Carbohydrates in your diet: what are they and how much do you need per day?

Carbohydrates are often blamed for weight gain. Yet your body needs them as an important source of energy.

The question is therefore not whether you should eat carbohydrates, but which carbohydrates you choose and how much you need per day.

What are carbohydrates?

Carbohydrates are an important source of energy for your body. They provide approximately 4 kilocalories per gram and are converted into glucose in your body.

This glucose is used as fuel for your muscles, organs and brain. When you consume more energy than you burn, some can be stored as glycogen or body fat.

Carbohydrates are found in many foods such as bread, pasta, rice, potatoes, fruit and dairy products.

💡 Did you know? Carbohydrates come in three forms: sugars (simple), starch (complex) and fibre. Fibre is not digested but is essential for your digestion.

What happens to carbohydrates in your body?

When you eat carbohydrates, they are broken down into glucose during digestion. This glucose enters your blood and is then used as energy for your body.

Some of the energy can be temporarily stored as glycogen in your liver and muscles. When more energy is consumed than burned, the excess can ultimately be stored as fat.

Fast and slow carbohydrates

Not all carbohydrates have the same effect on your body.

⚡ Fast carbohydrates

Quickly absorbed into your blood. Cause a rapid rise in blood sugar followed by a dip.

  • Sugar
  • Soft drinks
  • Sweets
  • White bread
  • Fruit juice

🌿 Slow carbohydrates

Digested more slowly. Provide more stable energy and a longer feeling of fullness.

  • Wholegrain cereals
  • Vegetables
  • Legumes
  • Oats
  • Fruit

Complex carbohydrates often contain more fibre and therefore provide a more stable energy level and better blood sugar balance.

Managing carbohydrates smartly

It is not just about the quantity of carbohydrates, but especially about the quality of the carbohydrates you eat.

Choose as often as possible:

  • wholegrain products
  • vegetables and fruit
  • legumes
  • unprocessed foods

Try to limit foods with a lot of added sugars such as soft drinks, sweets and sweet snacks.

Frequently asked questions about carbohydrates

Weight gain occurs when you consume more calories than you burn. This can come from carbohydrates, but also from fats or proteins. Carbohydrates themselves are not the cause of weight gain — total calorie intake and the quality of your diet are the determining factors.

The time at which you eat carbohydrates is less important than your total calorie intake throughout the day. An evening meal with complex carbohydrates such as vegetables or legumes fits perfectly into a healthy eating pattern.

Eating fewer carbohydrates can help with weight loss and stabilising blood sugar. It is important that your diet continues to contain sufficient fibre, vitamins and minerals. If in doubt, consult a nutritionist.

For a low-carb diet aimed at weight loss, a guideline of 100–150 g per day is common. For a ketogenic diet, one goes below 50 g per day. Use the calculator above for a personalised guideline.

Sugars are the simple, quickly absorbable form of carbohydrates. Carbohydrates also include starch and fibre. On food labels, you see carbohydrates split into "of which sugars".
