A common misconception about carbohydrates in a fitness diet is that they should be completely avoided for weight loss. In reality, carbohydrates are a primary energy source essential for maintaining athletic performance and overall health. The key is to focus on complex carbohydrates, such as whole grains, fruits, and vegetables, while limiting refined sugars and overly processed carbs. A balanced intake can help fuel workouts and support recovery, making carbohydrates an important component of a healthy diet.
