Energy balance

Achieving a weight loss of greater than 9% of body weight is associated with significant improvements in hepatic histology (steatosis, ballooning, inflammation) and insulin sensitivity in NASH patients.

To see actual improvements in your liver's structure (reduced inflammation and fat damage), you need to lose more than 9% of your body weight. Losing 5-9% will still help your blood sugar and liver fat, but hitting that 9% mark is key for reversing the active damage of NASH.

GoodQualifiesHIGH confidence
Comparing subjects who lost >9% of body weight (n = 16), to those that did not (n = 25), improved insulin sensitivity (P < 0.001), adiponectin (P = 0.03), steatosis (P = 0.005), ballooning (P = 0.04), inflammation (P = 0.045), and nonalcoholic fatty liver disease activity score (P = 0.009) were seen.

Why this rating

Subgroup analysis of a randomized trial; while not a separate RCT, the stratification is clear and statistically significant.
