When it comes to our daily habits, it may not surprise you to learn that our genetics play a pretty large role in what we eat. However, did you know that genetics can also influence when we eat?
Most of the time, we assume that our habits and other environmental factors play the largest role in meal timing. Some cultures also have specific meal timings unique to the region. For example, most dinners in Italy are eaten between 8:00 pm and 10:00 pm, while in Norway, dinner time is between 4:00 pm and 5:00 pm.
The timing of when we eat affects everything from energy regulation and insulin production to the ability to manage a healthy body weight.
Today, we’ll talk about how genetics impact meal timings, and how you can figure out the best time to eat breakfast or other meals based on your unique genetic profile.
What our Genetics Tell Us About Meal Timing
It may surprise you to learn that genetics actually play a large role in determining when we eat.
There have been multiple studies done in the last several years that have tried to learn more about the role genetics play in meal timing. Additionally, scientists have probed whether there are certain genetic variants that can be linked to a preference for specific breakfast timings - most particularly, a desire to eat breakfast later in the day.
In one study done on a small group of Spanish twin pairs, researchers found that genetic influences accounted for a “significant proportion of the variability of food timing, particularly breakfast.”
They concluded that since the best time to eat breakfast is influenced so much more strongly by our DNA, it’s probably best to focus on lunch and dinner times if you’re looking to make positive changes related to health or weight loss.
What’s the Best Time to Eat Breakfast?
While the timing of our hunger first thing in the morning may be influenced by our genetics, there are still objectively ideal times to eat breakfast.
There’s a reason why most people consider breakfast the most important meal of the day. Consuming a healthy breakfast is related to a greater intake of nutrients over the day as a whole. It’s also been shown to offer better coverage of nutritional recommendations, and better body weight control.
Most dietitians agree that regardless of when you eat lunch, you should always aim to eat breakfast no less than 2 hours after you wake up. However, as long as you follow those guidelines, the best time to eat breakfast depends on the individual. It should typically be eaten 4-5 hours before lunch. If you regularly eat lunch at 1:00 pm, you should aim to eat breakfast around 8:00 am, or no later than 9:00 am.
If you have to go more than 4-5 hours between meals, try to eat a healthy snack in between. A small handful of almonds, cut-up veggies, or even some whole-grain toast with peanut butter or avocado are all great choices.
