Cortisol Extremely Simplified by Dr Berg

author avatar Dr. Eric Berg 12/03/2023

Have you ever experienced the overwhelming burden of life's demands? It's not just an old saying, and it's natural science.

You know how stress can make you feel tired and worn out. But did you ever think that same stress might also mess with your waistline?

Let me paint a picture for you. Imagine stress as this sneaky little gremlin inside us, cranking up our cortisol levels - our body’s primary “stress hormone.” That's right, folks! When you're under pressure, your adrenal gland pumps out more cortisol than ever.

This isn't just some abstract health jargon, though. High cortisol leads to belly fat accumulation and makes shedding those extra pounds way harder than it should be!

I see I've piqued your interest... Let's not stop here, shall we?

Understanding Cortisol and Its Role in the Body

An outline of cortisol's activities, how it responds to different kinds of stress, and its part in the body will be presented. This section will also explore the adrenal gland's role in cortisol production.

What is Cortisol?

A brief explanation of cortisol, a hormone that responds to different types of stress.

The Adrenal Glands and Cortisol Production

A discussion on the adrenal gland's function in producing cortisol and its lack of an off switch.

The Link Between Stress and Cortisol Levels

When we're stressed, our bodies respond by producing cortisol. This hormone helps us handle stress, but what happens when stress is constant?

Stress Triggers for Cortisol Production

Your body reacts to different types of stressors - physical or mental trauma, poor eating habits, and even hormonal changes. All these can cause a spike in your cortisol levels.

Studies show that chronic stress leads to high cortisol production, which remains elevated over time.

The Accumulation of Stress Over Time

We all face stressful life events like college exams, parenting struggles, or dealing with divorce. These accumulate over time, causing consistent elevation in our cortisol levels.

This long-term exposure to high-stress environments has been linked directly with numerous health issues, including weight gain due to increased appetite and reduced metabolism rates.

Symptoms Indicative of High Cortisol Levels

When cortisol levels soar, your body sends out distress signals. Some might be familiar; others can surprise you.

Common Symptoms of High Cortisol Levels

The telltale signs often mimic other health issues. It's easy to dismiss them as isolated problems when connected by a common thread: high cortisol levels.

Inflammation is one such sign. Your joints may ache, and your skin could break out in rashes or acne. You might even feel constantly tired due to disrupted sleep patterns – another symptom triggered by excessive cortisol.

Studies show cortisol at night should decrease, but stress keeps it revved up, messing with our shut-eye time.

A foggy brain also points towards elevated cortisol, according to research. Tasks that were once second nature suddenly become challenging puzzles - like forgetting where you put the car keys.

  • Cholesterol issues: Bad cholesterol goes up, while good cholesterol takes a nosedive when there's too much cortisol.

  • Gut troubles: Ulcers and irritable bowel syndrome (IBS) are more likely if you have persistently high cortisol.

  • Blood sugar instability: Constantly fluctuating blood sugars? Hello, diabetes.

  • Allergies and asthma: Cortisol compromises immunity, which means allergies flare up and asthma worsens.

The Impact of High Cortisol Levels on Weight Gain

High cortisol levels can be a weighty issue. Excess cortisol production in response to stress can lead to weight gain.

Cortisol's role in our body is like that tricky part of your favorite song - essential yet complex. When stressed, our adrenal glands pump out this hormone, like a concert speaker, at a total volume.

But here's where things get interesting: Cortisol doesn't just manage stress and controls how our bodies use carbohydrates and fats. It triggers processes that convert proteins into energy and releases insulin for maintaining blood sugar levels.

This could sound great if not for one major catch: Excess cortisol can increase appetite and cravings for high-fat foods. That means more donuts than carrots, folks.

To make matters worse, all those extra calories tend to accumulate as belly fat due to increased storage capacity. So, while you may think "stress-eating” gives temporary relief, its long-term effects are less comforting.

How Stress Affects Hormones Related to Weight Management

If you're trying to shed pounds but have persistent stress, it's time to look honestly at the situation. High-stress levels can mess with your hormones and make shedding pounds more challenging than usual.

The Nullifying Effect of Stress on Fat-Burning Hormones

Ever wondered why, despite all the gym hours and strict diets, you don't see results? Well, blame it on cortisol. This sneaky hormone rises when we're stressed out. And here's the kicker: It blocks fat-burning hormones.

Cortisol has an uncanny knack for urging our bodies to store excess fat instead of burning it off (study). Think about that next time stress makes you want to skip the Gym or reach for junk food.

Weirdly enough, this doesn’t happen by accident; our bodies are designed this way. In prehistoric times, storing extra energy as fat during stressful situations was helpful—like running from a saber-toothed tiger. But now? Not so much.

To sum up: If weight loss feels like climbing Everest in flip-flops—it might not be just diet or exercise—you may need help managing stress too.

Intermittent fasting on a notepad

Cortisol and Intermittent Fasting

Intermittent fasting, a popular eating pattern that involves cycles of eating and fasting, has been studied for its potential effects on cortisol levels. Some research suggests intermittent fasting may help regulate cortisol production by promoting stress resilience.

When done correctly, intermittent fasting can enhance the body's ability to manage stress and improve overall hormonal balance.

However, it's important to note that the impact of intermittent fasting on cortisol can vary from person to person, and it's crucial to adopt a fasting schedule that aligns with individual needs and preferences.

If you are considering intermittent fasting as a means of how to lower cortisol, consulting with a healthcare professional or nutritionist for personalized guidance is advisable to ensure it's a safe and suitable approach for your health and well-being.


Remember how stress, that sneaky gremlin, stirs up our cortisol levels? It's no light matter. We've observed the harm it can cause.

Cortisol isn't just a buzzword in health-related conversations; it's an important hormone that responds to various types of tension.

But when those cortisol levels soar sky-high due to accumulated pressure from life events or poor eating habits, they trigger inflammation and other nasty symptoms.

Most crucially, though, is this: High cortisol equals belly fat accumulation and weight loss resistance. Now you know why shedding those extra pounds feels like scaling Mount Everest!

This paints a clear picture of how stress affects cortisol and weight gain. Armed with knowledge now, make your next step count! Remember the link between your mind's well-being and your body’s shape because conquering one means mastering both!
