The size of the portions of food served in popular restaurants contributes to the increase in obesity. The conclusion is drawn from a study that measured and measured the caloric value of a complete meal in five countries: Brazil, China, Finland, Ghana, and India. With the exception of the Chinese meal, the caloric volume per prepared dish (PF), as they say in Brazil, is on average 33% higher than that of a quick snack.
Consumption portions served in popular restaurants provide between 70% and 120% of daily caloric needs of a sedentary woman, about 2,000 kilocalories (kcal).
"Health professionals who treat obese people are very worried Indicate to the Brazilian population Vivian Suen, Brazilian researcher in the Department of Clinical Medicine of the University of São Paulo at the Faculty of Medicine Ribeirão Preto (USP )
The study, coordinated by Tufts University and with the support of the Foundation for Research Support of the State of São Paulo (FAPESP), was published in the British Medical Journal
On average, the fast-food restaurants offered meals with 809 calories, while those served à la carte (included in the menu), 1317 kcal.The researcher warned that the result does not indicate that fast food is a healthier meal, because it has not been badyzed for each nutrient, but draws attention to the PF, which could be a balanced meal and would actually contribute to the gain.
In addition to the amount free food by restaurants in one meal, preparations have also been observed that increase the calorie gain. "The study did not focus on quality, but it can be said that this food is not healthy, both quantitatively and qualitatively."
You have to be careful with this dish, which is a complete meal, but it's not healthy, "he warned, with data showing that 94% of the à la carte and 72% of those served in fast foods contained more than 600 kcal, more than the energy consumption per meal recommended by the NHS.
the calories of 223 samples of popular dishes and 111 a la carte meals and fast foods randomly selected from restaurants in Ribeirão Perto (Brazil), Beijing (China), Kuopio (Finland), Accra (Ghana) and Bangalore (India) According to the measures, the traditional Brazilian PF, with rice, beans, chicken, cbadava , salad and bread, contains 841 grams and 1,656 kcal.The clbadic Ghanaian fufu, with meat and goat soup, contains 1,105 grams and 1,151 kcal.The typical lamb biryani dish contains 1,012 grams and 1,463 kcal.
Body resistance
Obesity is considered by WHO as a global epidemic. An estimated 1.9 billion adults are overweight, 600 million of whom are obese. "Diabetes, increased cholesterol, increased triglycerides, high blood pressure, all we know that accompanies obesity when it becomes a chronic disease", explains Vivian
. The researcher explains that exaggerated portions have an effect on the so-called compensatory mechanism. "These are people who can not compensate for the next meal what she has already eaten.The body of the obese develops defenses against weight loss." According to Vivian, the obese person would lose the perception of the amount of food needed for the next meal.
Another problem is that the body of the obese person creates resistance to weight loss. According to the researcher, there are cases described in the medical literature in which, as the caloric intake is reduced, the person in treatment begins to spend fewer calories. "It seems that the body, from a certain weight, tries"
Vivian says that it is best to prevent weight gain. "If you go into the one of those restaurants where the portion is excessive, divide "Once the person has gained weight, it is very difficult to lose," recommends the researcher, who advises him not to change the act of eating, how to chew slowly and give smaller bites in the food
