Excessive carbohydrate intake can lead to several health implications, primarily associated with weight gain and increased risk of metabolic disorders like type 2 diabetes. High carbohydrate consumption can cause spikes in blood sugar levels, prompting the body to produce more insulin. Over time, this might result in insulin resistance, making it difficult to regulate blood sugar effectively. Additionally, an excess of refined carbohydrates can contribute to high levels of triglycerides and low HDL cholesterol, both factors that can adversely affect heart health. Therefore, managing carbohydrate intake is crucial for overall health maintenance.
