A survey has pinpointed the best times to eat breakfast, lunch and dinner if you want to shed as many pounds as possible. The optimum time to have breakfast is shortly after 7am, with 7.11am picked as ideal. Lunch is best enjoyed earlier rather than later with the key time between 12.30pm and 1pm â 12.38pm being spot on. Dieters say the best time to eat breakfast is 7.11am, the optimum time for lunch is 12.38pm and the best time to eat dinner is 6.14pm. They also say breakfast is the most important meal of the day. Leaving dinner later than 7pm can be ruinous for diets - the best time is between 6pm and 6.30pm, with 6.14pm the best.
