Cortisol and gastrin increase body fat and make people feel hungry, while leptin and thyroxine burn fat.
The above hormones and glands play an important role in losing weight. When you feel hungry, your brain splits and gastrin tells your body that you need food. When you meet your body's nutritional needs, this hormone will be high, so you will always feel hungry. After you eat, the fat cells in your body secrete leptin, telling your brain to stop feeling hungry and start burning fat. The release of leptin tells the body that it is full.
Hormonal disorders can lead to a sharp change in weight. Studies have shown that overweight people have more leptin, and people with leptin resistance have more leptin. Leptin receptors in their bodies can't accept leptin, so neuropeptide doesn't stop secreting. When it stops secreting neuropeptides, it tells the brain that it is no longer hungry. You tell your body to start burning more calories. If neuropeptide continues to act, it will not receive the signal that it is full, so people will not feel full. But when people lose weight, the body will be more sensitive to leptin, and when they are full, they will stop explaining.
