Are Carbs Bad for You? Here is the truth.

Carbohydrates often get a bad reputation, with many diet trends promoting low-carb or no-carb eating. But are carbs really bad for you? The short answer: no—it’s about the type of carbohydrates you eat. Let’s dive into the science behind carbs, how they fuel our bodies, and why we should focus on quality rather than cutting them out completely.

How Carbohydrates Work in the Body

When you eat carbohydrates (foods like bread, pasta, or rice), your body breaks them down into glucose—a simple sugar that enters your bloodstream. This glucose is then transported into your cells, where it is used for energy production.

Carbohydrates are our body’s preferred fuel source, providing energy for daily activities, workouts, and essential bodily functions. In fact, our brain relies almost entirely on glucose for fuel—about 99% of its energy comes from glucose metabolism. Without sufficient carbs, you may experience brain fog, fatigue, and difficulty concentrating.

Do You Need to Cut Out Carbs?

Not at all! However, the type of carbohydrate matters. The ones we should be reducing are refined and processed carbs, which provide little to no nutritional value. Examples include:

White bread
Sugary cereals
White rice
Pastries and cakes
Soft drinks and fruit juices

Instead, focus on high-quality carbohydrates that are rich in whole grains and fibre.
