The Claim

In obese adults, a 12-week plant-based caloric restriction diet results in a significant within-group reduction in liver enzymes (ALT, AST, GGT, ALP) but does not produce a statistically significant difference in liver enzyme levels compared to a conventional calorie-restricted diet.

Supports is higher

Support is ahead, but a single strong opposing study can change this.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

Description
1 study reviewed
In plain English

In obese adults, following a plant-based diet with reduced calories for 12 weeks lowers liver enzyme levels within the group, but the reduction is not greater than that seen in people following a standard calorie-restricted diet.

See the scientific wording

In obese adults, a 12-week plant-based caloric restriction diet leads to a significant within-group reduction in liver enzymes (ALT, AST, GGT, ALP), but no statistically significant difference compared to a conventional calorie-restricted diet, suggesting that caloric restriction alone may be sufficient to improve liver health.

Why this might work

When a person eats fewer calories, the body starts using stored fat for energy. This reduces fat buildup in the liver, which decreases stress and damage to liver cells. As a result, fewer liver enzymes leak into the blood.

    Both groups ate fewer calories, one with mostly plants and one with regular food, and both saw similar improvements in liver health — meaning cutting calories, not eating plants, was the key factor.
