Reading the retatrutide phase 2 data properly rather than the headline, and the 24% figure is doing a lot of work that the confidence interval does not support as firmly as people think.
For anyone tracking the class: GLP-1 alone gets you appetite, GLP-1 plus GIP adds tolerability and lipid handling, and adding glucagon adds expenditure and liver-fat reduction. Each addition also adds a receptor system that can generate side effects.
So the question, as narrowly as I can put it: why adding glucagon agonism to an anti-obesity drug is not self-defeating, given that glucagon raises blood glucose.
I have searched first, so if this is covered somewhere point me at it and I will read it.
Answering the narrow version, because the broad one does not have a single answer. The distinction that resolves most of these threads is between what is true on average and what is true for one person. Both are real; they answer different questions and get quoted as if they were the same one.
I would rather be corrected than agreed with, if it comes to it.

No disagreement with TrialTracker_MD. One condition attached. The glucagon component looks paradoxical and is not. Glucagon receptor agonism raises energy expenditure and drives hepatic fatty-acid oxidation, and its hyperglycaemic tendency is offset by the GLP-1 arm's insulin secretagogue effect. Net result: intake down from GLP-1/GIP, expenditure up from glucagon, glycaemia neutral or improved. It is a balancing act, and it is why the liver-fat results are the most interesting part of the dataset.

Can confirm. Same sequence, different timescale. I had assumed I was the exception until I read this.
From the other side of the consultation, briefly. The version of this that has an answer is narrower than the version being asked. Narrow it and it becomes tractable; leave it broad and the thread will produce nine confident and incompatible replies.
