Energy balance

Transitioning from non-obese to obese status or maintaining obesity significantly increases the risk of MASLD, with risk escalating with age and magnitude of weight gain.

Gaining weight, especially transitioning from a normal weight to obese, drastically increases your risk of fatty liver disease. The more weight you gain (especially >20kg), the higher the risk. Maintaining a stable, non-obese weight is the most protective strategy.
