Why Protein Is Important for Building Muscle

Muscle growth happens through a process called muscle protein synthesis (MPS)—the repair and rebuilding of muscle fibres after training. Protein provides the amino acids (the building blocks of muscle tissue) your body needs to run this process.

Fuel for growth: Consuming enough protein stimulates MPS, helping your body build stronger, leaner muscle.
Prevents breakdown: Without adequate protein, your body may break down existing muscle tissue to use as energy.
Supports recovery: Protein isn’t just about size—it reduces soreness and helps you bounce back faster for your next workout.

How Much Protein Do You Need?

Here’s where things get real. The amount of protein you need depends on your body weight, activity level, and goals:

Baseline (for general health): The Australian guidelines recommend around 0.84 g/kg/day. That’s the bare minimum.
Muscle building: Research shows the sweet spot is 1.6–2.2 g/kg/day for active adults. Going higher doesn’t provide more benefits for muscle gain.
Older adults: For those over 50, aim for 1.2–1.5 g/kg/day to counter muscle loss with age (sarcopenia).

For perspective: a 75kg active adult looking to build muscle would need between 120–165g of protein per day—spread evenly across meals.

Timing Matters: How to Eat Protein for Maximum Impact

Protein isn’t just about how much you eat—it’s about how you spread it out.

20–30g per meal is the sweet spot to stimulate MPS.
10–20g per snack keeps protein flowing to your muscles throughout the day.
The “anabolic window” myth: You don’t need protein immediately after your workout. As long as you hit your daily target, you’re covered—protein synthesis remains elevated for up to 36 hours after training.

Tips for Incorporating More Protein

Eat protein with every meal – Eggs at breakfast, chicken or tofu at lunch, fish or lentils at dinner.
Snack smart – Greek yoghurt, nuts, cottage cheese, or a protein shake if you’re on the go.
Meal prep – Cook and portion lean meats or plant proteins ahead of time.
Power up your breakfast – Research shows front-loading protein at breakfast kickstarts MPS.
Mix it up – Try quinoa, tempeh, or bean combos for plant-based variety.

Myth-Busting: Protein Edition

Myth #1: You need protein immediately after your workout.

False. Your muscles are ready to rebuild for up to 36 hours post-training.

Myth #2: More protein = more muscle.

Nope. Benefits plateau around 1.6–1.8 g/kg/day.

Myth #3: Plant protein doesn’t work.

Wrong. Smart combos (like rice + beans) give you all the amino acids you need.

Myth #4: High protein damages your kidneys.

Not unless you already have kidney disease. In healthy people, higher-protein diets are safe.

Myth #5: You need protein powder to see results.

Shakes are convenient but optional. Whole foods work just as well.
