Energy balance
Caloric restriction alone produces significant reductions in liver enzymes (ALT and GGT) in obese metabolic syndrome subjects, and adding moderate-intensity aerobic exercise training provides no incremental benefit on these liver markers.
If you have metabolic syndrome and high liver enzymes, focus on losing weight through a caloric deficit and reducing saturated fats. You do not need to add intense exercise to see improvements in your liver enzymes; diet alone is sufficient for this specific outcome.
Exercise training did not confer significant incremental benefits in this study. ... ALT decreased by 20% in the CR and 24% in the CR+EX group ... corresponding values for γ -glutamyltransferase (GGT) were −28 and −33%, respectively ... (group effect, p = 0.68)
Why this rating
Randomized controlled trial with clear endpoints, though sample size is moderate (n=63) and duration is relatively short (12 weeks).
