However, no published clinical trial has confirmed that taking the finished product as an oral capsule results in measurably increased GLP-1 levels in humans

These changes can make a big difference

The mismatch between low leptin (signaling starvation) and high body fat (actual energy stores) drives rebound hyperphagia

Where GLP-1 Receptors Are Located: Pancreas (insulin and glucagon regulation) Stomach (slowing emptying) Brain (appetite control) Heart (cardiovascular benefits) Liver (glucose production regulation) How Tirzepatide Works: Dual GIP and GLP-1 Receptor Activation: Tirzepatide activates two hormone receptors instead of one, creating a more comprehensive metabolic effect: GLP-1 Effects (Same as Semaglutide): Increased insulin secretion Decreased glucagon production Slowed gastric emptying Reduced appetite through brain signaling Enhanced satiety Additional GIP Effects: GIP (glucose-dependent insulinotropic polypeptide) adds complementary benefits: Enhanced Insulin Response: GIP amplifies insulin secretion even more than GLP-1 alone, particularly after meals when blood sugar is elevated

The differences between our study and their study were that heart dilation and systolic dysfunction were present because of 16 weeks follow-up in their study
