Clinical studies have raised concerns regarding reductions in lean body mass during GLP-1RA therapy [40], whereas preclinical studies report improvements in muscle mass and strength [41,42,43]
GLP-1 Receptor Activation: Suppresses appetite through hypothalamic pathways Slows gastric emptying Enhances insulin secretion GIP Receptor Activation: Amplifies GLP-1 satiety effects Improves insulin sensitivity May directly affect fat cell metabolism Glucagon Receptor Activation: Increases energy expenditure (metabolic rate) Promotes fat breakdown (lipolysis) May prevent metabolic adaptation The Advantage: Single molecule means simpler manufacturing, potentially easier regulatory approval, and all three pathways activated with every dose
At the same time, competition is intensifying, with new drugs demonstrating improved efficacy, such as therapies achieving up to 15.3% weight loss and 1.7%2.0% HbA1c reduction in trials
Would destroy peptides and potentially cause serious injection site infections
Two studies also showed concomitant improvements in cognitive measures of recognition and working memory 122 and depressive-like behavior in rats administered antipsychotics 127
It also contains many potent antioxidants such as Vitamin E , Vitamin C, proanthocyanidins, polyphenols, flavonoids, and anthocyanins
