Excessive sugar consumption can have detrimental effects on overall health and fitness. High sugar intake is linked to increased risk of obesity, diabetes, and various heart diseases. It can lead to fat accumulation, particularly visceral fat, contributing to metabolic syndrome. In fitness contexts, high sugar levels can cause energy spikes followed by crashes, negatively impacting performance and recovery. Reducing sugar intake can enhance insulin sensitivity and support better nutrient absorption, aiding in achieving health and fitness goals.
