Cortisol And Fat Loss

What is Cortisol? How cortisol levels impact your health

If youre familiar with coach Poliquins body composition analysis approach you know the system claims that excess cortisol leads to abdominal fat storage.

But if you remember what the functions of cortisol are, you might see a contradiction here. After all, one of the functions of cortisol is to mobilize stored energy , not store it.

Cortisol is, in fact, a fat loss hormone, at least when produced in a pulsatile manner. But that doesnt mean chronic cortisol cant make it harder to lose fat. While a short-term elevation of cortisol is involved in fat loss, if it becomes chronically elevated it can make the fat loss process harder. How? Two ways

1 Cortisol can decrease the conversion of T4 into T3.

Remember, T3 is the thyroid hormone that has the greatest impact on your metabolic rate. When its higher, your metabolic rate increases so you burn more calories on a daily basis.

If T3 goes down, so does your metabolic rate. So T4 doesnt have as much of a direct impact. The body produces mostly T4 and converts it into T3 at the level deemed safe for survival by the body.

If youre chronically deprived of energy though, the body will reduce the T4 to T3 conversion, decreasing your metabolic rate. During our evolution, when cortisol was elevated chronically, it meant that we werent able to find food and that, as a result, cortisol always had to be high to keep blood sugar stable and mobilize stored energy.

2 It can lead to insulin resistance.

How Is Cortisol Controlled

Blood levels of cortisol vary throughout the day, but generally are higher in the morning when we wake up, and then fall throughout the day. This is called a diurnal rhythm. In people that work at night, this pattern is reversed, so the timing of cortisol release is clearly linked to daily activity patterns. In addition, in response to stress, extra cortisol is released to help the body to respond appropriately.

The secretion of cortisol is mainly controlled by three inter-communicating regions of the body; the hypothalamus in the brain, the pituitary gland and the adrenal gland. This is called the hypothalamicpituitaryadrenal axis. When cortisol levels in the blood are low, a group of cells in a region of the brain called the hypothalamus releases corticotrophin-releasing hormone, which causes the pituitary gland to secrete another hormone, adrenocorticotropic hormone, into the bloodstream. High levels of adrenocorticotropic hormone are detected in the adrenal glands and stimulate the secretion of cortisol, causing blood levels of cortisol to rise. As the cortisol levels rise, they start to block the release of corticotrophin-releasing hormone from the hypothalamus and adrenocorticotropic hormone from the pituitary. As a result, the adrenocorticotropic hormone levels start to drop, which then leads to a drop in cortisol levels. This is called a negative feedback loop.

What Is It Like Living With Cushings Syndrome

Cushings syndrome can be difficult to live with, but your quality of life doesnt have to decrease. There are healthcare providers trained to help you and there are treatments available. With proper procedures and medicine, Cushings syndrome can be cured.

You may find yourself dealing with some emotional and social issues as a result of Cushings syndrome. Some people may feel embarrassed by the balding, excessive hair and/or the weight gain in the face and back of the neck. Moon face and buffalo hump may make you hesitate to participate in social situations. With time, those symptoms can be cured. Cushings syndrome can also cause depression and other mental illnesses. If need be, consult a therapist for counseling and a psychiatrist for medication to help yourself deal with the emotional impact of Cushings syndrome.

How Can I Reduce My Risk Of Or Prevent Cushings Syndrome

You always need cortisol in your body. You need it to function. It manages your respiration, turns your food into energy, regulates your blood sugar, helps you cope with stress and more. Cortisol is not your bodys enemy, but too much of it can be. Have your healthcare provider monitor your cortisol levels closely if youre on glucocorticoids or steroids. Unfortunately, theres no way to prevent a tumor that causes Cushings syndrome.

Stress Hormone Predicts Heart Death

endocrine physiology at University of Pennsylvania

High Cortisol Levels Raise Risk of Heart Disease, Stroke 5-Fold

Sept. 9, 2010 — Doctors have long warned patients that stress is bad for the heart. Now new research provides direct evidence to back up the warning.

In the newly published study, high levels of the stress hormone cortisol in the urine were associated with a dramatic increase in death from cardiovascular disease years later.

Compared to study participants with the lowest cortisol levels, those with the highest levels were five times as likely to die of heart attack, stroke or other cardiovascular causes over six years of follow up.

The association was seen both in people with and without heart disease when they entered the study.

While earlier research suggested a link between high cortisol levels and cardiovascular risk, the study is the first to directly test the hypothesis that elevated stress hormones predict heart disease death, says lead researcher Nicole Vogelzangs, PhD, of VU University Medical Center in the Netherlands.

âWe were actually surprised to find that the association was so strong,â Vogelzangs tells WebMD. âCortisol levels in older adults were clearly predictive of death from cardiovascular causes, but were not predictive of other causes of death.â

The study was published less than a week after a separate team of researchers reported that high levels of the hormone in hair samples predict heart attack risk.

Start Your Shift Today

Personally, I wrote the Adrenal Reset Diet around a clinical trial. We showed that simple, good food, which was properly timed, could radically improve this cortisol cycle.

The idea is that carbohydrates basically push down cortisol. If you use it strategically, you can get your cortisol to where you want it: high in the morning, and lower in the evening.

Some good carbs at breakfast, some at lunch, and a healthy dose in the evening is really all that it takes. Ultimately, it helps to engender a good cortisol curve within your body. In a nutshell, thats the Adrenal Reset Diet19.

Its a simple shift, but it can:

  • Improve your cortisol
  • Cut down your cardiovascular risk
  • Help you sleep better
  • Leave you feeling more energized
  • Provide you with better weight loss results

Bottom Line: At the end of the day, it is all about cutting down our risk while feeling good about our bodies. We have seen our cortisol can be connected to cardiovascular risk, which can sometimes be fatal, but we do have a solution. All you have to do is make some simple changes, and you can be on your way to a better life.

When Should I See My Healthcare Provider

See your healthcare provider if you have the following symptoms of Cushings syndrome:

Symptoms that affect females specifically include:

  • New or excessive facial hair.
  • A change in libido .
  • A change in the menstrual cycle.

Symptoms that affect males and females include:

  • Rapid weight gain in the face , abdomen, the back of the neck and chest.
  • A red, round face.
  • Purple stretch marks over the abdomen.
  • Easy bruising on the arms and legs.
  • General weakness and tiredness .
  • Blurry vision and dizziness.

Effects Of The Stress Intervention Programs On Hrv And Cortisol

When looking at the effects of the programs within the groups, no change in HRV between the three time points was observed in any of the groups. For cortisol, a significant decrease between the fourth and the 8-weeks measurement was found, only in the group that was offered the mechanical massage. When the five study groups were compared with each other, there were no differences in HRV and cortisol between the programs, neither at the three different time points, nor in the effects on HRV and cortisol over time. These results are not in line with our expectation that the mechanical massage, mental training, and the combined program, would be more effective in increasing HRV and decreasing cortisol when compared to both the control and pause group.

High Blood Pressure Symptoms

1 Breathing technique to improve Heart Rate Variability & resistance to stress

Before we get into the details of what conditions affect your blood pressure and what to do about them, here are some high blood pressure symptoms to look out for:

  • Dizziness
  • Bloody urine
  • Edemas/swelling

As you can see, these symptoms can be pretty serious, and thats because they usually come about during a high blood pressure crisis. Thats when your blood pressure is close to or over 180/120 mm Hg. But even 140/90 mm Hg is considered hypertension, with 120/80 mm Hg and up considered at risk . And its usually very difficult to spot blood pressure symptoms for 140/90 mm and up unless it gets to a crisis level.

Still, the underlying causes of hypertension can have their own set of symptoms that you can watch out for. And addressing these causes may save you from having to take blood pressure medication. In fact, regulating your blood pressure is not that hard, and it can make a huge difference to your cardiovascular health and the health of your Cardionomic Circuit.

Laughing And Having Fun

It is hard to feel stressed when having a good time, so finding time to have fun can also lower a persons cortisol levels. One study showed cortisol levels decreasing in response to laughter.

Being happy and having a positive outlook appear to be related to lower cortisol levels, and happiness has other benefits too, such as lower blood pressure and a stronger immune system.

Rewire Your Sleep Schedule

Sleeping in time with your bodys biorhythms and getting enough quality sleep can help you lower your cortisol levels naturally. Ideally, getting to bed by 10PM. will help you avoid a late evening cortisol spike which could make it hard to get to sleep and sleep soundly. This also takes advantage of natural melatonin production, which starts around sunset to get help you wind down.

Research in the Journal of Nursing Research found that shift workers who sleep during the day have higher daytime cortisol and get less sleep per day than people who sleep at night, so if your job allows, its best to adjust your sleep schedule accordingly.

Too Much Cortisol Is The Problem

Cortisol, as we can see, is more than a stress hormone. The trouble occurs when were not in active fight-or-flight mode and cortisol production is still rampant. This constant cortisol release can happen when were always working too hard, dealing with toxic or challenging life situations, or feeling generally overwhelmed with the many facets of modern life. Its especially rampant if we have no way of managing our stress.

We know that chronic stress and elevated cortisol levels can increase ones risk for depression, can make it increasingly difficult to lose weight, and can also perhaps lower life expectancy, Dr. Akhunji says.

As cortisol is controlled by the hypothalamus, the adrenals, and the pituitary gland, doctors and wellness practitioners often refer to something called the HPA axis. When we continually respond to a threat , our brain presses on the cortisol gas pedal and doesnt stop.

Cortisol and Diabetes: Is there a Hormonal Connection?

If you have symptoms of cortisol overload and have a tumor or are taking certain medications , its wise to speak to your doctor right away. But if youre one of the millions of Americans experiencing chronic stress, adopting a stress-reduction routine is also key.

Theres a reason why doctors and wellness practitioners talk so much about stress relief. There are many signs of stress, all of which can affect the quality of your life, your job, your relationships, and your health, including:

  • nightmares
  • experiencing panic attacks
  • dealing with skin problems and mysterious rashes

Get your cortisol under control by engaging in a regular sleep cycle, journaling, or speaking to a therapist about other ways to get a handle on stress. Theres no shame in asking for help.

Dr. Akhunji recommends three simple lifestyle choices for reducing cortisol:

The Cardiovascular System And Adrenal Fatigue

Adrenal Fatigue Syndrome is one of the conditions we look at when someone comes to us with unstable blood pressure, whether low or high. Its the result of facing chronic stress and the subsequent exhaustion of the adrenal glands. The adrenals have to overwork to produce cortisol and other stress hormones to fight that stress. But if the stress is chronic, they can get so overworked that they dysregulate.

Symptoms of AFS include fatigue, sleep problems, weight gain, difficulty losing weight, brain fog, anxiety, mild depression, hair loss, dry skin, loss of libido, PMS, infertility, hypoglycemia, salt and sugar cravings, lowered immunity, food and drug sensitivities, estrogen dominance, unstable blood pressure, heart palpitations, cardiac arrhythmia, POTS-like symptoms, and atrial fibrillation.

The last few symptoms are, in fact, due to how dysregulated adrenals affect the NEMs Cardionomic Circuit. As the adrenals start to produce either too much or too little stress hormones, that has an impact on the cardiovascular system in several ways. And it also affects the nervous system, including the ANS, which is what controls things like blood vessel constriction and heart rate.

But even then, there is a high likelihood that these two components will become dysfunctional as they face the same stress that took out your adrenals. Lets take a closer look at how this progression affects your blood pressure.

Become Aware Of Your Negative Thoughts

Thinking negative or worried thoughts about the future causes an immediate rise in cortisol. If you have a constant negative internal dialogue going, youll have higher cortisol responses to stress.

Wellbeing and mental health affect physical health. You can address elevated cortisol levels by becoming aware of negative thoughts and putting them into perspective.

Timing Of Ptsd Assessment

Resilience in the face of trauma is the norm; however, posttraumatic symptoms are commonly reported by individuals during the first several months of recovery. In one study of rape survivors, threshold criteria for PTSD were already present in 94% of women after two weeks, but only 64% after five weeks, and 47% after 11 weeks . If aberrant stress responses following trauma distinguish vulnerable from resilient individuals, clearer associations between risk markers and PTSD symptoms may emerge over time as resilient individuals recover. We examined whether the timing of PTSD assessments influenced the strength or direction of relations between acute stress responses to trauma and subsequent PTSD symptoms. We hypothesized that effect sizes would be larger for PTSD assessments that occurred after longer lags from the focal traumatic event.

Cortisol Rapidly Increases Baroreflex Sensitivity Of Heart Rate Control But Does Not Affect Cardiac Modulation Of Startle


We investigated if cortisol affects processing of cardio-afferent signals at brainstem level.

The cardiac modulation of startle may reflect baro-afferent signal transmission.

Baroreflex sensitivity incorporates afferent, central and efferent components.

Intravenous administration of 1;mg of cortisol rapidly increases BRS, but not CMS.

We conclude that cortisol rapidly affects central or efferent processing of baro-afferent signals.

Cortisol And Our Fight Or Flight Response

In addition to helping manage some of your bodys basic functions, cortisol is linked to your stress response as well. So what is cortisol doing when you encounter a stressful situation?

One of the chief functions of cortisol is to prepare the body during stressful situationsa fight or flight moment. When you feel threatened, the adrenal glands start pumping out cortisol, causing your muscles to tense and your breathing and heart rates to increase. All of this happens faster than your brain can fully comprehend a situation, allowing you to, for example, jump out of the way of an oncoming car.

If you need to flee a life-threatening situation, rising levels of cortisol in your bloodstream will help you escape. If you need to stay and fight off a threat, your bodys response to the flood of hormones will help give you strength and energy for the conflict.

Unfortunately, the stress response and a boost in cortisol levels can occur in a traffic jam and many other stressful, but certainly not life-threatening situations. Chronic stress, experienced by people living in uncomfortable surroundings, working in jobs they dont like, or staying in unhealthy relationships, for example, can experience additional negative consequences caused by constantly elevated levels of cortisol.

Chronic Stress And Cortisol

Unfortunately, if you live a fast-paced modern lifestyle without proper stress management, your body can stay in more-or-less constant fight-or-flight mode.

Chronic stress throws off your cortisol rhythm, resulting in either high or low cortisol levels.

And both can wreak havoc on your blood sugar, cause high blood pressure, compromise immune function, disrupt sleep, and impact other vital aspects of your health including mental health.

High chronic stress levels have also been linked in studies to cortisol dysregulation.

Dysregulation means your daily cortisol rhythms are broken: instead of a high spike in the morning, you may have a flat curve, or a cortisol spike at inappropriate times .

Cortisol dysregulation from chronic stress is associated with higher risk of type 2 diabetes, depression, high blood pressure, and other health problems.

Another type of dysregulation occurs when your cortisol feedback loop becomes compromised, allowing cortisol levels to rise inappropriately and stay elevated well after you experience stress. Cortisol feedback loop degradation is associated with chronic pain problems, as well as anxiety.
