We've all read it. Cortisol is bad for you, and can suppress your hard earned gains. But is this actually true? The answer is yes and no. Cortisol is a very important hormone that you must understand if you want to get maximum results from your training and nutrition programs.
What is cortisol?
Cortisol is a hormone produced by your adrenal glands. It falls into a category of hormones known as “glucocorticoids”, referring to their ability to increase blood glucose levels. Cortisol is the primary glucocorticoid.
Why does your body produce cortisol?
Cortisol is a stress hormone. Your body produces cortisol in response to stress, physical, mental or emotional. This can include extremely low calorie diets, intense training, high volume training, lack of quality sleep as well as common daily stresses such as job pressures, fights with your spouse or being caught in a traffic jam. Trauma, injury and surgery are also major stressors to the body (Note: much of the research done on cortisol and stress has been done on recovering patients, and such findings may not carry over to healthy, athletic populations).
What does cortisol do?
Cortisol is part of the fight or flight response. Faced with a “life or death” situation, cortisol increases the flow of glucose (as well as protein and fat) out of your tissues and into the bloodstream in order to increase energy and physical readiness to handle the stressful situation or threat.
How do you know your cortisol levels are high?
You can get your cortisol levels tested if you choose to. The most common method of testing is a blood test (blood cortisol levels). Saliva and 24 hour urine tests are also available.
What is a normal level of cortisol?
Cortisol levels are higher in adults than children and levels fluctuate throughout each 24 hour period, so tests must account for the time of day. Cortisol concentrations are highest in the early morning around 6 – 8 a.m. and they are also elevated after exercise (a normal part of your body’s response to exercise). The lowest levels are usually around midnight. According to the Medline Encyclopedia, normal levels of cortisol in the bloodstream at 8:00 a.m. are 6-23 mcg/dl.
Should you get your cortisol levels tested?
For serious competitive athletes, it may be worth the time, expense and inconvenience to have cortisol tests done on a regular basis. Some strength and conditioning coaches insist on it. For the average trainee, as long as you are aware of the factors that produce excessive cortisol and take steps to keep it in the normal, healthy range, then testing is probably not necessary.
Is cortisol related to abdominal obesity?
Yes. There is a link between high cortisol levels and storage of body fat, particularly “visceral” abdominal body fat (also known as intra-abdominal fat). Visceral fat is stored deeper in the abdominal cavity and around the internal organs, whereas “regular” fat is stored below the skin (known as subcutaneous fat). Visceral fat is particularly unhealthy because it is a risk factor for heart disease and diabetes.
Does cortisol make you fat?
No, cortisol is not “the thing” that makes you fat. In fact, one of the effects of cortisol is to increase the breakdown of stored adipose tissue into glycerol and fatty acids where it can enter the bloodstream and then be used as energy. High levels of cortisol are merely one contributing factor to storage of abdominal fat, not the primary cause. An excess of calories from too much food and not enough exercise is what makes you fat.
Is cortisol bad for you?
Cortisol is not “bad for you,” it is a hormone that is essential for life as part of our natural stress response. There are many hormones in our bodies, which in the proper amounts, maintain good health, but in excess or in deficiency, have negative effects or even contribute to health problems or diseases. Cortisol is no different. For example, Cushing’s syndrome is a disease of high cortisol levels, while Addison’s is a disease of low cortisol levels. You want to maintain a healthy, normal level of cortisol, not suppress your cortisol to nothing or allow it to remain elevated.
Chronically elevated cortisol levels may have a variety of negative effects. Cortisol is catabolic and elevated cortisol levels can cause the loss of muscle tissue by facilitating the process of converting lean tissue into glucose. An excess of cortisol can also lead to a decrease in insulin sensitivity, increased insulin resistance, reduced kidney function, hypertension, suppressed immune function, reduced growth hormone levels, and reduced connective tissue strength. Chronically elevated levels of cortisol can also decrease strength and performance in athletes.
Can suppressing cortisol increase improve your muscle growth and strength?
High cortisol levels can increase muscle protein breakdown and inhibit protein synthesis (building up muscle proteins), so a chronically elevated cortisol level is clearly counterproductive to building muscle. Bringing elevated cortisol levels back to normal may improve recovery, strength, hypertrophy and performance. However, there is no scientific evidence that reducing your cortisol levels below normal will have any effect on increasing strength or muscle growth.
Can you lower your cortisol levels naturally?
You can lower cortisol naturally. In fact, if you are over trained, unnatural cortisol suppression may be nothing more than a “band aid,” and continued overtraining can lead to adrenal exhaustion, which could take months to remedy. Sometimes the best thing you can do is take a rest or decrease your training volume and intensity rather than artificially attempt to suppress cortisol. Symptoms of overtraining include elevated resting pulse, sleep disturbances, fatigue, decreased strength and decreased performance.
Avoid very low calorie diets, especially for prolonged periods of time. Low calorie dieting is a major stress to the body. Low calorie diets increase cortisol while decreasing testosterone.
Use stress reduction techniques (stress, anger, anxiety, and fear can raise cortisol)
Avoid continuous stress. Stress is an important part of growth. It’s when you remain under constant stress without periods of recovery that you begin breaking down.
Avoid overtraining by keeping workouts intense, but brief (cortisol rises sharply after 45-60 min of strength training)
Avoid overtraining by matching your intensity, volume and duration to your recovery ability. Decrease your training frequency, and or take a layoff if necessary.
Suppress cortisol and maximize recovery after workouts with proper nutrition: Consume a carb-protein meal or drink immediately after your workout.
Get plenty of quality sleep (sleep deprivation, as a stressor, can raise cortisol).
Avoid or minimize use of stimulants; caffeine, ephedrine, synephrine, etc.
Limit alcohol (large doses of alcohol elevate cortisol).
Stay well hydrated (at least one study has suggested that dehydration may raise cortisol).
Excessive cortisol is not good. But cortisol is not inherently bad; it’s a vitally important hormone and part of your body’s natural stress response. Cortisol does not make you fat. Stress does not make you fat. Stress may lead to increased appetite… Increased appetite may lead to eating too much… Eating too much makes you gain fat. Make sense?
Get yourself on a solid exercise and nutrition program and seek natural ways to enhance recovery and reduce stress. You may be pleasantly surprised to find that you’re losing fat and gaining muscle!
