A common misconception about carbohydrates is that they are inherently unhealthy and should be completely avoided for weight loss. In reality, carbohydrates are a vital source of energy for the body. They are essential for optimal brain function and physical performance. It is crucial to distinguish between refined carbs, which can cause spikes in blood sugar, and whole grains or fruits, which provide nutrients and fiber. Moderation and making informed choices regarding carbohydrate sources can lead to a balanced and healthy diet.
