使用司美格鲁肽减重时，吃够蛋白质有多重要！

Core Viewpoint - The article emphasizes the importance of adequate protein intake while using semaglutide, a GLP-1 receptor agonist, for weight loss and overall health maintenance [2][5]. Group 1: Importance of Protein Intake - Sufficient protein intake is crucial during semaglutide treatment to maintain muscle mass [2][4]. - A balanced diet including protein, vegetables, and whole grains is recommended to enhance fiber intake and reduce side effects like constipation [2][5]. Group 2: Mechanism of GLP-1 Drugs - GLP-1 receptor agonists promote insulin secretion by activating GLP-1 receptors on pancreatic beta cells, which is glucose-dependent [6]. - They inhibit glucagon secretion from pancreatic alpha cells, helping to lower blood sugar levels [6]. - GLP-1 drugs delay gastric emptying, controlling postprandial blood sugar spikes [7]. - They also regulate appetite by acting on the brain's appetite centers, aiding in food intake reduction and weight management [8]. Group 3: Metabolic Effects - Research indicates that GLP-1 drugs not only increase satiety but also directly influence metabolism [10]. - Individuals using GLP-1 analogs exhibit increased metabolic activity, leading to higher energy expenditure and potential weight loss [11][13].
