Don’t be sloppy and blazé about this. You need to be disciplined and consistent.


Most people are chronically under-eating protein and over-eating energy.


High biological value (HBV) protein — like eggs, grass-fed meats, wild fish, organic poultry, whey, or collagen — provides the essential amino acids required for repair, detoxification, neurotransmitter synthesis, and metabolic health. Without it, you’ll feel weaker, age faster, recover slower, and crave more junk food because your satiety signals are broken.


Vegetables (especially those that grow above the ground) provide fibre, polyphenols, minerals, and prebiotics. They’re anti-inflammatory, help regulate blood sugar, support your gut microbiome, and provide volume — helping you feel full on fewer calories.


Sloppiness here means skipping meals, under-eating real food, grabbing whatever’s convenient, and letting habits slip when life gets busy. Consistency builds momentum. And momentum builds mastery.


Your non-negotiables:

• Aim for 1.5–2g protein per kg of body weight, daily.

• Base most of your meals around a protein + fibre + healthy fat model.

• Eat diverse, colourful, above-ground veg every day.

• Be consistent even when you’re tired, stressed, or travelling.

• Make your default decisions aligned with your goals — not your moods.

Final Thoughts:

This Isn’t Complicated. It’s Just Grown-Up.


If you’re waiting for the next diet hack, supplement stack, or miracle protocol — you’re missing the point.


Before you reach for stem cells, nootropics, peptide therapies, or GLP-1 agonists, you need to master the basics. Because without these foundations in place, you’re not healing — you’re just hacking symptoms.


Eating like a grown-up means:

• Taking responsibility.

• Making deliberate choices.

• Prioritising long-term function over short-term feelings.

• Doing what works — not just what’s popular or easy.
