BBC World Service Backs 3-Hour Dinner Gap Before Sleep as 20-Adult Trial Flags Late-Eating Risks

Summary
About three hours before bedtime is the practical target BBC World Service highlighted, saying no single clock time is ideal but a consistent gap before sleep best fits the evidence.
Two small controlled studies drove that advice: a 20-adult lab trial found a 10 p.m. dinner raised post-meal glucose and reduced fat burning versus 6 p.m., while a 16-person trial linked later identical meals to more hunger and lower waking energy use.
Late meals are not treated as catastrophic one-offs, but the program said dinners forced close to bedtime should be smaller and simpler, with a short light walk potentially helping glucose control.
Meal timing still does not outweigh meal quality or daily life constraints: experts pointed to minimally processed, fiber-rich dinners, regular schedules, and cultural routines that make a sustainable eating pattern more realistic.
