Walk down any supermarket aisle and you'll see it: the "proteinification" of everything. Protein coffee. Protein cereal. Protein yoghurt. Protein water.
Brands are slapping the word on everything. Why? Because people who actually push themselves, from hybrid athletes to everyday athletes, are finally waking up to a simple truth: the old nutrition rules were wrong. You need more protein than you've been told. But chasing that number through processed shakes and snacks is bad for your long-term health, and it's expensive.
Here's exactly how much protein you need per day, and how to hit it without eating six times a day.
The RDI was built to keep you alive, not strong
Most of the confusion comes from outdated government guidelines. Those targets were designed to prevent basic deficiency - not to help you recover from a hard session, build strength, or hold onto muscle as you age. There's a world of difference between "not sick" and "strong."
The baseline (survival): The UK's Reference Nutrient Intake (RNI) is a flat 0.75g of protein per kilogram of body weight per day. Australia's Recommended Dietary Intake (RDI) is 0.75g/kg for women and 0.84g/kg for men. That's the floor. It's the least you can eat before your body starts complaining.
The performance & longevity target: Modern longevity and performance research, the kind Dr. Peter Attia and sports-nutrition bodies point to, lands much higher. To build and maintain muscle, recover properly, and age like someone who intends to stay strong, the target shifts to 1.6g to 2.2g per kilogram of body weight per day. That's not a fringe opinion. It's where the muscle-protein research consistently settles.
The proteinification trap
Let's take a hypothetical 80kg athlete. To hit 2.0g/kg, you need 160g of protein a day.
Here's the trap: you try to get there by bolting on a protein iced coffee (15g), a protein yoghurt (15g), and a protein bar (20g) on top of your normal meals. Suddenly you're spending a fortune on ultra-processed snacks just to chase a number. The volume alone can feel like a part-time job, and it'll leave you bloated before you've even trained.
Protein-fortified doesn't mean good. These "high-protein" snacks are ultra-processed and packed with sugar and fillers.
What 160g of protein actually looks like in a day
To understand why whole foods alone are so hard to rely on, look at what 160g of protein in a single day actually demands. Eat strictly whole foods and your day looks something like this:
- Breakfast (30g): 3 whole eggs and 2 slices of wholemeal toast.
- Morning snack (20g): 1 cup of plain Greek yoghurt.
- Lunch (40g): A large salad with 150g (about a palm-and-a-half) of cooked chicken breast.
- Afternoon snack (15g): A large handful of almonds and a hard-boiled egg.
- Dinner (55g): 200g of cooked salmon with quinoa and broccoli.
That's five deliberate, protein-anchored meals. Every day. Miss one and you're already 20-40g short. For most people juggling work, family, and training, that's not sustainable.
The shortcut: one scoop instead of a supplement shelf
Hitting a high protein target every single day is exhausting and expensive - especially when you're balancing a career, a family, and serious training all at once.
That's the whole reason Rare Forms exists. One scoop combines high-quality protein with clinically-dosed functional ingredients, plus the key vitamins and minerals your body actually uses. Instead of juggling a protein tub, a separate multivitamin, and a bag of creatine, you get them in one efficient, high-quality drink. It cuts the hassle, saves you time, and stops you leaning on mediocre "protein-fortified" supermarket snacks to close the gap. One drink. All your needs.
Your protein action plan
Don't guess your nutrition. Treat it like a training block.
-
Calculate your true target. Use the daily protein calculator below to find your specific number based on your weight and your goal.
-
Audit your baseline. Log your normal meals for three days. You'll see the gap between what you eat and what you need - fast.
- Supplement smartly. Use one multi-purpose scoop to close that gap without forcing down extra meals.
Protein FAQs
How much protein do I need per day?
To avoid deficiency, around 0.75g per kg of body weight (the UK RNI and Australian female RDI; 0.84g/kg for Australian men). But to build or maintain muscle and support healthy ageing, aim for 1.6g to 2.2g per kg per day. An 80kg adult targeting the higher end needs roughly 160g of protein daily.
How much protein do I need to build muscle?
Research on muscle growth consistently points to roughly 1.6g to 2.2g of protein per kg of body weight per day, spread across the day, alongside resistance training. Going far above that range adds little extra muscle for most people.
Can I get enough protein from food alone?
Yes, but it's hard to do every day. Hitting 160g from whole foods means five deliberate, protein-anchored meals daily. Most busy people fall short, which is where a high-quality protein supplement makes the target realistic.
Is too much protein bad for you?
For healthy adults, intakes in the 1.6–2.2g/kg range are well tolerated and supported by the research. If you have a medical condition, talk to your doctor before making big changes.
How much protein do I need after 40 or 50?
More, not less. Muscle mass naturally declines with age, so older adults often benefit from the higher end of the range (closer to 2.0g/kg) to defend against muscle loss and stay strong and mobile.
Is it better to get protein from food or supplements?
Whole foods first, always. They bring fibre, micronutrients, and satiety. Use a supplement to close the daily gap efficiently rather than replacing meals entirely. The goal is hitting your number consistently without turning eating into a chore.
