Hormonal

Fructose, particularly when consumed in high amounts via beverages, promotes de novo lipogenesis, increases visceral adipose tissue, and impairs insulin sensitivity, contributing to non-alcoholic fatty liver disease and metabolic syndrome.

Be mindful of high-fructose intake, especially from beverages. While fruit is healthy, fruit juice and fruit juice concentrate can deliver high doses of fructose that may harm liver health and insulin sensitivity. Limit fruit juice to small amounts and prioritize whole fruits.
