So you’ve had a busy morning and it’s time for lunch. For many people, work lunches involve buying food from the company cafeteria, or heading out to one of the many eateries that cater to the workweek lunch crowd. Taking your full lunch break is a great way to decompress and prepare for the work in the afternoon (see our blog on how to do the business lunch healthfully), but there is one outcome every productive worker wants to avoid: the food coma.
The “Food Coma” which is so ubiquitous it was added to the Oxford Dictionaries Online in 2014, is that feeling of sleepiness that overtakes people after a big meal. You may know it by a different name like “the itis,” or “after dinner dip,” but you probably haven’t heard of the technical term: “postprandial somnolence.” We most commonly think of it happening after big holiday meals (like Thanksgiving) but a food coma after lunch can ruin afternoon productivity. So how can we all prevent the food coma…
Don’t go too big: A study in young men tested whether a low or high calorie lunch would have a greater impact on sleepiness during a monotonous drive (don’t worry, the drive was in a simulator). Researchers found that the larger meal caused a much greater lull in attentiveness and trend toward greater sleepiness compared to the smaller meal.
Tip: Pack your lunch the night before, or make sure to exercise your ordering skills at a restaurant to ensure your meal is less calorie dense.

Keep those carbohydrates complex: One theory for feeling sleepy after meals has to do with the amount and types of carbohydrates we eat. There is evidence that eating easily digestible simple carbohydrates (like white flour and sugary desserts) causes sleepiness by increasing blood sugar and subsequent insulin production. That increase in insulin production happens concurrently with increases in hormones like melatonin which causes sleepiness, and inhibition of orexin neurons which help maintain wakefulness. Multiple studies show greater sleepiness and earlier onset of sleep with meals higher refined and total carbohydrate. Tip: Try to keep your post-meal surge in blood sugar slow and controlled by choosing healthy, complex forms of carbohydrates like whole grains. Also be sure to include plenty of fruits and vegetables that add healthy fiber and slow the digestion of carbohydrate in the gut.
Avoid high fat meals: A study done in over 700 Australian men found that those who ate diets higher in fat reported experiencing greater daytime sleepiness than those with lower fat intake. Tip: Keep your lunch light on the grease! Heavier, fatty foods like pizza and burgers might just exacerbate your post-meal lull. Also consider the type of fat you eat. Typical fast food often contains lots of saturated fat, the fat we typically consider less healthy. Instead, choose foods full of healthy unsaturated fats like guacamole, or a salad with a vinegar and olive oil, nuts and seeds.
Get a good night’s sleep: The experience of a “afternoon dip” doesn’t have everything to do with your meal. At least some of this post-lunch sleepiness is due to natural fluctuations of your circadian rhythm which can be exacerbated by the content of your meals. However, another major factor for your desire for an afternoon nap? Sleep debt. According to the CDC, 1 in 3 Americans is sleep-deprived and you’re much less likely to feel energized after lunch if you didn’t get enough sleep the previous night. Poor sleep is also associated with poor food choices, which can exacerbate the food coma, creating a vicious cycle… Tip: Set an alarm not just for the morning, but for bedtime and hold yourself to it! Ensuring you get enough sleep will not only help you stake wakeful throughout the workday, but will also help you make healthy food choices at lunch!
It might feel great to take a nap after a satisfying meal, but this isn’t an option when you’re busy at work. Prioritizing healthy, light lunches and adequate sleep at nighttime can help you maintain your productivity and prevent the dreaded food coma.
However, if you’re like many Americans, you have a hectic work day and prioritizing healthful behaviors can be difficult. Check out B.Komplete’s post on how to maintain a healthy lifestyle with a busy schedule!Read More
