Lunch plays a key role in fueling your afternoon energy, stabilizing blood sugar and supporting your overall health. Meal timing studies often focus on breakfast and dinner, but studies on lunch timing points are in a clear direction.
You’ve probably heard the analogy that your body is like a car and food is the fuel that keeps it running. So think of your day like a long road trip. Breakfast is the fuel you start, but at some point in your journey you need to get more gas. Lunch is a replenishment that keeps your body and brain working with peak performance. Without it, or without a poorly timed lunch, you are likely to run with smoke, leading to energy collisions, cravings, and even metabolism.
Research suggests that eating too much lunch can have a negative impact on blood glucose control, insulin sensitivity, and weight management. At the same time, eating too early can make you feel greedy later in the day, increasing the chances of overeating. Below we’ll break down the best time to eat lunch and what happens when it’s too early or too late. They also share practical strategies for developing healthy lunch habits.
What is the best time to eat lunch?
From a metabolic perspective, the best time to eat lunch is around 12:30pm. This is consistent with studies showing that eating early in the day supports better metabolic health. This increases the risk of preperturbation and type 2 diabetes if there is a disorder.
One small study At mealtime, pushing lunch later until 2pm suggested that blood sugar spikes increased, increased insulin resistance and increased variability in glucose levels over the next 24 hours. Over time, these changes may increase your risk of developing pre-diabetes and type 2 diabetes.
From a practical standpoint, it makes sense to have lunch around 12:30pm. This is about 4 hours after the optimal breakfast time (before 8:30am). This timing coincides with natural hunger cues, and with a nutritious noon diet, you will feel more energy, be more productive, and reduce the chances of being too hungry.
That said, being flexible with yourself can help. If your schedule does not allow lunch at 12:30pm, aim for consistent times each day and avoid delaying lunch in the afternoon if possible.
The disadvantage of poor lunch timing
Eating early and too late can cause challenges in metabolism and appetite regulation.
Eating lunch early may make you feel hungry later in the day, for example, before 11am, especially if breakfast is early but light. This can lead to excessive snacks in the afternoon, increasing your overall calorie intake and leading to weight gain. Eating too much lunch has a similar effect as it creates long windows with no food.
Plus, pushing lunch too late, such as after 3pm, can have metabolic consequences. Studies suggest that delaying meals past this point can lead to higher post-lactic sugar levels and lower insulin sensitivity compared to dieting early in the day.
Plus, dinner may be late as you are late for lunch. This can destroy the quality of your sleep if your last meal is too close to bedtime.
If late lunch is inevitable, it’s best to try lunch before 3pm. Having a snack in the morning will help prevent extreme hunger.
Does the timing of lunch affect weight loss?
Total calorie intake is a major factor in weight loss, but eating these calories can also make a difference. (And of course there are other factors like genetics, age, build, etc.) Research shows that eating more calories earlier in the day may support weight loss compared to eating the same calories.
1 study We compared two groups of healthy, overweight, and obese women. One consumed a big meal for lunch and a small dinner, the other had a bigger dinner and a small lunch. Both groups were eating at a calorie deficit, but those who ate more at lunch lost more weight.
Eat late lunch It can slow your metabolism and you may get the metabolic boost you get when digesting food, making it more difficult to lose weight.
There are also behavioral elements of lunch timing related to weight loss. If there is a big gap between meals, whether it’s because you eat too early or late, you’re likely to be very hungry, making mindful choices difficult. This allows you to set up to burn more food (and calories) than you intended, and to promote calorie surplus and weight gain.
