Cortisol Increases Glucose Availability

---

The human “fight” or “flight” mechanism served our ancestors well, as the release of steroid cortisol hormone helped early humans survive by increasing blood sugar availability for energy and boosting heart rate to deliver oxygen and nutrients to vital organs and muscles when facing an immediate threat. It naturally stimulates fat and carbohydrate metabolism to create bursts of energy, a mechanism that was vital for survival in more dangerous times.

Unfortunately, in today’s modern world, chronic stress can lead to persistently elevated cortisol levels, which can disrupt metabolism and lead to unwanted weight gain, particularly around the abdomen. After all, when you consume a lot of comfort foods under stress, the excess energy is not burned off by fighting or fleeing. Instead, cortisol hormone influences how this energy gets converted into triglycerides and stored in various fat cells.

This creates a challenging cycle of metabolic disruption, fat accumulation, and potential health complications. But, by understanding cortisol's role, you can take proactive steps to manage stress, protect your metabolic health, and maintain a healthy weight. The key to managing cortisol lies in adopting healthy lifestyle habits. Incorporating relaxation techniques like meditation and deep breathing, maintaining a balanced diet, and getting regular exercise can help lower stress and keep cortisol levels in check.

Excess stress hormone increases fat deposits?

Ever wondered why stress seems to pack on pounds around your midsection? The culprit is a steroid hormone called cortisol and its troublesome relationship that favors storage of less-visible visceral fat. These deposits are stored as deep belly fat that wraps around critical internal organs. Unlike more common deposits of subcutaneous fat, with visceral fat deposits, you cannot “pinch an inch.” Although both types of fat serve important functions, too much creates health risks.

Visceral vs Subcutaneous Fat: The difference in danger of health risks between visceral fat and subcutaneous fat stems primarily from metabolic activity as well as the substances released. Excess visceral fat is more metabolically active and can release free fatty acids and other fat metabolites directly into the liver’s portal system. This can impair hepatic function, lead to fatty liver disease, and cause poor regulation of glucose and insulin metabolism.

What makes the end results of chronic stress worse is that visceral fat contains high concentrations of enzymes that convert inactive cortisone into active cortisol. This means the more visceral fat the body has, the more cortisol that gets produced and released to create a recurring vicious cycle that's hard to break. This can result in the storage of stubborn cortisol-belly fat that has been linked to cardiovascular disease and obesity.

How Cortisol Affects Fat Storage

Fat storage isn’t just a cosmetic issue. Cortisol promotes the activity of an enzyme called lipoprotein lipase, which increases fat storage, particularly in the abdominal region. Unlike regular subcutaneous fat that sits just beneath your skin, elevated cortisol levels encourage your body to store visceral fat specifically around your internal organs. Rather than breaking down stored fat (which cortisol can do when insulin levels are low), chronic stress tips the balance toward increased fat accumulation instead of fat breakdown.

• Increased Food Cravings – Intense cravings for comfort foods isn’t about a lack of willpower, cortisol hormone triggers key biological responses to stress. Unfortunately, this creates a problematic cycle of overeating.
• Cortisol Production in Tissues – When cortisol levels remain elevated due to chronic stress, your body preferentially stores fat in the abdominal region as visceral fat, which can lead newly created fat tissues.
• Excess Glucose Due to Insulin Resistance – Research shows that elevated cortisol is closely linked to several metabolic risk factors, including insulin resistance that is known contributor to abdominal obesity and fat gain.
• Sleep and Hormonal Imbalances – Hormonal imbalances can make it difficult to stay asleep and the disruption doesn’t just cause fatigue, it sets off a chain reaction that can affect other crucial hormones.
• Visceral Fat Accumulation – The higher concentration of cortisol receptors makes visceral fat exceptionally responsive to signals from the steroid hormone, which often leads to increased deposits of belly fat.

Keeping cortisol levels in check is vital not just for weight maintenance, but for reducing your risk of serious health conditions. Understanding how cortisol functions within your body empowers you to take actionable steps toward reducing chronic stress and its harmful effects. By adopting stress management techniques, improving dietary habits, and maintaining an active lifestyle, you can minimize cortisol's negative impact on your body and promote long-term metabolic health.

Adult Women and Men Handle Cortisol Differently

Stress impacts men and women differently, especially when it comes to cortisol, the body’s primary stress hormone, and its role in fat storage. Cortisol influences energy metabolism and fat distribution, but hormonal and physiological differences mean that men and women experience unique patterns of weight gain. Storage patterns are largely influenced by sex hormones, like estrogen and testosterone, but other hormonal shifts occur with aging.

For men, elevated cortisol levels are often linked to the accumulation of visceral fat, or belly fat, which surrounds internal organs and increases the risk of chronic health problems such as heart disease and diabetes. This results in the classic "apple-shaped" or "beer belly" appearance. On the other hand, women prior to menopause typically store fat subcutaneously in areas like the hips, thighs, and buttocks, creating a "pear-shaped" distribution.

Behavioral coping mechanisms for managing stress also differ by gender. Research suggests women are more likely to turn to comfort foods high in sugar and fat, which can exacerbate stress-induced overeating and weight gain. By contrast, men may rely on more harmful habits like smoking or drinking to deal with stress, which carry their own health risks. While these physiological responses to cortisol are distinct, they highlight the importance of understanding how stress management should be tailored for men and women.
