Why is it not advisable to substitute carbohydrate for fats in our diet?

Substituting carbohydrates for fats in our diet can lead to an imbalance in nutrient intake, as both macronutrients play essential roles in overall health. Carbohydrates are the body's primary energy source, especially for the brain and muscles during physical activity, while healthy fats are crucial for hormone production and nutrient absorption. A diet too low in carbohydrates may result in fatigue and decreased performance, while excessive fat intake can lead to weight gain and associated health issues. It's important to maintain a balanced diet that incorporates both macronutrients in appropriate proportions.
