Protein for Women: Why You Need It and How Much to Eat Daily
Why Protein Matters (Even If You Don't Work Out)
Think protein is only for bodybuilders? Think again. Whether you're smashing six workouts a week or just going for the occasional walk, protein is essential for your health.
Here's what we'll cover:
What protein actually does beyond building muscle
How much women need daily
The best protein sources
Why understanding the "why" changes everything
What Is Protein?
Protein is a macronutrient made up of amino acids—the building blocks your body uses for countless functions.
The Essential Nine
Of the 20 amino acids, 9 are essential, meaning:
Your body can't make them
You must get them through food
They're critical for health
Complete vs. Incomplete Proteins
Complete proteins (all 9 essential amino acids): meat, fish, eggs, dairy, quinoa, soy
Incomplete proteins (missing some amino acids): most plant sources like legumes, grains, nuts
Vego or vegan? Combine different protein sources throughout the day to cover all bases.
5 Ways Protein Affects Your Health (Beyond Muscle)
1. Gut Health: Building Your Protective Barrier
Your gut lining constantly renews itself, and protein provides the building blocks to rebuild it.
Without enough protein, you risk leaky gut—where gaps form in your intestinal wall, allowing gut contents to leak into your bloodstream. This can trigger:
Digestive issues (bloating, reflux, gas)
Skin conditions (eczema, breakouts)
Inflammation
The Stomach Acid Connection
Amino acids produce stomach acid, which breaks down protein. It's a bit of a catch-22: you need protein to make stomach acid, but you need stomach acid to digest protein.
Got digestive issues? Try slow-cooked meats with bones, bone broth, or collagen powder—they're easier to digest and rich in gut-healing amino acids like glutamine and glycine.
2. Skin Health: The Collagen Factor
Amino acids build collagen, essential for:
Skin elasticity
Barrier function
Wound healing
Reducing scarring
Bad news: Collagen production drops off a cliff after 25.
Good news: You can support it with:
Adequate protein intake (glycine, proline, hydroxyproline)
Hydrolysed collagen supplements (type I and III peptides)
Collagen Supplement Tips:
Look for hydrolysed collagen—not products that just contain vitamin C marketed as "collagen support."
Quality Aussie brands:
Chief's collagen powder
Nutra Organics
Practitioner-only brands (higher regulation)
3. Hormones: Stabilising Blood Sugar
Protein is crucial for hormonal balance, particularly through blood sugar regulation.
The Blood Sugar Roller Coaster
Eating carbs alone (white bread, pasta, rice) causes:
Blood glucose spikes
Insulin shoots up
Blood sugar crashes
Energy and mood plummet
Over time, this leads to insulin resistance—linked to diabetes and PCOS.
How Protein Helps
Adding protein to carbs:
Slows glucose absorption
Creates a gentle, stable blood sugar curve
Prevents crashes
Protects against insulin resistance
This supports:
Cortisol regulation (stress hormone)
Oestrogen and progesterone balance
Overall hormonal health
Especially important for: PCOS, PMS, PMDD, irregular cycles
4. Energy: Beat the 3 PM Slump
That afternoon energy crash? It might be your breakfast talking.
Protein stabilises blood sugar, preventing energy fluctuations throughout the day. Plus, protein-rich foods provide:
B vitamins
Iron
Nutrients for red blood cell production
Support for mitochondria (your cells' batteries)
Try this: Boost your breakfast protein to 30g and see if your afternoon slump disappears.
5. Mental Health: Building Better Brain Chemistry
Amino acids create neurotransmitters—your brain's chemical messengers:
GABA: Calms anxiety, promotes relaxation, supports sleep
Serotonin: Elevates mood, creates wellbeing
Dopamine: Motivation and focus
Conditions That May Benefit:
Anxiety
Depression
PMS and PMDD
Mood swings
Important: Mental health is complex. Protein is foundational, but work with qualified professionals for comprehensive care.
How Much Protein Do Women Need?
The Target: 100g Daily
Break it down as:
30g per meal (3 meals)
10-20g from snacks
Protein Content Guide:
Animal sources:
2 eggs: 12g
100g chicken: 22-25g
Palm-sized meat portion: 25-30g
170g Greek yoghurt: 15-18g
Plant sources:
1 cup lentils: 15-18g
Supplements:
1 scoop protein powder: 20-25g
Sample Day (100g):
Brekkie (30g): 3 scrambled eggs + collagen in coffee + cottage cheese on toast
Lunch (30g): Chicken salad + Greek yoghurt
Snack (10g): Protein bar
Dinner (30g): Salmon + quinoa
Whole Foods vs. Protein Powders
Protein supplements are handy when you're time-poor, but prioritise whole foods for:
Iron, B12, zinc, selenium
Fibre (from plant proteins)
Polyphenols (antioxidants)
Better satiety
Choosing Quality Supplements:
Look for:
Whole food ingredients
Natural sweeteners (monk fruit)
Minimal additives
Avoid:
Artificial sweeteners (especially if you have IBS)
Unrecognisable ingredients
Aussie brands worth trying:
Chief's (collagen, bars, biltong)
Health Lab
True Protein
Nutra Organics
Key Takeaways
✓ Aim for 100g protein daily (30g per meal)
✓ Protein supports gut health, skin, hormones, energy, and mood
✓ Pair carbs with protein to stabilise blood sugar
✓ Prioritise whole foods over supplements
✓ Consider collagen if you're over 25
✓ Understanding the "why" motivates the "do"
The Bottom Line
Protein isn't just gym fuel—it's foundational to how your body functions. From rebuilding your gut lining to balancing your hormones and boosting your mood, adequate protein intake can be genuinely game-changing.
As the episode reminds us: "If you understand why you're doing something, you're more motivated to actually do it, and actually doing it is how you get the actual results."
Now you know the why. Time to hit that 100g target.
