One of the most common liver conditions worldwide, and one of the most directly diet-connected.
This page is general education, not a diagnosis. If you're dealing with persistent or severe symptoms, please see a doctor — lifestyle tracking can be a useful complement to medical care, never a substitute for it.
Non-alcoholic fatty liver disease (NAFLD, increasingly called MASLD in updated medical terminology) involves fat accumulation in the liver, often alongside insulin resistance and chronic low-grade inflammation, and has become one of the most common liver conditions studied globally.
Added sugar — particularly fructose — and ultra-processed food are among the most consistently studied dietary contributors to fatty liver risk, tying this condition directly to THE FAD's Food pillar and our sugar deep dive.
Weight management, reduced added sugar and alcohol intake, and regular exercise are the most consistently supported lifestyle factors in research on fatty liver, several of which directly overlap with THE FAD's five pillars.
Diagnosis requires clinical testing — blood tests and imaging, not a lifestyle score. If you've been told you have fatty liver, work with your doctor on monitoring and a specific plan; THE FAD can be a general complement to that, not a substitute.
