Relationship between obesity and serum resistin, apelin, and sterol regulatory element binding protein-1c levels: the changes in the analyte levels durin g weight loss in obese patients

Considering the insulin-like effects of apelin, high levels of apelin in prediet/exercise phase can be interpreted as a kind of resistance to apelin, and the decreased postdiet/exercise apelin levels as a kind of normalization of it. The decrease in hemoglobin A1c and triacylglycerol, triglycerides levels following weight loss can be appreciated. High basal serum sterol regulatory element binding protein-1c levels suggest an increase in lipogenesis. The increases in glucose and low-density lipoprotein-cholesterol after diet/exercise program remain in a physiological range. However, we think that a longer diet/exercise follow-up in a larger population will further elaborate on the issue.
