Is Meal Timing worth prioritizing?

A systematic review and meta-analysis in JAMA Network Open found meal timing is associated with anthropometric and metabolic outcomes independent of total caloric intake, and several randomized controlled trials support this directly: early time-restricted feeding improved 24-hour glucose levels and affected circadian and aging-related biomarkers in one trial, while a separate trial found prolonged, controlled daytime eating (versus delayed, evening-shifted eating) improved weight and metabolic markers even when calorie content was matched between groups. Weighing that against the numbers, Meal Timing is not a priority based on current data — the evidence is only moderate (50/100), and its estimated impact (38/100) is on the lower end too.
