Know the Dangers of Weight Loss
But according to a research team from Kyungpook National University in Daegu, South Korea, weight loss also has side effects that can poison the blood by pollutants originating from the environment.
That’s because body fat contains pollutants such as pesticides and polychlorinated biphenyls (PCBs). If someone loses weight and a large amount of body fat is broken down, there are chemical compounds known as persistent organic pollutants. This compound is released and can cause diseases.
“The strong stigma of changes in weight is that weight loss is always good while weight gain is always bad. But it is not always the case,” said Dr. Duk-Hee Lee, the lead researcher, according to Healthnews.
“Hypertension, type 2 diabetes, coronary heart disease and rheumatoid arthritis have been associated with persistent organic pollutants,” said Lee. Researchers analyzed data collected by the Center for Disease Control and Prevention between 1999 and 2002.
They chose seven pollutants that have the highest detection rate in blood samples. Focused on 1,099 people aged 40 or older, who have the highest pollution levels measured in their blood and also experience weight loss or gain.
At the end of the study, researchers found that those who have lost weight had higher concentrations of pollutants. Meanwhile, those who have increased body weight have lower pollutan concentrations.
This tendency happens more significantly to those who experienced an increase or decrease in body weight over a period of 10 years.
“Many studies show that weight loss is very helpful to maintain a healthy body. Because it lowers fat and sugar levels in the blood. The effect is to stabilize blood pressure,” said Lee.
However, there are other health aspects that show the negative effects of weight loss. Especially if weight is dropped dramatically in a short time.
