Does fasting affect liver enzymes? Abstract. Effect of 24-hour fasting on liver enzymes involved in G-6-P utilization (phosphoglucomutase, phosphohexoseisomerase and G-6-P dehydrogenase) was studied. The 24-hour fasting caused a decrease in liver mass and an increase in cellularity . Total cellularity, however, did not change.
Does fasting help lower liver enzymes?
Fasting plasma glucose and HbA1c levels significantly decreased in all groups. Liver enzymes also decreased after the fasting intervention, except for AP in patients with T2DM . The same was found for blood lipids.

How long does it take for AST and ALT to return to normal?
| Marker Time to return to normal limits | Aspartate aminotransferase 7 days , but considerable variability in declines with abstinence | Alanine aminotransferase Unknown | Macrocytic volume Unknown but half–life ∼ 40 days | Carbohydrate–deficient transferrin 2–4 weeks of abstinence |
