Protein is one of the most talked-about nutrients in the fitness world—but it’s also one of the most misunderstood.

Some people believe everyone should drink multiple protein shakes a day, while others think protein is only important if you’re trying to build muscle. The truth lies somewhere in between.

Whether your goal is losing weight, gaining muscle, improving recovery, or simply maintaining good health, getting the right amount of protein is essential.

Protein helps your body:

• – Build and repair muscles
• – Support healthy bones
• – Produce enzymes and hormones
• – Maintain healthy skin, hair, and nails
• – Support your immune system
• – Keep you feeling fuller for longer

One question we hear frequently is:

“How much protein do I actually need every day?”

The answer isn’t the same for everyone. Your ideal intake depends on factors such as your body weight, age, activity level, and personal goals.

In this guide, we’ll explain everything you need to know in simple language—without the confusing science jargon.

What Is Protein?

Protein is one of the three major macronutrients, along with carbohydrates and fats.

It is made up of smaller building blocks called amino acids. These amino acids are used throughout the body to repair tissues, build muscle, produce enzymes, and support countless everyday functions.

Unlike carbohydrates and fats, your body doesn’t store large reserves of protein. That means it’s important to consume enough protein regularly through your diet.

Good sources include:

• – Chicken
• – Fish
• – Eggs
• – Greek yogurt
• – Milk
• – Lentils
• – Beans
• – Soy products
• – Nuts and seeds
• – Whey protein

Why Is Protein Important?

Protein isn’t just for bodybuilders. Every cell in your body depends on it.

Here are some of the key benefits:

Supports Muscle Repair

Exercise creates tiny tears in your muscle fibres. Protein provides the amino acids your body needs to repair and strengthen those muscles.

---

Helps With Weight Management

Protein is more filling than carbohydrates or fats, which may help you feel satisfied for longer and reduce unnecessary snacking.

---

Supports Healthy Ageing

As we age, we naturally lose muscle mass. Eating enough protein alongside regular strength training can help maintain muscle and functional strength.

---

Supports Everyday Body Functions

Protein plays a role in producing enzymes, hormones, antibodies, and other essential compounds that keep your body functioning normally.

How Much Protein Does the Average Adult Need?

One commonly referenced recommendation for healthy adults is 0.8 grams of protein per kilogram of body weight per day. This is intended to meet the basic needs of most sedentary adults. However, if you’re physically active, trying to build muscle, or aiming to lose weight while preserving lean mass, your protein needs are often higher.

Here’s a simple guide:

Activity Level	Approximate Protein Intake
Sedentary Adult	0.8 g/kg
Lightly Active	1.0–1.2 g/kg
Regular Exercise	1.2–1.6 g/kg
Strength Training	1.6–2.2 g/kg
Fat Loss While Training	1.6–2.4 g/kg (depending on individual needs)

These ranges are general guidance. Individual needs can vary based on overall health and specific circumstances.

How to Calculate Your Daily Protein Requirement

The basic formula is:

Body Weight (kg) × Protein Target (g/kg)

Example 1

Weight: 60 kg

Moderately active:

60 × 1.2 = 72 grams of protein per day

---

Example 2

Weight: 75 kg

Strength training:

75 × 1.8 = 135 grams of protein per day

---

Example 3

Weight: 90 kg

Fat loss with resistance training:

90 × 1.8 = 162 grams of protein per day

Remember, these are examples. Your ideal target should reflect your activity level, goals, and advice from a qualified healthcare professional if you have medical conditions.

Do You Need to Eat All Your Protein at Once?

No. Your body can digest and absorb protein throughout the day. Instead of eating one very high-protein meal, many people find it practical to spread their protein intake across breakfast, lunch, dinner, and snacks. This can also make it easier to reach your daily target.

EatWorkFit Expert Tip

Don’t focus only on hitting a number. Choose high-quality protein sources, eat a balanced diet, stay active, and be consistent. Small improvements repeated every day often lead to better long-term results than chasing perfection.
