How weight loss can help you fight aging
research in progress
Obesity I the state of a person being very overweight with a lot of body fat. The common method to calculate obesity is using the Body Mass Index (BMI). It is a measure of how healthy you are given your height and weight. Obesity begins with a BMI score of 30 and above. This is not an absolute calculation and there are other ways of measuring.
Obesity, other than causing the obvious physical changes can lead to a several potentially life-threatening conditions. Short term or day-to-day symptoms associated with obesity include breathlessness, snoring, increased sweating, excessive exhaustion over menial tasks, low confidence and self-esteem, difficulty doing any physical activity and a general feeling of isolation. Psychological problems that are linked to obesity have been found to affect relationships with friends and family members. It may also lead to depression.
Obesity increases your risk of developing potentially fatal health conditions. These include type 2 diabetes, high blood pressure and cholesterol, asthma, cancer, gallstones, gastro-oesophageal reflux disease, reduced fertility, sleep apnea, liver disease and pregnancy complications. Research has found that obesity reduces your life expectancy by 3 to 10 years.
In this article, we will focus on the effect obesity has on ageing. Obesity, as we mentioned above comes with a host of other problems. When too much cholesterol is in the blood, plaque may form in the arteries causing cardiovascular disease such as heart attacks. This is because there is insufficient blood flow in the body. This contributes to ageing because, the skin, being the largest organ, requires adequate blood supply for it to function properly. Proteins responsible for skin elasticity and tautness are transported in the blood. If these are insufficient, the skin becomes saggy, wrinkled and greyish.
People suffering from obesity tend to lead fairly sedentary lifestyles. This means that they barely get any exercise done. Exercise helps reduce inflammation that comes with ageing. Inflammation is linked to many chronic illnesses and has been found to be the common factor in many of them. It is also common knowledge that people who are overweight or obese look and feel much older than they actually are. The worst thing about it is that obesity causes a decrease in energy levels in the body and the continued intake of unhealthy foods promotes the burning of sugar instead of fat. This means that people suffering from the disease only get bigger and weaker if they do not make significant lifestyle changes.
When a person is overweight or obese, their bones and joints experience a lot of pressure. This makes them brittle and decreases bone density. You can find fairly young people unable to do simple tasks like walking.
One of the biggest downfalls of obesity is its degeneration of brain cells. This is caused by a number of factors such as low levels of antioxidants in your diet, constricted blood vessels and a decrease in the production of BDNF. Exercise slows down brain ageing by producing higher BDNF which increases cognitive function.
Exercise and resultant weight loss is an inexpensive way to combat the degenerative features of ageing. If you are a beginner, start slow and work your way to higher intensity exercise.
