Definition of overweight
One way to calculate body fat is by measuring your waist. A waist that measures more than 35 inches in women and more than 40 inches in men is considered high risk. Another way to measure obesity is with the index is according to the index (BMI) which is calculated by dividing the kilograms of weight by the square of the height in meters (BMI = kg / m2) .
Causes of obesity
In certain people, the cause of obesity is very simple: they eat more calories than they burn by exercising in their daily lives. There are other causes of obesity, which are:
- Sex : men tend to burn more calories while at rest than women, for this reason they require more calories to maintain their body weight. Women mostly gain weight after menopause as their energy capacity is further minimized.
- Genetic inheritance : Obesity tends to run in families. Some researchers believe that a gene that is passed from one generation to the next can negatively influence the way we regulate our body weight.
- Age : with age, the body finds it difficult to burn fat as quickly and we do not require the same amount of calories to maintain balanced weight. That is why people who consume in the same way and perform the same activities as at 20 years of age, gain weight at 40 years.
- Environment and eating habits: fast food restaurants and junk food with excess fat and cholesterol have become a main component of the US diet.
- Pregnancy : Although women only gain a few pounds a year after giving birth, at least 15% of women gain pounds with each pregnancy.
- Diseases : certain obesities can cause obesity. These include hormonal problems as well as poor functioning of the thyroid gland (hypothyroidism), depression, and some rare brain diseases.
- Childhood obesity : Obese children have a high probability of being obese adults. The researchers affirm that the fat cells that we obtain in childhood remain in the body as we step into adulthood. Obese children are likely to have five times the number of fat cells as normal-weight children. In adulthood, diets can reduce the size of fat cells, but not the amount.
- Lack of physical activity: that people who consume excessively but do not do any type of exercise have a greater chance of being obese.
- Medications : there are some antidepressants and corticosteroids that can cause weight gain.
- Eating Disorders : Eating disorders at night or binge-eating account for as many as 10 to 20 percent of people who require treatment.
Risks of obesity
An excessive amount of body fat contributes to an increased risk of health problems, specifically stroke and cardiovascular disease. Even being overweight can:
- Increase the risk of asthma in adults and other respiratory problems.
- Raise blood pressure
- Lower the levels of good cholesterol or HDL.
- Produce diabetes.
- Increase the risk of destructive sleep apnea (OSA).
- Raises your risk of certain types of cancer, such as breast cancer, endometrial cancer, colon cancer, and prostate cancer.
Although we are not exposed to other risk factors, obesity alone increases cardiovascular risk . It even affects the heart and blood vessels. Being overweight puts a strain on your bones, joints, and muscles.
