Study confirms association between fast food consumption, weight gain and insulin resistance

In a recently published study, American scientists came to the conclusion that increased consumption of fast food is closely related to weight gain and insulin resistance, reports today graduate oecotrophologist Ann-Margret Heyenga from the Society for Nutritional Medicine and Dietetics in Aachen.

The insulin resistance caused by obesity and lack of exercise leads to type 2 diabetes mellitus. In the CARDIA study [1], the researchers from the University of Minnesota and the Children's Hospital in Boston compared data on body weight and insulin resistance in 3,031 American subjects over a period of 15 years of different ethnic origins. In addition, the experts used a questionnaire to regularly survey the test persons between the ages of 18 and 30 about their eating habits and the frequency of visits to fast food restaurants.

The researchers concluded that fast food eating habits show a strong positive association with weight gain and insulin resistance in young Americans, dark and white. Overall, white young adults, with an average of 1.3 visits per week in a fast food restaurant, consumed less fast food than groups of dark skin color with an average of two visits per week.

The study participants who ate fast food more than twice a week showed - in both ethnic groups - a doubling of the increase in insulin resistance with a simultaneous weight gain of 4.5 kilograms. Unilateral fast food eating habits are directly linked to diseases such as obesity and type 2 diabetes.

So if you have little exercise at work or privately, you should eat fast food consciously and not too often. A mineral water or a light drink instead of a sugary soft drink, or a low-calorie salad instead of fatty fries save a lot of calories, emphasizes Ann-Margret Heyenga in conclusion.
