What the research found
Commentary (perspective). An npj Aging paper (19 September 2026, doi 10.1038/s41514-026-00503-5) proposes the completion-gap framework: meal-completion drive and physiological energy demand are only partly coupled, so a persistent mismatch can raise weight until a new equilibrium. It is a testable model, not a trial. Educational aging notes, not a diet.
