Weight loss peptides primarily assist in weight loss by regulating appetite, metabolism, and fat breakdown. Their effectiveness requires a healthy lifestyle and they are mostly prescription drugs; they should not be used blindly.
Weight loss peptides are a class of bioactive peptides that act on the body's metabolic pathways, especially GLP-1 receptor agonists (such as liraglutide, smegglutide, and telpoglutide). They do not directly "burn fat," but rather help control weight through multiple mechanisms:
Suppressing Appetite and Enhancing Satiety: Weight loss peptides activate GLP-1 receptors in the brain (such as in the hypothalamus), sending "satiety" signals to the body and reducing cravings for high-calorie foods. They also slow gastric emptying, allowing food to remain in the stomach longer, thus prolonging satiety.
Regulating Metabolism and Improving Insulin Sensitivity: They can promote insulin secretion, inhibit glucagon release, stabilize blood sugar levels, reduce postprandial blood sugar fluctuations, and thus reduce the risk of fat accumulation. Some peptides can also improve insulin resistance, making them particularly suitable for people with metabolic syndrome.
Promotes Fat Metabolism and Energy Consumption: Certain peptides can activate lipases, accelerating the breakdown of triglycerides into free fatty acids; studies have also shown that they can promote the conversion of white fat to brown fat, enhance thermogenesis, and increase basal metabolic rate.
Significant Clinical Weight Loss Effects, but Varies from Person to Person: Clinical data shows that smegglutide resulted in an average weight loss of approximately 15%, telpoglutide achieved up to 20.9% (SURMOUNT-1 trial), and liraglutide at a daily dose of 1.8 mg resulted in a weight loss of up to 2.6 kg. However, the effects are significantly influenced by individual metabolism, diet, and exercise habits.
