Cortisol and Weight Gain

Whether you have recently lost a job, started a new one, have any kind of crisis in your life (and who doesn't?) the added stress can make it difficult to lose weight. Stress causes your adrenal gland to secrete more Cortisol (the stress hormone). Cortisol can increase your appetite, but also stimulates your body's release of the fat-storing hormone insulin. The result: Your body holds on to its fat stores as hard as it can, even if you're eating less than before.

Anyone that has struggled with Cushing's Disease can tell you what a MAJOR impact cortisol can have on weight gain. Hormones regulate almost every cell and organ, and function in our body. In an earlier post we mentioned the hormone ghrelin as a hormone that stimulates appetite. Cortisol is known as the “stress hormone” due to excess cortisol being excreted during times of physical and physiological stress. Cortisol has been shown to not only affect weight gain, but also where weight is put on. An elevation in cortisol levels has been shown to cause fat deposition in the abdominal area. A high amount of fat in the abdominal area has been correlated with cardiovascular disease, heart disease and stroke.

This was a brief explanation about how high cortisol levels and weight gain are related to each other. High levels of cortisol for a prolonged duration doesn't just cause weight gain, but also causes muscle pain, premature aging, insomnia etc. Cortisol release in blood flow increases when a person is under stress.
Through the science of getting thin a new product has been introduced that acts favorably with the glandular system of the body to nutritionally support optimal levels of weight related hormones including Cortisol and Grehlin. The product , called Transfigure has been developed to synergistically work with the other products in SISEL’s Slim & Slender Rapid Weight Loss System. It is exciting to know that science is working to make things easier in life, and explain some of the many factors that make losing weight  so difficult.

Metabolism and Weight

Many of us find it harder and harder to lose weight, even that five pounds we used to shed in a week for a new party dress. Remember those days? 

"If you never had problems losing or maintaining your weight in your 20s or even in your early 30s, you may not be ready for what happens next,” warns Madelyn H. Fernstrom, Ph.D., director of the Weight Management Center at the University of Pittsburgh Medical Center. “Your metabolism slows by 5 percent each decade. Compared to age 25, you’ll burn about 100 fewer calories a day at 35 and 200 fewer at 45. Do nothing, and you could gain eight to 12 pounds a year.”

With age, muscle mass diminishes and so does your metabolic rate (the number of calories your body burns throughout the day, whether you’re sleeping, sitting, or sprinting to catch a bus). " (From GoodhouseKeeping)

In fact as you age your basal metabolic rate (bmr) drops by two per cent for every decade of your life. Also, you lose 3.2kg (7lbs) of lean body mass with every decade, which is replaced by fat. Therefore, as you get older you need to change what you do to stay fit, slim and toned - you need to do more exercise to turn back the clock.

Another thing that affects metabolism is smoking. We all know NOW is the time to quit...but what will it do to our weight? The nicotine in cigarettes acts as an appetite suppressant. The nicotine may slightly increase your metabolism as well. When you quit smoking, your appetite and metabolism return to normal — which may lead you to eat more and burn fewer calories. Also, your ability to smell and taste food improves after you quit smoking. This can make food more appealing, which may lead you to eat more. And if you substitute snacking for smoking, the calories may quickly add up.  (Mayo Clinic)

Considering all of the facts, it is only reasonable that science would start working on ways to help moderate these changes in metabolism. The incredible progress made here can help attain and maintain a healthy weight.
