That's not even close to how these drugs work. Why comment when you don't have even the most basic understanding of the medicine's action?
Here’s what Google says about how Mounjaro works:
Increasing Insulin Secretion: Mounjaro stimulates the pancreas to release more insulin when blood sugar levels are high (after eating), which helps move glucose from the bloodstream into the body’s cells for energy.
Decreasing Glucagon Production: It lowers the amount of glucagon (a hormone that tells the liver to produce and release stored sugar) made by the liver, preventing excess glucose from entering the bloodstream.
Slowing Digestion: The medication slows gastric emptying (how quickly food leaves the stomach), which makes you feel fuller for longer periods and helps prevent sharp blood sugar spikes after meals.
Reducing Appetite and Cravings: It acts on appetite centers in the brain (the hypothalamus) to decrease hunger, reduce cravings, and help manage food intake, contributing to a calorie deficit.
Improving Insulin Sensitivity: Over time, it helps your body become more responsive to its own insulin, which is beneficial for managing type 2 diabetes and reducing fat storage, particularly visceral belly fat.
And if the word “shrinks” offends you, I think it does to some extent because eating less is one of the goals and since the stomach expands as you overeat, it should naturally shrink as you eat less.
