🎯 Daily Protein Target
🍽️ Per Meal (based on 4 meals)
🔥 Estimated Calories from Protein
The 4-Calorie Rule: Every gram of protein provides approximately 4 calories. This is useful when calculating your overall daily macronutrient split.
Complete vs. Incomplete: Animal proteins (meat, dairy, eggs) are ‘complete’, containing all 9 essential amino acids. Most plant proteins are ‘incomplete’ but can be combined throughout the day to form a complete profile.
Absorption Myth: The idea that your body can only absorb 20-30g of protein per meal is a myth. While muscle protein synthesis peaks around this amount, the body will still utilise higher amounts for other metabolic processes.
⚠️ Medical Disclaimer: This calculator provides general educational estimates. Individuals with pre-existing kidney conditions should consult a GP or registered dietitian before significantly increasing protein intake.

Hitting Your Protein Goals

Knowing your number is only half the battle. Here is how to practically and consistently meet your daily protein requirements.

1

Anchor Every Meal

Make protein the focal point of every meal. Aim for 20-40g of high-quality protein at breakfast, lunch, dinner, and snacks to evenly stimulate muscle protein synthesis throughout the day.

2

Prioritise Post-Workout Nutrition

While total daily intake matters most, consuming 20-40g of protein within a few hours after resistance training helps maximise muscle repair and recovery.

3

Use Supplements Strategically

Whole foods should be your primary source. However, whey, casein, or plant-based protein powders are convenient, cost-effective tools to bridge the gap if you struggle to hit your target through food alone.

4

Read Nutrition Labels

Many foods marketed as ‘high protein’ are laden with sugar and unhealthy fats. Always check the back of the packet to ensure the protein-to-calorie ratio aligns with your goals.

💡 Pro Tip: Greek yoghurt, cottage cheese, and edamame are incredibly protein-dense, versatile, and affordable options that can easily be added to snacks or meals to boost your daily total.
Prolonged Muscle Soreness: Without adequate protein, your body struggles to repair the micro-tears caused by exercise, leading to extended recovery times.
Constant Hunger: Protein is the most satiating macronutrient. If you feel hungry shortly after eating, your meals may lack sufficient protein and fibre.
Loss of Muscle Mass: If you are losing weight but your strength is plummeting, you may be losing muscle tissue due to inadequate protein intake during a calorie deficit.

Protein Intake FAQ

Answers to the most frequently asked questions about protein consumption, muscle growth, and dietary requirements.

It depends on your goals. For general health and maintenance, 1.2 to 1.6 grams per kilogram of body weight is recommended. For muscle building, aim for 1.6 to 2.2 g/kg. For fat loss while preserving muscle, 1.8 to 2.4 g/kg is ideal.

For healthy individuals, high protein intake (up to 2.5 g/kg) is generally safe and not harmful to the kidneys. However, consistently exceeding this without medical supervision is unnecessary and may displace other essential nutrients like fibre and healthy fats.

Yes, plant-based proteins absolutely count. However, most plant sources (except soy, quinoa, and buckwheat) are ‘incomplete’ proteins, meaning they lack one or more essential amino acids. Eating a varied diet throughout the day ensures you get all the essential amino acids your body needs.

Research suggests that distributing protein evenly across 3 to 4 meals (roughly 20-40 grams per meal) is more effective for muscle protein synthesis than eating the majority of your protein in a single meal.
