Leptin, a hormone that inhibits hunger and enhances energy consumption, has been discovered to be higher in female children than in their male counterparts [19-25]. This greater male-to-female obesity prevalence in children contradicts the female adult population's predominance of obesity over men, ascribed to a more significant amount of brown adipose tissues [19-22]. This evidence concerns the gene LEP and obesity due to melanocortin 4 receptor deficiency.
