Beginner's Guide to Nutrition
Understanding Protein, Carbohydrates and Fats
Introduction
If you’re starting your fitness journey, nutrition can feel confusing. There is so much information online that it’s easy to become overwhelmed.
The good news is that healthy eating doesn’t have to be complicated.
You don’t need to eliminate entire food groups, count every calorie forever or follow strict diets.
Instead, learn the three main nutrients your body needs every day:
- Protein
- Carbohydrates
- Fats
Think of these as the building blocks that help your body function properly.
Protein – The Building Material
Protein is one of the most important nutrients in your diet.
Your body uses protein to:
- Build and maintain muscles
- Repair tissues
- Support healthy bones
- Strengthen the immune system
- Support hormones and enzymes
- Help you stay fuller for longer
Why is protein important?
When people start exercising, especially strength training, protein becomes even more important because your muscles need nutrients to recover and grow.
Eating enough protein may also help:
- Reduce cravings
- Control appetite
- Preserve muscle while losing body fat
- Support healthy ageing

Frequently Asked Questions
Your body needs three macronutrients every day:
- Protein to build and repair muscles and tissues.
- Carbohydrates to provide energy for your brain and body.
- Healthy fats to support hormones, brain function and overall health.
Eating a balance of all three helps your body perform at its best.
A good starting point is 1.6 to 2 grams of protein per kilogram of body weight if you’re exercising regularly or looking to build or maintain muscle.
For example:
- 60 kg = 96-120 g
- 70 kg = 112-140 g
- 80 kg = 128-160 g

Most adults should aim for approximately:
- Women: 2-2.5 litres per day

If you exercise regularly or work in hot conditions, you’ll usually need more.
A simple method is:

- Adjust calories depending on whether your goal is weight loss, maintenance or muscle gain.
This provides a useful starting point that can be refined based on your progress.
Not necessarily.
