Sugar and the Brain. Spring Glucose, a form of sugar, is the primary source of energy for every cell in the body. Because the brain is so rich in nerve cells, or neurons, it is the most energy-demanding organ, using one-half of all the sugar energy in the body.

Without intervention, high blood sugar can lead to severe health problems. In some cases, it can become life threatening. Insulin and glucagon help manage blood sugar levels. In addition to diabetes, possible causes of high blood sugar include :. People with high blood sugar may not notice symptoms until complications appear.

If symptoms occur, they include :. Over time, high blood sugar may lead to :. Hypoglycemia is most likely to affect people with diabetes if they take their diabetes medication — such as insulin or glipizide — without eating.

But, it can happen for other reasons, for example:. The symptoms of low blood sugar include :. Without treatment, low blood sugar can lead to seizures or loss of consciousness.

What are the different types of diabetes? Insulin helps the cells absorb glucose from the blood, while glucagon triggers a release of glucose from the liver. People with type 1 diabetes need to take supplemental insulin to prevent their blood sugar levels from becoming too high.

In some cases, a doctor will recommend insulin for people with type 2 diabetes. However, diet and exercise are usually the first recommendations for this type. Very low blood sugar can become life threatening without medical intervention.

In this article, we look at nine ways to lower high insulin levels. This can be achieved through diet, lifestyle changes, supplements, and medication. A person can manage their diabetes by making healthful changes to their diet, exercising frequently, and regularly taking the necessary medications….

Metabolic flexibility means that your body can switch easily between burning glucose and fat, which means you have better energy and endurance.

Dominic D'Agostino, PhD. Written By The Levels Team. Article highlights Fatigue, decreased energy, and reduced alertness are associated with glucose swings big spikes and dips and elevated fasting glucose. Individuals seeking stable, high energy levels should strive for stable glucose levels in a healthy, normal range.

Continuous glucose monitoring CGM can help people discover how their glucose levels relate to their energy levels, and how to take steps to get glucose under better control. How to get more energy by controlling your glucose levels Sometimes, the quest for more energy may require a fundamental psychological shift in how you view food.

You have a few options at your disposal: Reduce your carbohydrate intake per meal. Every human body is unique, and we all respond to carbohydrates differently. Testing your response to carbohydrates can help you zero in on how much they raise your glucose.

Change your carbohydrates per meal. Within the same vein of our metabolic uniqueness, we also respond to different types of carbohydrates differently.

Try out other metabolic health strategies , like optimizing sleep and engaging in regular exercise, to control glucose levels. Get updates, new articles, exclusive discounts, and more.

So while glucose is indeed a source of energy, flooding our body with too much of it at once appears to take away from energy, rather than contribute to it. The consequent large drop in glucose after a spike will then cause you to feel lethargic, moody, and unfocused.

Many people ride these energy tidal waves all day long. A rapid change in the amount of energy provided to our cells is not a great way to sustain mental focus and performance throughout the day.

Glycemic variability is intricately linked to our brain function and therefore, plays a key role in our energy. Maintaining energy homeostasis appears to rely extensively on our ability to regulate glucose levels within a normal range and avoid high glucose variability.

Again, the brain plays a critical role here and seems to perform best when glucose levels are somewhat stable. Our brain is the primary sensor of glucose levels in the body — responding to changes in glucose by controlling whole-body energy production and metabolism.

In addition, high glucose variability stresses the sympathetic nervous system, which also plays a key role in energy production. On the other hand, less variable glucose levels that are characteristic of a healthy metabolism provide sustained energy to the brain and body.

However, glycemic variability has been linked to central nervous system CNS oxidative stress and inflammation. It is important to remember that glucose levels can rise after eating a meal, but an abnormally large rise in glucose is something to be avoided.

When glucose rises too high, some people can experience jitters, anxiety, a rapid heartbeat, and have a hard time focusing on work and other tasks. Frequent periods of high blood glucose can place stress on the brain and energy production.

But glucose is also necessary for optimal mental energy and performance, and in the absence of hyperglycemia, glucose helps to improve attention and memory. Challenging mental and physical tasks require us to use a lot of glucose, and providing the body with the energy to perform is important.

Consuming glucose can increase energy levels in the brain and improve cognitive performance and memory. Consuming carbohydrates — and by proxy elevating blood glucose — is also well-evidenced to improve physical energy and high-intensity exercise performance.

From this, we can conclude that abnormally high blood glucose, otherwise known as hyperglycemia, seems to reduce energy in the short term. However, maintaining stable blood glucose levels, with normal moderate rises in response to meals and other daily events, is essential for maintaining our energy levels.

Small increases in glucose likely provide us with energy and help supply fuel for the brain and the body. Just as there are energetic risks of letting glucose get too high, letting glucose dip too low can also adversely affect our energy levels.

Though this condition occurs frequently in people with diabetes, it can occasionally happen in non-diabetic people. A sharp rise in blood glucose will cause a subsequent rise in insulin, which works to bring glucose levels back down to normal.

But too much insulin released too quickly can cause hypoglycemia. Hypoglycemia is a situation where the brain is deprived of energy, and this affects energy levels throughout the body. Worsened vision, confusion, lethargy, shakiness, sweating, and trouble concentrating are all symptoms of hypoglycemia.

Mood changes are also common during an episode of low blood glucose. A lot of the research on hypoglycemia has been conducted in people with diabetes. But hypoglycemia significantly impairs brain metabolism, and even short-term reductions in blood glucose decrease simple brain functions and the activation of several brain areas while performing certain cognitive tasks.

Though hypoglycemia may be rare among people with normal glucose metabolism, we can all experience dips in blood glucose that impact our energy levels throughout the day. Even milder drops in glucose can leave us with a feeling of brain fog, fatigue, and a lack of motivation.

Remember that when energy levels are low, our resources will be directed to the brain first — starving the rest of the body of energy. The strategy to prevent large dips in glucose is to first prevent large rises. A glycemic excursion in one direction often precipitates an excursion in the opposite direction, and limiting variability is the key to limiting this roller coaster ride of energy.

Perhaps the best way to limit large rises and falls in glucose is to consume low-glycemic index meals, limit refined carbs, or balance carbohydrate intake with exercise.

However, dietary strategies that are successful for controlling blood glucose will vary widely among all of us. The knowledge of how glucose and glucose variability affect your daily energy levels is important, but so is taking action.

Mapping your energy levels to your blood glucose can allow you to make changes to your diet, exercise routine, or work habits that will allow you to hit peak energy when it matters.

If you want to time your normal daily peak in glucose and energy with your workout or most cognitively-demanding task of the day, pairing your blood glucose readings with an app like Basis is the first step.

Diet quality, exercise, stress management, and adequate sleep are all variables that impact our blood glucose and the variations in glucose throughout the day. This goes to show that, while glucose is important, we have to consider every aspect of our life when thinking about energy management.

We put a lot of effort and research behind our posts and the Basis platform they are a true labor of love.
