Ramadan Fasting’s Effect on Plasma Leptin, Adiponectin Concentrations, and Body Composition in Trained Young Men

Abstract

Lipolysis might have occurred because of increased plasma triglycerides and HDL cholesterol concentrations.

Possible metabolic impact of Ramadan fasting in healthy men

“…6) For cortisol, Al-Hadramy et al reported a reduction and Bahijri et al reported an increase in concentrations (10,11). 7) With respect to renal parameters, conflicting urea concentrations have been reported (2,3,7), and Maislos et al found no significant changes regarding creatinine concentrations (7). Several studies showed a reduction (3,8,12), and other studies no change, in body weight or body mass index (BMI) (4,13) during Ramadan fasting.…”

“…7) With respect to renal parameters, conflicting urea concentrations have been reported (2,3,7), and Maislos et al found no significant changes regarding creatinine concentrations (7). Several studies showed a reduction (3,8,12), and other studies no change, in body weight or body mass index (BMI) (4,13) during Ramadan fasting. 8) Blood pressure during Ramadan fasting has been found unchanged (14), or systolic as well as diastolic blood pressures were reported decreased (15).…”

“…3) For high-density lipoprotein (HDL) as well as low-density lipoprotein (LDL) cholesterol concentrations, conflicting data have been published, (6,7), and no significant changes were described for very low-density lipoprotein (VLDL) cholesterol (4,7,8). 4) Concerning triglycerides, conflicting data have been presented (3,4,6,7). 5) Regarding thyroid parameters, Fadail et al reported a significant rise in total thyroxin and a reduction in triiodothyronine (5), and Sajid et al showed a significant increment in thyrotropin (9).…”

“…2) Insulin was not changed (3,5). 3) For high-density lipoprotein (HDL) as well as low-density lipoprotein (LDL) cholesterol concentrations, conflicting data have been published, (6,7), and no significant changes were described for very low-density lipoprotein (VLDL) cholesterol (4,7,8).…”

“…Many efforts have been undertaken to elucidate the changes of metabolic parameters during Ramadan fasting in healthy subjects, including the following: 1) Regarding blood glucose, significant reductions (1,2) or no significant changes (3,4) have been reported. 2) Insulin was not changed (3,5).…”
