🍎 What is a Calorie?
Think of your body like a car. The car needs petrol to run. Your body needs calories to run. Calories are simply the energy that comes from the food and drinks you consume every day.
Without enough calories, you feel tired, weak, and cannot concentrate properly. With too many calories, your body stores the extra energy as fat. The goal is to eat the right amount for YOUR specific body and YOUR specific lifestyle.
📊 How Many Calories Does an Average Person Need?
Here are the general guidelines from health organisations worldwide:
- Women — about 1,600 to 2,400 calories per day
- Men — about 2,000 to 3,000 calories per day
- Children (8 to 12 years) — about 1,400 to 2,200 calories per day
- Teenagers — about 1,800 to 3,200 calories per day
But these are just averages! Your exact number depends on much more than just your gender.
🎯 What Decides How Many Calories YOU Need?
- Your age — children and teenagers need more calories for growth. Older adults need slightly fewer.
- Your height and weight — bigger bodies need more energy to move and function every day.
- How active you are — someone who exercises every day needs many more calories than someone who sits at a desk all day. This can be a difference of 500 to 1,000 calories per day!
- Your health goals — wanting to lose weight means eating slightly less. Wanting to build muscle means eating slightly more.

🍝 What Are Calories Made Of?
All the calories in your food come from three main groups:
- Carbohydrates (rice, bread, pasta, fruit) — 4 calories per gram
- Protein (meat, fish, eggs, lentils, beans) — 4 calories per gram
- Fat (oil, butter, nuts, avocado) — 9 calories per gram (more than double!)
A healthy, balanced diet includes all three. The problem for most people is eating too much fat and refined carbohydrates (like sugary drinks and white bread) and not enough protein and vegetables.
💪 Smart Calorie Tips for a Healthier Life
- Drink water instead of sugary drinks. A single can of cola has 150 calories and zero nutrition!
- Eat slowly. Your brain takes about 20 minutes to feel full. Eating fast means you eat more than you need before your brain gets the signal.
- Fill half your plate with vegetables at every meal — high in nutrition but low in calories.
- Do not skip breakfast. It helps control hunger and energy levels for the whole day.
- Snack on fruit and nuts instead of biscuits and crisps.
❓ Frequently Asked Questions
What happens if I eat too few calories?▼
If you eat too few calories, your body may slow your metabolism and start breaking down muscle for energy. You will feel tired, weak, and unable to concentrate. Never go below 1,200 calories (women) or 1,500 calories (men) without medical supervision.
How do I use calorie counting to lose weight?▼
Creating a 'calorie deficit' — eating slightly less than you burn — causes weight loss. A deficit of 500 calories per day leads to about 0.5 kg of weight loss per week. Use our Calorie Calculator to find your maintenance calories first, then reduce by 500.
Are all calories the same?▼
The number is the same, but the nutritional value is completely different! 100 calories of vegetables gives you vitamins, minerals, and fibre. 100 calories of chocolate gives almost no nutrition. Choose nutritious, filling foods within your calorie target.
How many calories does exercise burn?▼
It varies greatly. A 70 kg person burns roughly: walking 30 minutes = 150 calories, cycling 30 minutes = 250 calories, running 30 minutes = 300 calories. Note: diet has a bigger impact on weight than exercise for most people.
Should children count calories?▼
Children should not count calories. They should eat a balanced diet and follow their natural hunger signals. Only in specific medical situations should children monitor calories, and always under a doctor's guidance.
