Why Protein Is So Important—And How to Know If You’re Getting Enough

Why Protein Is So Important—And How to Know If You’re Getting Enough

When most people think of protein, they picture gym sessions, muscle gains or post-workout shakes. But protein isn’t just for athletes—it’s essential for everyone, every day.

Whether you’re building strength, navigating hormonal changes, recovering from injury or just trying to feel more energised, getting enough protein can make all the difference. And at All for One, we often see clients—especially women—under-eating protein without even realising it.

Let’s break down why protein matters, how much you actually need, how your needs change across life stages, and how to know if you’re falling short.


Why Is Protein So Important?

Protein is involved in nearly every critical process in the body—not just building muscle.

Protein supports:

  • Tissue repair (essential for recovery and injury prevention)

  • Hormone production, including insulin, cortisol and sex hormones

  • Immune function, helping you fight infection and recover faster

  • Blood sugar regulation, stabilising energy and mood

  • Neurotransmitter health, impacting sleep, focus and emotional regulation

If you’re not eating enough, your body will start breaking down muscle to keep these systems running.


How Much Protein Do You Actually Need?

The commonly cited RDA (Recommended Dietary Allowance) for protein is 0.8g per kilogram of body weight per day—but it’s important to understand what that number really means.

The RDA was set to prevent deficiency, not to support optimal health, recovery, or performance. For many people, especially women, this baseline falls well short of what’s needed to thrive—particularly if you’re active, managing stress, navigating hormonal changes, or aiming to build or maintain muscle.

Emerging research and clinical practice now support a higher daily intake of 1.2 to 2.0g/kg of body weight, depending on your life stage, training load, and health goals.

Here’s why that higher range matters:

  • Promotes muscle retention and growth, especially during ageing or weight loss

  • Supports hormone balance, including oestrogen and insulin sensitivity

  • Improves recovery from injury, illness, or training

  • Enhances immune function, mood regulation, and metabolic health

  • Helps regulate appetite and cravings, supporting long-term body composition goals

For example, a 70kg woman would benefit more from aiming for 85–120g of protein per day, not just the bare minimum of 56g. And that protein should ideally be distributed across all meals and snacks, not loaded into one sitting.

In short: more protein isn’t just safe—it’s often exactly what your body needs to perform, recover and age well.

 


Signs You May Not Be Eating Enough Protein

You might need to increase your intake if you experience:

  • Muscle weakness or loss

  • Poor recovery after training or injury

  • Persistent fatigue or “brain fog”

  • Cravings or unstable blood sugar

  • Hair thinning, brittle nails, or poor skin healing

  • Frequent infections or slow wound recovery

  • Difficulty maintaining muscle or losing fat


Protein Needs Across Life Stages

In Your 20s–30s:

A key time to build lean muscle, support stress resilience, and lay the foundations for lifelong strength. Protein helps you recover faster and adapt better to training.

In Your 40s–50s:

Muscle mass naturally declines (sarcopenia), especially in women during perimenopause. More protein, paired with strength training, helps support muscle, mood, metabolism and bone density.

In Your 60s and Beyond:

Higher protein intake helps maintain independence, mobility, and reduces risk of falls and frailty.

Pregnancy and Breastfeeding:

Protein needs increase to support tissue growth, hormone production and milk supply. Whole food protein and targeted supplementation can help meet this demand.


What About the Menstrual Cycle?

Throughout the menstrual cycle, your body’s protein needs may fluctuate slightly.

  • Follicular phase (Day 1–14): You’re often more insulin-sensitive and stronger—ideal for strength training. Focus on consistent protein to support lean tissue gains.

  • Luteal phase (Day 15–28): With inflammation and slower recovery more likely, a slight increase in protein can help ease cravings, balance mood, and support tissue repair.

How to Use ChatGPT to Calculate Your Daily Protein Intake

You can use ChatGPT as a tool to estimate your needs and check the protein content of your meals. Here’s how:

1. Calculate Your Daily Target

Ask ChatGPT:

“How much protein should I eat daily if I’m 70kg, active, and want to build muscle?”

Or:

“I’m 65kg, perimenopausal, and do Pilates twice a week. How much protein should I aim for?”

ChatGPT will give you a range based on your weight, activity level and goals (usually 1.2–2.0g/kg/day).

2. Estimate Protein in Your Meals

Send a photo of your food, a nutrition label, or just a description, and ask:

“How much protein is in this?”
“Here’s what I ate for breakfast—how much protein is that?”

ChatGPT can help estimate protein in each item and show you how it adds up through the day.

3. Fill the Gaps

If you’re not quite meeting your target, ask for quick options:

“Give me 3 high-protein snacks with no prep.”
“What can I add to lunch to increase protein without meat?”
“Can you make a smoothie with 30g of protein using almond milk?”

You’ll get fast, practical ideas that match your needs.


The Bottom Line

Protein is more than just a fitness buzzword—it’s one of the most powerful tools for strength, recovery, hormone health, immune resilience and healthy ageing.

Whether you’re building, healing or simply maintaining, making protein a priority is one of the simplest ways to support your whole body, every day.
