Abstract :
BACKGROUND: Leptin, a peptide contained 146 amino-acids, is mostly secreted from adipose tissue
and it has a critical role on regulation of body weight, body fat mass, appetite, and food intakes. We
tried to review the previous evidence regarding the effects of dietary intakes, including consumption
of carbohydrates, fats and protein on concentrations of leptin concentration.
METHODS: We searched in PubMed search engine to January 2013 by using the following key
words: dietary intake, diet, dietary fat, high-fat diet, dietary carbohydrate, high carbohydrate
diet, dietary protein, high protein diet in combination with leptin, adipokine. Then, we recruited
35 articles to review in the present study.
RESULTS: It seems that beside the amount of fats, type of fatty acids have the key roles on circulating
leptin concentration. Energy intake also significantly associated with the hormone. Studies regarding
the association between carbohydrate intake and concentration of lepton have been reached to
contradictory results. It seems that protein intake can increase the lepton activity.
CONCLUSION: Findings from several studies suggest that a diet display an important role on
change the concentration of lepton.
