Pros of Eating Before Bed

Pros to eating before bed include weight loss, sleeping better, and maintaining blood sugar levels.

Weight Loss

Even in sleep, your body needs energy to function, as it’s recovering from the previous day. When you go to bed hungry, your body lacks the calories it needs to recharge; this results in your body holding onto carbs and fats instead of using it as fuel. Choosing sleep-inducing snacks high in tryptophan and melatonin are not only good for you, but they’ll also satiate hunger pangs and give your body the energy it needs to recover at night.


Tryptophan is an amino acid that increases serotonin and melatonin levels in the body. We can’t produce tryptophan naturally—instead, we consume foods that contain tryptophan to induce sleep.

Tryptophan-rich foods include milk, cheese, eggs, nuts, fish, and beans.


Melatonin is a hormone that regulates sleep by influencing the body’s sleep-wake cycle. Melatonin production relies on the body’s exposure to lightless light produces more melatonin.

Good sources of melatonin include cherries, walnuts, bananas, oats, and tomatoes.

Sleep Better

A full stomach makes a person feel sleepy, but foods with nutritional value can make all the difference between a good night’s sleep and indigestion. Healthy snacks like apples and peanut butter or avocado toast contain excellent nutrients.

Maintain Blood Sugar

Foods like fruits, nuts, oatmeal, and whole wheat bread regulate blood sugar levels. Low levels result in less energy and feeling groggy the next morning. High levels cause boosts of energy, increasing sleep disruptions.

Cons of Eating Before Bed

Cons to eating before bed include poor sleep, slower metabolism, eating more, unhealthy choices, acid reflux, indigestion, and heartburn, and health risks.

Poor Sleep

Depending on what you eat and at what time of day, the foods you consume can disrupt your sleep patterns. Foods containing caffeine like chocolate and coffee may seem like a good idea before bed, but the caffeine boosts your energy and may cause you to wake up several times in the middle of the night.

Slower Metabolism

Eating before bed can cause the body’s metabolism to slow. The body slows down its functions at night to prepare for sleep, but consuming foods, especially those high in carbs, can make it harder to digest and result in weight gain.

Meal Size

People tend to be hungriest at night, leading to consuming larger meals. Instead of eating late at night and leaving less time for digestion, try to train yourself to eat larger meals during the day. The phrase, “Eat breakfast like a king, lunch like a prince, and dinner like a pauper” is sound advice to follow, especially if you’re trying to lose weight.

Unhealthy Choices

One of the main issues with late-night snacking is the choices we make—we’re more likely to give in to those cravings for high-fat, sugary junk food like chips, pizza, cookies, and ice cream. When we snack on these types of foods, especially in front of the TV, we’re more likely to binge-eat, or mindlessly eat our way through more food.

Acid Reflux, Indigestion, and Heartburn

Another risk of eating large meals right before bed is acid reflux, indigestion, and heartburn. Giving the body time to digest before bed can reduce the risk of developing these problems.

After eating and climbing into bed, the body rests at a horizontal angle, resulting in stomach acid easily entering the esophagus and causing acid reflux.

Indigestion is when you suffer stomach pains and discomfort after eating a large meal.

Heartburn is a burning sensation in the chest caused by overeating and consuming spicy foods. Heartburn can worsen when lying down.

Worsens Sleep Apnea

Health Risks

Health risks of regularly eating late at night include obesity, diabetes, and heart disease.

Obesity and Weight Gain

Don’t Go to Bed Hungry

Should You Eat Late Before Bed? Pros and Cons - Amerisleep (3)While we encourage you to avoid late-night snacking, we also discourage you from going to bed while hungry. Your body constantly needs energy to function, even during sleep.

Going to bed without a last meal means your body has less energy to rejuvenate and repair itself. Plus, with less energy, the body holds onto existing fat for energy, making it harder to lose weight and easier for weight gain to occur.

Eating your last meal a couple of hours before bed helps you balance the need to avoid any hunger that distracts you from sleep, but also keeps you from feeling uncomfortably full and bloated as you stretch out on the bed.

Healthy Snacking for Better Sleep

These types of foods can also hamper the body’s ability to fall asleep quickly at night— reflux and indigestion, and consuming peppers heat the body and hamper the body’s natural cooling process at night.

Instead, have a bedtime snack containing complex carbs and small amounts of high protein—fruits, veggies, and other nighttimes snacks include:

  • Cheese and crackers
  • Apples and peanut butter
  • Low-sugar cereal with low-fat milk
  • Avocado toast

Foods to Avoid at Bedtime

Should You Eat Late Before Bed? Pros and Cons - Amerisleep (5)Acidic foods, fried foods, spicy foods, and foods high in fat can all be hard on the stomach, particularly if you lie down soon after consumption. Sugary foods can also affect how well you sleep at night, so try to cut out sweets and junk food.

Caffeine is one big no-no when bedtime draws near. Obviously, this means avoiding coffee, caffeinated sodas, and stronger black and green teas. But even decaf tea has trace amounts of caffeine in it, so if you want to go completely caffeine free, we recommend herbal teas for sleep.
