Optimal metabolic health is crucial when it comes to reducing the risk of serious conditions like heart disease, diabetes, stroke, and Alzheimer’s disease — all of which rank among the top causes of death in the United States.

Low Energy

Glucose, a primary energy source, can cause energy fluctuations when it spikes and crashes. After a blood sugar spike, your body releases insulin, leading to a drop in blood sugar –a condition known as reactive hypoglycemia. Many people experience fatigue and cravings for carbohydrates when this happens.

Trouble Losing Weight

Gaining weight that won’t budge can be an early warning sign of poor metabolic function. Unlike other symptoms of metabolic syndrome, you can observe this one without medical tests.

However, when you gain a lot of weight, shedding even a few pounds can be challenging. That’s because metabolic syndrome often involves insulin resistance, which hampers your body’s ability to burn fat.

Brain Fog

Brain fog can be used to describe mental fogginess, difficulty concentrating, and memory issues, and can be caused by various factors like lack of sleep, stress, depression, and even hormonal changes. Poor metabolic health may also contribute to feeling a bit foggy. Researchers believe that it can occur through two metabolic pathways: glucose dysregulation and neuroinflammation in the brain.

While our brains need glucose for optimal functioning, too much glucose in the bloodstream can impair our cognitive function. A study found that those who consumed more than 14 teaspoons of sugar daily were more than three times more likely to experience cognitive impairment than those who consumed less than 6 teaspoons. Additionally, high glucose spikes have been associated with lower scores on verbal memory tests too. 

Mood Changes


Acne isn’t just an issue you dealt with as a teenager – many adults struggle with it too. Stress, hormonal fluctuations, medications, and a diet that causes glucose spikes can all contribute to adult acne. 

What You Can Do To Improve Your Metabolic Health

If you’re experiencing one or more of the signs above that could indicate poor metabolic health, try following some of these strategies that have been shown to improve overall metabolic fitness.

Regular Exercise: Engage in regular physical activity to control glucose levels and enhance your mood. Moderate exercise, such as 30 minutes, 3-plus times a week, improves insulin resistance and glycemic control. 

Sunlight Exposure: Spend at least an hour outdoors in daylight. Sunlight not only boosts mood by increasing serotonin production but also helps regulate circadian rhythms, affecting food intake, glucose control, and energy expenditure within the metabolic system.
