Obesity is an abnormal accumulation of body fat usually 20% or more over an individuals ideal body weight. It rapidly increases the risk of diseases that can damage your health and knock years off your life, such as heart disease and diabetes.
Obesity is measured with a body mass index (BMI). It assesses your body weight relative to height. It’s a useful indirect measure of body composition because it correlates highly with body fat in most people. Individuals with a BMI of 25 to 29.9 are considered overweight, while individuals with a BMI of 30 or more are considered obese, while individuals with a BMI of above 40 are considered as morbid obesity . Morbid obesity is highly dangerous condition which in all probability will be the causitive factor of the death of the person.
Obesity is a complex medical condition caused by several factors. It is obvious that energy imbalance is the commonest cause. It means consuming too many calories or burning fewer calories. Eating too much, lack of physical activity, genetic factors, depression, hypothyroidism, cushing syndrome, poly cystic ovary syndrome , excessive alcohol intake, lack of sleep etc are some of the causes to become obese or overweight.
Obesity leads to severe serious problems like shorter life expectancy, diabetes (type2), joint problems (eg. Arthritis), high blood pressure, heart disease, gall bladder problems, certain type of cancer (breast, uterine, colon), digestive disorders (eg. Gastroesophageal reflux disease), breathing difficulties (eg. Sleep apnea), psychological problems such as depression , problems with fertility and pregnancy, urinary incontinence etc.
But body weight isn’t the only problem. The places where you store your body fat also affect your health. Women with a “pear” shape tend to store fat in their hips and buttocks. Women with an “apple” shape store fat around their waists.
Obesity can also affect medical care. Too much fat can obscure imaging tests, like X-rays, CT scans, ultrasound, and magnetic resonance imaging (MRI). For example, in an ultrasound, the beam not able to get through layers of fat to get an image of a person’s appendix, gallbladder, or kidneys. Too much body fat can make it harder for a doctor to make a medical diagnosis and treat a patient.
Skipping any meal during the day will lower your metabolic rate which will lead to reduced rate of burning the calories in your body. Skipping breakfast, in particular, not only reduces the metabolic rate, it may add to undesirable craving for high carbohydrate foods like sweets as you are hypoglycemic .
