Leptin, often called the "satiety hormone," is produced by fat cells and helps regulate energy balance by inhibiting hunger. Hormones play a crucial role in regulating weight gain and metabolism, influencing how the body stores fat, burns energy, and manages hunger. Several key hormones interact in complex ways to maintain energy balance, and any imbalance in them can lead to weight fluctuations.

Insulin is one of the primary hormones involved in metabolism. Secreted by the pancreas, insulin regulates blood sugar levels by facilitating the storage of glucose in cells as fat. When insulin levels are high, the body tends to store more fat, which can lead to weight gain, especially in people with insulin resistance or type 2 diabetes.

Leptin, often called the "satiety hormone," is produced by fat cells and helps regulate energy balance by inhibiting hunger. When leptin levels are low or when the body becomes resistant to it (common in obesity), people tend to feel hungrier and eat more, which can result in weight gain. On the other hand, ghrelin, known as the "hunger hormone," stimulates appetite.

Produced in the stomach, it increases before meals and decreases after eating. Elevated ghrelin levels can lead to overeating and weight gain, as the hormone signals the brain to consume more food. Cortisol, the stress hormone, also plays a pivotal role in weight regulation.

When stress is chronic, cortisol levels rise, promoting fat storage, particularly around the abdominal area. Hig.
