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.

Fructose, when consumed at high levels, has critical adverse effects... Fructose consumption as a risk factor for non-alcoholic fatty liver disease... Moderate amounts of fructose consumption impair insulin sensitivity in healthy young men.
Why this rating
Supported by randomized controlled trials and meta-analyses showing metabolic changes.

- Initial treatment for type 2 diabetes should be a combination of metformin and either an SGLT-2 inhibitor or a GLP-1 receptor agonist to achieve cardiorenal protection, rather than monotherapy or older agents like sulfonylureas.Strong
- For patients with specific monogenic obesity syndromes (leptin deficiency, POMC/PCSK1/LEPR mutations), targeted pharmacotherapy (recombinant leptin or setmelanotide) is highly effective and should be prioritized, unlike in polygenic obesity.Strong
- Continued weekly administration of 2.4 mg subcutaneous semaglutide prevents weight regain and promotes further weight loss in adults with overweight or obesity, whereas switching to placebo results in significant weight regain.Strong
