Mechanism of Action Comparison# Retatrutide# Retatrutide (LY3437943) is a 39-amino acid synthetic peptide that simultaneously activates three metabolically important receptors: GLP-1 receptor : Enhances glucose-dependent insulin secretion, suppresses glucagon, slows gastric emptying, and reduces appetite through hypothalamic and brainstem signaling GIP receptor : Potentiates insulin secretion, may improve beta-cell survival, and contributes to adipose tissue metabolism and central appetite regulation Glucagon receptor : Increases hepatic energy expenditure, promotes fatty acid oxidation in the liver, stimulates thermogenesis in brown adipose tissue, and enhances lipolysis The glucagon receptor component is the defining innovation
In integrative practice, these effects align with functional medicine principles
And sometimes, you genuinely cannot tell
China now accounts for a quarter of all adults living with diabetes worldwide [1]
Lastly, tirzepatide is also thought to work by slowing gastric emptying (the speed at which food moves through the digestive tract), causing you to feel fuller from your meals
