Hormonal

Leptin resistance is a common trait in obesity that impairs the feedback between fat mass and the hypothalamus, leading to dysregulated appetite and energy storage.

In obesity, the hormone leptin, which signals satiety, often stops working effectively (leptin resistance). This means the brain doesn't receive the 'stop eating' signal even when fat stores are high, contributing to continued overeating.
