UPDATE: As Thanksgiving approaches on November 23, 2023, experts are weighing in on the best time to serve dinner, emphasizing that early meals may help avoid post-feast fatigue. Families across America are finalizing their dinner menus and pondering a crucial question: When should Thanksgiving dinner be served?

The traditional timing varies, with many families opting for a 3 PM meal, while others stick to a more conventional 6 PM or 7 PM. However, the drowsiness often associated with indulging in a large turkey dinner could be influenced by the timing of the meal.

Research from the Icahn School of Medicine at Mount Sinai highlights that turkey contains tryptophan, an amino acid linked to sleep regulation. Yet, experts like California-based chef Brendan Collins suggest that it’s not just the turkey causing lethargy. “The truth is that we can end up overeating on Thanksgiving, and we get food comas,” Collins stated.

Chef John Carpenter from the Signature Restaurant at La Cantera Resort and Spa in Texas agrees, noting that the combination of heavy foods, alcohol, and the festive atmosphere contributes to post-meal drowsiness. “Thanksgiving dinner is quite heavy,” he explained, mentioning that foods like pumpkin pie and wine also play a role in how we feel afterward.

With this in mind, chefs are urging families to consider an earlier dinner. Carpenter recommends serving the meal in the early afternoon. “Normal family routines can benefit from an earlier meal,” he says. This allows families with children to unwind after eating and enjoy the rest of the day together.

Collins suggests that families should give themselves ample preparation time, ideally two and a half to three hours for cooking. He also notes that if children are present, serving dinner around 2 PM or 3 PM could be more suitable, while adults might prefer a 4 PM or 5 PM dinner.

Notably, a 2022 study published in the peer-reviewed journal Cell Metabolism found that late-night meals can disrupt energy regulation, further supporting the idea of dining earlier during Thanksgiving. “You shouldn’t be eating a huge meal later at night, especially the size of a normal Thanksgiving meal,” Collins added.

As families finalize their Thanksgiving plans, it’s vital not to let the timing stress overshadow the celebration. “Don’t stress out too much about the food,” Collins advises. Thanksgiving is about gathering with loved ones, enjoying quality time, and, of course, indulging in delicious food and drink.

As you prepare for this festive day, remember that the timing of your Thanksgiving dinner could influence not just your enjoyment but also your energy levels throughout the celebration. Share this article to help friends and family make the most of their Thanksgiving experience!
