**What are the potential downsides of a high-carb diet?**
A high-carb diet, particularly when rich in refined carbohydrates and sugars, can lead to several downsides. Such diets may contribute to weight gain, elevate blood sugar levels, and increase the risk of type 2 diabetes and other metabolic disorders. Additionally, excessive carbohydrate intake can lead to energy crashes and mood swings due to rapid fluctuations in insulin levels. It's essential to focus on complex carbohydrates and fiber-rich foods to mitigate these risks while maintaining adequate energy and health.
