Abstract
In a previous meta-analysis, we showed that long-term melatonin
administration minimizes diet-induced changes in lipid profiles.
The present work was aimed to use a meta-analysis to study the diet-denendent
effect of melatonin monotherapy on body weight gain (BWG) and eating
behavior in rats. We carried out a meta-analysis of 43 publications
examining the effects of melatonin monotherapy on BWG, blood leptin
levels, food and water intake in rats fed a standard diet (37 publications),
as well as high-fructose (5 publications) and high-fat (9 publications)
diets. Our findings suggest that although melatonin reduced triglyceride,
total cholesterol and leptin levels in rats fed high-fructose and
high-fat, but not a standard, diets, melatonin therapy prevented
BWG in rats on either diet. Increasing the dose of melatonin did
not enhance the effect of therapy on any diet. We did not obtain
convincing evidence that the effect of melatonin depends on the
initial body weight and age of rats. On a standard diet, melatonin has
been found to reduce food and water intake. Melatonin did not reduce
BWG with a standard diet when administered intraperitoneally. Our
research suggests that melatonin may be beneficial in diet-induced
metabolic disorders as it improves lipid profiles and prevents BWG.
However, a decrease in appetite and BWG when taking melatonin may
also be due to negative side effects of the drug, which requires
further research.
