High-sugar diets can have detrimental effects on physical health. Excessive sugar consumption is linked to various health issues, including obesity, diabetes, and heart disease. Sugar provides empty calories that hinder nutrient intake and increase overall caloric consumption without satisfying hunger. Additionally, high-sugar diets can lead to insulin resistance, contributing to metabolic syndrome. They may also affect mood and energy levels, resulting in cycles of energy spikes and crashes. Reducing sugar intake and opting for a balanced diet can greatly enhance physical health and overall well-being.
