This Lancet Series paper lays out the core thesis that ultra-processed foods (UPFs)—defined not just by ingredients but by industrial processing itself—drive obesity, metabolic disease, and other health harms through pathways that cannot be explained by calories, sugar, fat, or additives alone. The authors synthesize epidemiology, mechanistic data, and clinical findings to argue that UPFs alter appetite control, disrupt gut and hormonal signaling, and promote overconsumption through hyper-palatability, texture engineering, and rapid digestibility.
The paper positions UPFs as a major, independent driver of global chronic illness and proposes that reducing exposure is essential for improving population health.
