Why is obesity obsolete?

Nutritional prognosis People always need more calories

Professor Peter Schwarz is currently in Saudi Arabia teaching doctors how to deal with overweight people.

I was just in a hospital and saw a 13-year-old child who weighs 180 kilos.

37 percent of people in Saudi Arabia live with diabetes, says Schwarz. He heads the professorship for prevention and care of diabetes at the medical faculty in Dresden. His prognosis for the state in the Middle East: In ten years, more than 50 percent there will be living with diabetes. His explanation for this development:

Here it is clearly the diet. During the day a lot of high-fat, sweet dishes are eaten here and one moves very little because that is frowned upon.

Countries like Saudi Arabia are boosting the global calorie requirement because fat people automatically need more food to maintain their body mass.

Take Mexico, for example: calorie requirement increased eleven times

Göttingen development economists have now calculated for the first time how much the global calorie requirement will increase and have made a prognosis for the year 2100. To do this, they looked at all the continents. The researchers chose Mexico as an example for their calculations. A country where people have put on weight in the past decades, as Lutz Depenbusch, development economist from the University of Göttingen explains:

D.The male BMI in 1975 was 23.57. In 2014 it rose to 27.47. This means that during this time the number of people who are overweight has risen from 0.8 million to 8.9 million. So that has increased eightfold - a really, really big increase.

Lutz Depenbusch

The number of overweight women has also increased since 1975 from around two to 14 million. Here too, the reason is too little exercise and bad food.

E.More foods are eaten that are high in calories, especially a lot of fried food, also lots of sugary drinks and the cola for lunch.

The global calorie requirement will increase by 80 percent

Depenbusch predicts this development for many countries, especially in regions south of the Sahara. Asia, Europe, North and South America, on the other hand, should expect stable or even falling demand, the study predicts. Taken together, including population growth, the global calorie requirement will have increased by 80 percent by 2100 compared to today. Germany, too, would drive this number high, predicts scientist Peter Schwarz:

In Germany, too, we can see that obesity continues to rise.

Peter Black

Germans still eat too much sugar, says Peter Schwarz, or sugar additives that ultimately increase hunger, too much fast food or unhealthy fats. "We talk a lot about our diet," says Schwarz, "but we haven't made any fundamental changes." The diabetes expert would like to see government control in Germany, for example taxes on sugar. They already exist in Mexico.
