Why Most Men Over 40 Aren't Eating Enough Protein (And Why It Matters)
If you train regularly, chances are you've been told to "eat more protein."
It's advice that's thrown around in almost every gym, but very few people explain what it actually means or how much protein you really need.
For men over 40, protein becomes even more important. Not because you're getting old, but because your body becomes slightly less efficient at maintaining and building muscle as the years go on. The good news is that with regular strength training and enough quality protein, you can continue building muscle, recovering well and performing at a high level for decades.
Whether you're lifting weights before work, training BJJ, running, playing sport or simply trying to stay fit, making protein a priority is one of the best investments you can make in your health and performance.
Why Protein Matters
Protein is made up of amino acids, often referred to as the building blocks of muscle. Every time you train, you're creating small amounts of muscle damage that your body repairs during recovery. Protein provides the raw materials needed for that repair process.
But protein isn't just about building muscle.
It also plays an important role in supporting your immune system, producing hormones and enzymes, maintaining healthy bones and helping your body recover from the physical demands of training.
If you're consistently falling short on protein, you're making it harder for your body to adapt to the work you're putting in.
How Much Protein Do Active Men Over 40 Need?
If you're training regularly and want to maintain or build muscle, research generally recommends consuming between 1.2 and 2.0 grams of protein per kilogram of body weight each day.
To put that into perspective:
- 80kg: 96-160g of protein per day
- 90kg: 108-180g per day
- 100kg: 120-200g per day
You don't need to obsess over every gram, but having a rough target gives you something practical to work towards.
Signs You Might Not Be Eating Enough
Protein deficiency isn't something most active Australians need to worry about, but many men still don't eat enough to support their training.
Some common signs include:
- Feeling sore for days after training
- Slow recovery between workouts
- Struggling to maintain or build muscle
- Feeling constantly hungry
- Low energy levels
- Plateauing despite consistent training
These issues aren't always caused by low protein intake, but it's one of the first things worth reviewing.
The Best Protein Sources
The good news is that getting enough protein doesn't have to be complicated.
Some of the best whole-food sources include:
- Lean beef
- Chicken
- Fish and seafood
- Eggs
- Greek yoghurt
- Cottage cheese
- Milk
- Lean pork
- Tofu
- Tempeh
- Lentils
- Beans
If you're struggling to reach your daily target through food alone, a quality whey protein shake can be a simple and convenient addition. Just remember that supplements are there to supplement your diet—not replace it.
Don't Forget the Bigger Picture
Protein is incredibly important, but it's only one piece of the puzzle.
If you're sleeping five hours a night, surviving on takeaway and trying to out-train a poor lifestyle, simply adding another protein shake isn't going to solve the problem.
The biggest improvements usually come from combining quality training with good nutrition, adequate sleep, proper hydration and enough recovery between sessions.
When those pieces come together, that's when you'll start seeing the results you're working for.
Final Thoughts
Most men over 40 don't need a more complicated diet.
They need a more consistent one.
Making sure you're eating enough quality protein every day is one of the simplest ways to support muscle growth, improve recovery and continue training at a high level for years to come.
Build each meal around a quality source of protein, aim for around 1.2 to 2.0 grams per kilogram of body weight each day, and stay consistent.
You don't have to be a bodybuilder or professional athlete to benefit. If you're a bloke who still enjoys lifting weights, training, playing sport or simply staying active, protein deserves a place at the top of your nutrition priorities.
