Hormonal

Mutations in the preproghrelin/ghrelin gene are associated with obesity in humans, suggesting a genetic basis for energy balance regulation via the ghrelin pathway.

If you have a family history of obesity, it may be partly due to genetics affecting your hunger hormones (ghrelin). This doesn't mean you are doomed, but it does mean you might need to be more mindful of hunger cues and food environments than someone without this genetic risk. Consult a healthcare provider for personalized advice.
