Leptin is a neat little hormone that tells us when we’ve had enough to eat.
If there’s a hormone for this, why do we often tend to overeat?
Note: While this video focuses on leptin, other players (ie: hormones like orexin and ghrelin) also influence appetite. It’s important to remember that the body is incredibly complex, and there are always a number of factors at play!
It should also be noted that the general process discussed in this video is not as instantaneous as I make it out to be! The amount of leptin released is directly proportional to the amount of body fat that an individual has — and that body fat does not increase instantaneously when you eat 3 mini eggs. On the whole, an individual with more body fat will have higher levels of leptin in their circulation than an individual with less body fat.
