Glucagon receptor signalling in the liver, through cyclic AMP, mobilises stored glycogen and increases gluconeogenesis. This is the hormone's role in maintaining glucose between meals and during fasting, and it is the reason glucagon is used clinically to reverse severe hypoglycaemia.
An agonist at this receptor will, on this pathway alone, raise glucose. That is the conflict the triple-agonist design has to manage.
The same signalling increases fatty-acid oxidation in hepatocytes and suppresses lipogenesis. In animal studies glucagon receptor agonism reduces hepatic triglyceride, and this is the mechanistic rationale cited for the liver-fat findings in the Nature Medicine substudy.
The substudy authors are explicit that their design cannot separate a direct hepatic effect from the consequence of weight loss. The animal mechanism is established; its contribution in people is inferred.
Despite the glucose-raising pathway, glycated haemoglobin fell in the phase 2 diabetes trial and fasting glucose fell in the obesity trial. The incretin components' effect on insulin secretion, and weight loss itself, more than offset glucagon's hepatic glucose effect at the receptor ratios used.
That is the resolution of the paradox for this specific molecule, measured rather than assumed.
