Eating sugar before bed – is it bad?

by | Oct 6, 2022 | Nutrition | 0 comments


When you’re a kid, your parents tell you not to eat sugar before bed. It’s bad for your teeth, they say. But what about now? Does eating sugar before bed impact the quality of your sleep? Is it healthy or harmful? Let’s explore!

What happens to your blood sugar when you eat before bed?

When you eat sugar, it’s converted to glucose. Glucose is stored in the liver and muscles as glycogen. When your body needs energy, glucose is released into the bloodstream. Where it can be used by organs and other tissues.

If you don’t use up all of this glucose. Then it will be converted to fat and stored in your body.

Can eat sugar before bed cause sleeplessness?

That’s the question we’ll be tackling here, so let’s get down to business and find out!

One of the most common misconceptions about eating sugars before bed is that it causes sleeplessness. People who are not accustomed to eating sugars might feel especially drowsy after consuming them. As this can cause a spike in insulin levels. Insulin helps your body store fat, but it also induces drowsiness. This may explain why you feel tired after having a large meal with lots of sugar. However, if you suffer from insomnia because of sugar consumption before bedtime. There are some things you can do to help prevent it:

How to balance it out.

In order to balance out your eating habits, you can:

  • Eat a healthy meal before bed. If you have time to cook at night, make a few servings of something healthy like soup or salad. This will give you the energy and nutrients that your body needs without the sugar crash later on.
  • Avoid eating too much sugar. The American Heart Association recommends that men eat no more than 150 calories from added sugars per day (about 6 teaspoons) and women consume no more than 100 calories per day (about 5 teaspoons). Another way to avoid overdoing it is by sticking with natural sugars such as honey or maple syrup instead of processed white sugar products like cakes or cookies.
  • Avoid eating too late at night. Try not to eat anything right before going to sleep because it may upset your stomach while sleeping and cause indigestion in the morning! Make sure that whatever food item is consumed is digested properly before going off into dreamland; this way there’s less chance of having nightmares about feeling bloated all night long – which will definitely ruin everyone’s fun dreams!

What to do if your sleep is disrupted due to blood sugar.

If you’re having trouble sleeping because of blood sugar, eat a small snack with protein before bed. This will help stabilize your blood glucose levels and keep them from rising too high or dropping too low as you sleep.

If your diet is high in carbohydrates and sugary foods, try eating a bedtime snack that is low in sugar. The ideal bedtime snacks are ones that are high in fiber, protein, and healthy fat; these nutrients help stabilize the body’s insulin response while keeping cravings away during the night when they’re needed most!

Should you avoid eating before bed entirely?

While it may seem like a good idea to avoid eating before bed, this can actually have an adverse effect on your health. If you’re not eating sugary foods before bed, you will have more energy during the day, making it easier for you to exercise and lose weight. In addition, by sleeping better at night and having more energy during the day, there are many positive benefits that come from avoiding eating sugary foods prior to going to sleep.

You’re probably okay, but give it some thought.

If you’re thinking about eating sugar before bed, here are some things to keep in mind:

  • You probably don’t need the extra energy. There are plenty of ways to get that boost throughout the day, so if it’s after lunch and you’re still feeling hungry, try something else.
  • Eating sugar before bed can affect your sleep. You know how some nights you have trouble falling asleep? That could be because you ate a sugary snack right before going to bed. Your blood sugar spikes then crashes when trying to go into sleep mode—and who needs that?
  • It can also cause weight gain! Sugary foods may be tempting when they’re around, but they aren’t always good for us and their effects can last long after we’ve eaten them (or even longer).

Carbohydrates (which include sugar) can cause your blood sugars level to rise.

Carbohydrates are a source of energy for your body. Your brain uses glucose as fuel, so it relies on carbohydrates for survival. Carbohydrates are broken down into glucose in your body and then used as an energy source. Glucose is the main source of energy for your body to function properly—it fuels all activities from chewing food to exercising, so having low levels can have serious consequences on your health and well-being.

The more active you are, the more carbohydrates you need to eat; if you exercise vigorously or play sports regularly, eating too few carbs could be detrimental to your performance and overall health.

Carbohydrates are a source of energy.

Carbohydrates are a source of energy. They breaks down in the body into glucose, which is the body’s preferred source of fuel. Glucose is then used to create ATP—the currency of energy for our bodies.

Your brain uses glucose as fuel.

Brain cells can use glucose, but they’d rather use ketones.

The brain uses glucose as fuel, but it can also utilize ketones for energy. Ketones are made by the liver from fatty acids when blood glucose is low, or when you’re fasting. They’re like a backup fuel source for your brain and nervous system to ensure that you have enough energy to keep going throughout the day when you haven’t eaten recently.

And if brains are capable of burning both types of fuel equally well—glucose and ketones—then why does your body make so much effort to produce glucose in the first place? Because there’s more than one reason why having extra glucose around can be beneficial: not only does it provide energy for every cell in your body but it also helps maintain proper insulin levels so that some cells don’t become resistant (and therefore less able) to insulin’s effects over time

Eating sugars before bed may be connected to weight gain.

Weight gain is a real concern when it comes to eating sugars before bed. The act of digesting food causes your body to produce insulin, and if you’re eating the wrong types of foods at night, that could lead to insulin resistance—a condition where your body becomes less sensitive to insulin and more likely to store fat. Insulin resistance has been linked to diabetes, heart disease, and other health problems.

Additionally—and this is particularly true for children who consume large amounts of sugar throughout the day—consumption of too many sweets before bed can cause tooth decay.

Food is eaten before bed is generally stored as fat rather than burned as energy.

[You] may be thinking, “There’s no way that eating sugar before bed could make me fat.” It’s true that eating sugar at any time of day is not necessarily bad for your weight. However, it does have other effects on the body.

Sugar has a high glycemic index (GI), which means it quickly raises blood sugar levels. It also causes your pancreas to release insulin, which helps move glucose into cells for energy production. When you eat sugars before bedtime, however, they are not burned as energy but stored as fat instead. Food eaten before bed is generally stored as fat rather than burned as energy. This means that if you eat sugary foods late in the day or night and then go to sleep shortly thereafter without exercising or doing anything else physical—like digesting food—the extra calories will likely be converted into additional body fat over time (which can lead to weight gain).


While it’s unlikely that eating sugars before bed will have a negative impact on your sleep, there are some things to keep in mind. For one thing, this type of food is often high in calories and carbohydrates which can cause blood sugar levels to rise throughout the day. If you find yourself waking up feeling groggy or making poor decisions because of low blood sugar during the day (such as skipping meals), then avoiding eating before bed might be something worth trying out!
