The mechanistic explanation is not speculative: the glucagon receptor adds hepatic fatty-acid oxidation, adipose lipolysis and thermogenic energy expenditure that dual agonism cannot engage by design 27, and the Phase 2a MASLD readouts 8590% liver-fat reduction is a direct signature of that pathway 3
