The connection between sugar intake and weight gain primarily revolves around the consumption of added sugars, which can lead to excess calorie intake. Sugary foods and beverages often provide little to no nutritional value, promoting increased hunger and cravings. In addition, high sugar consumption can affect the regulation of insulin, potentially leading to insulin resistance and enhanced fat storage. Furthermore, sugary diets can lead to increased fat accumulation, especially around the abdominal area, associated with health risks. Moderating sugar intake is crucial for maintaining a healthy weight and metabolic health.
