The potential consequences of excessive sugar consumption include obesity, type 2 diabetes, and increased risk of heart disease. High sugar intake can lead to weight gain since sugar-laden foods often replace more nutrient-dense options, resulting in an excess caloric intake. Additionally, sugar can spike insulin levels and promote insulin resistance, contributing to metabolic syndrome. Beyond physical health, overconsumption of sugar can negatively impact mental well-being, causing mood swings and energy crashes. Thus, moderating sugar intake is vital for maintaining overall health and preventing chronic diseases.
