Obesity worldwide has almost tripled from 1975 to the present.In 2016, more than 1.9 billion adults were overweight, of whom more than 650 million were obese.

Among us, 41 million children under the age of five are obese, and more than 340 million children and adolescents between the ages of 5 and 19 are obese in 2016.

Disturbing data is repeated by the World Health Organization to our ears, in a world where obese people are dying at a much higher rate than very thin, often blaming bad diets and working on offices without movement and genetic factors, but do you think that if you use exactly the same methods to stay on Your father's body, will your weight be the same as him? The answer is no.

10% heavier today
NEW YORK (Reuters Health) - People who eat and exercise the physical activity of a person of their age in the 1980s will be fatter, a new study finds, making it difficult for today's youth to maintain the weight of those aged 20 to 30, even with the same levels of food intake and exercise. .

This came as a result of a study in which a team from the University of York in Canada analyzed the nutritional data of 36,400 Americans between 1971 and 2008, and divided the participants into groups according to the amount of food, daily activity, age and body mass index, to find a surprising relationship.

If a person in 2006 consumes the same number of calories and the same amount of protein and fat and does the same activity as a person of the same age in 1988, the BMI of the first person will be about 2.3 points higher.

The simplest explanation is that humans today are about 10% heavier than those who lived in the 1980s, even if they followed the same diet and exercised the same exercise plans. The results of the study suggest that if you are now 40 years old you should eat less and exercise more, I was 40 years old in 1971, to prevent weight gain, this is certainly puzzling.

Tax on living in the 21st century
Jennifer Cook, professor of kinesiology and health sciences at the University of York in Toronto, said the results of her study suggest that if you are 25 years old, you should eat less and exercise more than the elderly - at a time when they were the same - to prevent an increase. Weight, though, may be other specific changes contribute to the high rates of obesity, namely the tax of living in this age.

The researchers hypothesized three reasons why it is difficult for today's youth to reach an ideal weight, which makes sense that may make you accept these kilograms a little, namely:

1. Humans are exposed to more chemicals that may lead to weight gain. Insecticides in vegetables, clothing, flame retardants in furniture, preservatives in food containers, packaging bags, plastics and detergents may alter our hormonal system, disrupting the way our bodies gain. Weight and get rid of it.

With research revealing the dangers of these chemicals, which limit us from each side - for more serious reasons than being overweight - some countries have taken decisions to ban them from making detergents and beauty products such as the European Union and Canada, which banned about 1,300 substances, but the US and China continue to produce red. Lips and skin lotion contain these substances.

The use of prescription drugs has risen dramatically since the 1970s and 1980s, and the emergence of Prozac, the most popular depression drug in 1988, was an event at the time.

Some of those prescribed drugs feel more hungry, and are likely to change the way the body burns its energy, and in some cases the body stores energy and fluids.

The impact of drugs on the prevalence of obesity increases over time, especially since the number of people in the United States that depend on it has increased by 10% since the late 1980s, and one in 10 Americans now take five or more prescription drugs regularly.

3. The authors believe that viruses, fungi, bacteria, and other living organisms on the human body and intestines, called microbium, may have changed in some way from the 1980s to the present, and contain various groups that perform different functions in the body. From influencing external behavior, to turning food into energy and regulating our appetite.

It is known that some types of intestinal bacteria make a person more susceptible to overweight and obesity, and what hurts the work of these microbes that we are eating more meat than humans decades ago, with less fiber and higher fat, with all the products contained animal hormones today And additional antibiotics to stimulate growth.

As a result of our uncontrolled microbes and the interactions of our bodies with chemicals and medicines, our bodies have become relatively larger than they were decades ago, requiring more effort, although it cannot be overlooked that thinness does not necessarily mean that your health is good.
