Obesity shortens life, in some cases no less than smoking, for example, warn scientists from the University of Oxford in the Lancet. Their findings are the result of an analysis of a total of more than 57 clinical trials conducted in Europe and the United States over the past 10-15 years. They used the Body Mass Index marker. By definition, overweight is between 25 and 29, and obesity is between 25 and 29.

Life expectancy is highest at values between 23 and 24. People with an index of about 30-35 lose an average of 3 years of life, and those with an index over 40 - at least ten, similar to long-term smoking. Not only that, observations show that obese people are 60% more likely to die after myocardial infarction or stroke. The risk of diabetes, nephropathy or liver damage is even higher. The susceptibility to malignancies is also not to be underestimated.

With the research, doctors want to emphasize how many negative consequences weight has on our health. Complications of abnormalities are also not to be overlooked.
