The Effect of a Six-Week Low-Calorie, Moderate-Carbohydrate Diet on Serum Levels of Lactate Dehydrogenase and Liver Enzymes Following Anaerobic Depletion Activity in Overweight Boys

Increased lactate dehydrogenase and liver enzymes due to debilitating exercise activity in the blood may have devastating effects on the individual. Using low calorie diets with moderate carbohydrates is one of the most important ways to reduce these amounts.

For this purpose, 30 boys weighing 30 were selected by simple random sampling and divided into experimental and control groups based on body composition index. For the experimental group, a low-calorie diet with moderate carbohydrates (carbohydrate share 55% of energy) was set for 6 weeks with a questionnaire of 24% and using food software and with the help of a nutritionist. Dependent t-test was used to study intragroup changes and analysis of covariance with intergroup factor was used for comparison between groups.

The results showed that serum levels of ALP (0.03), AST (0.02) and ALT (0.01) increased significantly by performing one session of anaerobic exercise in both experimental and control groups. Subsequently, the results showed that serum LDH (0.4) levels were not significant after increasing with one session of anaerobic exercise in both experimental and control groups.

The present study showed that consuming a six-week low-calorie, moderate-carbohydrate diet can significantly reduce the resting levels of lactate dehydrogenase and liver enzymes.
