Back to Basics: The Nutrition Principles That Have Stood the Test of Time

Lately, I've been talking a lot about the mindset side of weight loss, the emotional patterns, self-sabotage and deeper work that creates lasting change.

So today, I wanted to come back to my roots and talk about nutrition and the basics that have stood the test of time, and for good reason! You may even say we are heading back to the Future (some of these principals we have been banging on about for years but the science is just catching up)!

I've been a nutritionist for over 20 years, and during that time I've seen countless diets, trends and miracle solutions come and go. Every year there's another "best way to eat," another food we're told to fear or another supplement that's meant to change everything.

Yet despite all the noise, there are a handful of nutrition principles that have remained exactly the same.

And they remain for good reason.

They form the basis of a solid nutritional foundation that, with a few personalised tweaks, can create incredible long-term health and sustainable weight loss.

The nutrition world feels louder than ever right now, which is exactly why I think it's important to come back to the basics.

So many women come to me wanting to try another plan, another challenge or another diet, hoping this one will finally be the answer.

But I often find myself asking a much simpler question:

Are you consistently doing the basics?

If the answer is no, that's always where we start.

Because why are we always looking for something new when the answers are often sitting right in front of us?

Why the basics still work

There's a quote I've been thinking about lately:

"We often overestimate what the latest diet can do for us and underestimate what six months of consistently eating enough protein, fibre and vegetables can do."

After more than 20 years in practice, I honestly believe that's true.

We're conditioned to think the answer is out there somewhere, a new eating plan, a new protocol or a magic solution.

But our bodies respond remarkably well to consistency.

Eating enough protein every day.
Getting enough fibre.
Filling your plate with colourful vegetables.
Drinking enough water.
Moving your body.
Sleeping well.

None of these things are particularly exciting, but together they create a powerful foundation for better energy, improved metabolism, hormone health and sustainable weight management.

Before chasing another plan, ask yourself:

"Have I actually mastered the basics?"

Because if the answer is no, your energy is often better spent building those habits than searching for another diet.

Foundation One: Prioritise Protein

Protein is hyped up at the moment and again for good reason.

One of the most common things I see in clinic is women simply not eating enough of it.

Protein helps maintain muscle mass, supports metabolism, keeps you fuller for longer, stabilises blood sugar and plays an essential role in healthy ageing.

This becomes even more important during peri-menopause and post-menopause when we naturally lose muscle more easily.

A simple place to start is aiming for around 30g of protein at each meal.

For many women, an even better long-term goal is around 1.5–2g of protein per kilogram of body weight each day, depending on your activity levels and individual needs.

What does 30g of protein actually look like?

• 120g cooked chicken breast = approximately 30g protein

• 150g lean beef steak = approximately 32g protein

• 150g turkey breast = approximately 32g protein

• 150g white fish (barramundi, snapper or cod) = approximately 30–32g protein

• 180g salmon fillet = approximately 36g protein

• 170g Greek yoghurt with one scoop of protein powder

• 200g firm tofu = approximately 30g protein

• 150g tempeh = approximately 30g protein

• 1½ cups cooked edamame beans = approximately 28–30g protein

• Protein smoothie made with 1 scoop protein powder + 250ml milk + 200g Greek yoghurt = 40g+ protein

Simple ways to increase your protein intake

You don't need to completely overhaul your diet. A few small changes can make a big difference.

• Start your day with protein. Swap cereal or toast alone for eggs, Greek yoghurt or a protein smoothie to help keep you fuller for longer.

• Build your meal around the protein first. Ask yourself, "What's my protein?" and then add vegetables, healthy fats and carbohydrates around it.

• Add, don't restrict. Stir Greek yoghurt into breakfast, add chicken or legumes to salads, or include cottage cheese with eggs. Sometimes adding is easier than taking away.

• Choose protein-rich snacks. Greek yoghurt, boiled eggs, cottage cheese, edamame or a protein smoothie will satisfy you for much longer than highly processed snack foods.

• Ask yourself one simple question: "Where's the protein?" before every meal and snack. This one habit alone can dramatically improve the quality of your diet without needing to count every gram.

Foundation Two: Don't Forget Fibre

If protein is getting all the attention, fibre is the quiet achiever.

Fibre supports gut health, blood sugar balance, cholesterol levels, hormone metabolism and keeps us feeling fuller for longer.

Yet most people eat far less than they need.

Aim for around 25–35g of fibre each day by including plenty of:

• Vegetables

• Fruit

• Oats

• Legumes

• Nuts

• Seeds

• Whole grains

One of my favourite habits is simply asking myself:

"Where's the fibre?"

Could I add berries to breakfast?

Extra vegetables to lunch?

Chickpeas to a salad?

Some chia seeds to my yoghurt?

Small additions quickly add up.

Foundation Three: Eat More Colour

One of the simplest recommendations I give clients is this:

Aim for at least three handfuls of colourful vegetables every day.

Different coloured vegetables provide different vitamins, minerals and antioxidants, all supporting different aspects of health.

Think:

🟢 Green: broccoli, spinach, kale, green beans, asparagus, zucchini, cucumber, Brussels sprouts

🔴 Red: tomatoes, red capsicum, radishes, red cabbage, beetroot, cherry tomatoes

🟠 Orange & Yellow: pumpkin, carrots, sweet potato, butternut squash, yellow capsicum, corn

🟣 Purple & Blue: eggplant, purple cabbage, purple carrots, red onion, purple sweet potato

⚪ White & Brown: mushrooms, cauliflower, onions, garlic, parsnip, turnip

The more variety you eat, the more diversity you're feeding your gut microbiome and that's one of the best things you can do for your overall health.

Foundation Four: Hydrate Properly

Hydration sounds almost too simple to matter, but it really does.

Even mild dehydration can contribute to fatigue, headaches, poor concentration and increased hunger.

Many people mistake thirst for hunger and end up eating when what their body really needs is water.

For most people, aiming for around 2 litres per day is a great place to start, increasing this if you're active or exercising regularly.

Carry a water bottle.

Sip consistently throughout the day.

Don't wait until you're thirsty.

The power of consistency

If you picked just protein and fibre and focused on improving those two things consistently over the next few weeks, I'd be willing to bet you'd notice positive changes.

Better energy.

Improved digestion.

Reduced cravings.

Greater fullness after meals.

Improved body composition.

Better overall health.

Not because you followed the latest trend, but because you built a stronger foundation.

That's the thing about nutrition.

It isn't usually the complicated things that move the needle.

It's the simple things done consistently.

Nutrition is only part of the story

The unique combination of my work is that I combine evidence-based nutrition with mindset and weight loss therapy because I truly believe both are equally important.

You can have the perfect meal plan, but if stress, perfectionism, emotional eating or all-or-nothing thinking keep pulling you off track, knowledge alone won't create lasting change.

Likewise, mindset work without nourishing your body misses an equally important piece of the puzzle.

In my experience, women rarely struggle because they don't know what to eat.

They struggle because life gets busy.

Because emotions take over.

Because they expect perfection.

Because they abandon the plan after one bad meal instead of returning to the next one.

That's why lasting transformation comes from understanding both your body and your mind.

Before you look for another diet...

Come back to these foundations.

Pick one habit.

Master it.

Then add another.

You don't need to change everything overnight.

You just need to become consistently better than you were yesterday.

And if you're already doing all of these things consistently and still not getting the results you want, it may be time for a more personalised approach.

Reply to my newsletter and tell me what you're already doing well, and I'll happily share what I think your next step could be.

Sometimes that next step is refining your nutrition.

Sometimes it's looking at stress, sleep or hormones.

And sometimes, it's doing the deeper emotional work that allows healthy habits to finally stick.

Because after 20 years of working with women, one thing has become very clear:

The women who achieve lasting results aren't the ones who find the perfect diet. They're the ones who build a solid foundation and keep coming back to it.

Until next time,
