HCG Diet Information HCG is the hormone that women produce during pregnancy to help with weight gain and control insulin levels. Studies show that HCG suppresses appetite because it’s similar in structure to an orexigenic hormone called ghrelin. Ghrelin stimulates hunger while suppressing production of the hormone leptin, which is responsible for telling your brain when you’ve had enough to eat. HCG influences ghrelin and results in a reduction in hunger. This leads to an increase in metabolism that helps burn more calories. HCG also suppresses insulin production and decreases glucose levels by either slowing down how quickly it enters the bloodstream or by converting it to glycogen. https://www.hcgdietsystem.co.za/hcg-diet-information/
