Weight loss peptides are a class of bioactive peptides that assist in weight loss by regulating appetite, promoting fat metabolism, and improving metabolic function. Their core components are mostly small-molecule proteins, which can be rapidly absorbed by the body and participate in various physiological regulations.
The main mechanisms of action of weight loss peptides:
Suppressing Appetite and Enhancing Satiety: GLP-1 receptor agonists, such as semaglutide and liraglutide, mimic the GLP-1 hormone secreted by the human gut, acting on the appetite center in the brain to send a "satiety" signal, reducing the desire to eat. They also slow down gastric emptying, allowing food to remain in the stomach longer, further prolonging the feeling of fullness.
Promoting Fat Breakdown and Metabolism: Some peptides can activate lipases, accelerating the breakdown process of fat cells and improving energy consumption efficiency, helping to reduce fat accumulation in the body. For example, acetyl hexapeptide can specifically break down fat deposits, improving localized fat accumulation problems.
Regulating Metabolic Health: Weight loss peptides can also improve insulin sensitivity, stabilize blood sugar levels, and reduce the risk of excess calories being converted into fat, which is especially significant for overweight individuals with metabolic syndrome such as hyperglycemia and hypertension.
